Description

本発明は、空調対象空間に供給する供給用空気の給気風路に通風作用する給気送風手段と、
空調対象空間外に排出する排出用空気の排気風路に通風作用する排気送風手段と、
一部を前記給気風路に位置させ且つ他の一部を前記排気風路に位置させるように配置される調湿体、及び、その調湿体における前記給気風路に位置させる部分及び前記排気風路に位置させる部分を回転に伴って変更させるように前記調湿体を駆動回転する調湿用駆動手段を備えた調湿手段と、
前記給気風路における前記調湿体よりも通風方向上手側箇所又は前記排気風路における前記調湿体よりも通風方向上手側箇所にて、通流する空気に対して加熱作用する加熱手段と、
一部を前記給気風路に位置させ且つ他の一部を前記排気風路に位置させるように配置される顕熱交換体を備えた顕熱交換手段とが設けられた空調装置に関する。
The present invention provides an air supply / air blowing means that ventilates an air supply passage for supplying air to be supplied to an air-conditioning target space,
An exhaust air blowing means for ventilating the exhaust air path of the discharge air discharged outside the air-conditioning target space;
A humidity control body arranged so that a part is located in the air supply air passage and another part is located in the exhaust air air passage, and a portion of the humidity control body located in the air supply air passage and the exhaust Humidity control means comprising humidity control drive means for driving and rotating the humidity control body so as to change the portion positioned in the air path with rotation;
A heating means that heats the air that flows in the ventilation direction upper side of the humidity control body in the supply air path or in the ventilation direction upper side of the humidity control body in the exhaust air path;
The present invention relates to an air conditioner provided with sensible heat exchange means including a sensible heat exchanger arranged so that a part is located in the supply air passage and another part is located in the exhaust air passage.

かかる空調装置は、供給用空気を調湿手段にて加湿して空調対象空間に供給する加湿運転、又は、供給用空気を調湿手段にて除湿して空調対象空間に供給する除湿運転を行うようにして、空調対象空間を加湿又は除湿するものである。   Such an air conditioner performs a humidifying operation in which supply air is humidified by the humidity control means and supplied to the air conditioning target space, or a dehumidification operation in which the supply air is dehumidified by the humidity control means and supplied to the air conditioning target space. In this way, the air-conditioning target space is humidified or dehumidified.

つまり、加湿運転を行うようにする場合は、加熱手段を給気風路における調湿体よりも通風方向上手側箇所に設け、顕熱交換体を、その一部を給気風路における加熱手段よりも通風方向上手側箇所に位置させ且つ他の一部を排気風路における調湿体よりも通風方向下手側箇所に位置させるように配置する。
そして、調湿体を回転させ、加熱手段を加熱作用させて運転することにより、供給用空気を、顕熱交換体を通過させることで排出用空気との顕熱交換により加熱し、更に、加熱手段を通過させることで加熱した後に、調湿体を通過させて加湿して、空調対象空間に供給する。
In other words, when performing the humidification operation, the heating means is provided at a location on the upper side of the ventilation direction with respect to the humidity control body in the air supply air passage, and a part of the sensible heat exchanger is more than the heating means in the air supply air passage. It arrange | positions so that it may be located in the ventilation direction upper side location, and may be located in the ventilation direction lower side location rather than the humidity control body in an exhaust air path.
Then, by rotating the humidity control body and operating the heating means by heating, the supply air is heated by sensible heat exchange with the discharge air by passing through the sensible heat exchanger, and further the heating After heating by passing the means, the humidity control body is passed and humidified, and supplied to the air-conditioning target space.

又、除湿運転を行うようにする場合は、加熱手段を排気風路における調湿体よりも通風方向上手側箇所に設け、顕熱交換体を、その一部を給気風路における調湿体よりも通風方向下手側箇所に位置させ且つ他の一部を排気風路における加熱手段よりも通風方向上手側箇所に位置させるように配置する。
そして、調湿体を回転させ、加熱手段を加熱作用させて運転することにより、供給用空気を、調湿体を通過させることで除湿し、更に、顕熱交換体を通過させることで排出用空気との顕熱交換により冷却して、空調対象空間に供給する(例えば、特許文献1参照。)。
Also, when performing the dehumidifying operation, the heating means is provided at a location on the upper side of the ventilation direction with respect to the humidity control body in the exhaust air passage, and the sensible heat exchanger is partially provided by the humidity control body in the air supply air path. Also, it is arranged so that it is positioned at the lower side in the ventilation direction and the other part is positioned at the upper side in the ventilation direction than the heating means in the exhaust air passage.
Then, by rotating the humidity control body and operating the heating means by heating, the supply air is dehumidified by passing through the humidity control body, and further passing through the sensible heat exchanger for discharge. It cools by sensible heat exchange with air, and supplies it to air-conditioning object space (for example, refer patent document 1).

ところで、空調対象空間を空調するに当たって、加湿運転又は除湿運転とは別に、供給用空気と排出用空気との間で熱交換させるだけの運転が望まれる場合がある。
例えば、外気を供給用空気として空調対象空間に供給し、空調対象空間内の空気を排出用空気として空調対象空間外に排出するようにして、第1種換気を行う場合、冬期等、この空調装置とは別の空調装置により空調対象空間が暖房されているときに、空調対象空間の湿度が快適な状態では、供給用空気と排出用空気との間で熱交換させるように運転すると、暖房に係わる消費エネルギを削減することが可能となる。
又、夏期等、この空調装置とは別の空調装置により空調対象空間が冷房されているときに、空調対象空間の湿度が快適な場合は、供給用空気と排出用空気との間で熱交換させるように運転すると、冷房に係わる消費エネルギを削減することが可能となる。
By the way, when air-conditioning the air-conditioning target space, there may be a case where an operation that only causes heat exchange between the supply air and the discharge air is desired in addition to the humidification operation or the dehumidification operation.
For example, when the first type ventilation is performed by supplying the outside air as supply air to the air-conditioning target space and discharging the air in the air-conditioning target space as the discharge air outside the air-conditioning target space, this air conditioning is performed in the winter season or the like. When the air conditioning target space is heated by an air conditioner different from the device and the humidity of the air conditioning target space is in a comfortable state, heating is performed so that heat is exchanged between the supply air and the discharge air. It becomes possible to reduce the energy consumption related to.
In addition, when the air-conditioning space is cooled by an air-conditioning device other than this air-conditioning device, such as in summer, when the humidity of the air-conditioning space is comfortable, heat exchange is performed between supply air and discharge air. When the operation is performed, it is possible to reduce energy consumption related to cooling.

そして、従来の空調装置において、供給用空気と排出用空気との間で熱交換させるだけの運転を行うには、調湿体を停止させ且つ加熱手段を加熱停止状態にして、顕熱交換体により供給用空気と排出用空気との間で顕熱を交換させることできる。尚、ちなみに、前記顕熱交換手段が、顕熱交換体における給気風路に位置させる部分及び排気風路に位置させる部分を回転に伴って変更させるように顕熱交換体を駆動回転する顕熱交換用駆動手段を備えて、回転型に構成される場合があり、この場合は、供給用空気と排出用空気との間の顕熱交換量をより増大させることができる。   And in the conventional air conditioner, in order to perform an operation of only exchanging heat between the supply air and the discharge air, the humidity control body is stopped and the heating means is stopped, and the sensible heat exchanger Thus, the sensible heat can be exchanged between the supply air and the discharge air. Incidentally, the sensible heat that drives and rotates the sensible heat exchanger so that the sensible heat exchange means changes the portion located in the supply air passage and the portion located in the exhaust air passage in the sensible heat exchanger with rotation. In some cases, a replacement type drive unit is provided and a rotary type is configured. In this case, the amount of sensible heat exchange between the supply air and the discharge air can be further increased.

しかしながら、顕熱交換体により供給用空気と排出用空気との間で顕熱を交換させるだけでは、供給用空気と排出用空気との間のエンタルピー交換効率を十分に増大することができず、例えば、暖房や冷房に係わる消費エネルギーを十分に削減することができなかった。
又、供給用空気と排出用空気との間のエンタルピー交換効率を増大するには、既設の顕熱交換手段の顕熱交換体を大型化したり、顕熱交換手段を増設すること等が考えられるが、空調装置が大型化することになる。
However, the enthalpy exchange efficiency between the supply air and the discharge air cannot be increased sufficiently only by exchanging the sensible heat between the supply air and the discharge air by the sensible heat exchanger, For example, energy consumption related to heating and cooling could not be reduced sufficiently.
In order to increase the enthalpy exchange efficiency between the supply air and the discharge air, it is conceivable to enlarge the sensible heat exchanger of the existing sensible heat exchange means or increase the number of sensible heat exchange means. However, an air conditioner will be enlarged.

本発明は、かかる実情に鑑みてなされたものであり、その目的は、空調装置の大型化を回避しながら、供給用空気と排出用空気との間のエンタルピー交換効率を増大するように運転し得る空調装置を提供することにある。   The present invention has been made in view of such circumstances, and its purpose is to operate so as to increase the enthalpy exchange efficiency between supply air and discharge air while avoiding an increase in the size of the air conditioner. It is to provide an air conditioner to obtain.

本発明の空調装置は、空調対象空間に供給する供給用空気の給気風路に通風作用する給気送風手段と、
空調対象空間外に排出する排出用空気の排気風路に通風作用する排気送風手段と、
一部を前記給気風路に位置させ且つ他の一部を前記排気風路に位置させるように配置される調湿体、及び、その調湿体における前記給気風路に位置させる部分及び前記排気風路に位置させる部分を回転に伴って変更させるように前記調湿体を駆動回転する調湿用駆動手段を備えた調湿手段と、
前記給気風路における前記調湿体よりも通風方向上手側箇所又は前記排気風路における前記調湿体よりも通風方向上手側箇所にて、通流する空気に対して加熱作用する加熱手段と、
一部を前記給気風路に位置させ且つ他の一部を前記排気風路に位置させるように配置される顕熱交換体を備えた顕熱交換手段とが設けられたものであって、
第1特徴構成は、前記調湿手段が、前記調湿体の駆動回転速度を変更調節自在に構成され、
前記加熱手段が、加熱作用状態と加熱停止状態とに切り換え自在に構成されている点を特徴とする。
The air conditioner of the present invention includes an air supply air blowing means that ventilates an air supply air passage for supply air supplied to the air conditioning target space,
An exhaust air blowing means for ventilating the exhaust air path of the discharge air discharged outside the air-conditioning target space;
A humidity control body arranged so that a part is located in the air supply air passage and another part is located in the exhaust air air passage, and a portion of the humidity control body located in the air supply air passage and the exhaust Humidity control means comprising humidity control drive means for driving and rotating the humidity control body so as to change the portion positioned in the air path with rotation;
A heating means that heats the air that flows in the ventilation direction upper side of the humidity control body in the supply air path or in the ventilation direction upper side of the humidity control body in the exhaust air path;
Sensible heat exchange means including a sensible heat exchanger arranged so that a part is located in the supply air path and another part is located in the exhaust air path,
The first characteristic configuration is configured such that the humidity control means is capable of changing and adjusting the drive rotation speed of the humidity control body,
The heating means is configured to be switchable between a heating operation state and a heating stop state.

即ち、調湿手段が調湿体の駆動回転速度を変更調節自在に構成され、又、加熱手段が加熱作用状態と加熱停止状態とに切り換え自在に構成されているから、調湿体を供給用空気の加湿又は除湿に適した駆動回転速度にて回転駆動し且つ加熱手段を加熱作用状態にして行う加湿運転又は除湿運転に加えて、調湿体を加湿運転時又は除湿運転時よりも高速の駆動回転速度にて回転駆動し且つ加熱手段を加熱停止状態にして行う運転(以下、全熱・顕熱交換運転と記載する場合がある)を行うことができる。   That is, the humidity control means is configured to be able to change and adjust the drive rotation speed of the humidity control body, and the heating means is configured to be switchable between a heating operation state and a heating stop state, so that the humidity control body can be supplied. In addition to the humidification operation or dehumidification operation that is driven to rotate at a driving rotation speed suitable for humidification or dehumidification of air and the heating means is in a heating action state, the humidity control body is faster than the humidification operation or the dehumidification operation. It is possible to perform an operation (hereinafter sometimes referred to as a total heat / sensible heat exchange operation) that is rotationally driven at a driving rotational speed and is performed with the heating means in a heating stopped state.

つまり、回転駆動されている調湿体に供給用空気及び排出用空気を通過させると、供給用空気と排出用空気との温度差により供給用空気と排出用空気との間で顕熱を交換させると共に、湿度差により供給用空気と排出用空気との間で潜熱を交換させることが可能であって、供給用空気と排出用空気との間で全熱を交換させることが可能であるが、本願発明の発明者は、鋭意研究して、調湿体の駆動回転速度を高くすることにより、調湿体において、そこを通過する供給用空気と排出用空気との間の全熱交換量を多くすることが可能であることを見出した。
このことについて考察すると、調湿体の駆動回転速度を高くすることにより、調湿体が給気風路や排気風路を移動する速度が速くなるので、調湿体と供給用空気や排出用空気との間で顕熱及び潜熱の交換を十分に行わせながら、調湿体における、供給用空気や排出用空気との間で顕熱及び潜熱の交換が行われた部分を速く移動させることが可能となり、調湿体での供給用空気や排出用空気との間の全熱交換量を多くすることができるのである。
In other words, when supply air and discharge air are passed through a rotationally driven humidity control body, the sensible heat is exchanged between the supply air and the discharge air due to the temperature difference between the supply air and the discharge air. In addition, the latent heat can be exchanged between the supply air and the discharge air due to the humidity difference, and the total heat can be exchanged between the supply air and the discharge air. The inventor of the present invention has earnestly studied, and by increasing the driving rotational speed of the humidity control body, the total heat exchange amount between the supply air and the discharge air passing therethrough in the humidity control body It was found that it is possible to increase a lot.
Considering this, since the speed at which the humidity control body moves through the air supply and exhaust air passages increases by increasing the drive rotation speed of the humidity control body, the humidity control body and the supply air and exhaust air The sensible heat and latent heat exchange between the sensible heat and the latent air can be quickly moved between the supply air and the discharge air in the humidity control body. Thus, the total heat exchange amount between the supply air and the discharge air in the humidity control body can be increased.

そして、上述のようにして全熱・顕熱交換運転を行うと、調湿体においては、供給用空気と排出用空気との間で全熱交換量をより多くする状態で全熱交換させることができ、又、顕熱交換体においては、供給用空気と排出用空気との間で顕熱交換させることができるので、供給用空気と排出用空気との間のエンタルピー交換効率を十分に増大することが可能となり、例えば、暖房や冷房に係わる消費エネルギーを十分に削減することが可能となるのである。
従って、空調装置の大型化を回避しながら、供給用空気と排出用空気との間のエンタルピー交換効率を増大するように運転し得る空調装置を提供することができるようになった。
When the total heat / sensible heat exchange operation is performed as described above, in the humidity control body, the total heat exchange is performed in a state where the total heat exchange amount is increased between the supply air and the discharge air. In the sensible heat exchanger, sensible heat exchange can be performed between the supply air and the discharge air, so that the enthalpy exchange efficiency between the supply air and the discharge air is sufficiently increased. For example, the energy consumed for heating and cooling can be sufficiently reduced.
Accordingly, it is possible to provide an air conditioner that can be operated to increase the enthalpy exchange efficiency between the supply air and the discharge air while avoiding an increase in the size of the air conditioner.

第2特徴構成は、上記第1特徴構成に加えて、
前記加熱手段が前記給気風路における前記調湿体よりも通風方向上手側箇所に設けられ、且つ、前記顕熱交換体がその一部を前記給気風路における前記加熱手段よりも通風方向上手側箇所に位置させ且つ他の一部を前記排気風路における前記調湿体よりも通風方向下手側箇所に位置させるように配置されて、前記供給用空気を前記顕熱交換手段にて加熱した後に、前記調湿手段にて加湿するように構成され、
前記調湿体を通過し且つ前記顕熱交換体を通過する前の排出用空気の一部を、前記給気風路における前記顕熱交換体と前記加熱手段との間の箇所に導く供給用導風部が設けられている点を特徴とする。
In addition to the first feature configuration, the second feature configuration is
The heating means is provided at a location on the upper side in the ventilation direction with respect to the humidity control body in the supply air passage, and a part of the sensible heat exchanger is on the upper side in the ventilation direction with respect to the heating means in the supply air passage. After being heated by the sensible heat exchanging means, the air is disposed at a location and the other part is positioned at a location on the lower side in the ventilation direction than the humidity control body in the exhaust air passage. And configured to humidify by the humidity control means,
A supply guide for guiding a part of the exhaust air that has passed through the humidity control body and before passing through the sensible heat exchanger to a location between the sensible heat exchanger and the heating means in the supply air passage. It is characterized in that a wind part is provided.

即ち、調湿体を通過し且つ顕熱交換体を通過する前の排出用空気の一部が、供給用導風部を通じて給気風路における顕熱交換体と加熱手段との間の箇所に導かれながら、排出用空気が、調湿体、顕熱交換体を順次通過して通流し、供給用空気が、顕熱交換体、加熱手段、調湿体を順次通過して通流する。
つまり、加熱手段を加熱作用状態にすると、排出用空気は、調湿体を通過するときに、その排出用空気中の水蒸気が調湿体に吸収されると共に凝縮熱により加熱され、その排出用空気が顕熱交換体を通過するときに、その保有熱が顕熱交換体に与えられて顕熱交換体が加熱され、供給用空気は、顕熱交換体を通過することで加熱され、更に、加熱手段を通過することで加熱され、その供給用空気が調湿体を通過するときに加湿されるので、供給用空気を加湿する加湿運転を行うことができる。
That is, a part of the discharge air that has passed through the humidity control body and before passing through the sensible heat exchanger is guided to a location between the sensible heat exchanger and the heating means in the supply air passage through the supply air guide section. While being discharged, the discharge air passes through the humidity control body and the sensible heat exchanger in order, and the supply air passes through the sensible heat exchanger, the heating means, and the humidity control body in order.
In other words, when the heating means is in the heating action state, when the exhaust air passes through the humidity control body, water vapor in the exhaust air is absorbed by the humidity control body and is heated by the condensation heat, and the exhaust air is discharged. When the air passes through the sensible heat exchanger, the retained heat is given to the sensible heat exchanger to heat the sensible heat exchanger, and the supply air is heated by passing through the sensible heat exchanger, Since the air is heated by passing through the heating means and the supply air passes through the humidity control body, the humidification operation of humidifying the supply air can be performed.

そして、調湿体を通過し且つ顕熱交換体を通過する前の高温の排出用空気の一部が、給気風路における顕熱交換体と加熱手段との間の箇所に導かれて供給用空気に混合されるので、調湿体を通過する供給用空気の風量を多くすることができ、空調対象空間をより早く加湿及び暖房することが可能となる。又、加熱手段にて供給用空気を加熱するために要するエネルギー量を低減することが可能となる。
従って、加湿運転が可能な空調装置において、消費エネルギーを低減しながら、空調対象空間の加湿及び暖房性能の向上を図ることができるようになった。
Then, a part of the high-temperature exhaust air that has passed through the humidity control body and before passing through the sensible heat exchanger is led to a location between the sensible heat exchanger and the heating means in the supply air passage. Since it is mixed with air, the air volume of the supply air that passes through the humidity control body can be increased, and the air-conditioning target space can be humidified and heated more quickly. Further, it is possible to reduce the amount of energy required for heating the supply air by the heating means.
Therefore, in an air conditioner capable of humidification operation, it has become possible to improve the humidification and heating performance of the air-conditioning target space while reducing energy consumption.

第3特徴構成は、上記第1特徴構成に加えて、
前記加熱手段が前記排気風路における前記調湿体よりも通風方向上手側箇所に設けられ、且つ、前記顕熱交換体がその一部を前記給気風路における前記調湿体よりも通風方向下手側箇所に位置させ且つ他の一部を前記排気風路における前記加熱手段よりも通風方向上手側箇所に位置させるように配置されて、前記供給用空気を前記調湿手段にて除湿した後に、前記顕熱交換手段にて冷却するように構成され、
前記調湿体を通過し且つ前記顕熱交換体を通過する前の供給用空気の一部を、前記排気風路における前記顕熱交換体と前記加熱手段との間の箇所に導く排出用導風部が設けられている点を特徴とする。
In addition to the first feature configuration, the third feature configuration is
The heating means is provided at a location nearer to the ventilation direction than the humidity control body in the exhaust air passage, and a part of the sensible heat exchanger is lower in the ventilation direction than the humidity control body in the supply air passage. It is arranged to be located at a side location and the other part is located at a location closer to the ventilation direction than the heating means in the exhaust air passage, and after dehumidifying the supply air by the humidity control means, It is configured to cool with the sensible heat exchange means,
A discharge guide that guides a part of the supply air that has passed through the humidity control body and before passing through the sensible heat exchanger to a location between the sensible heat exchanger and the heating means in the exhaust air passage. It is characterized in that a wind part is provided.

即ち、調湿体を通過し且つ顕熱交換体を通過する前の供給用空気の一部が、排出用導風部を通じて排気風路における顕熱交換体と加熱手段との間の箇所に導かれながら、排出用空気が、顕熱交換体、加熱手段、調湿体を順次通過して通流し、供給用空気が、調湿体、顕熱交換体を順次通過して通流する。
つまり、加熱手段を加熱作用状態にすると、排出用空気は、顕熱交換体を通過するときにその顕熱交換体の保有熱を吸熱することにより加熱され、更に、加熱手段を通過することで加熱され、その排出用空気が調湿体を通過するときに調湿体から放湿され、供給用空気は、調湿体を通過することで除湿並びに加熱され、その供給用空気は顕熱交換体を通過することで冷却されるので、供給用空気を除湿する除湿運転を行うことができる。
That is, a part of the supply air that has passed through the humidity control body and before passing through the sensible heat exchanger is guided to a location between the sensible heat exchanger and the heating means in the exhaust air passage through the discharge wind guide section. While being discharged, the discharge air passes through the sensible heat exchanger, the heating means, and the humidity control body in order, and the supply air passes through the humidity control body and the sensible heat exchanger in order.
In other words, when the heating means is in the heating action state, the exhaust air is heated by absorbing the heat held by the sensible heat exchanger when passing through the sensible heat exchanger, and further passes through the heating means. When the exhaust air passes through the humidity control body, it is dehumidified from the humidity control body, and the supply air is dehumidified and heated by passing through the humidity control body, and the supply air is sensible heat exchanged. Since it cools by passing a body, the dehumidification driving | operation which dehumidifies supply air can be performed.

そして、調湿体を通過し且つ顕熱交換体を通過する前の高温の供給用空気の一部が、排気風路における顕熱交換体と加熱手段との間の箇所に導かれて排出用空気に混合されるので、調湿体を通過する前の排出用空気の大風量化及び低湿度化により、調湿体から排出用空気への放湿量がより多くなって、供給用空気を除湿する除湿性能を向上させることが可能となる。
従って、除湿運転が可能な空調装置において、空調対象空間の除湿性能の向上を図ることができるようになった。
Then, a part of the high-temperature supply air that has passed through the humidity control body and before passing through the sensible heat exchanger is led to a location between the sensible heat exchanger and the heating means in the exhaust air passage. Since it is mixed with the air, the amount of moisture released from the humidity control body to the discharge air is increased by increasing the air volume and reducing the humidity of the discharge air before passing through the humidity control body. It is possible to improve the dehumidifying performance for dehumidifying.
Therefore, in the air conditioner capable of dehumidifying operation, the dehumidifying performance of the air-conditioning target space can be improved.

第4特徴構成は、上記第1〜第3特徴構成のいずれかに加えて、
前記顕熱交換手段が、前記顕熱交換体における前記給気風路に位置させる部分及び前記排気風路に位置させる部分を回転に伴って変更させるように前記顕熱交換体を駆動回転する顕熱交換用駆動手段を備えて構成され、且つ、前記顕熱交換用駆動手段にて前記顕熱交換体を駆動回転させる顕熱交換作動状態と、前記顕熱交換用駆動手段による前記顕熱交換体の駆動回転を停止させる顕熱交換停止状態とに切り換え自在に構成されている点を特徴とする。
In addition to any of the first to third feature configurations described above, the fourth feature configuration is
The sensible heat that drives and rotates the sensible heat exchanger so that the sensible heat exchange means changes the portion located in the air supply air passage and the portion located in the exhaust air passage in the sensible heat exchanger with rotation. And a sensible heat exchange operation state in which the sensible heat exchange drive is driven and rotated by the sensible heat exchange drive means, and the sensible heat exchange body by the sensible heat exchange drive means. It is characterized in that it is configured to be switchable to a sensible heat exchange stop state in which the drive rotation is stopped.

即ち、顕熱交換手段を、顕熱交換用駆動手段にて顕熱交換体を駆動回転させる顕熱交換作動状態にて運転したり、顕熱交換用駆動手段による顕熱交換体の駆動回転を停止させる顕熱交換停止状態にて運転させたりすることができる。
つまり、調湿用駆動手段の作動を停止させて調湿体の駆動回転を停止し且つ加熱手段を加熱停止状態にした状態で、顕熱交換手段を顕熱交換作動状態にすると、供給用空気と排出用空気とを顕熱交換体において顕熱交換させるだけの状態で運転する顕熱交換運転が可能となり、又、調湿用駆動手段の作動を停止させて調湿体の駆動回転を停止し且つ加熱手段を加熱停止状態にした状態で、顕熱交換手段を顕熱交換停止状態にすると、例えば供給用空気が外気であり且つ排出用空気が空調対象空間内の空気である場合では、空調対象空間を空調することなく換気する通常換気運転が可能となる。
又、除湿運転が可能なように構成した場合に、調湿体を供給用空気の除湿に適した駆動回転速度にて回転駆動し且つ加熱手段を加熱作用状態にした状態で、顕熱交換手段を顕熱交換作動状態にすると、除湿運転を行うことができ、顕熱交換手段を顕熱交換停止状態にすると、低湿で高温の空気の供給が可能となる乾燥運転を行うことができる。尚、乾燥運転は、例えば、空調対象空間を乾燥させる用途に好適である。
従って、加湿運転又は除湿運転、及び、全熱・顕熱交換運転に加えて、供給用空気と排出用空気とを顕熱交換させるだけの顕熱交換運転と、空調対象空間を空調することなく換気する通常換気運転にも切り換えて運転することも可能となり、又、除湿運転が可能なように構成した場合には、更に、乾燥運転にも切り換えて運転することが可能となるので、使い勝手をより一層向上することができるようになった。
That is, the sensible heat exchange means is operated in a sensible heat exchange operation state in which the sensible heat exchange driving means is driven to rotate the sensible heat exchange driving means, or the sensible heat exchange driving means is rotated by the sensible heat exchange driving means. It can be operated in a sensible heat exchange stop state to be stopped.
That is, when the operation of the humidity control drive means is stopped, the drive rotation of the humidity control body is stopped, and the heating means is in the heating stop state, the sensible heat exchange means is brought into the sensible heat exchange operation state. Sensible heat exchange operation is possible, in which the sensible heat exchanger only exchanges sensible heat with the exhaust air, and the humidity control drive is stopped to stop the rotation of the humidity control body. When the sensible heat exchange means is in the sensible heat exchange stopped state with the heating means in the heating stopped state, for example, in the case where the supply air is outside air and the discharge air is air in the air-conditioning target space, A normal ventilation operation in which the air-conditioning target space is ventilated without air conditioning becomes possible.
Further, when the dehumidifying operation is possible, the sensible heat exchanging means is driven while the humidity control body is rotated at a driving rotational speed suitable for dehumidification of the supply air and the heating means is in a heating action state. When the sensible heat exchange operation state is set, the dehumidifying operation can be performed, and when the sensible heat exchange unit is set to the sensible heat exchange stopped state, the drying operation capable of supplying high-temperature air with low humidity can be performed. Note that the drying operation is suitable for use in drying the air-conditioning target space, for example.
Therefore, in addition to the humidifying or dehumidifying operation and the total heat / sensible heat exchanging operation, the sensible heat exchanging operation in which only the sensible heat exchange between the supply air and the exhaust air is performed, and the air conditioning target space is not air-conditioned. It is also possible to switch to normal ventilation operation that ventilates, and if it is configured so that dehumidification operation is possible, it can also be switched to dry operation, so it is easy to use. It has become possible to further improve.

Since the operation mode is provided, the operation mode can be switched by a simple operation.

ちなみに、加熱手段を給気風路における調湿体よりも通風方向上手側箇所に設けると、調湿運転として加湿運転が実行でき、加熱手段を排気風路における調湿体よりも通風方向上手側箇所に設けると、調湿運転として除湿運転を実行できる。

又、顕熱交換運転では、供給用空気と排出用空気とを顕熱交換させるだけの状態で運転することができる。
又、通常換気運転では、供給用空気と排出用空気との間で熱交換を行わせること無く、供給用空気を空調対象空間に供給すると共に、排出用空気を空調対象空間外に排出することができるので、例えば、供給用空気を外気とし、排出用空気を空調対象空間内の空気とすると、空調対象空間を空調することなく換気することができる。
従って、調湿運転モード、全熱・顕熱交換運転モード、顕熱交換運転モード並びに通常換気運転モードのうちの少なくとも調湿運転モード及び全熱・顕熱交換運転モードを、例えば、空調対象空間の空気の状況(例えば湿度や温度)に応じて選択して、簡単な操作にて実行させることができるので、使い勝手をより一層向上させることができるようになった。
By the way, if the heating means is provided at the upper side in the ventilation direction than the humidity control body in the supply air path, the humidification operation can be executed as the humidity control operation, and the heating means is located at the upper side in the ventilation direction than the humidity control body in the exhaust air path. If it provides, dehumidification operation can be performed as humidity control operation.
Further, in the total heat / sensible heat exchange operation mode, as described above, the operation can be performed to increase the enthalpy exchange efficiency between the supply air and the discharge air.
Further, in the sensible heat exchange operation, the operation can be performed in a state in which the supply air and the discharge air are only subjected to sensible heat exchange.
Further, in normal ventilation operation, supply air is supplied to the air-conditioning target space without causing heat exchange between the supply air and the discharge air, and the discharge air is discharged outside the air-conditioning target space. Therefore, for example, when the supply air is the outside air and the discharge air is the air in the air-conditioning target space, the air-conditioning target space can be ventilated without air conditioning.
Accordingly, at least the humidity adjustment operation mode and the total heat / sensible heat exchange operation mode among the humidity adjustment operation mode, the total heat / sensible heat exchange operation mode, the sensible heat exchange operation mode, and the normal ventilation operation mode are set to, for example, the air-conditioning target space. Since it can be selected according to the air condition (for example, humidity or temperature) and executed by a simple operation, the usability can be further improved.

To do.

即ち、空調対象空間の湿度を検出する空間内湿度検出手段及び外気の湿度を検出する外気湿度検出手段の検出情報、又は、空間内湿度検出手段、外気湿度検出手段、空調対象空間の温度を検出する空間内温度検出手段及び外気の温度を検出する外気温度検出手段夫々の検出情報に基づいて、空調対象空間の空気の状況や外気の状況を求めることができるので、その求めた空調対象空間の空気の状況や外気の状況に応じた運転モードを自動的に選択させて、実行させることが可能となる。   That is, the detection information of the humidity detection means in the space for detecting the humidity of the air-conditioning target space and the detection information of the outside air humidity detection means for detecting the humidity of the outside air, or the temperature detection in the space, the outdoor air humidity detection means, and the temperature of the air-conditioning target space are detected. Based on the detection information of each of the space temperature detection means and the outside air temperature detection means for detecting the temperature of the outside air, it is possible to obtain the air condition and the outside air condition of the air conditioning target space. It is possible to automatically select and execute an operation mode according to the air condition or the outside air condition.

例えば、空調対象空間の空気の状況や外気の状況により、空調対象空間を加湿するのが好ましいと判断されるときは、調湿運転としての加湿運転を実行させ、空調対象空間を除湿するのが好ましいときは、調湿運転としての除湿運転を実行させるようにすると、空調対象空間の湿度を好ましいものにすることが可能となる。   For example, when it is determined that it is preferable to humidify the air-conditioning target space according to the air condition of the air-conditioning target space or the outside air condition, the humidification operation as the humidity control operation is executed to dehumidify the air-conditioning target space. When preferable, when the dehumidifying operation as the humidity control operation is executed, the humidity of the air-conditioning target space can be made preferable.

It becomes possible to increase the enthalpy exchange efficiency of the battery and reduce the energy consumption related to heating and cooling.

又、運転モードとして顕熱交換運転モードを備えていて、例えば、供給用空気を外気とし、排出用空気を空調対象空間内の空気とする場合は、空調対象空間内の空気の状況が適温で且つ外気の状況が適湿であると判断されるとき等に、顕熱交換運転モードを実行させるようにすると、空調対象空間を換気しながら、空調対象空間の温度及び湿度を好ましいものにすることが可能となる。   Also, when the sensible heat exchange operation mode is provided as the operation mode, for example, when the supply air is outside air and the discharge air is air in the air-conditioning target space, the air condition in the air-conditioning target space is at an appropriate temperature. When the sensible heat exchange operation mode is executed when the outside air condition is determined to be appropriate humidity, the temperature and humidity of the air-conditioning target space should be made favorable while the air-conditioning target space is ventilated. Is possible.

又、運転モードとして通常換気運転モードを備えていて、例えば、供給用空気を外気とし、排出用空気を空調対象空間内の空気とする場合は、外気の状況が適温適湿であると判断されると、通常換気運転モードを実行させるようにすると、空調対象空間を換気しながら、その温度及び湿度を好ましいものにすることが可能となる。
従って、空調対象空間の空気の状況や外気の状況に応じた運転モードが自動的に選択されて実行されるので、空調装置をより一層適切に運転させることができるようになった。
Also, a normal ventilation operation mode is provided as an operation mode. For example, when the supply air is outside air and the discharge air is air inside the air-conditioning target space, it is determined that the outside air condition is appropriate temperature and humidity. Then, when the normal ventilation operation mode is executed, it is possible to make the temperature and humidity favorable while ventilating the air-conditioning target space.
Therefore, since the operation mode according to the air condition of the air-conditioning target space and the outside air condition is automatically selected and executed, the air conditioner can be operated more appropriately.

前記調湿用設定速度及び前記全熱交換用設定速度は、夫々予め設定して前記運転制御部11に記憶させてある。
以下、前記調湿用設定速度及び前記全熱交換用設定速度夫々の設定の仕方について説明を加える。
尚、前記調湿用設定速度については、詳細は後述の第9実施形態にて説明するが、調湿体6は、回転速度が1.3回/分のときに、調湿部Lの除湿性能が最大となるので、前記調湿用設定速度は、例えば1.3回/分に設定してある。
The humidity control setting speed and the total heat exchange setting speed are set in advance and stored in the operation control unit 11.
Hereinafter, description will be added on how to set the humidity control setting speed and the total heat exchange setting speed.
The humidity setting speed will be described in detail in a ninth embodiment to be described later. However, when the rotation speed is 1.3 times / minute, the humidity control body 6 performs dehumidification of the humidity control section L. Since the performance is maximized, the set speed for humidity control is set to 1.3 times / minute, for example.

図35中の実線は、空調対象室が冷房される夏期を想定して、調湿部Lの全熱交換性能を検証したものであり、前記加湿暖房用の加熱器8を加熱停止状態にし、且つ、前記給気風路2の方が高温多湿になる状態でその給気風路2及び前記排気風路4の夫々に通風させる状態で、調湿体7の回転速度を変更させて、各回転速度での調湿部Lの全熱交換性能をエンタルピーにて、回転速度が1.3回/分のときを100%として比較したものである。
又、図35中の破線は、空調対象室が暖房される冬期を想定して、調湿部Lの全熱交換性能を検証したものであり、前記加湿暖房用の加熱器8を加熱停止状態にし、且つ、前記排気風路4の方が高温多湿になる状態で前記給気風路2及び前記排気風路4の夫々に通風させる状態で、調湿体7の回転速度を変更させて、各回転速度での調湿部Lの全熱交換性能をエンタルピーにて、回転速度が1.3回/分のときを100%として比較したものである。
The solid line in FIG. 35 is the result of verifying the total heat exchange performance of the humidity control section L assuming the summer season when the air-conditioning target room is cooled, and the heater 8 for humidification heating is set in a heating stopped state. In addition, the rotational speed of the humidity control body 7 is changed in a state in which the air supply air path 2 is in a state where the air supply air path 2 and the exhaust air path 4 are ventilated in a state where the air supply air path 2 is hotter and humid. The total heat exchange performance of the humidity control section L at enthalpy is compared with 100% when the rotation speed is 1.3 times / minute.
Further, the broken line in FIG. 35 verifies the total heat exchange performance of the humidity control section L in the winter when the air-conditioning target room is heated, and the humidifier heating heater 8 is in a heating stopped state. In addition, the rotational speed of the humidity control body 7 is changed in the state where the exhaust air passage 4 is in a state of higher temperature and humidity and the air supply air passage 2 and the exhaust air passage 4 are ventilated. The total heat exchange performance of the humidity control section L at the rotation speed is compared with enthalpy, assuming that the rotation speed is 1.3 times / minute as 100%.

つまり、空調対象室が暖房される冬期等、排出用空気EAの方が供給用空気SAよりも高温多湿の状態となるときは、調湿部Lの全熱交換性能は、調湿体7の回転速度を前記調湿用設定速度である1.3回/分よりも高速にすると高くなり、2.8〜5.3回/分の範囲でより高くなり、4.7回/分のときに最高になることが分かる。
又、空調対象室が冷房される夏期等、供給用空気SAの方が排出用空気EAよりも高温多湿の状態となるときは、調湿部Lの全熱交換性能は、調湿体7の回転速度を前記調湿用設定速度である1.3回/分よりも高速にすると高くなり、4.0〜5.3回/分の範囲でより高くなり、4.7回/分のときに最高になることが分かる
That is, when the air-conditioning target room is heated, such as in the winter, when the exhaust air EA is in a higher temperature and humidity state than the supply air SA, the total heat exchange performance of the humidity control section L is that of the humidity control body 7. When the rotational speed is higher than 1.3 times / minute, which is the setting speed for humidity control, the rotational speed becomes higher. When the rotational speed is in the range of 2.8 to 5.3 times / minute, the speed becomes 4.7 times / minute. It turns out to be the best.
Further, when the supply air SA is in a higher temperature and humidity state than the discharge air EA, such as in summer when the air-conditioned room is cooled, the total heat exchange performance of the humidity control section L is that of the humidity control body 7. When the rotational speed is higher than the humidity control setting speed of 1.3 times / minute, the rotational speed becomes higher, and becomes higher in the range of 4.0 to 5.3 times / minute, and when the speed is 4.7 times / minute. To be the best

従って、空調対象室が暖房される冬期等、排出用空気EAの方が供給用空気SAよりも高温多湿の状態のときは、前記全熱交換用設定速度を、前記調湿用設定速度の2.2〜4.1倍に設定するのが好ましく、前記調湿用設定速度の3.6倍に設定するのが最も好ましい。
又、空調対象室が冷房される夏期等、供給用空気SAの方が排出用空気EAよりも高温多湿の状態のときは、前記全熱交換用設定速度を、前記調湿用設定速度の3.1〜4.1倍に設定するのが好ましく、前記調湿用設定速度の3.6倍に設定するのが最も好ましい。
Therefore, when the air-conditioning target room is heated, such as in the winter, when the exhaust air EA is hotter and humid than the supply air SA, the total heat exchange setting speed is set to 2 of the humidity adjustment setting speed. It is preferably set to 2 to 4.1 times, and most preferably set to 3.6 times the set speed for humidity control.
When the supply air SA is hotter and humid than the exhaust air EA, such as in summer when the air-conditioning target room is cooled, the total heat exchange setting speed is set to 3% of the humidity adjustment setting speed. It is preferable to set it to .1 to 4.1 times, and it is most preferable to set it to 3.6 times the set speed for humidity control.

以上のように、調湿体6の回転速度を調湿用設定速度よりも高くすることにより、調湿部Lの全熱交換性能を向上可能なことが分かる。   As mentioned above, it turns out that the total heat exchange performance of the humidity control part L can be improved by making the rotational speed of the humidity control body 6 higher than the setting speed for humidity control.

又、外気の湿度を検出する外気湿度検出手段としての外気湿度センサ19、及び、外気の温度を検出する外気温度検出手段としての外気温度センサ20を設けてある。
前記操作部12は、空調対象空間としての空調対象室に設けられるものであり、その操作部12には、空調対象室の湿度を検出する空間内湿度検出手段としての室内湿度センサ21、及び、空調対象室の温度を検出する空間内温度検出手段としての室内温度センサ22を設けてある。
Further, an outside air humidity sensor 19 as an outside air humidity detecting means for detecting the humidity of the outside air and an outside air temperature sensor 20 as an outside air temperature detecting means for detecting the temperature of the outside air are provided.
The operation unit 12 is provided in an air-conditioning target room as an air-conditioning target space, and the operation unit 12 includes an indoor humidity sensor 21 as a humidity detection unit in the space for detecting the humidity of the air-conditioning target room, and An indoor temperature sensor 22 is provided as space temperature detecting means for detecting the temperature of the air conditioning target room.

更に、前記操作部12には、図示を省略するが、上述のようにこの空調装置に備えさせてある複数の運転モードを択一的に選択して実行させる運転モード選択スイッチ、及び、外気湿度センサ19、外気温度センサ20、室内湿度センサ21及び室内温度センサ22夫々の検出情報に基づいて、前記複数の運転モードから運転モードを自動的に選択して実行するモード自動選択運転の開始及び停止を指令する自動運転スイッチを設けてある。   Furthermore, although not shown in the drawing, the operation unit 12 selectively selects and executes a plurality of operation modes provided in the air conditioner as described above, and the outside air humidity. Start and stop of mode automatic selection operation in which the operation mode is automatically selected and executed from the plurality of operation modes based on the detection information of the sensor 19, the outside air temperature sensor 20, the indoor humidity sensor 21 and the indoor temperature sensor 22. An automatic operation switch for commanding is provided.

次に、前記運転制御部11の制御動作について、説明する。
運転制御部11は、前記操作部12からの指令情報に基づいて、運転モード選択スイッチにて指令された運転モードを実行し、又、自動運転スイッチにてモード自動選択運転が指令されると、そのモード自動選択運転を実行するように構成してある。
Next, the control operation of the operation control unit 11 will be described.
The operation control unit 11 executes the operation mode instructed by the operation mode selection switch based on the instruction information from the operation unit 12, and when the mode automatic selection operation is instructed by the automatic operation switch, The mode automatic selection operation is executed.

以下、図4に基づいて、上記の各運転モード夫々についての前記運転制御部11の制御動作を説明する。
前記通常換気運転モードでは、前記給気送風機3及び前記排気送風機5夫々を作動させ、前記調湿用電動モータ7を停止させて前記調湿体6の回転を停止させ、前記加湿暖房用熱動弁16を閉弁して前記加湿暖房用の加熱器8を加熱停止状態にし、前記顕熱交換用電動モータ10を停止させて前記顕熱交換部Sを顕熱交換停止状態にする。
Hereinafter, based on FIG. 4, the control operation of the operation control unit 11 for each of the operation modes will be described.
In the normal ventilation operation mode, the air supply blower 3 and the exhaust blower 5 are operated, the humidity control electric motor 7 is stopped, the rotation of the humidity control body 6 is stopped, and the humidification heating thermal operation is performed. The valve 16 is closed to put the humidifying and heating heater 8 in a heating stop state, and the sensible heat exchange electric motor 10 is stopped to put the sensible heat exchange section S in a sensible heat exchange stop state.

前記加湿運転モードでは、前記給気送風機3及び前記排気送風機5夫々を作動させ、前記調湿体6を予め設定した調湿用設定速度にて回転駆動するように前記調湿用電動モータ7を作動させ、前記加湿暖房用熱動弁16を開弁して前記加湿暖房用の加熱器8を加熱作用状態にし、前記顕熱交換用電動モータ10を作動させて前記顕熱交換部Sを顕熱交換作動状態にする。   In the humidification operation mode, the air supply fan 3 and the exhaust fan 5 are operated, and the humidity control electric motor 7 is driven to rotate the humidity control body 6 at a preset humidity control speed. The humidifying / heating heater 16 is opened to bring the humidifying / heating heater 8 into a heating state, and the sensible heat exchanging electric motor 10 is activated to reveal the sensible heat exchanging portion S. Turn on heat exchange.

この加湿運転モードでは、図2を参照すると、排出用空気入口1eiから排気風路4に吸い込まれた排出用空気EAは、前記調湿用設定速度にて回転する調湿体6、回転する顕熱交換体9を順次通過して通流して、排出用空気出口1eoから例えば排気ダクトを通じて屋外に排出され、一方、供給用空気入口1siから前記給気風路2に吸い込まれた供給用空気SAは、回転する顕熱交換体9、加熱作用状態の加湿暖房用の加熱器8、前記調湿用設定速度にて回転する調湿体6を順次通過して通流して、供給用空気出口1soから例えば給気ダクトを通じて空調対象室に供給される。   In this humidification operation mode, referring to FIG. 2, the exhaust air EA sucked into the exhaust air passage 4 from the exhaust air inlet 1ei is the humidity control body 6 that rotates at the humidity control set speed, The supply air SA that passes through the heat exchanger 9 in order, is discharged from the discharge air outlet 1eo to the outside through, for example, an exhaust duct, and is supplied to the supply air passage 2 from the supply air inlet 1si. The sensible heat exchanger 9 that rotates, the heater 8 for heating and humidifying heating, and the humidity control body 6 that rotates at the set speed for humidity control are sequentially passed through and supplied from the supply air outlet 1so. For example, the air-conditioning target room is supplied through an air supply duct.

そして、排出用空気EAは、前記調湿用設定速度にて回転する調湿体6を通過するときに、その排出用空気EA中の水蒸気が調湿体6に吸収されると共に凝縮熱により加熱され、その加熱並びに除湿された排出用空気EAが顕熱交換体9を通過するときに、その保有熱が顕熱交換体9に与えられて顕熱交換体9が加熱され、一方、供給用空気SAは、顕熱交換体9を通過することで、顕熱交換体9が排出用空気EAから得た熱により加熱され、更に、前記加湿暖房用の加熱器8を通過することで加熱され、そのように加熱された供給用空気SAが前記調湿用設定速度にて回転する調湿体6を通過するときに調湿体6から放湿されて加湿され、そのように加湿並びに加熱された供給用空気SAが空調対象室に供給される。   When the exhaust air EA passes through the humidity control body 6 that rotates at the humidity control speed, the water vapor in the exhaust air EA is absorbed by the humidity control body 6 and heated by condensation heat. When the exhaust air EA that has been heated and dehumidified passes through the sensible heat exchanger 9, the retained heat is given to the sensible heat exchanger 9, and the sensible heat exchanger 9 is heated. The air SA passes through the sensible heat exchanger 9 so that the sensible heat exchanger 9 is heated by the heat obtained from the discharge air EA, and is further heated by passing through the humidifier heating heater 8. When the supply air SA thus heated passes through the humidity control body 6 rotating at the humidity control setting speed, it is dehumidified from the humidity control body 6 and is humidified and heated as such. Supply air SA is supplied to the air-conditioning target room.

つまり、この加湿運転モードでは、空調対象室に供給される供給用空気SAを無給水にて加湿すると共に加熱して空調対象室に供給することが可能となり、各空調対象室を加湿並びに暖房することができる。   That is, in this humidification operation mode, the supply air SA supplied to the air-conditioning target room can be humidified with non-supply water and heated to be supplied to the air-conditioning target room, and each air-conditioning target room is humidified and heated. be able to.

図4に示すように、前記全熱・顕熱交換運転モードでは、前記給気送風機3及び前記排気送風機5夫々を作動させ、前記調湿体6を前記調湿用設定速度よりも高速の全熱交換用設定速度にて回転駆動するように前記調湿用電動モータ7を作動させ、前記加湿暖房用熱動弁16を閉弁して前記加湿暖房用の加熱器8を加熱停止状態にし、前記顕熱交換用電動モータ10を作動させて前記顕熱交換部Sを顕熱交換作動状態にする。   As shown in FIG. 4, in the total heat / sensible heat exchange operation mode, the air supply blower 3 and the exhaust blower 5 are operated, and the humidity control body 6 is operated at a speed higher than the set speed for humidity control. The humidity control electric motor 7 is operated so as to be rotationally driven at a heat exchange setting speed, the humidification heating thermal valve 16 is closed, and the humidification heating heater 8 is stopped. The sensible heat exchange electric motor 10 is operated to bring the sensible heat exchange section S into a sensible heat exchange operation state.

この全熱・顕熱交換運転モードでは、図2を参照すると、排出用空気EAは、前記全熱交換用設定速度にて回転する調湿体6、回転する顕熱交換体9を順次通過して通流し、一方、供給用空気SAは、回転する顕熱交換体9、加熱停止状態の加湿暖房用の加熱器8、前記全熱交換用設定速度にて回転する調湿体6を順次通過して通流する。   In this total heat / sensible heat exchange operation mode, referring to FIG. 2, the exhaust air EA sequentially passes through the humidity control body 6 rotating at the set speed for total heat exchange and the rotating sensible heat exchange body 9. On the other hand, the supply air SA sequentially passes through the rotating sensible heat exchanger 9, the humidifying and heating heater 8 in a heating stopped state, and the humidity control body 6 rotating at the set speed for total heat exchange. Then flow through.

そして、調湿体6においては、供給用空気SAと排出用空気EAとの間で全熱交換量をより多くする状態で全熱交換させることができ、顕熱交換体9においては、供給用空気SAと排出用空気EAとの間で顕熱交換させることができるので、エンタルピー交換効率を増大することができる。   In the humidity control body 6, total heat exchange can be performed between the supply air SA and the discharge air EA so that the total heat exchange amount is increased. In the sensible heat exchanger 9, the supply air SA Since sensible heat can be exchanged between the air SA and the discharge air EA, the enthalpy exchange efficiency can be increased.

冬期等、この空調装置とは別の空調装置により空調対象室が暖房されているときや、夏期等、この空調装置とは別の空調装置により空調対象室が冷房されているときに、この空調装置を全熱・顕熱交換運転モードにて運転させると、暖房や冷房に係わる消費エネルギを削減することができる。   This air conditioning target room is heated by an air conditioner different from this air conditioner in winter, etc., or when the air conditioning target room is cooled by an air conditioner different from this air conditioner in summer, etc. When the apparatus is operated in the total heat / sensible heat exchange operation mode, energy consumption related to heating and cooling can be reduced.

図4に示すように、前記暖房運転モードでは、前記給気送風機3及び前記排気送風機5夫々を作動させ、前記調湿体6を停止させ、前記加湿暖房用熱動弁16を開弁して前記加湿暖房用の加熱器8を加熱作用状態にし、前記顕熱交換用電動モータ10を作動させて前記顕熱交換部Sを顕熱交換作動状態にする。   As shown in FIG. 4, in the heating operation mode, the air supply blower 3 and the exhaust blower 5 are operated, the humidity control body 6 is stopped, and the humidification heating thermal valve 16 is opened. The humidifying / heating heater 8 is put into a heating action state, the sensible heat exchange electric motor 10 is operated, and the sensible heat exchange section S is put into a sensible heat exchange operation state.

この暖房運転モードでは、図2を参照すると、前記供給用空気入口1siから前記給気風路2に吸い込まれた供給用空気SAは、停止中の顕熱交換体9を顕熱交換されること無く通過し、前記加湿暖房用の加熱器8にて加熱され、停止中の調湿体6を全熱交換されること無く通過して、前記供給用空気出口1soから例えば給気ダクトを通じて空調対象室に供給され、前記排出用空気入口1eiから前記排気風路4に吸い込まれた排出用空気EAは、停止中の調湿体6及び停止中の顕熱交換体9を熱交換されること無く通過して、前記排出用空気出口1eoから例えば排気ダクトを通じて屋外に排出される。   In this heating operation mode, referring to FIG. 2, the supply air SA sucked into the supply air passage 2 from the supply air inlet 1si is not subjected to sensible heat exchange with the sensible heat exchanger 9 being stopped. Passing through the humidifying body 6 that is heated by the humidifying and heating heater 8 and passing through the stopped humidity control body 6 without being subjected to total heat exchange, the air-conditioning target room passes through the supply air outlet 1so, for example, through an air supply duct. The exhaust air EA sucked into the exhaust air passage 4 from the exhaust air inlet 1ei passes through the stopped humidity control unit 6 and the stopped sensible heat exchanger 9 without heat exchange. Then, the air is discharged from the exhaust air outlet 1eo to the outside through an exhaust duct, for example.

つまり、空調装置をこの暖房運転モードにて運転すると、供給用空気SAを加湿暖房用の加熱器8にて加熱して、空調対象室に供給することができるので、空調対象室を暖房することができる。   That is, when the air conditioner is operated in this heating operation mode, the supply air SA can be heated by the humidifying and heating heater 8 and supplied to the air-conditioning target room, so that the air-conditioning target room is heated.

The humidifying / heating heater 16 is closed, the humidifying / heating heater 8 is stopped, and the sensible heat exchanging electric motor 10 is operated to sensible heat the sensible heat exchanging part S. Set to exchange operation.

この顕熱交換運転モードでは、図2を参照すると、排出用空気EAは、停止中の調湿体6、回転する顕熱交換体9を順次通過して通流し、一方、供給用空気SAは、回転する顕熱交換体9、加熱停止状態の加湿暖房用の加熱器8、停止中の調湿体6を順次通過して通流するので、顕熱交換体9において、供給用空気SAと排出用空気EAとを顕熱交換させることができる。   In this sensible heat exchange operation mode, referring to FIG. 2, the discharge air EA passes through the stopped humidity control body 6 and the rotating sensible heat exchange body 9 sequentially, while the supply air SA is Since the rotating sensible heat exchanger 9, the humidifying and heating heater 8 in the heating stopped state, and the humidity control body 6 in the stopped state are sequentially passed through, the supply air SA and the sensible heat exchanger 9 The sensible heat can be exchanged with the discharge air EA.

つまり、空調装置をこの顕熱交換運転モードにて運転すると、供給用空気SAの方が排出用空気EAよりも高温のときは、供給用空気SAを冷却して空調対象室に供給することができ、供給用空気SAの方が排出用空気EAよりも低温のときは、供給用空気SAを加熱して空調対象室に供給することができる。   That is, when the air conditioner is operated in this sensible heat exchange operation mode, when the supply air SA is hotter than the discharge air EA, the supply air SA can be cooled and supplied to the air-conditioning target room. When the supply air SA is cooler than the discharge air EA, the supply air SA can be heated and supplied to the air-conditioning target room.

この除湿運転モードでは、図15を参照すると、排出用空気入口1eiから排気風路4に吸い込まれた排出用空気EAは、回転する顕熱交換体9、加熱作用状態の除湿用の加熱器24、前記調湿用設定速度にて回転する調湿体6を順次通過して通流して、排出用空気出口1eoから例えば排気ダクトを通じて屋外に排出され、一方、供給用空気入口1siから前記給気風路2に吸い込まれた供給用空気SAは、前記調湿用設定速度にて回転する調湿体6、回転する顕熱交換体9を順次通過して通流して、供給用空気出口1soから例えば給気ダクトを通じて空調対象室に供給される。   In this dehumidifying operation mode, referring to FIG. 15, the exhaust air EA sucked into the exhaust air passage 4 from the exhaust air inlet 1ei is rotated by the sensible heat exchanger 9 and the heater 24 for dehumidification in the heating action state. Then, the air passes through the humidity control body 6 that rotates at the set speed for humidity control in order, and is discharged from the discharge air outlet 1eo to the outside through, for example, an exhaust duct, while being supplied from the supply air inlet 1si The supply air SA sucked into the passage 2 sequentially passes through the humidity control body 6 and the sensible heat exchanger 9 that rotate at the humidity control setting speed, and flows from the supply air outlet 1so, for example. It is supplied to the air-conditioned room through the air supply duct.

そして、排出用空気EAは、顕熱交換体9を通過するときに、その顕熱交換体9が供給用空気SAから得た熱を吸熱することにより加熱され、更に、除湿用の加熱器24を通過することで加熱され、そのように加熱された排出用空気EAが調湿体6を通過するときに調湿体6から放湿されて加湿され、一方、供給用空気SAは、調湿体6を通過するときに、その供給用空気SA中の水蒸気が調湿体6に吸収されて除湿されると共に凝縮熱により加熱され、そのように除湿並びに加熱された供給用空気SAが顕熱交換体9を通過するときに、その保有熱が顕熱交換体9に与えられて冷却され、そのように除湿並びに冷却された供給用空気SAが空調対象室に供給されるので、空調対象室を除湿することができる。   Then, when the exhaust air EA passes through the sensible heat exchanger 9, the sensible heat exchanger 9 is heated by absorbing heat obtained from the supply air SA, and further, a dehumidifying heater 24. When the exhaust air EA thus heated passes through the humidity control body 6, it is dehumidified from the humidity control body 6 and humidified, while the supply air SA is controlled by the humidity control body 6. When passing through the body 6, water vapor in the supply air SA is absorbed by the humidity control body 6 and dehumidified and heated by condensation heat, and the supply air SA thus dehumidified and heated is sensible heat. When passing through the exchanger 9, the retained heat is given to the sensible heat exchanger 9 to be cooled, and the supply air SA thus dehumidified and cooled is supplied to the air-conditioning target room. Can be dehumidified.

図16に示すように、前記全熱・顕熱交換運転モードでは、前記給気送風機3及び前記排気送風機5夫々を作動させ、前記調湿体6を前記調湿用設定速度よりも高速の全熱交換用設定速度にて回転駆動するように前記調湿用電動モータ7を作動させ、前記除湿用熱動弁26を閉弁して前記除湿用の加熱器24を加熱停止状態にし、前記顕熱交換用電動モータ10を作動させて前記顕熱交換部Sを顕熱交換作動状態にする。   As shown in FIG. 16, in the total heat / sensible heat exchange operation mode, the air supply blower 3 and the exhaust blower 5 are operated, and the humidity control body 6 is operated at a higher speed than the set speed for humidity control. The humidity control electric motor 7 is operated so as to be rotationally driven at a heat exchange set speed, the dehumidification thermal valve 26 is closed, and the dehumidification heater 24 is brought into a heating stop state, so that The heat exchange electric motor 10 is operated to bring the sensible heat exchange section S into a sensible heat exchange operation state.

この全熱・顕熱交換運転モードでは、図15を参照すると、排出用空気EAは、回転する顕熱交換体9、加熱停止状態の除湿用の加熱器24、前記全熱交換用設定速度にて回転する調湿体6を順次通過して通流し、一方、供給用空気SAは、前記全熱交換用設定速度にて回転する調湿体6、回転する顕熱交換体9を順次通過して通流する。   In this total heat / sensible heat exchange operation mode, referring to FIG. 15, the discharge air EA has a rotating sensible heat exchanger 9, a heating dehumidifying heater 24, and the total heat exchange set speed. The rotating air conditioner 6 sequentially passes through and flows, while the supply air SA sequentially passes through the humidity adjusting body 6 rotating at the total heat exchange setting speed and the rotating sensible heat exchanger 9. To flow through.

そして、調湿体6においては、供給用空気SAと排出用空気EAとの間で全熱交換量をより多くする状態で全熱交換させることができ、顕熱交換体9においては、供給用空気SAと排出用空気EAとの間で顕熱交換させることができるので、エンタルピー交換効率を増大することができる。   In the humidity control body 6, total heat exchange can be performed between the supply air SA and the discharge air EA so that the total heat exchange amount is increased. In the sensible heat exchanger 9, the supply air SA Since sensible heat can be exchanged between the air SA and the discharge air EA, the enthalpy exchange efficiency can be increased.

冬期等、この空調装置とは別の空調装置により空調対象室が暖房されているときや、夏期等、この空調装置とは別の空調装置により空調対象室が冷房されているときに、この空調装置を全熱・顕熱交換運転モードにて運転させると、暖房や冷房に係わる消費エネルギを削減することができる。   This air conditioning target room is heated by an air conditioner different from this air conditioner in winter, etc., or when the air conditioning target room is cooled by an air conditioner different from this air conditioner in summer, etc. When the apparatus is operated in the total heat / sensible heat exchange operation mode, energy consumption related to heating and cooling can be reduced.

前記顕熱交換運転モードでは、前記給気送風機3及び前記排気送風機5夫々を作動させ、前記調湿用電動モータ7を停止させて前記調湿体6の回転を停止させ、前記加湿暖房用熱動弁16を閉弁して前記加湿暖房用の加熱器8を加熱停止状態にし、前記顕熱交換用電動モータ10を作動させて前記顕熱交換部Sを顕熱交換作動状態にする。   In the sensible heat exchange operation mode, the air supply blower 3 and the exhaust blower 5 are operated, the humidity control electric motor 7 is stopped, the rotation of the humidity control body 6 is stopped, and the humidifying heating heat The valve 16 is closed to put the humidifying and heating heater 8 in a heating stop state, and the sensible heat exchange electric motor 10 is operated to bring the sensible heat exchange section S into a sensible heat exchange operation state.

この顕熱交換運転モードでは、図15を参照すると、排出用空気EAは、回転する顕熱交換体9、加熱停止状態の除湿用の加熱器24、停止中の調湿体6を順次通過して通流し、一方、供給用空気SAは、停止中の調湿体6、回転する顕熱交換体9を順次通過して通流するので、顕熱交換体9において、供給用空気SAと排出用空気EAとを顕熱交換させることができる。   In this sensible heat exchange operation mode, referring to FIG. 15, the exhaust air EA sequentially passes through the rotating sensible heat exchanger 9, the dehumidifying heater 24 in the heating stopped state, and the stopped humidity control body 6. On the other hand, the supply air SA passes through the stopped humidity control body 6 and the rotating sensible heat exchanger 9 in order, so that the supply air SA and the exhaust air are discharged from the sensible heat exchanger 9. The sensible heat can be exchanged with the working air EA.

つまり、空調装置をこの顕熱交換運転モードにて運転すると、供給用空気SAの方が排出用空気EAよりも高温のときは、供給用空気SAを冷却して空調対象室に供給することができ、供給用空気SAの方が排出用空気EAよりも低温のときは、供給用空気SAを加熱して空調対象室に供給することができる。   That is, when the air conditioner is operated in this sensible heat exchange operation mode, when the supply air SA is hotter than the discharge air EA, the supply air SA can be cooled and supplied to the air-conditioning target room. When the supply air SA is cooler than the discharge air EA, the supply air SA can be heated and supplied to the air-conditioning target room.

[Thirteenth embodiment]
Hereinafter, the thirteenth embodiment will be described. In the thirteenth embodiment, as shown in FIG. 22, the supply air SA before passing through the humidity control body 6 and before passing through the sensible heat exchange body 9 is shown.

Since the air is guided to the location between the heater 24 and mixed with the exhaust air EA, in the dehumidifying operation mode, the humidity is adjusted by increasing the air volume and reducing the humidity of the exhaust air EA before passing through the humidity control body 6.
