特開２００２−２７６９９６号公報JP 2002-276996 A

上記特許文献１に開示の技術では、例えば、エンジンの起動時等で、熱交換器へ導かれる湯水をエンジンの排熱にて十分に昇温できない場合等には、第１排気領域でのデシカントロータの再生を適切に行うことができないという課題があった。   In the technique disclosed in Patent Document 1 described above, for example, when the temperature of hot water introduced to the heat exchanger cannot be sufficiently increased by exhaust heat of the engine when the engine is started, the desiccant in the first exhaust region is used. There was a problem that the rotor could not be properly regenerated.

本発明は、上述の課題に鑑みてなされたものであり、その目的は、ＧＨＰとデシカント装置とを備えたものにおいて、ガスエンジンの立ち上がり時であっても、デシカントロータの再生を適切に行い、デシカント装置を介して室内空間へ供給される空調用空気の湿度を十分に下げることができる空調システムを提供することにある。   The present invention has been made in view of the above-mentioned problems, and its purpose is to provide a GHP and a desiccant device, and appropriately regenerate the desiccant rotor even when the gas engine starts up. An object of the present invention is to provide an air conditioning system that can sufficiently reduce the humidity of air-conditioning air supplied to an indoor space via a desiccant device.

上記目的を達成するための本発明の空調システムは、

室外空間から取り込んだ空気を室内空間へ供給する給気通路と、室内空間から取り出した空気を室外空間へ排気する排気通路と、前記給気通路に配置される第１給気領域と前記排気通路に配置される第１排気領域との間で通気性吸湿体から成るデシカントロータを回転駆動させて前記第１給気領域及び前記第１排気領域を通過する空気の除湿及び加湿を行う第１ロータ部と、前記給気通路の前記第１給気領域よりも下流側に配置される第２給気領域と前記排気通路における前記第１排気領域よりも上流側に配置される第２排気領域との間で通気性体からなる顕熱ロータを回転駆動させて前記第２給気領域を通過する空気と前記第２排気領域を通過する空気とを熱交換する第２ロータ部とを有するデシカント装置とを備え、
前記エンジンのエンジン冷却水循環路を通流するエンジン冷却水と前記排気通路を通流する空気とを熱交換する第１熱交換器を、前記排気通路の前記第１排気領域と前記第２排気領域との間に備えた空調システムであって、その特徴構成は、
前記冷房運転時において前記冷媒循環回路で前記蒸発器と前記圧縮機との間を通流する冷媒と前記給気通路を通流する空気とを熱交換する第２熱交換器を、前記給気通路を通流する空気の流れ方向で前記第１給気領域の上流側に備え、
前記冷房運転時において前記冷媒循環回路で前記圧縮機と前記凝縮器との間を通流する冷媒と前記排気通路を通流する空気とを熱交換する第３熱交換器を、前記排気通路で前記第１排気領域と前記第１熱交換器との間に備える点にある。 In order to achieve the above object, the air conditioning system of the present invention comprises:
A compressor driven by the engine to compress the refrigerant, a condenser that condenses the refrigerant compressed by the compressor, an expansion valve that expands the refrigerant condensed by the condenser, and an expansion valve that expands the refrigerant An evaporator that evaporates the refrigerant; and a refrigerant circulation circuit that circulates the refrigerant in the order described in the compressor, the condenser, the expansion valve, and the evaporator, and passes the evaporator during cooling operation. An engine-driven heat pump device that supplies air-conditioning air heat-exchanged with the refrigerant to the indoor space and supplies air-conditioning air heat-exchanged with the refrigerant flowing through the condenser during heating operation to the indoor space;
An air supply passage for supplying air taken from the outdoor space to the indoor space, an exhaust passage for exhausting air taken from the indoor space to the outdoor space, a first air supply region disposed in the air supply passage, and the exhaust passage A first rotor for dehumidifying and humidifying air passing through the first air supply region and the first exhaust region by rotating a desiccant rotor made of a breathable moisture absorber between the first exhaust region and the first exhaust region. A second air supply region disposed downstream of the first air supply region of the air supply passage, and a second exhaust region disposed upstream of the first exhaust region of the exhaust passage. A desiccant device having a second rotor portion that rotates and drives a sensible heat rotor made of a gas-permeable member between the air and passes through the second air supply region and air that passes through the second exhaust region. And
A first heat exchanger for exchanging heat between the engine coolant flowing through the engine coolant circulation path of the engine and the air flowing through the exhaust passage; and the first exhaust region and the second exhaust region of the exhaust passage. The air conditioning system provided between
A second heat exchanger for exchanging heat between the refrigerant flowing between the evaporator and the compressor and the air flowing through the supply passage in the refrigerant circulation circuit during the cooling operation; Provided upstream of the first air supply region in the flow direction of the air flowing through the passage ,
A third heat exchanger for exchanging heat between the refrigerant flowing between the compressor and the condenser and the air flowing through the exhaust passage in the refrigerant circulation circuit during the cooling operation; It exists in the point provided between a said 1st exhaust area and a said 1st heat exchanger .

上記特徴構成によれば、冷房運転時において冷媒循環路で蒸発器にて室内空間へ供給される空調用空気と熱交換した後の冷媒で、まだ冷熱を保有してる冷媒を、圧縮機に導かれる前に、第２熱交換器にて給気通路で第１給気領域へ導かれる前の空気と熱交換することができ、冷凍サイクルで余った冷熱をデシカント装置側で空調用空気を冷却する形態で、有効に利用できる。
しかも、当該構成にあっては、第１給気通路の第１給気領域を通過する前の空気を冷却するから、当該第１給気領域のデシカントロータに、比較的低温の空気を導くことができ、当該デシカントロータによる除湿性能を向上させることができる。 According to the above characteristic configuration, during the cooling operation, the refrigerant that has been heat-exchanged with the air-conditioning air supplied to the indoor space by the evaporator in the refrigerant circulation path and that still retains the cold heat is led to the compressor. Before being turned on, the second heat exchanger can exchange heat with the air before being led to the first air supply region in the air supply passage, and the cooling air remaining in the refrigeration cycle is cooled on the desiccant device side. Can be used effectively.
In addition, in this configuration, the air before passing through the first air supply region of the first air supply passage is cooled, so that relatively low temperature air is guided to the desiccant rotor in the first air supply region. And the dehumidifying performance of the desiccant rotor can be improved.

更に、上記特徴構成によれば、排気通路において、第１排気領域と第２排気領域の間に、エンジン冷却水と排気通路を通流する空気とを熱交換する第１熱交換器に加え、冷房運転時に冷媒循環路で圧縮機と凝縮器との間を通流する冷媒と排気通路を通流する空気とを熱交換する第３熱交換器を備えるから、第１排気領域を通過するデシカントロータを、第１熱交換器に加え、第３熱交換器によっても加熱することができる。これにより、エンジンの起動時等で、第１熱交換器により第１排気領域を通流する空気が十分に昇温できない場合であっても、第３熱交換器により冷媒と熱交換する形態で、十分に昇温できる。
特に、第３熱交換器を通流する冷媒は、圧縮機にて圧縮され十分に昇温した後で凝縮器に導かれる前の冷媒であるから、圧縮機の圧縮仕事によっては、エンジン冷却水よりも高い温度とすることができる。このため、上記特徴構成では、第３熱交換器を、第１排気通路において、第１排気領域と前記第１熱交換器との間、即ち、第１熱交換器の下流側へ設けることで、第１熱交換器の上流側へ設ける場合よりも、より一層、第１排気領域へ導かれる空気を昇温させる効果を発揮し得る。これにより、例えば、外気の湿度が高いときで、デシカントロータが多くの湿分を吸湿している場合であっても、当該デシカントロータを第１排気領域にて良好に再生でき、除湿性能を向上できる。 Further, according to the above characteristic configuration, in the exhaust passage, in addition to the first heat exchanger that exchanges heat between the engine coolant and the air flowing through the exhaust passage between the first exhaust region and the second exhaust region, A desiccant that passes through the first exhaust region is provided with a third heat exchanger that exchanges heat between the refrigerant flowing between the compressor and the condenser in the refrigerant circulation path and the air flowing through the exhaust passage during the cooling operation. The rotor can be heated by a third heat exchanger in addition to the first heat exchanger. Thereby, even when the air flowing through the first exhaust region cannot be sufficiently heated by the first heat exchanger at the time of starting the engine, the heat exchange with the refrigerant is performed by the third heat exchanger. The temperature can be raised sufficiently.
In particular, the refrigerant flowing through the third heat exchanger is a refrigerant that has been compressed by the compressor and sufficiently heated, and before being led to the condenser. Higher temperature. For this reason, in the above-described characteristic configuration, the third heat exchanger is provided in the first exhaust passage between the first exhaust region and the first heat exchanger, that is, downstream of the first heat exchanger. The effect of raising the temperature of the air guided to the first exhaust region can be further improved as compared with the case where it is provided on the upstream side of the first heat exchanger. Thereby, for example, even when the humidity of the outside air is high and the desiccant rotor absorbs a lot of moisture, the desiccant rotor can be regenerated well in the first exhaust region, and the dehumidifying performance is improved. it can.

本発明の空調システムの更なる特徴構成は、
前記圧縮機による圧縮仕事を、設定される除湿設定値に基づいて制御する制御手段が設けられている点にある。 Further features of the air conditioning system of the present invention are as follows:
A control means for controlling the compression work by the compressor based on a set dehumidification set value is provided.

上記特徴構成によれば、圧縮機による圧縮仕事を、設定される除湿設定値に基づいて制御する制御手段を備えているから、例えば、除湿設定値として『除湿量：低』に設定されている場合、圧縮機による圧縮仕事を高め、圧縮機から出る冷媒を昇温することで、第２熱交換器で当該冷媒と熱交換する空気を昇温し、当該昇温した空気により、第１排気領域を通過するデシカントロータを十分に再生する形態で、給気通路から供給される空調用空気の湿度を下げることができる。当該システムによれば、ＧＨＰの室内機としての蒸発器での冷房能力を上げ過ぎることなく、湿度を良好に低下させることができるから、特に、空調用空気の温度を下げ過ぎず、湿度を下げる場合に、有効となる。
尚、通常のエアコンにおいて、空調用空気の温度を下げず湿度を下げる場合、室内機内において、蒸発器にて室内空気を冷却して除湿した後に再度加熱する再熱除湿運転が実行されており、当該加熱は電気ヒータ等で実行されるため、非常に効率が悪くなる。
上記特徴構成によれば、このような加熱を行うことなく、空調用空気の温度を下げ過ぎずに、湿度を下げることができるから、通常のエアコンにおいて再熱除湿運転を行う場合に比べて、ＣＯＰの向上が期待できる。
逆に、除湿設定値として『除湿量：高』に設定されている場合、圧縮機による圧縮仕事を低下させ、圧縮機から出る冷媒を降温することで、第２熱交換器で当該冷媒と熱交換する空気を降温し、当該降温した空気により、第１排気領域を通過するデシカントロータを再生する形態で、給気通路から供給される空調用空気の除湿量を低下できる。 According to the above characteristic configuration, since the control means for controlling the compression work by the compressor based on the set dehumidification set value is provided, for example, “dehumidification amount: low” is set as the dehumidification set value. In this case, the compression work by the compressor is enhanced, and the temperature of the air that exchanges heat with the refrigerant is raised by the second heat exchanger by raising the temperature of the refrigerant that comes out of the compressor. The humidity of the air-conditioning air supplied from the air supply passage can be lowered in a form in which the desiccant rotor passing through the region is sufficiently regenerated. According to the system, since the humidity can be satisfactorily reduced without excessively increasing the cooling capacity of the evaporator as the GHP indoor unit, in particular, the temperature of the air-conditioning air is not excessively decreased and the humidity is decreased. In case, it becomes effective.
In a normal air conditioner, when the humidity is lowered without lowering the temperature of the air-conditioning air, a reheat dehumidification operation is performed in the indoor unit in which the indoor air is cooled and dehumidified with an evaporator and then heated again. Since the heating is performed by an electric heater or the like, the efficiency is very poor.
According to the above characteristic configuration, the humidity can be lowered without reducing the temperature of the air-conditioning air without performing such heating, compared with the case of performing the reheat dehumidifying operation in a normal air conditioner, Improvement of COP can be expected.
Conversely, when “dehumidification amount: high” is set as the dehumidification setting value, the compression work by the compressor is reduced, and the temperature of the refrigerant coming out of the compressor is lowered, so that the second heat exchanger and the refrigerant are heated. The dehumidifying amount of the air-conditioning air supplied from the air supply passage can be reduced in such a form that the temperature of the air to be exchanged is lowered and the desiccant rotor passing through the first exhaust region is regenerated by the lowered air.

本発明の空調システムの更なる特徴構成は、
前記制御手段は、前記圧縮機による圧縮仕事を、前記第３熱交換器への冷媒の流入温度が、前記第１熱交換器へ流入するエンジン冷却水の最高温度よりも高くなるように制御する点にある。 Further features of the air conditioning system of the present invention are as follows:
The control means controls the compression work by the compressor so that the inflow temperature of the refrigerant to the third heat exchanger is higher than the maximum temperature of the engine coolant flowing into the first heat exchanger. In the point.

上記特徴構成によれば、制御手段は、圧縮機による圧縮仕事を、第３熱交換器への冷媒の流入温度が、第１熱交換器へ流入するエンジン冷却水の最高温度よりも高くなるように制御するから、排気通路において、第１熱交換器の下流側に設けられる第３熱交換器にて、排気通路で第１熱交換器を通過した後の空気を更に昇温して、第１排気領域でデシカントロータの再生を良好に実行できる。 According to the above characteristic configuration, the control means performs the compression work by the compressor so that the refrigerant inflow temperature to the third heat exchanger is higher than the maximum temperature of the engine coolant flowing into the first heat exchanger. In the exhaust passage, in the third heat exchanger provided downstream of the first heat exchanger, the temperature of the air after passing through the first heat exchanger in the exhaust passage is further raised, The regeneration of the desiccant rotor can be satisfactorily performed in one exhaust region.

更に、ＧＨＰは、四方弁２６を図２に示す状態（図１に示す状態から９０度回転した状態）に切り替えることにより、膨張弁２４で膨張された冷媒が、蒸発器Ｊとしての室外熱交換器２３ａで室外空間ＯＳの空気と熱交換する形態で蒸発し、圧縮機２１で圧縮された冷媒が、凝縮器Ｇとしての室内熱交換器２５ａで室内空間ＩＳの空気と熱交換する形態で凝縮し、熱交換した後の室内の空気を比較的高温の空調用空気ＳＡとして室内空間ＩＳへ導く、所謂、暖房運転を実行する。 Thereby, the said GHP is the form which the refrigerant | coolant compressed with the compressor 21 heat-exchanges with outdoor air with the outdoor heat exchanger 23a as the condenser G by switching the four-way valve 26 to the state shown in FIG. The refrigerant condensed by the expansion valve 24 and expanded by the expansion valve 24 evaporates in a form in which heat is exchanged with the indoor air in the indoor heat exchanger 25a as the evaporator J, and the indoor air after the heat exchange is relatively low temperature and low humidity. A so-called cooling operation is performed in which the air-conditioning air SA is led to the indoor space IS.
Further, the GHP switches the four-way valve 26 to the state shown in FIG. 2 (the state rotated 90 degrees from the state shown in FIG. 1), so that the refrigerant expanded by the expansion valve 24 exchanges outdoor heat as the evaporator J. The refrigerant evaporated in the form of heat exchange with the air in the outdoor space OS in the condenser 23a and condensed in the form of heat exchange with the air in the indoor space IS in the indoor heat exchanger 25a as the condenser G Then, a so-called heating operation is performed in which the indoor air after the heat exchange is led to the indoor space IS as a relatively high-temperature air-conditioning air SA.

〔デシカント装置〕
デシカント装置は、室外空間ＯＳから取り込んだ空気を室内空間ＩＳへ供給する給気通路Ｒ１と、室内空間ＩＳから取り出した空気を室外空間ＯＳへ排気する排気通路Ｒ２と、給気通路Ｒ１に配置される第１給気領域Ｄ１ａと排気通路Ｒ２に配置される第１排気領域Ｄ１ｂとの間で通気性吸湿体から成るデシカントロータＤ１ｃを回転駆動させて第１給気領域Ｄ１ａ及び第１排気領域Ｄ１ｂを通過する空気の除湿及び加湿を行う第１ロータ部Ｄ１と、給気通路Ｒ１の第１給気領域Ｄ１ａよりも下流側に配置される第２給気領域Ｄ２ａと排気通路Ｒ２における第１排気領域Ｄ１ｂよりも上流側に配置される第２排気領域Ｄ２ｂとの間で通気性体からなる顕熱ロータＤ２ｃを回転駆動させて第２給気領域Ｄ２ａを通過する空気と第２排気領域Ｄ２ｂを通過する空気とを熱交換する第２ロータ部Ｄ２と、給気通路Ｒ１に空気を圧送する第２ファンＦ２と、排気通路Ｒ２に空気を圧送する第１ファンＦ１とを備えている。
制御装置Ｓは、給気通路Ｒ１及び排気通路Ｒ２の圧力損失等を考慮して、給気通路Ｒ１を通流する空気流量と排気通路Ｒ２を通流する空気流量とが略同一となるように、第１ファンＦ１及び第２ファンＦ２の回転数を制御する。 [Desicant device]
The desiccant device is disposed in an air supply passage R1 that supplies air taken from the outdoor space OS to the indoor space IS, an exhaust passage R2 that exhausts air taken from the indoor space IS to the outdoor space OS, and an air supply passage R1. The desiccant rotor D1c made of a breathable hygroscopic material is rotationally driven between the first air supply region D1a and the first exhaust region D1b arranged in the exhaust passage R2, thereby rotating the first air supply region D1a and the first exhaust region D1b. The first rotor part D1 that dehumidifies and humidifies the air passing through the air, the second air supply region D2a disposed on the downstream side of the first air supply region D1a of the air supply passage R1, and the first exhaust in the exhaust passage R2. The air passing through the second air supply region D2a by rotating the sensible heat rotor D2c made of a gas permeable body between the second exhaust region D2b disposed upstream of the region D1b and the second exhaust region D2 A second rotor section D2 of the air heat exchanger that passes through, and a second fan F2 to pump air into the air supply passage R1, and a first fan F1 to pump air to the exhaust passage R2.
The control device S takes into consideration the pressure loss of the supply passage R1 and the exhaust passage R2, and the like so that the air flow rate through the supply passage R1 and the air flow rate through the exhaust passage R2 are substantially the same. The rotational speeds of the first fan F1 and the second fan F2 are controlled.

ここで、第１ロータ部Ｄ１の構成の説明を加える。
第１ロータ部Ｄ１に設けられるデシカントロータＤ１ｃは、モータ等の回転機構部Ｍ１により、回転される回転軸に中心部が固定されて比較的低速の所定の回転速度で回転駆動し、複数の通路に配設される領域Ｄ１ａ、Ｄ１ｂを横断する姿勢で配設された円盤状又は円柱状の部材として構成されている。当該デシカントロータＤ１ｃは、回転軸に沿う方向に貫通する多数の通路が形成されたハニカム状に形成されており、各領域Ｄ１ａ、Ｄ１ｂにおいて空気がデシカントロータＤ１ｃを貫通する状態で通過する。当該デシカントロータＤ１ｃは、ゼオライト、シリカゲル、活性炭等の公知の吸着剤を担持して、通気性吸湿体とされている。
このようなデシカントロータＤ１ｃを備えたロータ部Ｄ１は、第１給気領域Ｄ１ａ、第１排気領域Ｄ１ｂのうち、第１給気領域Ｄ１ａに比較的低温の空気が通過することにより、当該空気がデシカントロータＤ１ｃの吸湿時の放熱作用による温度上昇を伴って除湿され、それによりデシカントロータＤ１ｃは空気の水分を吸着した状態となる。その水分を吸着したデシカントロータＤ１ｃの部分が上記回転駆動により第１排気領域Ｄ１ｂに移動することになる。
一方、第１排気領域Ｄ１ｂに比較的高温の空気が通過することで、その空気はデシカントロータＤ１ｃの放湿時の吸熱作用による温度低下を伴って加湿され、それによりデシカントロータＤ１ｃは上記吸着した水分を脱着させて再生されることとなる。その再生されたデシカントロータＤ１ｃの部分が上記回転駆動により第１給気領域Ｄ１ａに移動することになる。
このようにして、ロータ部Ｄ１は、第１給気領域Ｄ１ａ及び第１排気領域Ｄ１ｂを通過する夫々の空気の除湿と加湿とを行うことができるように構成されている。 Here, a description of the configuration of the first rotor part D1 will be added.
The desiccant rotor D1c provided in the first rotor part D1 is driven by a rotation mechanism part M1 such as a motor, the center part of which is fixed to the rotating shaft to be rotated at a predetermined relatively low rotational speed. It is comprised as a disk-shaped or column-shaped member arrange | positioned with the attitude | position crossing the area | regions D1a and D1b arrange | positioned in this. The desiccant rotor D1c is formed in a honeycomb shape having a large number of passages penetrating in the direction along the rotation axis, and air passes through the desiccant rotor D1c in each of the regions D1a and D1b. The desiccant rotor D1c carries a known adsorbent such as zeolite, silica gel, activated carbon, etc., and is a breathable moisture absorber.
The rotor portion D1 having such a desiccant rotor D1c has a relatively low temperature air passing through the first air supply region D1a out of the first air supply region D1a and the first exhaust region D1b. The desiccant rotor D1c is dehumidified with an increase in temperature due to heat dissipation during moisture absorption, and the desiccant rotor D1c is in a state of adsorbing moisture from the air. The portion of the desiccant rotor D1c that has adsorbed the moisture moves to the first exhaust region D1b by the rotational drive.
On the other hand, when relatively high-temperature air passes through the first exhaust region D1b, the air is humidified with a decrease in temperature due to the endothermic action of the desiccant rotor D1c when the moisture is released, whereby the desiccant rotor D1c is adsorbed. It is regenerated by desorbing moisture. The regenerated portion of the desiccant rotor D1c moves to the first air supply region D1a by the rotational drive.
In this way, the rotor part D1 is configured to be able to dehumidify and humidify each of the air passing through the first air supply region D1a and the first exhaust region D1b.

第２ロータ部Ｄ２は、顕熱ロータＤ２ｃが吸着剤が担持されていない点を除き、第１ロータ部Ｄ１と同一の構成を有しているため、ここでは、その詳細な説明を割愛する。   Since the second rotor part D2 has the same configuration as the first rotor part D1 except that the sensible heat rotor D2c does not carry an adsorbent, its detailed description is omitted here.

本発明の空調システム１００にあっては、給気通路Ｒ１及び排気通路Ｒ２を通過する空気を加熱・冷却するべく、以下のように構成されている。
即ち、エンジン冷却水循環路Ｃ２を通流するエンジン冷却水と排気通路Ｒ２を通流する空気とを熱交換する第１熱交換器ＥＸ１を、排気通路Ｒ２の第１排気領域Ｄ１ｂと第２排気領域Ｄ２ｂとの間に備える。
説明を加えると、第１熱交換器ＥＸ１は、エンジン冷却水循環路Ｃ２において、エンジン冷却水の流れ方向で、エンジンジャケット２２ａから送り出されたエンジン冷却水が第１熱交換器ＥＸ１とラジエータとしての熱交換器２２ｃとを記載の順に通流するように配設されている。これにより、エンジン冷却水循環路Ｃ２を循環するエンジン冷却水のうち、エンジンジャケット２２ａを出た後の比較的高温（例えば、７０℃程度）のエンジン冷却水にて排気通路Ｒ２の第１排気領域Ｄ１ｂと第２排気領域Ｄ２ｂとの間を通流する空気を加熱できる。 The air conditioning system 100 of the present invention is configured as follows in order to heat and cool the air passing through the air supply passage R1 and the exhaust passage R2.
That is, the first heat exchanger EX1 that exchanges heat between the engine coolant that flows through the engine coolant circulation path C2 and the air that flows through the exhaust passage R2 is connected to the first exhaust region D1b and the second exhaust region of the exhaust passage R2. Provided with D2b.
In other words, the first heat exchanger EX1 is configured such that the engine cooling water sent from the engine jacket 22a in the engine cooling water circulation path C2 in the flow direction of the engine cooling water is heated with the first heat exchanger EX1 and the radiator. It arrange | positions so that it may flow through the exchanger 22c in the order of description. As a result, of the engine coolant that circulates through the engine coolant circulation path C2, the first exhaust region D1b of the exhaust passage R2 is made of engine coolant having a relatively high temperature (eg, about 70 ° C.) after exiting the engine jacket 22a. And the air flowing between the second exhaust region D2b can be heated.

更に、本発明にあっては、ＧＨＰの冷房運転時（図１に示す回路状態の時）に、冷媒循環路Ｃ１で蒸発器Ｊとしての室内熱交換器２５ａと圧縮機２１との間を通流する冷媒と給気通路Ｒ１を通流する空気とを熱交換する第２熱交換器ＥＸ２を、給気通路Ｒ１を通流する空気の流れ方向で第１給気領域Ｄ１ａの上流側に備えている。
説明を加えると、冷媒循環路Ｃ１には、ＧＨＰの冷房運転時に、冷媒循環路Ｃ１で蒸発器Ｊとしての室内熱交換器２５ａと圧縮機２１との間を通流する冷媒を第２熱交換器ＥＸ２の側へ導く状態（図１に示す回路状態）と、ＧＨＰの暖房運転時に、冷媒循環路Ｃ１で蒸発器Ｊとしての室内熱交換器２５ａと圧縮機２１との間を通流する冷媒を第２熱交換器ＥＸ２の側へ導かず圧縮機２１と凝縮器Ｇとしての室内熱交換器２５ａとを直接接続する状態（図２に示す回路状態）とを切り替える第１三方弁Ｖ１が設けられている。これにより、ＧＨＰの冷房運転時においては、図３でＰ１４−Ｐ１５間に示すように、蒸発器Ｊを出た後で冷熱（潜熱＋顕熱）を保有する冷媒を第２熱交換器ＥＸ２に導くことができ、第２熱交換器ＥＸ２にて室外空気ＯＡを冷却している。尚、図３におけるＰ１１〜Ｐ１５は、図１の冷媒循環路Ｃ１でのＰ１１〜Ｐ１５における値を示している。
尚、図３に示すように、制御装置Ｓは、第２熱交換器ＥＸ２にて冷媒の冷熱が放熱される関係で、圧縮機２１の圧縮仕事ΔＷを、従来技術における圧縮機２１の圧縮仕事ΔＷ'（図５に図示）よりも大きくしている。 Furthermore, in the present invention, during the cooling operation of the GHP (in the circuit state shown in FIG. 1), the refrigerant circuit C1 passes between the indoor heat exchanger 25a as the evaporator J and the compressor 21. A second heat exchanger EX2 for exchanging heat between the flowing refrigerant and the air flowing through the supply passage R1 is provided upstream of the first supply region D1a in the flow direction of the air flowing through the supply passage R1. ing.
In other words, in the refrigerant circulation path C1, the refrigerant flowing between the indoor heat exchanger 25a as the evaporator J and the compressor 21 in the refrigerant circulation path C1 during the cooling operation of the GHP is subjected to the second heat exchange. Refrigerant (the circuit state shown in FIG. 1) led to the side of the evaporator EX2 and refrigerant flowing between the indoor heat exchanger 25a as the evaporator J and the compressor 21 in the refrigerant circulation path C1 during the heating operation of the GHP The first three-way valve V1 is provided for switching between a state (circuit state shown in FIG. 2) in which the compressor 21 and the indoor heat exchanger 25a serving as the condenser G are not directly connected to the second heat exchanger EX2. It has been. As a result, during the cooling operation of the GHP, as shown between P14 and P15 in FIG. 3, the refrigerant that holds the cold (latent heat + sensible heat) after leaving the evaporator J is transferred to the second heat exchanger EX2. The outdoor air OA is cooled by the second heat exchanger EX2. In addition, P11-P15 in FIG. 3 has shown the value in P11-P15 in the refrigerant circuit C1 of FIG.
As shown in FIG. 3, the control device S uses the second heat exchanger EX2 to dissipate the cold heat of the refrigerant, so that the compression work ΔW of the compressor 21 is reduced by the compression work ΔW of the compressor 21 in the prior art. It is larger than ΔW ′ (shown in FIG. 5).

〔除湿冷房運転〕
本発明の空調システム１００では、ＧＨＰにて冷房運転を実行している時に、デシカント装置にて空調用空気ＳＡを除湿冷却することで、所謂、除湿冷房運転を実行可能に構成されている。
制御装置Ｓは、除湿冷房運転において、ＧＨＰ側では、四方弁２６を図１に示す状態に切り替えると共に、第２熱交換器ＥＸ２に冷媒が循環するように第１三方弁Ｖ１の開閉状態を制御すると共に、デシカント装置側では、第１ファンＦ１及び第２ファンＦ２を所定の回転速度で働かせると共に、第１ロータ部Ｄ１の回転機構部Ｍ１及び第２ロータ部Ｄ２の回転機構部Ｍ２を働かせて、デシカントロータＤ１ｃ及び顕熱ロータＤ２ｃを回転駆動させる。
当該除湿冷房運転によるデシカント装置側での空気線図を図４に示す。図４で、一点鎖線、二点鎖線は従来技術（第２熱交換器ＥＸ２を設けない構成）の空気線図を示すものであり、実線、太実線は本発明の空気線図を示すものである。
図４から、第２熱交換器ＥＸ２を設け、第１給気領域Ｄ１ａを通過する空気の温度を、約５℃程度（Ｐ１―Ｐ２間の温度）低下させることにより、本発明での除湿量Ｈを従来技術の除湿量Ｈ’からΔＨ（約２０％）増加できており、除湿性能の向上が見込まれる。
尚、当該空気線図におけるＰ１−Ｐ８は、図１におけるＰ１−Ｐ８での空気の状態を示すものである。 [Dehumidifying and cooling operation]
The air conditioning system 100 according to the present invention is configured to perform a so-called dehumidifying and cooling operation by dehumidifying and cooling the air-conditioning air SA with a desiccant device when the cooling operation is being performed by the GHP.
In the dehumidifying and cooling operation, the control device S switches the four-way valve 26 to the state shown in FIG. 1 on the GHP side and controls the open / closed state of the first three-way valve V1 so that the refrigerant circulates in the second heat exchanger EX2. At the same time, on the desiccant device side, the first fan F1 and the second fan F2 are operated at a predetermined rotational speed, and the rotation mechanism unit M1 of the first rotor unit D1 and the rotation mechanism unit M2 of the second rotor unit D2 are operated. The desiccant rotor D1c and the sensible heat rotor D2c are rotationally driven.
FIG. 4 shows an air diagram on the desiccant device side in the dehumidifying and cooling operation. In FIG. 4, the one-dot chain line and the two-dot chain line show the air diagram of the prior art (a configuration in which the second heat exchanger EX2 is not provided), and the solid line and the thick solid line show the air diagram of the present invention. is there.
From FIG. 4, the second heat exchanger EX2 is provided, and the temperature of the air passing through the first air supply region D1a is reduced by about 5 ° C. (temperature between P1 and P2), whereby the dehumidification amount in the present invention. H can be increased by ΔH (about 20%) from the dehumidifying amount H ′ of the prior art, and an improvement in dehumidifying performance is expected.
In addition, P1-P8 in the said air diagram shows the state of the air in P1-P8 in FIG.

〔暖房運転〕
本発明の空調システム１００では、四方弁２６を図２に示す状態に切り替えることで、暖房運転をも実行可能に構成されている。
制御装置Ｓは、暖房運転において、ＧＨＰ側では、四方弁２６を図２に示す状態に切り替えると共に、第２熱交換器ＥＸ２に冷媒が循環しないように第１三方弁Ｖ１の開閉状態を制御すると共に、デシカント装置側では、第１ファンＦ１及び第２ファンＦ２を所定の回転速度で働かせると共に、第１ロータ部Ｄ１の回転機構部Ｍ１を働かせずデシカントロータＤ１ｃの回転を停止状態で、第２ロータ部Ｄ２の回転機構部Ｍ２を働かせて、顕熱ロータＤ２ｃを回転駆動させる。
即ち、当該暖房運転においては、デシカント装置は、室内空気ＲＡと室外空気ＯＡとを熱交換する装置として機能する。
尚、当該暖房運転にあっては、第２熱交換器ＥＸ２へ冷媒は導かれないため、冷媒循環路Ｃ１を循環する冷媒のＰ１１〜Ｐ１４（Ｐ１５はＰ１４と同一）の状態は、図５に示す従来技術のＰＨ線図のＰ１１’〜Ｐ１４’と略同等の値となる。 [Heating operation]
In the air conditioning system 100 of the present invention, the heating operation can also be executed by switching the four-way valve 26 to the state shown in FIG.
In the heating operation, the control device S switches the four-way valve 26 to the state shown in FIG. 2 on the GHP side, and controls the open / close state of the first three-way valve V1 so that the refrigerant does not circulate in the second heat exchanger EX2. At the same time, on the desiccant device side, the first fan F1 and the second fan F2 are operated at a predetermined rotation speed, the rotation mechanism M1 of the first rotor part D1 is not operated, and the rotation of the desiccant rotor D1c is stopped. The sensible heat rotor D2c is rotationally driven by operating the rotation mechanism part M2 of the rotor part D2.
That is, in the heating operation, the desiccant device functions as a device for exchanging heat between the indoor air RA and the outdoor air OA.
In the heating operation, since the refrigerant is not guided to the second heat exchanger EX2, the state of the refrigerant P11 to P14 (P15 is the same as P14) circulating in the refrigerant circuit C1 is shown in FIG. It becomes a value substantially equivalent to P11'-P14 'of the prior art PH diagram shown.

〔別実施形態〕
（１）本発明の空調システム１００の別実施形態にあっては、図６に示すように、上記実施形態の空調システム１００に加え、第１排気領域Ｄ１ｂと第２排気領域Ｄ２ｂとの間に、第３熱交換器ＥＸ３を備えている点を特徴としている。
即ち、ＧＨＰの冷房運転時（図６に示す回路状態にある時）において冷媒循環路Ｃ１で圧縮機２１と凝縮器Ｇとしての室外熱交換器２３ａとの間を通流する冷媒と排気通路Ｒ２を通流する空気とを熱交換する第３熱交換器ＥＸ３を備え、第１熱交換器ＥＸ１と第３熱交換器ＥＸ３とを、排気通路Ｒ２の第１排気領域Ｄ１ｂと第２排気領域Ｄ２ｂとの間に、排気通路Ｒ２での空気の流れ方向で記載の順に備える。
説明を加えると、冷媒循環路Ｃ１には、ＧＨＰの冷房運転時に、冷媒循環路Ｃ１の圧縮機２１と凝縮器Ｇとしての室外熱交換器２３ａとの間を通流する冷媒を第３熱交換器ＥＸ３の側へ導く状態（図５に示す回路状態）と、ＧＨＰの暖房運転時に、冷媒循環路Ｃ１を通流する冷媒を第３熱交換器ＥＸ３の側へ導かず圧縮機２１と蒸発器Ｊとしての室外熱交換器２３ａとを直接接続する状態（図示省略）とを切り替える第２三方弁Ｖ２が設けられている。これにより、ＧＨＰの冷房運転時においては、第３熱交換器ＥＸ３に、圧縮機２１にて圧縮された比較的高温（例えば、７３℃〜９０℃程度）の冷媒を通流させることができ、第１排気領域Ｄ１ｂと第２排気領域Ｄ２ｂとの間を通流する空気を、第１熱交換器ＥＸ１に加え、当該第３熱交換器ＥＸ３でも加熱することができる。
尚、制御装置Ｓは、圧縮機２１による圧縮仕事を可変に設定可能に構成されており、当該別実施形態にあっては、当該圧縮機２１による圧縮仕事を増加させ、圧縮機２１にて圧縮された冷媒の温度を、９０℃程度まで昇温させて、第３熱交換器ＥＸ３への冷媒の流入温度を、第１熱交換器ＥＸ１へ流入するエンジン冷却水の最高温度（例えば、７０℃）よりも高くして、第１排気領域Ｄ１ｂを通過する空気の温度を十分に昇温させる。これにより、第１ロータ部Ｄ１のデシカントロータＤ１ｃを、第１排気領域Ｄ１ｂにて十分に再生するし、第１給気領域Ｄ１ｂでの吸湿性能を向上させている。 [Another embodiment]
(1) In another embodiment of the air-conditioning system 100 of the present invention, as shown in FIG. 6, in addition to the air-conditioning system 100 of the above-described embodiment, between the first exhaust region D1b and the second exhaust region D2b. The third heat exchanger EX3 is provided.
That is, during the cooling operation of the GHP (when it is in the circuit state shown in FIG. 6), the refrigerant and the exhaust passage R2 that flow between the compressor 21 and the outdoor heat exchanger 23a as the condenser G in the refrigerant circulation path C1. A third heat exchanger EX3 for exchanging heat with the air flowing therethrough, the first heat exchanger EX1 and the third heat exchanger EX3 being connected to the first exhaust region D1b and the second exhaust region D2b of the exhaust passage R2. Are provided in the order of description in the air flow direction in the exhaust passage R2.
In other words, in the refrigerant circulation path C1, the refrigerant flowing between the compressor 21 in the refrigerant circulation path C1 and the outdoor heat exchanger 23a as the condenser G is subjected to the third heat exchange during the cooling operation of the GHP. The compressor 21 and the evaporator without guiding the refrigerant flowing through the refrigerant circulation path C1 to the third heat exchanger EX3 side during the heating operation of the GHP (the circuit state shown in FIG. 5) and the GHP heating operation A second three-way valve V2 for switching between a state (not shown) directly connected to the outdoor heat exchanger 23a as J is provided. Thereby, at the time of the cooling operation of GHP, the relatively high temperature (for example, about 73 ° C. to 90 ° C.) refrigerant compressed by the compressor 21 can be passed through the third heat exchanger EX3. The air flowing between the first exhaust region D1b and the second exhaust region D2b can be added to the first heat exchanger EX1 and heated by the third heat exchanger EX3.
The control device S is configured so that the compression work by the compressor 21 can be set variably. In the other embodiment, the compression work by the compressor 21 is increased and the compression work is performed by the compressor 21. The temperature of the generated refrigerant is raised to about 90 ° C., and the inflow temperature of the refrigerant to the third heat exchanger EX3 is set to the maximum temperature (for example, 70 ° C.) of the engine cooling water flowing into the first heat exchanger EX1. ) To sufficiently increase the temperature of the air passing through the first exhaust region D1b. Thereby, the desiccant rotor D1c of the first rotor part D1 is sufficiently regenerated in the first exhaust region D1b, and the moisture absorption performance in the first supply region D1b is improved.

（２）上記実施形態においては、第１ロータ部Ｄ１及び第２ロータ部Ｄ２は、夫々１つづつ設ける構成を例示したが、別に複数設ける構成を採用しても構わない。 (2) In the above embodiment, the configuration in which the first rotor portion D1 and the second rotor portion D2 are provided one by one is exemplified, but a configuration in which a plurality of first rotor portions D1 and second rotor portions D2 are separately provided may be employed.

（３）第１ファンＦ１は、排気通路Ｒ２で第１排気領域Ｄ１ｂの下流側に設けられる例を示したが、排気通路Ｒ２上であれば、どこに設けられていても良い。
また、第２ファンＦ２は、給気通路Ｒ１で第１給気領域Ｄ１ａの上流側に設けられる例を示したが、給気通路Ｒ１上であれば、どこに設けられていても良い。 (3) Although the example in which the first fan F1 is provided on the downstream side of the first exhaust region D1b in the exhaust passage R2 is shown, it may be provided anywhere on the exhaust passage R2.
In addition, although the example in which the second fan F2 is provided on the upstream side of the first supply region D1a in the supply passage R1 is shown, it may be provided anywhere on the supply passage R1.

（４）上記別実施形態１において、例えば、除湿冷房運転時に、外部に設けられる設定部（図示せず）からの除湿設定値に基づいて、圧縮機２１による圧縮仕事を制御する構成を採用しても構わない。
例えば、除湿設定値が『除湿量：低』から『除湿量：高』へ変更設定された場合、圧縮機２１の圧縮仕事を大きく設定することで、当該圧縮機２１にて圧縮される冷媒の温度を昇温させ、第３熱交換器ＥＸ３を通過した後の空気を昇温させ、第１ロータ部の第１排気領域Ｄ１ｂを通過するデシカントロータＤ１ｃの再生をより良好に行う形態で、第１給気領域Ｄ１ａを通過する空気の除湿量を向上させることができる。 (4) In the first embodiment, for example, a configuration is adopted in which the compression work by the compressor 21 is controlled based on a dehumidification set value from a setting unit (not shown) provided outside during dehumidifying and cooling operation. It doesn't matter.
For example, when the dehumidification set value is changed and set from “dehumidification amount: low” to “dehumidification amount: high”, the compression work of the compressor 21 is set to be large so that the refrigerant compressed by the compressor 21 is set. In a form in which the temperature is increased, the air after passing through the third heat exchanger EX3 is heated, and the regeneration of the desiccant rotor D1c passing through the first exhaust region D1b of the first rotor portion is performed better. The dehumidification amount of the air passing through the one air supply region D1a can be improved.

（５）上記実施形態では、除湿冷房運転と暖房運転とを切り替え実行可能な構成を示したが、四方弁２６、第１三方弁Ｖ１を設けない構成を採用し、除湿冷房運転を専用で行う空調システムとすることができる。 (5) In the above-described embodiment, a configuration capable of switching between the dehumidifying and cooling operation and the heating operation has been shown. However, a configuration in which the four-way valve 26 and the first three-way valve V1 are not provided is employed, and the dehumidifying and cooling operation is performed exclusively. It can be an air conditioning system.

本発明の空調システムは、ＧＨＰとデシカント装置とを備えたものにおいて、ガスエンジンの立ち上がり時であっても、デシカントロータの再生を適切に行い、デシカント装置を介して室内空間へ供給される空調用空気の湿度を十分に下げることができる空調システムとして、有効に利用可能である。   The air-conditioning system of the present invention includes a GHP and a desiccant device. For the air-conditioning system that appropriately regenerates the desiccant rotor and is supplied to the indoor space via the desiccant device even when the gas engine starts up. It can be effectively used as an air conditioning system that can sufficiently reduce the humidity of air.
