Description

本発明は、気化用空気により揮発性液体を気化させるときの気化熱で冷却対象空気を冷却する間接気化冷却手段を備えた間接気化冷却式の冷房システムに関する。   The present invention relates to an indirect evaporative cooling type cooling system provided with indirect evaporative cooling means for cooling air to be cooled with heat of vaporization when vaporizing volatile liquid with evaporating air.

かかる間接気化冷却式の冷房システムは、間接気化冷却手段にて冷却対象空気を冷却して生成された冷却空気を空調対象室に供給して、空調対象室を冷房するものである。
このような間接気化冷却手段は、気化用空気を通風させると共にその気化用空気の通風により気化可能な状態で揮発性液体が供給される気化用流路と冷却対象空気を通風させる冷却用流路とを熱交換可能に備えて構成される。又、冷却対象空気を冷却用流路を通して通風させて冷却空気として送出する給気ファン、及び、気化用空気を気化用流路を通して通風させる排気ファンが設けられる（例えば、特許文献１、２参照。）。 Such an indirect evaporative cooling type cooling system cools the air-conditioning target room by supplying cooling air generated by cooling the air to be cooled by the indirect evaporative cooling means to the air-conditioning target room.
Such an indirect evaporative cooling means includes an evaporating channel for supplying the volatile liquid in a state where the evaporating air is ventilated and being able to evaporate by the evaporating air, and a cooling channel for allowing the air to be cooled to be ventilated. And is configured to be capable of heat exchange. In addition, an air supply fan that ventilates the cooling target air through the cooling flow path and sends it out as cooling air, and an exhaust fan that ventilates the vaporization air through the vaporization flow path (see, for example, Patent Documents 1 and 2). .)

従来、このような間接気化冷却手段を用いた冷房システムにおいては、上記の特許文献１、２には記載されていないが、給気ファンは、屋外の空気、即ち、外気を吸い込んで冷却対象空気として間接気化冷却手段の冷却用流路を通風させて空調対象室に送出する形態で通風作用させるように設けられ、排気ファンは、空調対象室内の空気を吸い込んで気化用空気として間接気化冷却手段の気化用流路を通風させて屋外に送出する形態で通風作用するように設けられていた。
ちなみに、本願では、「気化」は「蒸発」と同義で使用し、「気化熱」は「蒸発熱」を意味する。 Conventionally, in such a cooling system using indirect evaporative cooling means, although not described in the above-mentioned Patent Documents 1 and 2, the air supply fan sucks outdoor air, that is, air to be cooled by sucking outside air. As an indirect evaporative cooling means, the cooling fan of the indirect evaporative cooling means is provided so as to be ventilated in a form to be ventilated and sent to the air conditioned room, and the exhaust fan sucks the air in the air conditioned room as evaporating air It was provided so that it might ventilate in the form which ventilated the flow path of this and sends it out outdoors.
Incidentally, in this application, “vaporization” is used synonymously with “evaporation”, and “heat of vaporization” means “heat of evaporation”.

しかしながら、従来の間接気化冷却式の冷房システムでは、外気を冷却対象空気とするので、夏季等、外気温度が高い時期では、冷却対象空気の温度が高いため、空調対象室を冷房するのに適応した低温の冷却空気を得ることができない場合があった。
従って、間接気化冷却式の冷房システムの冷房能力を向上する上で、改善の余地があった。 However, in the conventional indirect evaporative cooling type cooling system, the outside air is used as the air to be cooled, so the temperature of the air to be cooled is high at the time when the outside air temperature is high, such as in summer. In some cases, it was not possible to obtain low-temperature cooling air.
Therefore, there is room for improvement in improving the cooling capacity of the indirect evaporative cooling type cooling system.

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、冷房能力を向上し得る間接気化冷却式の冷房システムを提供することにある。   The present invention has been made in view of such circumstances, and an object thereof is to provide an indirect evaporative cooling type cooling system capable of improving the cooling capacity.

本発明に係る間接気化冷却式の冷房システムの第１特徴構成は、
空調対象室内に冷却空気を吹き出す吹出口、空調対象室内の空気を吸い込む吸込口、気化用空気により揮発性液体を気化させるときの気化熱で冷却対象空気を冷却する間接気化冷却手段、外気を取り込む外気取入口、及び、前記間接気化冷却手段から排出された気化用空気を屋外に排出する排気口が設けられ、
前記間接気化冷却手段が、気化用空気を通風させると共にその気化用空気の通風により気化可能な状態で揮発性液体が供給される気化用流路と冷却対象空気を通風させる冷却用流路とを熱交換可能に備えて構成され、
冷却対象空気を前記冷却用流路を通風させて冷却空気として前記吹出口に送出する給気ファン、及び、気化用空気を前記気化用流路を通風させて前記排気口に送出する排気ファンが設けられ、
前記給気ファンを前記外気取入口に吸込作用させて、外気を冷却対象空気として前記冷却用流路を通風させる外気取入冷房モードと、前記給気ファンを前記吸込口に吸込作用させて前記空調対象室内の空気を冷却対象空気として前記冷却用流路を通風させる室内気循環冷房モードとに運転モードを択一的に設定可能な運転モード切換手段が設けられている点にある。 The first characteristic configuration of the indirect evaporative cooling type cooling system according to the present invention is:
Air outlet that blows cooling air into the air-conditioning target room, inlet port that sucks in air inside the air-conditioning target room, indirect evaporative cooling means that cools the air to be cooled with the heat of vaporization when vaporizing the volatile liquid, and takes in outside air An outside air inlet and an exhaust port for discharging the vaporizing air discharged from the indirect evaporative cooling means to the outside;
The indirect evaporative cooling means ventilates the vaporizing air and supplies a vaporizing channel to which the volatile liquid is supplied in a state capable of being vaporized by the vaporizing air and a cooling channel for allowing the cooling target air to ventilate. Configured for heat exchange,
An air supply fan that sends cooling target air through the cooling flow path and sends it as cooling air to the outlet, and an exhaust fan that sends vaporization air through the vaporization flow path and sends it to the exhaust port Provided,
The air supply fan is sucked into the outside air inlet, and the outside air intake cooling mode in which the outside air is cooled as air to be cooled and passed through the cooling channel, and the air supply fan is sucked into the suction port to There is an operation mode switching means that can alternatively set the operation mode to the indoor air circulation cooling mode in which the air in the air-conditioning target room is cooled as the cooling target air.

上記特徴構成によれば、外気よりも空調対象室内の空気の方が温度が低い場合は、運転モード切換手段により運転モードを室内気循環冷房モードに設定し、一方、空調対象室内の空気よりも外気の方が温度が低い場合は、運転モード切換手段により運転モードを外気取入冷房モードに設定して運転することができる。
例えば、夏季の日中等、外気よりも空調対象室内の空気の方が温度が低いときは、室内気循環冷房モードに設定して運転する。一方、例えば、夏季の夜間や早朝等、空調対象室の空気よりも外気の方が温度が低いときは、外気取入冷房モードに設定して運転する。
つまり、外気と空調対象室内の空気で、温度が低い方の空気を冷却対象空気として運転することができるので、空調対象室を冷房するのに適応した低温の冷却空気を得ることができる。
従って、冷房能力を向上し得る間接気化冷却式の冷房システムを提供することができるようになった。 According to the above characteristic configuration, when the temperature of the air in the air-conditioning target room is lower than that of the outside air, the operation mode is set to the indoor air circulation cooling mode by the operation mode switching means, while the air in the air-conditioning target room is set to be When the temperature of the outside air is lower, the operation mode can be set to the outside air intake cooling mode by the operation mode switching means.
For example, when the temperature of the air in the air-conditioned room is lower than that of the outside air, such as during the daytime in summer, the operation is performed by setting the indoor air circulation cooling mode. On the other hand, for example, when the temperature of the outside air is lower than the air in the air-conditioning target room, such as at night in the summer or early morning, the operation is performed by setting the outside air intake cooling mode.
In other words, since the outside air and the air in the air-conditioning target room can be operated as the cooling target air, the low-temperature cooling air suitable for cooling the air-conditioning target room can be obtained.
Therefore, an indirect evaporative cooling type cooling system capable of improving the cooling capacity can be provided.

As the air conditioning target room, the first air conditioning target room and the second air conditioning target room are targeted,
As the air outlet, a first air outlet corresponding to the first air-conditioning target room and a second air outlet corresponding to the second air-conditioning target room are provided, and the suction port corresponds to the first air-conditioning target room. A first suction port and a second suction port corresponding to the second air-conditioned room,
There is provided an outlet switching means capable of switching between a state in which the cooling air delivered from the cooling flow path by the air supply fan is sent to the first outlet and a state in which the cooling air is sent to the second outlet. And
The operation mode switching means causes the exhaust fan to be sucked into the first suction port as the outside air intake cooling mode so that the air in the first air-conditioning target room is vaporized air and the ventilation channel is ventilated. A first indoor air discharge type outside air intake cooling mode, and the exhaust fan is sucked into the second suction port so that the air in the second air-conditioning target room is vaporized air and the ventilation channel is ventilated. The second indoor air discharge-type outdoor air intake cooling mode, and the indoor air circulation cooling mode to cool the air in the first air-conditioning target room by causing the air supply fan to suck into the first suction port. An outside air discharge type first indoor air circulation cooling mode in which the cooling channel is ventilated as the target air and the exhaust fan is sucked into the outside air intake port so that the outside air is ventilated as the vaporizing air. When The air supply fan is sucked into the second suction port, the air in the second air-conditioning target room is used as cooling target air, and the cooling flow passage is blown, and the exhaust fan is sucked into the outside air inlet. The configuration is such that four types of operation modes of an outside air discharge type second indoor air circulation cooling mode in which the outside air is used as vaporizing air and are passed through the vaporizing flow path can be alternatively set.

上記特徴構成によれば、外気、第１空調対象室内の空気、第２空調対象室内の空気のうちで、第１空調対象室内の空気の温度が最低の場合は、運転モード切換手段により外気放出式の第１室内気循環冷房モードに設定し、第２空調対象室内の空気の温度が最低の場合は、運転モード切換手段により外気放出式の第２室内気循環冷房モードに設定し、外気の温度が最低の場合は、運転モード切換手段により第１室内気放出式の外気取入冷房モードか第２室内気放出式の外気取入冷房モードのいずれかに設定して運転することができる。
又、外気取入冷房モードでも気化用空気の温度が高いほど、又は、湿度が低いほど、揮発性液体の気化を促進させて、冷却対象空気を冷却する能力を向上することができる。
そこで、外気、第１空調対象室内の空気、第２空調対象室内の空気のうちで外気の温度が最低の場合は、第１空調対象室内の空気と第２空調対象室内の空気とを比較して、第１空調対象室内の空気の方が温度が高い又は湿度が低い場合は、運転モード切換手段により第１室内気放出式の外気取入冷房モードに設定して運転し、一方、第２空調対象室内の空気の方が温度が高い又は湿度が低い場合は、運転モード切換手段により第２室内気放出式の外気取入冷房モードに設定して運転することができる。
従って、冷却対象空気として用いる空気を外気、第１空調対象室内の空気及び第２空調対象室内の空気の３種の空気から選ぶことができて、より一層温度が低い空気を冷却対象空気として用いて運転することができるので、冷房能力をより一層向上することができる。 According to the above characteristic configuration, when the temperature of the air in the first air-conditioning target room is the lowest among the outside air, the air in the first air-conditioning target room, and the air in the first air-conditioning target room, the outside air is released by the operation mode switching means. When the temperature of the air in the second air-conditioning target room is the lowest, the operation mode switching means sets the second indoor air circulation cooling mode of the outside air to the outside air-conditioning cooling mode. When the temperature is the lowest, the operation mode switching means can be set to either the first indoor air discharge type outside air intake cooling mode or the second indoor air discharge type outside air intake cooling mode.
Further, the ability to cool the air to be cooled can be improved by promoting the vaporization of the volatile liquid as the temperature of the vaporizing air is higher or the humidity is lower even in the outside air intake cooling mode.
Therefore, when the temperature of the outside air is the lowest among the outside air, the air in the first air-conditioning target room, and the air in the second air-conditioning target room, the air in the first air-conditioning target room is compared with the air in the second air-conditioning target room. When the temperature of the air in the first air-conditioning target room is higher or the humidity is lower, the operation mode switching means sets the first indoor air discharge type outside air intake cooling mode to operate, while the second When the air in the air-conditioned room has a higher temperature or lower humidity, the operation mode switching means can set the second indoor air discharge type outside air intake cooling mode to operate.
Therefore, the air used as the air to be cooled can be selected from three types of air, that is, the outside air, the air in the first air-conditioning target room, and the air in the second air-conditioning target room, and the air having a lower temperature is used as the cooling target air. Therefore, the cooling capacity can be further improved.

第３特徴構成は、上記第２特徴構成に加えて、
前記運転モード切換手段が、前記室内気循環冷房モードとしての、前記給気ファンを前記第１吸込口に吸込作用させて前記第１空調対象室内の空気を冷却対象空気として前記冷却用流路を通風させ且つ且つ前記排気ファンを前記第２吸込口に吸込作用させて前記第２空調対象室内の空気を気化用空気として前記気化用流路を通風させる第２室内気放出式の第１室内気循環冷房モードと、前記給気ファンを前記第２吸込口に吸込作用させて前記第２空調対象室内の空気を冷却対象空気として前記冷却用流路を通風させ且つ且つ前記排気ファンを前記第１吸込口に吸込作用させて前記第１空調対象室内の空気を気化用空気として前記気化用流路を通風させる第１室内気放出式の第２室内気循環冷房モードとの２種の運転モードを加えた６種の運転モードを択一的に設定可能なように構成されている点にある。 The third feature configuration is in addition to the second feature configuration,
In the indoor air circulation cooling mode, the operation mode switching means causes the air supply fan to suck into the first suction port, and uses the air in the first air-conditioning target room as the cooling target air. A second room air discharge type first room air that ventilates and causes the exhaust fan to suck into the second suction port and causes the air in the second air-conditioning target room to evaporate as the vaporization air. In the circulation cooling mode, the air supply fan is sucked into the second suction port so that the air in the second air-conditioning target room is cooled as the cooling target air, and the exhaust fan is set in the first cooling mode. There are two operation modes: a first indoor air discharge type second indoor air circulation cooling mode in which the air in the first air-conditioning target room is caused to be sucked into the suction port and is passed through the vaporizing flow path. 6 types of driving Certain over de in that it is configured so as to selectively settable.

上記特徴構成によれば、外気、第１空調対象室内の空気、第２空調対象室内の空気のうちで、第１空調対象室内の空気の温度が最低の場合は、更に、外気と第２空調対象室内の空気とを比較して、外気の方が温度が高い又は湿度が低い場合は、運転モード切換手段により運転モードを外気放出式の第１室内気循環冷房モードに設定し、一方、第２空調対象室内の空気の方が温度が高い又は湿度が低い場合は、運転モード切換手段により運転モードを第２室内気放出式の第１室内気循環冷房モードに設定することができる。
又、外気、第１空調対象室内の空気、第２空調対象室内の空気のうちで、第２空調対象室内の空気の温度が最低の場合は、更に、外気と第１空調対象室内の空気とを比較して、外気の方が温度が高い又は湿度が低い場合は、運転モード切換手段により運転モードを外気放出式の第２室内気循環冷房モードに設定し、一方、第１空調対象室内の空気の方が温度が高い又は湿度が低い場合は、運転モード切換手段により運転モードを第１室内気放出式の第２室内気循環冷房モードに設定する。
又、外気、第１空調対象室内の空気、第２空調対象室内の空気のうちで、外気の空気の温度が最低の場合は、更に、第１空調対象室の空気と第２空調対象室内の空気とを比較して、第１空調対象室の空気の方が温度が高い又は湿度が低い場合は、運転モード切換手段により運転モードを第１室内気放出式の外気取入冷房モードに設定し、一方、第２空調対象室内の空気の方が温度が高い又は湿度が低い場合は、運転モード切換手段により運転モードを第２室内気放出式の外気取入冷房モードに設定することができる。 According to the above characteristic configuration, when the temperature of the air in the first air-conditioning target room is the lowest among the outside air, the air in the first air-conditioning target room, and the air in the second air-conditioning target room, the outside air and the second air-conditioning are further reduced. When the temperature of the outside air is higher or the humidity is lower than the air in the target room, the operation mode switching means sets the operation mode to the outside air discharge type first indoor air circulation cooling mode, When the air in the air-conditioning target room has a higher temperature or lower humidity, the operation mode can be set to the second indoor air discharge type first indoor air circulation cooling mode by the operation mode switching means.
Moreover, when the temperature of the air in the second air-conditioning target room is the lowest among the outside air, the air in the first air-conditioning target room, and the air in the second air-conditioning target room, the outside air and the air in the first air-conditioning target room If the temperature of the outside air is higher or the humidity is lower, the operation mode is set to the second indoor air circulation cooling mode of the outside air release type by the operation mode switching means, When the temperature of air is higher or the humidity is lower, the operation mode is set to the second indoor air circulation cooling mode of the first indoor air discharge type by the operation mode switching means.
In addition, when the temperature of the outside air is the lowest among the outside air, the air in the first air-conditioning target room, and the air in the second air-conditioning target room, the air in the first air-conditioning target room and the air in the second air-conditioning target room When the temperature of the air in the first air-conditioning target room is higher or the humidity is lower than the air, the operation mode is set to the first indoor air discharge type outside air intake cooling mode by the operation mode switching means. On the other hand, when the temperature of the air in the second air-conditioning target room is higher or the humidity is lower, the operation mode can be set to the second indoor air discharge type outside air intake cooling mode by the operation mode switching means.

つまり、冷却対象空気として用いる空気を外気、第１空調対象室内の空気及び第２空調対象室内の空気の３種の空気から選ぶことができ、更に、気化用空気として用いる空気を、外気、第１空調対象室内の空気及び第２空調対象室内の空気のうちの冷却対象空気として選んだ以外の２種の空気から選ぶことができることから、より一層温度が低い空気を冷却対象空気として用い、且つ、より一層温度が高い又は湿度が低い空気を気化用空気として用いて運転することができるのでので、冷房能力を更に向上することができる。   In other words, the air used as the air to be cooled can be selected from three types of air, that is, the outside air, the air in the first air-conditioning target room, and the air in the second air-conditioning target room. Since it can be selected from two types of air other than those selected as the air to be cooled among the air in the air-conditioning target room and the air in the second air-conditioning target room, air having a lower temperature is used as the cooling target air, and In addition, since it is possible to operate using air having a higher temperature or lower humidity as the vaporizing air, the cooling capacity can be further improved.

以下、各運転における制御部９の制御動作について説明を加える。
尚、第１室通常冷房運転、第１室入浴中冷房運転、第２室通常冷房運転、第２室入浴後冷房運転及両室通常冷房運転のいずれの運転でも、給水断続弁１４を開くと共に、循環遮断ダンパ３７を閉じ、並びに、給気ファン１及び排気ファン２を作動させるので、各運転の制御動作の説明では、給水断続弁１４、循環遮断ダンパ３７、給気ファン１及び排気ファン２の制御の説明を省略する。 Hereinafter, the control operation of the control unit 9 in each operation will be described.
The water supply intermittent valve 14 is opened in any of the first chamber normal cooling operation, the first chamber bathing cooling operation, the second chamber normal cooling operation, the second chamber bathing cooling operation, and the two-chamber normal cooling operation. Since the circulation shutoff damper 37 is closed and the air supply fan 1 and the exhaust fan 2 are operated, in the explanation of the control operation of each operation, the water supply interrupt valve 14, the circulation shutoff damper 37, the air supply fan 1 and the exhaust fan 2 are operated. Description of the control is omitted.

制御部９は、操作部１０の運転切換スイッチにより、第１室通常冷房運転、第２室通常冷房運転及び両室通常冷房運転のいずれかが指令されると、外気温度センサ４１、第１室温度センサ４２、第２室温度センサ４３にて夫々検出された外気温度Ｔｏ、第１室温度Ｔ１、第２室温度Ｔ２、並びに、外気湿度センサ４４、第１室湿度センサ４５、第２室湿度センサ４６にて夫々検出された外気湿度Ｈｏ、第１室湿度Ｈ１、第２室湿度Ｈ２に基づいて、第１室内気放出式の外気取入冷房モード、第２室内気放出式の外気取入冷房モード、外気放出式の第１室内気循環冷房モード、外気放出式の第２室内気循環冷房モード、第２室内気放出式の第１室内気循環冷房モード及び第１室内気放出式の第２室内気循環冷房モードの６種の冷房運転モードから１種の冷房運転モードを設定する通常運転モード設定処理を実行する。   When any one of the first chamber normal cooling operation, the second chamber normal cooling operation, and the both-chamber normal cooling operation is commanded by the operation changeover switch of the operation unit 10, the control unit 9 causes the outside air temperature sensor 41 and the first chamber to operate. The outside air temperature To, the first room temperature T1, the second room temperature T2, and the outside air humidity sensor 44, the first room humidity sensor 45, and the second room humidity detected by the temperature sensor 42 and the second room temperature sensor 43, respectively. Based on the outside air humidity Ho, the first room humidity H1, and the second room humidity H2 detected by the sensor 46, respectively, the first room air discharge type outside air intake cooling mode and the second room air discharge type outside air intake. Cooling mode, outside air discharge type first room air circulation cooling mode, outside air discharge type second room air circulation cooling mode, second room air discharge type first room air circulation cooling mode, and first room air discharge type first. 6 kinds of cooling operation mode of 2 indoor air circulation cooling mode Executing a normal operation mode setting process of setting a one cooling operation mode.

そして、制御部９は、冷房運転モードを通常運転モード設定処理にて設定したモードに設定すべく、運転モード切換手段Ｖの作動を制御すると共に、第１室通常冷房運転が指令された場合は、吹出口切換三方ダンパ２０を第１吹出状態に切り換え、第２室通常冷房運転が指令された場合は、吹出口切換三方ダンパ２０を第２吹出状態に切り換え、両室通常冷房運転が指令された場合は、吹出口切換三方ダンパ２０を両口吹出状態に切り換える。   And the control part 9 controls the action | operation of the operation mode switching means V to set the air_conditionaing | cooling operation mode to the mode set by the normal operation mode setting process, and when 1st chamber normal air_conditionaing | cooling operation is instruct | indicated. When the air outlet switching three-way damper 20 is switched to the first blowing state and the second chamber normal cooling operation is instructed, the air outlet switching three-way damper 20 is switched to the second air blowing state and the two-chamber normal cooling operation is instructed. If this occurs, the outlet switching three-way damper 20 is switched to the both-end outlet state.

図１１に示すフローチャートに基づいて、制御部９の通常運転モード設定処理における制御動作を説明する。
先ず、ステップ＃１で、外気温度Ｔｏ、第１室温度Ｔ１及び第２室温度Ｔ２のうち最低はどれかを判定して、第２室温度Ｔ２が最低と判定した場合は、ステップ＃２で、第１室湿度Ｈ１と外気湿度Ｈｏで低い方はどちらかを判定して、第１室湿度Ｈ１の方が低い場合は、ステップ＃３で冷房運転モードを第１室内気放出式の第２室内気循環冷房モードに設定し、外気湿度Ｈｏの方が低い場合は、ステップ＃４で、冷房運転モードを外気放出式の第２室内気循環冷房モードに設定する。 Based on the flowchart shown in FIG. 11, the control operation in the normal operation mode setting process of the control unit 9 will be described.
First, in step # 1, it is determined which of the outside air temperature To, the first chamber temperature T1, and the second chamber temperature T2 is the lowest, and if it is determined that the second chamber temperature T2 is the lowest, step # 2 The lower one of the first room humidity H1 and the outside air humidity Ho is determined. If the first room humidity H1 is lower, the cooling operation mode is changed to the first indoor air discharge type second in step # 3. When the room air circulation cooling mode is set and the outside air humidity Ho is lower, in step # 4, the cooling operation mode is set to the outside air discharge type second room air circulation cooling mode.

又、ステップ＃１で第１室温度Ｔ１が最低と判定した場合は、ステップ＃５で、第２室湿度Ｈ２と外気湿度Ｈｏで低い方はどちらかを判定して、第２室湿度Ｈ２の方が低い場合は、ステップ＃６で冷房運転モードを第２室内気放出式の第１室内気循環冷房モードに設定し、外気湿度Ｈｏの方が低い場合は、ステップ＃７で、冷房運転モードを外気放出式の第１室内気循環冷房モードに設定する。   If it is determined in step # 1 that the first chamber temperature T1 is the lowest, in step # 5, the lower one of the second chamber humidity H2 and the outside air humidity Ho is determined, and the second chamber humidity H2 is determined. If it is lower, the cooling operation mode is set to the second indoor air discharge type first indoor air circulation cooling mode in step # 6, and if the outside air humidity Ho is lower, the cooling operation mode is set in step # 7. Is set to the outside air discharge type first indoor air circulation cooling mode.

又、ステップ＃１で外気温度Ｔｏが最低と判定した場合は、ステップ＃８で、第１室湿度Ｈ１と第２室湿度Ｈ２で低い方はどちらかを判定して、第２室湿度Ｈ２の方が低い場合は、ステップ＃９で冷房運転モードを第２室内気放出式の外気取入冷房モードに設定し、第１室湿度Ｈ１の方が低い場合は、ステップ＃１０で、冷房運転モードを第１室内気放出式の外気取入冷房モードに設定する。   If it is determined in step # 1 that the outside air temperature To is the lowest, in step # 8, the lower one of the first chamber humidity H1 and the second chamber humidity H2 is determined, and the second chamber humidity H2 is determined. If it is lower, the cooling operation mode is set to the second indoor air discharge type outside air intake cooling mode in step # 9. If the first chamber humidity H1 is lower, the cooling operation mode is set in step # 10. Is set to the first indoor air discharge type outside air intake cooling mode.

つまり、外気温度Ｔｏ、第１室温度Ｔ１及び第２室温度Ｔ２のうちで第２室温度Ｔ２が最低である、即ち、第１空調対象室Ｒ１内の空気ＲＡ、第２空調対象室Ｒ２内の空気ＲＡ及び外気ＯＡのうちで第２空調対象室Ｒ２内の空気ＲＡが最低の場合は、冷房運転モードとしては、第２空調対象室Ｒ２内の空気ＲＡを冷却対象空気として用いる第１室内気放出式の第２室内気循環冷房モードと外気放出式の第２室内気循環冷房モードとの２種が設定対象になる。更に、それら２種の冷房運転モードは、気化用空気として一方が第１空調対象室Ｒ１内の空気ＲＡを用い、他方が外気ＯＡを用いるものであるので、第１空調対象室Ｒ１内の空気ＲＡと外気ＯＡのうち相対湿度が低い方が気化用空気として用いられる冷房運転モード、例えば、第１空調対象室Ｒ１内の空気ＲＡの方が相対湿度が低い場合は、第１室内気放出式の第２室内気循環冷房モードが運転対象のモードとして設定される。   That is, the second room temperature T2 is the lowest among the outside air temperature To, the first room temperature T1, and the second room temperature T2, that is, the air RA in the first air-conditioning target room R1 and the second air-conditioning target room R2. When the air RA in the second air-conditioning target room R2 is the lowest among the air RA and the outside air OA, as the cooling operation mode, the first room using the air RA in the second air-conditioning target room R2 as the cooling target air Two types, the air discharge type second indoor air circulation cooling mode and the outside air discharge type second indoor air circulation cooling mode, are set. Furthermore, in these two cooling operation modes, one uses the air RA in the first air-conditioning target room R1 and the other uses the outside air OA as the vaporizing air, so the air in the first air-conditioning target room R1. A cooling operation mode in which the lower relative humidity of RA and outside air OA is used as the vaporizing air, for example, when the relative humidity of the air RA in the first air-conditioning target room R1 is lower, the first indoor air discharge type The second indoor air circulation cooling mode is set as the operation target mode.

又、第１空調対象室Ｒ１内の空気ＲＡ、第２空調対象室Ｒ２内の空気ＲＡ及び外気ＯＡのうちで、温度が最低なのは第１空調対象室Ｒ１内の空気ＲＡの場合は、冷房運転モードとしては、第１空調対象室Ｒ１内の空気ＲＡを冷却対象空気として用いる第２室内気放出式の第１室内気循環冷房モードと外気放出式の第１室内気循環冷房モードとの２種が設定対象になる。更に、それら２種の冷房運転モードのうち、気化用空気として用いる空気の相対湿度が低い方の冷房運転モード、例えば、第２空調対象室Ｒ２内の空気ＲＡの方が相対湿度が低い場合は、第２室内気放出式の第１室内気循環冷房モードが運転対象のモードとして設定される。   Of the air RA in the first air-conditioning target room R1, the air RA in the second air-conditioning target room R2, and the outside air OA, the lowest temperature is the air RA in the first air-conditioning target room R1. There are two types of modes: a second indoor air discharge type first indoor air circulation cooling mode that uses the air RA in the first air conditioning target room R1 as cooling target air and an outside air discharge type first indoor air circulation cooling mode. Becomes the setting target. Furthermore, of these two types of cooling operation modes, the cooling operation mode in which the relative humidity of the air used as the vaporizing air is lower, for example, the air RA in the second air-conditioning target room R2 has a lower relative humidity. The first indoor air circulation cooling mode of the second indoor air discharge type is set as the operation target mode.

又、第１空調対象室Ｒ１内の空気ＲＡ、第２空調対象室Ｒ２内の空気ＲＡ及び外気ＯＡのうちで、温度が最低なのは外気ＯＡの場合は、冷房運転モードとしては、外気ＯＡを冷却対象空気として用いる第２室内気放出式の外気取入冷房モードと第１室内気放出式の外気取入冷房モードとの２種が設定対象になる。更に、それら２種の冷房運転モードのうち、気化用空気として用いる空気の相対湿度が低い方の冷房運転モード、例えば、第２空調対象室Ｒ２内の空気ＲＡの方が相対湿度が低い場合は、第２室内気放出式の外気取入冷房モードが運転対象のモードとして設定される。   Of the air RA in the first air-conditioning target room R1, the air RA in the second air-conditioning target room R2, and the outside air OA, when the temperature is the outside air OA, the outside air OA is cooled as the cooling operation mode. There are two types of setting targets: a second room air discharge type outside air intake cooling mode used as target air and a first room air discharge type outside air intake cooling mode. Furthermore, of these two types of cooling operation modes, the cooling operation mode in which the relative humidity of the air used as the vaporizing air is lower, for example, the air RA in the second air-conditioning target room R2 has a lower relative humidity. The second indoor air discharge type outside air intake cooling mode is set as the operation target mode.

つまり、この実施形態では、制御部９が、外気温度センサ４１、第１室温センサ４２及び第２室温センサ４３夫々の検出情報に基づいて、外気ＯＡ、第１空調対象室Ｒ１内の空気ＲＡ及び第２空調対象室Ｒ２内の空気ＲＡのうちで温度が最低の空気を冷却対象空気とする冷房運転モードに設定すべく、運転モード切換手段Ｖの作動を制御するように構成されていることになる。
更に、制御部９が、外気ＯＡ、第１空調対象室Ｒ１内の空気ＲＡ及び第２空調対象室Ｒ２内の空気ＲＡのうちで温度が最低の空気を冷却対象空気とする冷房運転モードが複数種ある場合は、外気湿度センサ４４、第１室湿度センサ４５及び第２室湿度センサ４６夫々の検出情報に基づいて、外気ＯＡ、第１空調対象室Ｒ１内の空気ＲＡ及び第２空調対象室Ｒ２内の空気ＲＡにおいて温度が最低の空気を除いたうちで、相対湿度が最低の空気を気化用空気とする冷房運転モードに設定すべく、運転モード切換手段Ｖの作動を制御するように構成されていることになる。 That is, in this embodiment, the control unit 9 determines the outside air OA, the air RA in the first air-conditioning target room R1 and the air RA in the first air-conditioning target room R1 based on the detection information of the outside temperature sensor 41, the first room temperature sensor 42, and the second room temperature sensor 43 The operation of the operation mode switching means V is controlled so as to set the cooling operation mode in which the air having the lowest temperature among the air RA in the second air conditioning target room R2 is the cooling target air. Become.
Further, the control unit 9 has a plurality of cooling operation modes in which the air having the lowest temperature among the outside air OA, the air RA in the first air conditioning target room R1 and the air RA in the second air conditioning target room R2 is the cooling target air. If there is a species, the outside air OA, the air RA in the first air-conditioning target room R1, and the second air-conditioning target room based on the detection information of the outside air humidity sensor 44, the first room humidity sensor 45, and the second room humidity sensor 46, respectively. The configuration is such that the operation of the operation mode switching means V is controlled so as to set the cooling operation mode in which the air having the lowest relative humidity is vaporized air, except for the air having the lowest temperature in the air RA in R2. Will be.

制御部９は、操作部１０の運転切換スイッチにより、第２室入浴後冷房運転が指令されると、外気温度センサ４１にて検出された外気温度Ｔｏ、第２室温度センサ４３にて検出された第２室温度Ｔ２に基づいて、運転モードを外気放出式の第２室内気循環冷房モードと第２室内気放出式の外気取入冷房モードとのいずれかに設定する入浴後運転モード設定処理を実行する。
制御部９は、入浴後運転モード設定処理では、外気温度Ｔｏと第２室温度Ｔ２で、第２室温度Ｔ２の方が低い場合は、運転モードを外気放出式の第２室内気循環冷房モードに設定し、外気温度Ｔｏの方が低い場合は、運転モードを第２室内気放出式の外気取入冷房モードに設定する。
そして、制御部９は、冷房運転モードを入浴後運転モード設定処理にて設定したモードに設定すべく、運転モード切換手段Ｖの作動を制御すると共に、吹出口切換三方ダンパ２０を第２吹出状態に切り換える。 When the cooling operation after bathing in the second chamber is commanded by the operation changeover switch of the operation unit 10, the control unit 9 detects the outside air temperature To detected by the outside air temperature sensor 41 and the second chamber temperature sensor 43. Based on the second chamber temperature T2, the after-bath operation mode setting process for setting the operation mode to either the outside air discharge type second indoor air circulation cooling mode or the second room air discharge type outside air intake cooling mode Execute.
In the operation mode setting process after bathing, the controller 9 sets the operation mode to the outside air discharge type second indoor air circulation cooling mode when the outside air temperature To and the second room temperature T2 are lower than the second room temperature T2. When the outdoor air temperature To is lower, the operation mode is set to the second indoor air discharge type outdoor air intake cooling mode.
And the control part 9 controls the action | operation of the operation mode switching means V, and sets the blower outlet switching three-way damper 20 to a 2nd blowing state so that the air_conditionaing | cooling operation mode may be set to the mode set by the operation mode setting process after bathing. Switch to.

制御部９は、操作部１０の運転切換スイッチにより、第１室入浴中冷房運転が指令されると、外気温度センサ４１にて検出された外気温度Ｔｏ、第２室温度センサ４３にて検出された第２室温度Ｔ２に基づいて、運転モードを外気放出式の第２室内気循環冷房モードと第２室内気放出式の外気取入冷房モードとのいずれかに設定する入浴中運転モード設定処理を実行する。
制御部９は、入浴中運転モード設定処理では、外気温度Ｔｏと第２室温度Ｔ２で、第２室温度Ｔ２の方が低い場合は、運転モードを外気放出式の第２室内気循環冷房モードに設定し、外気温度Ｔｏの方が低い場合は、運転モードを第２室内気放出式の外気取入冷房モードに設定する。
そして、制御部９は、冷房運転モードを入浴中運転モード設定処理にて設定したモードに設定すべく、運転モード切換手段Ｖの作動を制御すると共に、吹出口切換三方ダンパ２０を第１吹出状態に切り換える。 When the operation switching switch of the operation unit 10 instructs the cooling operation during bathing in the first chamber, the control unit 9 detects the outside air temperature To detected by the outside air temperature sensor 41 and the second chamber temperature sensor 43. Based on the second chamber temperature T2, the operation mode setting process during bathing is performed to set the operation mode to either the outside air discharge type second indoor air circulation cooling mode or the second room air discharge type outside air intake cooling mode. Execute.
In the bathing operation mode setting process, the controller 9 sets the operation mode to the outside air discharge type second indoor air circulation cooling mode when the outside air temperature To and the second room temperature T2 are lower than the second room temperature T2. When the outdoor air temperature To is lower, the operation mode is set to the second indoor air discharge type outdoor air intake cooling mode.
And the control part 9 controls the action | operation of the operation mode switching means V, and sets the blower outlet switching three-way damper 20 to the 1st blowing state so that the cooling operation mode may be set to the mode set in the bathing operation mode setting process. Switch to.

つまり、第１空調対象室Ｒ１を入浴で使用している間やその直後は、第１空調対象室Ｒ１内の空気ＲＡは、高温高湿であるので、冷却対象空気や気化用空気としては適さない。
そこで、第１室入浴中冷房運転や第２室入浴後冷房運転の冷房運転モードとしては、冷却対象空気として第２空調対象室Ｒ２内の空気ＲＡや外気ＯＡを用いる外気放出式の第２室内気循環冷房モードや第２室内気放出式の外気取入冷房モードが設定対象となり、それらの運転モードのうちで、冷却対象空気として用いる空気の温度が低い方、例えば、第２空調対象室Ｒ２内の空気ＲＡの方が温度が低い場合は、外気放出式の第２室内気循環冷房モードが運転対象のモードとして設定される。 That is, while the first air-conditioning target room R1 is used for bathing or immediately after that, the air RA in the first air-conditioning target room R1 is high-temperature and high-humidity, and is therefore suitable as cooling target air or vaporizing air. Absent.
Therefore, as the cooling operation mode of the cooling operation during bathing in the first chamber or the cooling operation after bathing in the second chamber, the second room of the outside air discharge type using the air RA or the outside air OA in the second air conditioning target room R2 as the cooling target air. The air circulation cooling mode and the second indoor air discharge type outside air intake cooling mode are set, and among those operation modes, the one where the temperature of the air used as the cooling target air is lower, for example, the second air conditioning target room R2 When the temperature of the inner air RA is lower, the outside air discharge type second indoor air circulation cooling mode is set as the operation target mode.

制御部９は、操作部１０の運転切換スイッチにより、換気運転が指令されると、図８及び図１０に示すように、室内気用途切換三方ダンパ３１を室内気放出状態に、外気用途切換三方ダンパ２９を外気給気状態に、副吸込口切換三方ダンパ２８を遮断状態に、給水断続弁１４を閉じ状態に、循環遮断ダンパ３７を閉じ状態に夫々切り換えると共に、給気ファン１及び排気ファン２を作動させる。
並びに、制御部９は、換気運転モード選択スイッチによる指令に基づき、指令された換気運転モードに設定すべく、主吸込口切換三方ダンパ２４及び吹出口切換三方ダンパ２０夫々の作動を制御する。例えば、両室換気モードが指令されている場合は、図８及び図１０に示すように、主吸込口切換三方ダンパ２４を両口吸込状態に、吹出口切換三方ダンパ２０を両口吹出状態に夫々切り換える。 When the ventilation operation is instructed by the operation changeover switch of the operation unit 10, the control unit 9 sets the indoor air use switching three-way damper 31 to the indoor air discharge state, as shown in FIGS. The damper 29 is switched to the outside air supply state, the auxiliary suction switching three-way damper 28 is switched to the shut-off state, the water supply intermittent valve 14 is switched to the closed state, and the circulation shut-off damper 37 is switched to the closed state. Is activated.
In addition, the control unit 9 controls the operation of the main inlet switching three-way damper 24 and the outlet switching three-way damper 20 to set the commanded ventilation operation mode based on the command from the ventilation operation mode selection switch. For example, when the both-chamber ventilation mode is commanded, as shown in FIGS. 8 and 10, the main suction port switching three-way damper 24 is set to the both-port suction state, and the outlet switching three-way damper 20 is set to the both-port blowing state. Switch each one.

例えば、両室換気モードにて換気運転が実行されると、図８に示すように、第１空調対象室Ｒ１及び第２空調対象室Ｒ２の両室の空気ＲＡが排気口４から排出されると共に、外気ＯＡが第１吹出口５及び第２吹出口７から送出されて、第１空調対象室Ｒ１及び第２空調対象室Ｒ２が換気される。   For example, when the ventilation operation is executed in the both-chamber ventilation mode, the air RA in both the first air-conditioning target room R1 and the second air-conditioning target room R2 is discharged from the exhaust port 4 as shown in FIG. At the same time, the outside air OA is sent out from the first outlet 5 and the second outlet 7, and the first air-conditioning target room R1 and the second air-conditioning target room R2 are ventilated.

制御部９は、操作部１０の運転切換スイッチにより、暖房乾燥運転が指令されると、図９及び図１０に示すように、循環遮断ダンパ３７を開き状態に、主吸込口切換三方ダンパ２４を第１室吸込状態に、室内気用途切換三方ダンパ３１を室内気放出状態に、外気用途切換三方ダンパ２９を遮断状態に、副吸込口切換三方ダンパ２８を遮断状態に、給水断続弁１４を閉じ状態に夫々切り換え、循環ファン３６及び排気ファン２を作動させ、暖房用加熱手段を加熱作動させる。但し、排気ファン２は、その送風量が各種の冷房運転時や換気運転時よりも少なく、しかも、循環ファン３６の送風量よりも少なくなるように回転速度が調整される。
並びに、制御部９は、暖房乾燥モード切り換えスイッチにより、両室暖房乾燥モードが指令されている場合は、図９及び図１０に示すように、吹出口切換三方ダンパ２０を両口吹出状態に夫々切り換え、第１室暖房乾燥モードが指令されている場合は、図示を省略するが、吹出口切換三方ダンパ２０を第２室吹出状態に切り換える。 When the heating / drying operation is commanded by the operation switch of the operation unit 10, the control unit 9 opens the circulation cutoff damper 37 and opens the main suction port switching three-way damper 24 as shown in FIGS. 9 and 10. In the first chamber suction state, the room air use switching three-way damper 31 is set in the room air discharge state, the outside air use switching three-way damper 29 is shut off, the auxiliary suction switching three-way damper 28 is shut off, and the water supply intermittent valve 14 is closed. The state is switched to each state, the circulation fan 36 and the exhaust fan 2 are operated, and the heating means for heating is heated. However, the rotational speed of the exhaust fan 2 is adjusted so that the amount of air blown is smaller than that during various cooling operations and ventilation operations, and is smaller than the amount of air blown by the circulation fan 36.
In addition, when the both-chamber heating / drying mode is commanded by the heating / drying mode switching switch, the control unit 9 puts the outlet switching three-way damper 20 into the both-mouthed blowing state as shown in FIGS. When switching and the first room heating / drying mode are instructed, although not shown, the outlet switching three-way damper 20 is switched to the second chamber blowing state.

例えば、両室暖房乾燥モードにて暖房乾燥運転が実行されると、図９に示すように、第１空調対象室Ｒ１内の空気が第１吸込口６から吸い込まれて、その一部が排気口４から排気されつつ、残部が暖房加熱手段により加熱された後、第１吹出口５及び第２吹出口７から送出されることになり、第１空調対象室Ｒ１内の温度が上昇すると共に、相対湿度が低下し、並びに、第２空調対象室Ｒ２内の温度が上昇する。   For example, when the heating / drying operation is executed in the both-chamber heating / drying mode, as shown in FIG. 9, the air in the first air-conditioning target room R <b> 1 is sucked from the first suction port 6, and a part thereof is exhausted. While the remainder is heated by the heating and heating means while being exhausted from the opening 4, it is sent out from the first outlet 5 and the second outlet 7, and the temperature in the first air-conditioning target room R <b> 1 rises. The relative humidity decreases, and the temperature in the second air-conditioning target room R2 increases.

暖房運転における制御動作は、主吸込口切換三方ダンパ２４を第２室吸込状態に切り換える以外は、上記の暖房乾燥運転時の制御動作と同様であるので、説明及び図示を省略する。
例えば、両室暖房モードにて暖房モードが実行されると、第１空調対象室Ｒ１内の空気が第１吸込口６から吸い込まれて、暖房加熱手段により加熱された後、第１吹出口５及び第２吹出口７から送出されることになり、第１空調対象室Ｒ１及び第２空調対象室Ｒ２両室内の温度が上昇する。 Since the control operation in the heating operation is the same as the control operation in the heating / drying operation described above except that the main suction port switching three-way damper 24 is switched to the second chamber suction state, description and illustration are omitted.
For example, when the heating mode is executed in the both-chamber heating mode, after the air in the first air-conditioning target room R1 is sucked from the first suction port 6 and heated by the heating heating means, the first outlet 5 And it will be sent out from the 2nd blower outlet 7, and temperature in both 1st air-conditioning object room R1 and 2nd air-conditioning object room R2 room rises.
