Description

本発明は、空気調和装置に関し、特に、室内空気の顕熱処理と潜熱処理を別々に行えるようにした空気調和装置に関するものである。   The present invention relates to an air conditioner, and more particularly to an air conditioner that can perform sensible heat treatment and latent heat treatment of room air separately.

従来より、室内空気の顕熱処理と潜熱処理を別々に行うことのできる空気調和装置（空気調和システム）として、蒸気圧縮式冷凍サイクルにより主に空気の顕熱処理を行うとともに、空気中の水分を吸着／脱着可能な吸着剤により空気の潜熱処理を行うようにしたものがある（例えば、特許文献１参照）。この空気調和システムでは、室内で空気を循環させて顕熱処理をする空調機と、室外空気の湿度を調節して室内に供給することで潜熱処理をするデシカント外調機とを備えている。   Conventionally, as an air conditioner (air conditioning system) that can separately perform sensible heat treatment and latent heat treatment of indoor air, it mainly performs sensible heat treatment of air with a vapor compression refrigeration cycle and adsorbs moisture in the air / There is one in which a latent heat treatment of air is performed using a desorbable adsorbent (see, for example, Patent Document 1). This air conditioning system includes an air conditioner that performs sensible heat treatment by circulating air in a room, and a desiccant air conditioner that performs latent heat treatment by adjusting the humidity of the outdoor air and supplying it to the room.

上記デシカント外調機では、空気中の水分を吸着剤で吸着する吸湿動作と、吸着剤に吸着された水分を空気に放出する放湿動作とが交互に行われ、吸湿動作時には空気が減湿され、放湿動作時には空気が加湿される。そして、冷房運転時には室外空気を吸湿動作によって減湿して室内に供給し、暖房運転時には室外空気を放湿動作によって加湿して室内に供給するようにしている。   In the desiccant air conditioner described above, the moisture absorption operation that adsorbs moisture in the air with the adsorbent and the moisture release operation that releases the moisture adsorbed on the adsorbent to the air are performed alternately, and the air is dehumidified during the moisture absorption operation. The air is humidified during the moisture release operation. During the cooling operation, the outdoor air is dehumidified by the moisture absorption operation and supplied to the room, and during the heating operation, the outdoor air is humidified by the moisture release operation and supplied to the room.

この従来のシステムでは、空調機とデシカント外調機が別々に設置されるため、大きな設置スペースが必要であり、コストも高くなりがちである。これに対し、空調機とデシカント外調機とを１つのケーシング内に収納して一体化することで１カ所に設置することは可能であるが、その場合でも装置が大型になることは避けられず、しかも構成が複雑になりやすい問題もある。   In this conventional system, since the air conditioner and the desiccant air conditioner are separately installed, a large installation space is required and the cost tends to be high. On the other hand, it is possible to install the air conditioner and the desiccant air conditioner in one casing by integrating them in one casing, but even in that case, the apparatus cannot be increased in size. In addition, there is a problem that the configuration tends to be complicated.

また、デシカント外調機には吸着剤を再生するための加熱手段が必要であり、上記公報のシステムでは、その加熱手段としてヒートポンプ装置を用いている。このため、従来の構成では、空調機の蒸気圧縮式冷凍サイクルとデシカント外調機のヒートポンプ装置とをそれぞれ別個に駆動することが必要であるために、ＣＯＰ（成績係数）が低下するおそれがある。   In addition, the desiccant air conditioner requires a heating means for regenerating the adsorbent, and the system disclosed in the above publication uses a heat pump device as the heating means. For this reason, in the conventional configuration, it is necessary to separately drive the vapor compression refrigeration cycle of the air conditioner and the heat pump device of the desiccant external air conditioner, so that the COP (coefficient of performance) may be reduced. .

そこで、このような問題を解決するために、空気調和装置の冷媒回路に用いる熱交換器の少なくとも１つに、表面に吸着剤を担持した熱交換器（吸着熱交換器という）を用いることが考えられる。このようにすると、冷媒回路を駆動するだけで、室内空気の潜熱処理及び顕熱処理を行えるうえに吸着剤を再生することもできるため、吸着剤の再生専用の加熱手段が不要となり、ＣＯＰに優れた運転が可能となる。また、冷媒回路だけで空気調和装置を構成できるので、装置をコンパクトに構成することも可能となる。
特開平０９−３１８１２６号公報 Therefore, in order to solve such problems, it is necessary to use a heat exchanger (adsorption heat exchanger) carrying an adsorbent on the surface as at least one of the heat exchangers used in the refrigerant circuit of the air conditioner. Conceivable. In this way, the latent air heat treatment and sensible heat treatment of the indoor air can be performed and the adsorbent can be regenerated only by driving the refrigerant circuit, so that there is no need for a heating means dedicated to regenerating the adsorbent, and the COP is excellent Operation is possible. Moreover, since an air conditioning apparatus can be comprised only with a refrigerant circuit, it also becomes possible to comprise an apparatus compactly.

吸着熱交換器を用いる場合、上記吸着剤は、冷媒が蒸発する際に冷媒に吸熱されて冷却され、この冷却時に室内空気または室外空気の水分を吸着する。また、上記吸着剤は、冷媒が凝縮する際に冷媒が放熱することにより加熱され、この加熱時に水分を室内空気または室外空気へ放出する。   In the case of using an adsorption heat exchanger, the adsorbent is cooled by being absorbed by the refrigerant when the refrigerant evaporates, and adsorbs moisture in indoor air or outdoor air during this cooling. The adsorbent is heated by the heat dissipation of the refrigerant when the refrigerant condenses, and moisture is released into the indoor air or the outdoor air during the heating.

しかし、上記構成では、吸着剤による水分の吸着と同時に空気の冷却が行われるとともに、吸着剤からの水分の放出と同時に空気の加熱が行われるため、吸着剤による吸脱着効果が損なわれるおそれがある。また、その場合、吸着剤における水分の吸着量や再生量が不十分になって、空気調和装置の除湿能力や加湿能力が低下してしまうおそれがある。   However, in the above configuration, air is cooled simultaneously with the adsorption of moisture by the adsorbent, and air is heated simultaneously with the release of moisture from the adsorbent, which may impair the adsorption / desorption effect by the adsorbent. is there. In that case, the amount of moisture adsorbed and regenerated in the adsorbent may be insufficient, and the dehumidifying ability and humidifying ability of the air conditioner may be reduced.

Further, during the moisture release operation, the adsorbent is regenerated by releasing moisture to the air flowing through the adsorption heat exchanger (13, 14) while heating the adsorbent with the adsorption heat exchanger (13, 14). The Then, the control means (15) alternately performs the moisture absorption operation and the moisture release operation.

第１４の発明は、第１３の発明の空気調和装置において、制御手段(15)には、吸湿動作と放湿動作を切り換える時間間隔を潜熱負荷に応じて設定する切換間隔設定手段(16)が設けられていることを特徴としている。   According to a fourteenth aspect, in the air conditioner according to the thirteenth aspect, the control means (15) includes a switching interval setting means (16) for setting a time interval for switching between the moisture absorption operation and the moisture release operation according to the latent heat load.

It is characterized by being composed.

これらの第１４，第１５の発明では、吸着剤による水分の吸着量や放出量が、それぞれの運転開始直後は多く、時間が経つにつれて徐々に少なくなることから、室内の潜熱負荷が大きいときは切換頻度を多くすることで除湿量または加湿量を多くし、潜熱負荷が小さいときは切換頻度を少なくすることで除湿量または加湿量を少なくすることができる。つまり、潜熱負荷に見合った運転を確実に行うことが可能となる。   In these fourteenth and fifteenth inventions, the amount of moisture adsorbed and released by the adsorbent is large immediately after the start of each operation, and gradually decreases with time. Therefore, when the latent heat load in the room is large, By increasing the switching frequency, the dehumidifying amount or humidifying amount can be increased, and when the latent heat load is small, the dehumidifying amount or humidifying amount can be decreased by decreasing the switching frequency. That is, it is possible to reliably perform the operation corresponding to the latent heat load.

上記第１の発明によれば、第１空気と第２空気とが熱交換を行う熱交換素子(50)を設けて、吸着用空気または再生用空気がこの熱交換素子(50)を通過するようにしたことにより、該熱交換素子(50)で吸着用空気の冷却または再生用空気の加熱を行えるようにしている。したがって、吸着熱交換器(13,14) での空気の除湿または加湿を効率よく行うことができるので、除湿能力または加湿能力が低下するのを防止できる。   According to the first aspect of the present invention, the heat exchange element (50) for exchanging heat between the first air and the second air is provided, and the adsorption air or the regeneration air passes through the heat exchange element (50). By doing so, the heat exchange element (50) can cool the adsorption air or heat the regeneration air. Therefore, air can be dehumidified or humidified efficiently in the adsorption heat exchanger (13, 14), so that it is possible to prevent the dehumidifying ability or the humidifying ability from being lowered.

上記第２の発明によれば、熱交換素子(50)を通過する第１空気を吸着熱交換器(13,14) を通過する前の吸着用空気とし、該熱交換素子(50)を通過する第２空気を吸着用空気を冷却する冷却用空気としたことにより、吸着用空気を熱交換素子(50)で冷却できるようにしている。したがって、吸着熱交換器(13,14) での空気の除湿を効率よく行うことができるので、除湿能力が低下するのを防止できる。   According to the second aspect of the invention, the first air passing through the heat exchange element (50) is used as adsorption air before passing through the adsorption heat exchanger (13, 14), and passes through the heat exchange element (50). Since the second air to be used is cooling air for cooling the adsorption air, the adsorption air can be cooled by the heat exchange element (50). Therefore, since the dehumidification of the air can be performed efficiently in the adsorption heat exchanger (13, 14), it is possible to prevent the dehumidification capacity from being lowered.

上記第３の発明によれば、熱交換素子(50)を通過する第２空気を吸着熱交換器(13,14) を通過する前の再生用空気とし、該熱交換素子(50)を通過する第１空気を再生用空気を加熱する加熱用空気としたことにより、再生用空気を熱交換素子(50)で加熱できるようにしている。したがって、吸着熱交換器(13,14) での空気の加湿を効率よく行うことができるので、加湿能力が低下するのを防止できる。   According to the third aspect of the invention, the second air passing through the heat exchange element (50) is used as regeneration air before passing through the adsorption heat exchanger (13, 14), and passes through the heat exchange element (50). Since the first air to be used is heating air for heating the regeneration air, the regeneration air can be heated by the heat exchange element (50). Therefore, since the humidification of the air in the adsorption heat exchanger (13, 14) can be performed efficiently, it is possible to prevent the humidification capacity from being lowered.

上記第４の発明によれば、熱交換素子(50)を通過する第１空気を吸着熱交換器(13,14) を通過する前の吸着用空気とし、該熱交換素子(50)を通過する第２空気を該吸着熱交換器(13,14) を通過する前の再生用空気として、該熱交換素子(50)で吸着用空気が冷却されるとともに再生用空気が加熱されるようにしている。このことにより、吸着用空気を熱交換素子(50)で再生用空気により冷却することができるので、吸着熱交換器(13,14) での空気の除湿を効率よく行うことで除湿能力を高めることができるとともに、再生用空気を熱交換素子(50)で吸着用空気により加熱することができるので、吸着熱交換器(13,14) での空気の加湿を効率よく行うことで加湿能力を高めることができる。   According to the fourth aspect of the invention, the first air passing through the heat exchange element (50) is used as adsorption air before passing through the adsorption heat exchanger (13, 14), and passes through the heat exchange element (50). As the second air to be regenerated before passing through the adsorption heat exchanger (13, 14), the heat exchange element (50) cools the adsorption air and heats the regeneration air. ing. As a result, the adsorption air can be cooled by the regeneration air by the heat exchange element (50), so that the dehumidification capability is improved by efficiently dehumidifying the air in the adsorption heat exchanger (13, 14). In addition, since the regeneration air can be heated by the adsorption air by the heat exchange element (50), the humidification capacity can be improved by efficiently humidifying the air in the adsorption heat exchanger (13, 14). Can be increased.

上記第５の発明によれば、第１空気と第２空気とをいわゆる直交流式の顕熱交換器によって熱交換させることができる。この直交流式の顕熱交換器は、比較的安価であり、ランニングコストも安価であるため、熱交換素子(50)に要するコストを削減することができる。   According to the fifth aspect of the present invention, the first air and the second air can be heat exchanged by the so-called cross-flow sensible heat exchanger. Since this cross flow type sensible heat exchanger is relatively inexpensive and has a low running cost, the cost required for the heat exchange element (50) can be reduced.

上記第６の発明によれば、第１空気と第２空気とを回転式の顕熱交換器によって熱交換させることができる。この回転式の顕熱交換器は、回転速度を変化させることで、第１空気と第２空気との熱交換率を変更することができる。このため、第１空気または第２空気の温度調節を行うことができ、吸着剤における水分の吸着量、あるいは吸着剤における水分の放出量を調整することができる。したがって、この空気調和装置の湿度調整を細かく行うことができる。   According to the sixth aspect, heat can be exchanged between the first air and the second air by the rotary sensible heat exchanger. This rotary sensible heat exchanger can change the heat exchange rate between the first air and the second air by changing the rotation speed. For this reason, the temperature of the first air or the second air can be adjusted, and the amount of moisture adsorbed in the adsorbent or the amount of moisture released in the adsorbent can be adjusted. Therefore, the humidity of the air conditioner can be finely adjusted.

上記第７の発明によれば、第１空気と第２空気とを全熱交換器によって熱交換させることができる。この全熱交換器は、第１空気と第２空気の潜熱交換を行うことができる。このため、第１空気の湿度が第２空気の湿度より高い場合、全熱交換器によって第１空気の水分が第２空気へ奪われる。したがって、この第１空気を除湿時に室内へ給気する場合、この空気調和装置の除湿能力を高めることができる。また、第１空気の湿度が第２空気の湿度より低い場合、全熱交換器によって第２空気の水分が第１空気へ付与される。したがって、この第１空気を加湿時に室内へ給気する場合、この空気調和装置の加湿能力を高めることができる。   According to the seventh aspect, the first air and the second air can be heat exchanged by the total heat exchanger. This total heat exchanger can perform latent heat exchange between the first air and the second air. For this reason, when the humidity of 1st air is higher than the humidity of 2nd air, the water | moisture content of 1st air is taken to 2nd air by a total heat exchanger. Therefore, when the first air is supplied into the room at the time of dehumidification, the dehumidifying ability of the air conditioner can be increased. Moreover, when the humidity of 1st air is lower than the humidity of 2nd air, the water | moisture content of 2nd air is provided to 1st air with a total heat exchanger. Therefore, when this 1st air is supplied indoors at the time of humidification, the humidification capability of this air conditioning apparatus can be improved.

Can be performed automatically. In the present invention, since only three heat exchangers (11, 13, 14) are required, the apparatus configuration can be simplified.

Can be performed continuously. Furthermore, the amount of latent heat treatment can be increased by using both an air heat exchanger (11, 12) for performing sensible heat treatment and an adsorption heat exchanger (13, 14) for performing latent heat treatment, both during cooling and dehumidification. It is possible to freely control the amount of heat treatment and sensible heat treatment, which can enhance indoor comfort.

上記第１０の発明によれば、熱媒体回路(20,40) として蒸気圧縮式冷凍サイクルを行う冷媒回路(20)を用いることにより、室内の潜熱負荷と顕熱負荷を処理することができる。また、吸着剤を再生するのに冷媒回路(20)以外の専用の加熱手段は不要であるため、装置構成が複雑になることも防止できる。   According to the tenth aspect, by using the refrigerant circuit (20) that performs the vapor compression refrigeration cycle as the heat medium circuit (20, 40), the indoor latent heat load and sensible heat load can be processed. In addition, since no dedicated heating means other than the refrigerant circuit (20) is required to regenerate the adsorbent, it is possible to prevent the apparatus configuration from becoming complicated.

上記第１１の発明によれば、熱媒体回路(20,40) として冷温水が循環する冷温水回路(40)を用いることにより、室内の潜熱負荷と顕熱負荷を処理することができる。また、吸着剤を再生するのに冷温水回路(40)以外の専用の加熱手段は不要であるため、装置構成が複雑になることも防止できる。   According to the eleventh aspect, by using the cold / hot water circuit (40) in which the cold / hot water circulates as the heat medium circuit (20, 40), the indoor latent heat load and sensible heat load can be processed. Further, since a dedicated heating means other than the cold / hot water circuit (40) is not required to regenerate the adsorbent, it is possible to prevent the apparatus configuration from becoming complicated.

上記第１２の発明によれば、熱媒体回路(20,40) として冷媒回路(20)と冷温水回路(40)を用いることにより、室内の潜熱負荷と顕熱負荷を処理することができる。また、吸着剤を再生するのに冷媒回路(20)及び冷温水回路(40)以外の専用の加熱手段は不要であるため、装置構成が複雑になることも防止できる。   According to the twelfth aspect of the invention, by using the refrigerant circuit (20) and the cold / hot water circuit (40) as the heat medium circuit (20, 40), the indoor latent heat load and sensible heat load can be processed.

In particular, according to the fifteenth aspect, the latent heat load is reduced. The larger the value is, the smaller the setting value of the time interval for switching between the moisture absorption operation and the moisture release operation is.

(Cooling dehumidification operation)
During the cooling and dehumidifying operation, the first four-way switching valve (25) is switched to the first state, and the first operation in FIG. 1 (A) and the second operation in FIG. 1 (B) are alternately performed. The second four-way switching valve (26) is switched to the first state during the first operation, and the second four-way switching valve (26) is switched to the second state during the second operation. In both the first operation and the second operation, the expansion valve (23) is throttled to a predetermined opening.

この状態において、第１運転時、圧縮機(21)から吐出された冷媒は、空気熱交換器(11)と第１吸着熱交換器(13)で凝縮した後、膨張弁(23)で膨張し、第２吸着熱交換器(14)で蒸発して圧縮機(21)に吸入される。   In this state, the refrigerant discharged from the compressor (21) during the first operation is condensed by the air heat exchanger (11) and the first adsorption heat exchanger (13), and then expanded by the expansion valve (23). Then, it is evaporated by the second adsorption heat exchanger (14) and sucked into the compressor (21).

その際、第２吸着熱交換器(14)において室内の潜熱処理と顕熱処理が行われる。つまり、第２吸着熱交換器(14)を通過する室内空気(RA)は、まず、水分が吸着剤に吸着されることで減湿（潜熱処理）されてから徐々に冷却（顕熱処理）され、室内に戻る。   At that time, an indoor latent heat treatment and a sensible heat treatment are performed in the second adsorption heat exchanger (14). That is, the indoor air (RA) passing through the second adsorption heat exchanger (14) is first dehumidified (latent heat treatment) by moisture adsorbed by the adsorbent and then gradually cooled (sensible heat treatment). Return to the room.

一方、上記熱交換素子(50)では、温度の高い室外空気（第１空気）(OA)と温度の低い室内空気（第２空気）(RA)とが熱交換をすることにより、室内空気(RA)が加熱され、室外空気(OA)が冷却される。室内空気(RA)は、熱交換素子(50)で加熱された後に第１吸着熱交換器(13)を通過し、該第１吸着熱交換器(13)の吸着剤を再生してから排出空気(EA)として室外に排出される。また、室外空気(OA)は、上記熱交換素子(50)を通過した後、空気熱交換器(11)を通過する際に冷媒と熱交換し、排出空気(EA)として室外に排出される。   On the other hand, in the heat exchange element (50), the outdoor air (first air) (OA) having a high temperature and the indoor air (second air) (RA) having a low temperature exchange heat to thereby generate indoor air ( RA) is heated and outdoor air (OA) is cooled. The indoor air (RA) is heated by the heat exchange element (50), passes through the first adsorption heat exchanger (13), regenerates the adsorbent in the first adsorption heat exchanger (13), and then discharged. It is discharged outside as air (EA). In addition, after passing through the heat exchange element (50), the outdoor air (OA) exchanges heat with the refrigerant when passing through the air heat exchanger (11), and is discharged outside as outdoor air (EA). .

また、第２運転時、圧縮機(21)から吐出された冷媒は、空気熱交換器(11)と第２吸着熱交換器(14)で凝縮した後、膨張弁(23)で膨張し、第１吸着熱交換器(13)で蒸発して圧縮機(21)に吸入される。   In the second operation, the refrigerant discharged from the compressor (21) is condensed by the air heat exchanger (11) and the second adsorption heat exchanger (14), and then expanded by the expansion valve (23).

That is, the indoor air (RA) passing through the first adsorption heat exchanger (13) is first dehumidified (latent heat treatment) by moisture adsorbed by the adsorbent and then gradually cooled (sensible heat treatment). Return to the room.

一方、上記熱交換素子(50)では、温度の高い室外空気（第１空気）(OA)と温度の低い室内空気（第２空気）(RA)とが熱交換をすることにより、室内空気(RA)が加熱され、室外空気(OA)が冷却される。室内空気(RA)は、熱交換素子(50)で加熱された後に第２吸着熱交換器(14)を通過し、該第２吸着熱交換器(14)の吸着剤を再生してから排出空気(EA)として室外に排出される。また、室外空気(OA)は、上記熱交換素子(50)を通過した後、空気熱交換器(11)を通過する際に冷媒と熱交換し、排出空気(EA)として室外に排出される。   On the other hand, in the heat exchange element (50), the outdoor air (first air) (OA) having a high temperature and the indoor air (second air) (RA) having a low temperature exchange heat to thereby generate indoor air ( RA) is heated and outdoor air (OA) is cooled.

It is discharged outside as air (EA). In addition, after passing through the heat exchange element (50), the outdoor air (OA) exchanges heat with the refrigerant when passing through the air heat exchanger (11), and is discharged outside as outdoor air (EA). .

以上のようにして第１運転と第２運転とを交互に繰り返すことにより、室内の顕熱負荷を連続的に処理しながら、室内の潜熱負荷も連続的に処理できる。その際、第１運転と第２運転は、上記コントローラ(15)により、室内の潜熱負荷が大きくなるほど短い時間間隔で切り換えられる。これにより、室内の潜熱負荷が大きいときは切換頻度を多くすることで除湿量を多くして、室内の快適性を高めることができる。また、逆に室内の潜熱負荷が小さいときは、切換頻度を少なくすることで除湿量を少なくして、省エネ性を高められる。   By alternately repeating the first operation and the second operation as described above, the indoor latent heat load can be continuously processed while the indoor sensible heat load is continuously processed. At that time, the first operation and the second operation are switched by the controller (15) at shorter time intervals as the indoor latent heat load increases. Thus, when the indoor latent heat load is large, the dehumidification amount can be increased by increasing the switching frequency, and the indoor comfort can be enhanced. Conversely, when the latent heat load in the room is small, the dehumidification amount can be reduced by reducing the switching frequency, and the energy saving performance can be improved.

−運転動作−
次に、この空気調和装置(10)の運転動作について説明する。 -Driving action-
Next, the operation of the air conditioner (10) will be described.

（冷房除湿運転）
冷房除湿運転時、第１四路切換弁(25)は第１の状態に切り換わり、図３（Ａ）の第１運転と図３（Ｂ）の第２運転とを交互に行う。そして、第１運転時は第２四路切換弁(26)が第１の状態に切り換わり、第２運転時は第２四路切換弁(26)が第２の状態に切り換わる。また、第１運転時と第２運転時のいずれも、膨張弁(23)は所定開度に絞られる。 (Cooling dehumidification operation)
During the cooling and dehumidifying operation, the first four-way switching valve (25) is switched to the first state, and the first operation in FIG. 3 (A) and the second operation in FIG. 3 (B) are alternately performed. The second four-way switching valve (26) is switched to the first state during the first operation, and the second four-way switching valve (26) is switched to the second state during the second operation. In both the first operation and the second operation, the expansion valve (23) is throttled to a predetermined opening.

この状態において、第１運転時、圧縮機(21)から吐出された冷媒は、第１空気熱交換器(11)と第１吸着熱交換器(13)とで凝縮した後、膨張弁(23)で膨張し、第２吸着熱交換器(14)と第２空気熱交換器(12)とで蒸発して圧縮機(21)に吸入される。   In this state, the refrigerant discharged from the compressor (21) during the first operation is condensed by the first air heat exchanger (11) and the first adsorption heat exchanger (13), and then the expansion valve (23 ), Evaporates in the second adsorption heat exchanger (14) and the second air heat exchanger (12), and is sucked into the compressor (21).

その際、第２吸着熱交換器(14)において室内の潜熱処理が行われ、第２空気熱交換器(12)において室内の顕熱処理が行われる。つまり、室内空気(RA)は、一部が第２吸着熱交換器(14)を通過する際に水分が吸着剤に吸着されることで減湿（潜熱処理）されて室内に戻り、他の一部が第２空気熱交換器(12)を通過する際に冷却（顕熱処理）されて室内に戻る。こうすることにより、室内の冷房と除湿を効率よく行うことができる。   At that time, an indoor latent heat treatment is performed in the second adsorption heat exchanger (14), and an indoor sensible heat treatment is performed in the second air heat exchanger (12). In other words, when part of the room air (RA) passes through the second adsorption heat exchanger (14), the moisture is adsorbed by the adsorbent and dehumidified (latent heat treatment) to return to the room. When a part passes through the second air heat exchanger (12), it is cooled (sensible heat treatment) and returned to the room. By doing so, indoor cooling and dehumidification can be performed efficiently.

一方、上記熱交換素子(50)では、温度の高い室外空気（第１空気）(OA)と温度の低い室内空気（第２空気）(RA)とが熱交換をすることにより、室内空気(RA)が加熱され、室外空気(OA)が冷却される。第２空気である室内空気(RA)は、熱交換素子(50)で加熱された後に第１吸着熱交換器(13)を通過し、該第１吸着熱交換器(13)の吸着剤を再生してから排出空気(EA)として室外に排出される。また、室外空気(OA)は、上記熱交換素子(50)を通過した後、空気熱交換器(11)を通過する際に冷媒と熱交換し、排出空気(EA)として室外に排出される。   On the other hand, in the heat exchange element (50), the outdoor air (first air) (OA) having a high temperature and the indoor air (second air) (RA) having a low temperature exchange heat to thereby generate indoor air ( RA) is heated and outdoor air (OA) is cooled. The room air (RA), which is the second air, is heated by the heat exchange element (50) and then passes through the first adsorption heat exchanger (13), and the adsorbent of the first adsorption heat exchanger (13) is removed. After being regenerated, it is discharged outside as outdoor air (EA). In addition, after passing through the heat exchange element (50), the outdoor air (OA) exchanges heat with the refrigerant when passing through the air heat exchanger (11), and is discharged outside as outdoor air (EA). .

また、第２運転時、圧縮機(21)から吐出された冷媒は、第１空気熱交換器(11)と第２吸着熱交換器(14)とで凝縮した後、膨張弁(23)で膨張し、第１吸着熱交換器(13)と第２空気熱交換器(12)とで蒸発して圧縮機(21)に吸入される。   In the second operation, the refrigerant discharged from the compressor (21) is condensed by the first air heat exchanger (11) and the second adsorption heat exchanger (14), and then is expanded by the expansion valve (23). It expands, is evaporated by the first adsorption heat exchanger (13) and the second air heat exchanger (12), and is sucked into the compressor (21).

その際、第１吸着熱交換器(13)において室内の潜熱処理が行われ、第２空気熱交換器(12)において室内の顕熱処理が行われる。つまり、室内空気(RA)は、一部が第１吸着熱交換器(13)を通過する際に水分が吸着剤に吸着されることで減湿（潜熱処理）されて室内に戻り、他の一部が第２空気熱交換器(12)を通過する際に冷却（顕熱処理）されて室内に戻る。こうすることにより、室内の冷房と除湿を効率よく行うことができる。   At that time, an indoor latent heat treatment is performed in the first adsorption heat exchanger (13), and an indoor sensible heat treatment is performed in the second air heat exchanger (12). In other words, when a part of the room air (RA) passes through the first adsorption heat exchanger (13), the moisture is adsorbed by the adsorbent and dehumidified (latent heat treatment) to return to the room. When a part passes through the second air heat exchanger (12), it is cooled (sensible heat treatment) and returned to the room. By doing so, indoor cooling and dehumidification can be performed efficiently.

一方、上記熱交換素子(50)では、温度の高い室外空気（第１空気）(OA)と温度の低い室内空気（第２空気）(RA)とが熱交換をすることにより、室内空気(RA)が加熱され、室外空気(OA)が冷却される。第２空気である室内空気(RA)は、熱交換素子(50)で加熱された後に第２吸着熱交換器(14)を通過し、該第２吸着熱交換器(14)の吸着剤を再生してから排出空気(EA)として室外に排出される。また、室外空気(OA)は、上記熱交換素子(50)を通過した後、空気熱交換器(11)を通過する際に冷媒と熱交換し、排出空気(EA)として室外に排出される。   On the other hand, in the heat exchange element (50), the outdoor air (first air) (OA) having a high temperature and the indoor air (second air) (RA) having a low temperature exchange heat to thereby generate indoor air ( RA) is heated and outdoor air (OA) is cooled. The indoor air (RA), which is the second air, is heated by the heat exchange element (50) and then passes through the second adsorption heat exchanger (14), and the adsorbent of the second adsorption heat exchanger (14) is removed. After being regenerated, it is discharged outside as outdoor air (EA). In addition, after passing through the heat exchange element (50), the outdoor air (OA) exchanges heat with the refrigerant when passing through the air heat exchanger (11), and is discharged outside as outdoor air (EA). .

以上のようにして第１運転と第２運転とを交互に繰り返すことにより、室内の顕熱負荷を連続的に処理しながら、室内の潜熱負荷も連続的に処理することができる。このときも、第１運転と第２運転は、室内の潜熱負荷が大きくなるほど短い時間間隔で切り換えられる。これにより、室内の潜熱負荷が大きいときは切換頻度を多くすることで除湿量を多くして室内の快適性を高め、逆に室内の潜熱負荷が小さいときは切換頻度を少なくすることで除湿量を少なくして省エネ性を高められる。   By alternately repeating the first operation and the second operation as described above, the indoor latent heat load can be continuously processed while the indoor sensible heat load is continuously processed. Also at this time, the first operation and the second operation are switched at shorter time intervals as the latent heat load in the room increases. As a result, when the indoor latent heat load is large, the dehumidification amount is increased by increasing the dehumidifying amount by increasing the switching frequency, and conversely, when the indoor latent heat load is small, the dehumidifying amount is decreased by decreasing the switching frequency. Energy savings can be improved by reducing

（暖房加湿運転）
暖房加湿運転時、第１四路切換弁(25)は第２の状態に切り換わり、図４（Ａ）の第１運転と図４（Ｂ）の第２運転とを交互に行う。そして、第１運転時は第２四路切換弁(26)が第１の状態に切り換わり、第２運転時は第２四路切換弁(26)が第２の状態に切り換わる。また、第１運転時と第２運転時のいずれも、膨張弁(23)は所定開度に絞られる。 (Heating and humidifying operation)
During the heating / humidifying operation, the first four-way selector valve (25) switches to the second state, and the first operation in FIG. 4 (A) and the second operation in FIG. 4 (B) are performed alternately. The second four-way switching valve (26) is switched to the first state during the first operation, and the second four-way switching valve (26) is switched to the second state during the second operation. In both the first operation and the second operation, the expansion valve (23) is throttled to a predetermined opening.

この状態において、第１運転時、圧縮機(21)から吐出された冷媒は、第２空気熱交換器(12)と第２吸着熱交換器(14)とで凝縮した後、膨張弁(23)で膨張し、第１吸着熱交換器(13)と第１空気熱交換器(11)とで蒸発して圧縮機(21)に吸入される。   In this state, the refrigerant discharged from the compressor (21) during the first operation is condensed by the second air heat exchanger (12) and the second adsorption heat exchanger (14), and then the expansion valve (23 ), Evaporates in the first adsorption heat exchanger (13) and the first air heat exchanger (11), and is sucked into the compressor (21).

その際、第２吸着熱交換器(14)において室内の潜熱処理が行われ、第２空気熱交換器(12)において室内の顕熱処理が行われる。つまり、室内空気(RA)は、一部が第２吸着熱交換器(14)を通過する際に吸着剤を再生することで加湿（潜熱処理）されて室内に戻り、他の一部が第２空気熱交換器(12)を通過する際に加熱（顕熱処理）されて室内に戻る。こうすることにより、室内の暖房と加湿を効率よく行うことができる。   At that time, an indoor latent heat treatment is performed in the second adsorption heat exchanger (14), and an indoor sensible heat treatment is performed in the second air heat exchanger (12). That is, the room air (RA) is humidified (latent heat treatment) by regenerating the adsorbent when part of the room air passes through the second adsorption heat exchanger (14) and returns to the room, and the other part of the room air (RA). When passing through the two air heat exchanger (12), it is heated (sensible heat treatment) and returned to the room. By doing so, indoor heating and humidification can be performed efficiently.

一方、上記熱交換素子(50)では、温度の高い室内空気（第１空気）(RA)と温度の低い室外空気（第２空気）(OA)とが熱交換をすることにより、室内空気(RA)が冷却され、室外空気(OA)が加熱される。第１空気である室内空気(RA)は、熱交換素子(50)で冷却された後に第１吸着熱交換器(13)を通過し、該第１吸着熱交換器(13)の吸着剤に水分を与えてから排出空気(EA)として室外に排出される。また、室外空気(OA)は、上記熱交換素子(50)を通過した後、空気熱交換器(11)を通過する際に冷媒と熱交換し、排出空気(EA)として室外に排出される。   On the other hand, in the heat exchange element (50), the indoor air (first air) (RA) having a high temperature and the outdoor air (second air) (OA) having a low temperature exchange heat to thereby generate indoor air ( RA) is cooled and outdoor air (OA) is heated. The indoor air (RA), which is the first air, is cooled by the heat exchange element (50), passes through the first adsorption heat exchanger (13), and becomes the adsorbent of the first adsorption heat exchanger (13). After giving moisture, it is discharged out of the room as exhaust air (EA). In addition, after passing through the heat exchange element (50), the outdoor air (OA) exchanges heat with the refrigerant when passing through the air heat exchanger (11), and is discharged outside as outdoor air (EA). .

また、第２運転時、圧縮機(21)から吐出された冷媒は、第２空気熱交換器(12)と第１吸着熱交換器(13)とで凝縮した後、膨張弁(23)で膨張し、第２吸着熱交換器(14)と第１空気熱交換器(11)とで蒸発して圧縮機(21)に吸入される。   In the second operation, the refrigerant discharged from the compressor (21) is condensed by the second air heat exchanger (12) and the first adsorption heat exchanger (13), and then is expanded by the expansion valve (23). It expands, is evaporated by the second adsorption heat exchanger (14) and the first air heat exchanger (11), and is sucked into the compressor (21).

その際、第１吸着熱交換器(13)において室内の潜熱処理が行われ、第２空気熱交換器(12)において室内の顕熱処理が行われる。つまり、室内空気(RA)は、一部が第１吸着熱交換器(13)を通過する際に吸着剤を再生することで加湿（潜熱処理）されて室内に戻り、他の一部が第２空気熱交換器(12)を通過する際に加熱（顕熱処理）されて室内に戻る。こうすることにより、室内の暖房と加湿を効率よく行うことができる。   At that time, an indoor latent heat treatment is performed in the first adsorption heat exchanger (13), and an indoor sensible heat treatment is performed in the second air heat exchanger (12). That is, the room air (RA) is humidified (latent heat treatment) by regenerating the adsorbent when part of it passes through the first adsorption heat exchanger (13) and returns to the room, and the other part is first. When passing through the two air heat exchanger (12), it is heated (sensible heat treatment) and returned to the room. By doing so, indoor heating and humidification can be performed efficiently.

一方、上記熱交換素子(50)では、温度の高い室内空気（第１空気）(RA)と温度の低い室外空気（第２空気）(OA)とが熱交換をすることにより、室内空気(RA)が冷却され、室外空気(OA)が加熱される。第１空気である室内空気(RA)は、熱交換素子(50)で冷却された後に第２吸着熱交換器(14)を通過し、該第２吸着熱交換器(14)の吸着剤に水分を与えてから排出空気(EA)として室外に排出される。また、室外空気(OA)は、上記熱交換素子(50)を通過した後、空気熱交換器(11)を通過する際に冷媒と熱交換し、排出空気(EA)として室外に排出される。   On the other hand, in the heat exchange element (50), the indoor air (first air) (RA) having a high temperature and the outdoor air (second air) (OA) having a low temperature exchange heat to thereby generate indoor air ( RA) is cooled and outdoor air (OA) is heated. The indoor air (RA), which is the first air, is cooled by the heat exchange element (50), passes through the second adsorption heat exchanger (14), and becomes the adsorbent of the second adsorption heat exchanger (14). After giving moisture, it is discharged out of the room as exhaust air (EA). In addition, after passing through the heat exchange element (50), the outdoor air (OA) exchanges heat with the refrigerant when passing through the air heat exchanger (11), and is discharged outside as outdoor air (EA). .

以上のようにして第１運転と第２運転とを交互に繰り返すことにより、室内の顕熱負荷を連続的に処理しながら、室内の潜熱負荷も連続的に処理される。このときも、第１運転と第２運転は、室内の潜熱負荷に応じた時間間隔で切り換えられる。   By alternately repeating the first operation and the second operation as described above, the indoor latent heat load is continuously processed while the indoor sensible heat load is continuously processed. Also at this time, the first operation and the second operation are switched at time intervals corresponding to the indoor latent heat load.

−実施形態２の効果−
この実施形態２によれば、冷房除湿運転時には、再生用空気である第２空気（室内空気(RA)）を熱交換素子(50)で予め加熱するようにしているので、吸着剤を効率よく再生できる。したがって、放湿動作を吸湿動作に切り換えたときには吸着剤で水分を効率よく吸着できるので、除湿能力を高められる。また、暖房加湿運転時には、吸着用空気である第１空気（室内空気(RA)）を熱交換素子(50)で予め冷却するようにしているので、吸着剤で水分を効率よく吸着できる。したがって、吸湿動作を放湿動作に切り換えたときには吸着剤を効率よく再生できるので、加湿能力を高められる。 -Effect of Embodiment 2-
According to the second embodiment, during the cooling and dehumidifying operation, the second air that is regeneration air (room air (RA)) is preheated by the heat exchange element (50). Can play. Therefore, when the moisture releasing operation is switched to the moisture absorbing operation, moisture can be efficiently adsorbed by the adsorbent, so that the dehumidifying ability can be enhanced. Further, during the heating and humidifying operation, the first air (indoor air (RA)) as the adsorption air is cooled in advance by the heat exchange element (50), so that the moisture can be efficiently adsorbed by the adsorbent. Therefore, when the moisture absorbing operation is switched to the moisture releasing operation, the adsorbent can be efficiently regenerated, so that the humidifying ability can be enhanced.

また、室内の潜熱負荷が大きいときは第１運転と第２運転の切換頻度を多くし、逆に潜熱負荷が小さいときは第１運転と第２運転の切換頻度を少なくしているので、室内の快適性と省エネ性のバランスに優れた運転を行うことが可能となる。   Further, when the indoor latent heat load is large, the switching frequency between the first operation and the second operation is increased, and conversely, when the latent heat load is small, the switching frequency between the first operation and the second operation is decreased. Driving with a good balance between comfort and energy saving.

さらに、この空気調和装置(10)は、第１空気（室外空気）と第２空気（室内空気）とが熱交換を行う熱交換素子(50)を備えている。この熱交換素子(50)は、第１空気の流通通路と第２空気の流通通路とに跨って配置されるとともに回転可能な回転式の顕熱交換器により構成されている。   Further, the air conditioner (10) includes a heat exchange element (50) for exchanging heat between the first air (outdoor air) and the second air (indoor air).

−運転動作−
次に、この空気調和装置(10)の運転動作について説明する。 -Driving action-
Next, the operation of the air conditioner (10) will be described.

（冷房除湿運転）
冷房除湿運転時、第１四路切換弁(25)は第１の状態に切り換わり、図５（Ａ）の第１運転と図５（Ｂ）の第２運転とを交互に行う。そして、第１運転時は第２四路切換弁(26)が第１の状態に切り換わり、第２運転時は第２四路切換弁(26)が第２の状態に切り換わる。また、第１運転時と第２運転時のいずれも、第１膨張弁(31)及び第２膨張弁(32)は所定開度に絞られる。 (Cooling dehumidification operation)
During the cooling and dehumidifying operation, the first four-way switching valve (25) is switched to the first state, and the first operation in FIG. 5 (A) and the second operation in FIG. 5 (B) are alternately performed. The second four-way switching valve (26) is switched to the first state during the first operation, and the second four-way switching valve (26) is switched to the second state during the second operation. Further, in both the first operation and the second operation, the first expansion valve (31) and the second expansion valve (32) are throttled to a predetermined opening degree.

この状態において、第１運転時、圧縮機(21)から吐出された冷媒の一部は、第１空気熱交換器(11)で凝縮した後、第１膨張弁(31)で膨張し、第２空気熱交換器(12)で蒸発して圧縮機(21)に吸入される。また、圧縮機(21)から吐出された冷媒の残りは、第１吸着熱交換器(13)で凝縮した後、第２膨張弁(32)で膨張し、第２吸着熱交換器(14)で蒸発して圧縮機(21)に吸入される。   In this state, during the first operation, a part of the refrigerant discharged from the compressor (21) is condensed by the first air heat exchanger (11) and then expanded by the first expansion valve (31). It is evaporated by the two air heat exchanger (12) and sucked into the compressor (21). The remainder of the refrigerant discharged from the compressor (21) is condensed by the first adsorption heat exchanger (13), then expanded by the second expansion valve (32), and the second adsorption heat exchanger (14). And is sucked into the compressor (21).

その際、第２吸着熱交換器(14)において室内の潜熱処理が行われ、第２空気熱交換器(12)において室内の顕熱処理が行われる。つまり、室内空気(RA)は、一部が第２吸着熱交換器(14)を通過する際に水分が吸着剤に吸着されることで減湿（潜熱処理）されて室内に戻り、他の一部が第２空気熱交換器(12)を通過する際に冷却（顕熱処理）されて室内に戻る。こうすることにより、室内の冷房と除湿を効率よく行うことができる。   At that time, an indoor latent heat treatment is performed in the second adsorption heat exchanger (14), and an indoor sensible heat treatment is performed in the second air heat exchanger (12). In other words, when part of the room air (RA) passes through the second adsorption heat exchanger (14), the moisture is adsorbed by the adsorbent and dehumidified (latent heat treatment) to return to the room. When a part passes through the second air heat exchanger (12), it is cooled (sensible heat treatment) and returned to the room. By doing so, indoor cooling and dehumidification can be performed efficiently.

一方、上記熱交換素子(50)では、温度の高い室外空気（第１空気）(OA)と温度の低い室内空気（第２空気）(RA)とが熱交換をすることにより、室内空気(RA)が加熱され、室外空気(OA)が冷却される。第２空気である室内空気(RA)は、熱交換素子(50)で加熱された後に第１吸着熱交換器(13)を通過し、該第１吸着熱交換器(13)の吸着剤を再生してから排出空気(EA)として室外に排出される。また、室外空気(OA)は、上記熱交換素子(50)を通過した後、空気熱交換器(11)を通過する際に冷媒と熱交換し、排出空気(EA)として室外に排出される。   On the other hand, in the heat exchange element (50), the outdoor air (first air) (OA) having a high temperature and the indoor air (second air) (RA) having a low temperature exchange heat to thereby generate indoor air ( RA) is heated and outdoor air (OA) is cooled. The room air (RA), which is the second air, is heated by the heat exchange element (50) and then passes through the first adsorption heat exchanger (13), and the adsorbent of the first adsorption heat exchanger (13) is removed. After being regenerated, it is discharged outside as outdoor air (EA). In addition, after passing through the heat exchange element (50), the outdoor air (OA) exchanges heat with the refrigerant when passing through the air heat exchanger (11), and is discharged outside as outdoor air (EA). .

また、第２運転時、圧縮機(21)から吐出された冷媒の一部は、第１空気熱交換器(11)で凝縮した後、第１膨張弁(31)で膨張し、第２空気熱交換器(12)で蒸発して圧縮機(21)に吸入される。圧縮機(21)から吐出された冷媒の残りは、第２吸着熱交換器(14)で凝縮した後、第２膨張弁(32)で膨張し、第１吸着熱交換器(13)で蒸発して圧縮機(21)に吸入される。   Further, during the second operation, a part of the refrigerant discharged from the compressor (21) is condensed by the first air heat exchanger (11), then expanded by the first expansion valve (31), and the second air It evaporates in the heat exchanger (12) and is sucked into the compressor (21). The remaining refrigerant discharged from the compressor (21) is condensed by the second adsorption heat exchanger (14), then expanded by the second expansion valve (32), and evaporated by the first adsorption heat exchanger (13). Then, it is sucked into the compressor (21).

その際、第１吸着熱交換器(13)において室内の潜熱処理が行われ、第２空気熱交換器(12)において室内の顕熱処理が行われる。つまり、室内空気(RA)は、一部が第１吸着熱交換器(13)を通過する際に水分が吸着剤に吸着されることで減湿（潜熱処理）されて室内に戻り、他の一部が第２空気熱交換器(12)を通過する際に冷却（顕熱処理）されて室内に戻る。こうすることにより、室内の冷房と除湿を効率よく行うことができる。   At that time, an indoor latent heat treatment is performed in the first adsorption heat exchanger (13), and an indoor sensible heat treatment is performed in the second air heat exchanger (12). In other words, when a part of the room air (RA) passes through the first adsorption heat exchanger (13), the moisture is adsorbed by the adsorbent and dehumidified (latent heat treatment) to return to the room. When a part passes through the second air heat exchanger (12), it is cooled (sensible heat treatment) and returned to the room. By doing so, indoor cooling and dehumidification can be performed efficiently.

一方、上記熱交換素子(50)では、温度の高い室外空気（第１空気）(OA)と温度の低い室内空気（第２空気）(RA)とが熱交換をすることにより、室内空気(RA)が加熱され、室外空気(OA)が冷却される。第２空気である室内空気(RA)は、熱交換素子(50)で加熱された後に第２吸着熱交換器(14)を通過し、該第２吸着熱交換器(14)の吸着剤を再生してから排出空気(EA)として室外に排出される。また、室外空気(OA)は、上記熱交換素子(50)を通過した後、空気熱交換器(11)を通過する際に冷媒と熱交換し、排出空気(EA)として室外に排出される。   On the other hand, in the heat exchange element (50), the outdoor air (first air) (OA) having a high temperature and the indoor air (second air) (RA) having a low temperature exchange heat to thereby generate indoor air ( RA) is heated and outdoor air (OA) is cooled. The indoor air (RA), which is the second air, is heated by the heat exchange element (50) and then passes through the second adsorption heat exchanger (14), and the adsorbent of the second adsorption heat exchanger (14) is removed. After being regenerated, it is discharged outside as outdoor air (EA). In addition, after passing through the heat exchange element (50), the outdoor air (OA) exchanges heat with the refrigerant when passing through the air heat exchanger (11), and is discharged outside as outdoor air (EA). .

以上のようにして第１運転と第２運転とを交互に繰り返すことにより、室内の顕熱負荷を連続的に処理しながら、室内の潜熱負荷も連続的に処理される。このときも、第１運転と第２運転は、室内の潜熱負荷が大きくなるほど短い時間間隔で切り換えられる。これにより、室内の潜熱負荷が大きいときは切換頻度を多くすることで除湿量を多くして室内の快適性を高め、逆に室内の潜熱負荷が小さいときは切換頻度を少なくすることで除湿量を少なくして省エネ性を高められる。   By alternately repeating the first operation and the second operation as described above, the indoor latent heat load is continuously processed while the indoor sensible heat load is continuously processed. Also at this time, the first operation and the second operation are switched at shorter time intervals as the latent heat load in the room increases. As a result, when the indoor latent heat load is large, the dehumidification amount is increased by increasing the dehumidifying amount by increasing the switching frequency, and conversely, when the indoor latent heat load is small, the dehumidifying amount is decreased by decreasing the switching frequency. Energy savings can be improved by reducing

（暖房加湿運転）
暖房加湿運転時、第１四路切換弁(25)は第２の状態に切り換わり、図６（Ａ）の第１運転と図６（Ｂ）の第２運転とを交互に行う。そして、第１運転時は第２四路切換弁(26)が第１の状態に切り換わり、第２運転時は第２四路切換弁(26)が第２の状態に切り換わる。また、第１運転時と第２運転時のいずれも、膨張弁(23)は所定開度に絞られる。 (Heating and humidifying operation)
During the heating / humidifying operation, the first four-way selector valve (25) is switched to the second state, and the first operation in FIG. 6 (A) and the second operation in FIG. 6 (B) are alternately performed. The second four-way switching valve (26) is switched to the first state during the first operation, and the second four-way switching valve (26) is switched to the second state during the second operation. In both the first operation and the second operation, the expansion valve (23) is throttled to a predetermined opening.

この状態において、第１運転時、圧縮機(21)から吐出された冷媒の一部は、第２空気熱交換器(12)で凝縮した後、第１膨張弁(31)で膨張し、第１空気熱交換器(11)で蒸発して圧縮機(21)に吸入される。また、圧縮機(21)から吐出された冷媒の残りは、第２吸着熱交換器(14)で凝縮した後、第２膨張弁(32)で膨張し、第１吸着熱交換器(13)で蒸発して圧縮機(21)に戻る。   In this state, during the first operation, a part of the refrigerant discharged from the compressor (21) is condensed by the second air heat exchanger (12) and then expanded by the first expansion valve (31). 1 It evaporates in the air heat exchanger (11) and is sucked into the compressor (21). The remainder of the refrigerant discharged from the compressor (21) is condensed by the second adsorption heat exchanger (14), then expanded by the second expansion valve (32), and the first adsorption heat exchanger (13). To evaporate and return to the compressor (21).

その際、第２吸着熱交換器(14)において室内の潜熱処理が行われ、第２空気熱交換器(12)において室内の顕熱処理が行われる。つまり、室内空気(RA)は、一部が第２吸着熱交換器(14)を通過する際に吸着剤を再生することで加湿（潜熱処理）されて室内に戻り、他の一部が第２空気熱交換器(12)を通過する際に加熱（顕熱処理）されて室内に戻る。こうすることにより、室内の暖房と加湿を効率よく行うことができる。   At that time, an indoor latent heat treatment is performed in the second adsorption heat exchanger (14), and an indoor sensible heat treatment is performed in the second air heat exchanger (12). That is, the room air (RA) is humidified (latent heat treatment) by regenerating the adsorbent when part of the room air passes through the second adsorption heat exchanger (14) and returns to the room, and the other part of the room air (RA). When passing through the two air heat exchanger (12), it is heated (sensible heat treatment) and returned to the room. By doing so, indoor heating and humidification can be performed efficiently.

一方、上記熱交換素子(50)では、温度の高い室内空気（第１空気）(RA)と温度の低い室外空気（第２空気）(OA)とが熱交換をすることにより、室内空気(RA)が冷却され、室外空気(OA)が加熱される。第１空気である室内空気(RA)は、熱交換素子(50)で冷却された後に第１吸着熱交換器(13)を通過し、該第１吸着熱交換器(13)の吸着剤に水分を与えてから排出空気(EA)として室外に排出される。また、室外空気(OA)は、上記熱交換素子(50)を通過した後、空気熱交換器(11)を通過する際に冷媒と熱交換し、排出空気(EA)として室外に排出される。   On the other hand, in the heat exchange element (50), the indoor air (first air) (RA) having a high temperature and the outdoor air (second air) (OA) having a low temperature exchange heat to thereby generate indoor air ( RA) is cooled and outdoor air (OA) is heated. The indoor air (RA), which is the first air, is cooled by the heat exchange element (50), passes through the first adsorption heat exchanger (13), and becomes the adsorbent of the first adsorption heat exchanger (13). After giving moisture, it is discharged out of the room as exhaust air (EA). In addition, after passing through the heat exchange element (50), the outdoor air (OA) exchanges heat with the refrigerant when passing through the air heat exchanger (11), and is discharged outside as outdoor air (EA). .

また、第２運転時、圧縮機(21)から吐出された冷媒の一部は、第２空気熱交換器(12)で凝縮した後、第１膨張弁(31)で膨張し、第１空気熱交換器(11)で蒸発して圧縮機(21)に吸入される。圧縮機(21)から吐出された冷媒の残りは、第１吸着熱交換器(13)で凝縮した後、第２膨張弁(32)で膨張し、第２吸着熱交換器(14)で蒸発して圧縮機(21)に戻る。   Further, during the second operation, a part of the refrigerant discharged from the compressor (21) is condensed by the second air heat exchanger (12), then expanded by the first expansion valve (31), and the first air It evaporates in the heat exchanger (11) and is sucked into the compressor (21). The remaining refrigerant discharged from the compressor (21) is condensed by the first adsorption heat exchanger (13), then expanded by the second expansion valve (32), and evaporated by the second adsorption heat exchanger (14). And return to the compressor (21).

その際、第１吸着熱交換器(13)において室内の潜熱処理が行われ、第２空気熱交換器(12)において室内の顕熱処理が行われる。つまり、室内空気(RA)は、一部が第１吸着熱交換器(13)を通過する際に吸着剤を再生することで加湿（潜熱処理）されて室内に戻り、他の一部が第２空気熱交換器(12)を通過する際に加熱（顕熱処理）されて室内に戻る。こうすることにより、室内の暖房と加湿を効率よく行うことができる。   At that time, an indoor latent heat treatment is performed in the first adsorption heat exchanger (13), and an indoor sensible heat treatment is performed in the second air heat exchanger (12). That is, the room air (RA) is humidified (latent heat treatment) by regenerating the adsorbent when part of it passes through the first adsorption heat exchanger (13) and returns to the room, and the other part is first. When passing through the two air heat exchanger (12), it is heated (sensible heat treatment) and returned to the room. By doing so, indoor heating and humidification can be performed efficiently.

一方、上記熱交換素子(50)では、温度の高い室内空気（第１空気）(RA)と温度の低い室外空気（第２空気）(OA)とが熱交換をすることにより、室内空気(RA)が冷却され、室外空気(OA)が加熱される。第１空気である室内空気(RA)は、熱交換素子(50)で冷却された後に第２吸着熱交換器(14)を通過し、該第２吸着熱交換器(14)の吸着剤に水分を与えてから排出空気(EA)として室外に排出される。また、室外空気(OA)は、上記熱交換素子(50)を通過した後、空気熱交換器(11)を通過する際に冷媒と熱交換し、排出空気(EA)として室外に排出される。   On the other hand, in the heat exchange element (50), the indoor air (first air) (RA) having a high temperature and the outdoor air (second air) (OA) having a low temperature exchange heat to thereby generate indoor air ( RA) is cooled and outdoor air (OA) is heated. The indoor air (RA), which is the first air, is cooled by the heat exchange element (50), passes through the second adsorption heat exchanger (14), and becomes the adsorbent of the second adsorption heat exchanger (14). After giving moisture, it is discharged out of the room as exhaust air (EA). In addition, after passing through the heat exchange element (50), the outdoor air (OA) exchanges heat with the refrigerant when passing through the air heat exchanger (11), and is discharged outside as outdoor air (EA). .

以上のようにして第１運転と第２運転とを交互に繰り返すことにより、室内の顕熱負荷を連続的に処理しながら、室内の潜熱負荷も連続的に処理される。このときも、第１運転と第２運転は、室内の潜熱負荷に応じた時間間隔で切り換えられる。   By alternately repeating the first operation and the second operation as described above, the indoor latent heat load is continuously processed while the indoor sensible heat load is continuously processed. Also at this time, the first operation and the second operation are switched at time intervals corresponding to the indoor latent heat load.

−実施形態３の効果−
この実施形態３においても、冷房除湿運転時には、再生用空気である第２空気（室内空気(RA)）を熱交換素子(50)で予め加熱するようにしているので、吸着剤を効率よく再生できる。したがって、放湿動作を吸湿動作に切り換えたときには吸着剤で水分を効率よく吸着できるので、除湿能力を高められる。また、暖房加湿運転時には、吸着用空気である第１空気（室内空気(RA)）を熱交換素子(50)で予め冷却するようにしているので、吸着剤で水分を効率よく吸着できる。したがって、吸湿動作を放湿動作に切り換えたときには吸着剤を効率よく再生できるので、加湿能力を高められる。 -Effect of Embodiment 3-
Also in the third embodiment, during the cooling and dehumidifying operation, the second air (room air (RA)) that is the regeneration air is preheated by the heat exchange element (50), so that the adsorbent is efficiently regenerated. it can. Therefore, when the moisture releasing operation is switched to the moisture absorbing operation, moisture can be efficiently adsorbed by the adsorbent, so that the dehumidifying ability can be enhanced. Further, during the heating and humidifying operation, the first air (indoor air (RA)) that is the adsorption air is cooled in advance by the heat exchange element (50), so that the moisture can be efficiently adsorbed by the adsorbent. Therefore, when the moisture absorbing operation is switched to the moisture releasing operation, the adsorbent can be efficiently regenerated, so that the humidifying ability can be enhanced.

また、室内の潜熱負荷が大きいときは第１運転と第２運転の切換頻度を多くし、逆に潜熱負荷が小さいときは第１運転と第２運転の切換頻度を少なくしているので、室内の快適性と省エネ性のバランスに優れた運転を行うことが可能となる。   Further, when the indoor latent heat load is large, the switching frequency between the first operation and the second operation is increased, and conversely, when the latent heat load is small, the switching frequency between the first operation and the second operation is decreased. Driving with a good balance between comfort and energy saving.

《発明の実施形態４》
実施形態４に係る空気調和装置(10)は、図７及び図８に示すように、実施形態３と冷媒回路の構成は同じである。このため、具体的な構成について、説明は省略する。 << Embodiment 4 of the Invention >>
As shown in FIGS. 7 and 8, the air conditioner (10) according to the fourth embodiment has the same configuration of the refrigerant circuit as that of the third embodiment. For this reason, description about a specific structure is abbreviate | omitted.

実施形態３と実施形態４で異なる点は、実施形態３の装置を室内への給気量よりも室外への排気量が多い排気扇タイプに構成しているのに対して、実施形態４の装置を室内への給気量と室外への排気量がバランスする換気扇タイプに構成している点である。   The difference between the third embodiment and the fourth embodiment is that the apparatus of the third embodiment is configured as an exhaust fan type in which the amount of exhaust to the outside is larger than the amount of air supplied to the room, whereas the device of the fourth embodiment is different. The point is that the apparatus is configured as a ventilation fan type in which the amount of air supplied to the room and the amount of exhaust to the outside are balanced.

また、この実施形態において、冷房運転時と暖房運転時のいずれも、熱交換素子(50)を通過する第１空気は吸着熱交換器(13,14) を通過する前の吸着用空気であり、熱交換素子(50)を通過する第２空気は吸着熱交換器(13,14) を通過する前の再生用空気である。そして、熱交換素子(50)において第１空気と第２空気が熱交換し、第１空気が冷却されて第２空気が加熱される。冷房運転時は第１空気が室外空気(OA)、第２空気が室内空気(RA)となり、暖房運転時は第１空気が室内空気(RA)、第２空気が室外空気(OA)となる。   In this embodiment, the first air passing through the heat exchange element (50) is the air for adsorption before passing through the adsorption heat exchanger (13, 14) in both the cooling operation and the heating operation. The second air passing through the heat exchange element (50) is the regenerating air before passing through the adsorption heat exchanger (13, 14). Then, in the heat exchange element (50), the first air and the second air exchange heat, the first air is cooled, and the second air is heated. During cooling operation, the first air is outdoor air (OA) and the second air is indoor air (RA). During heating operation, the first air is indoor air (RA) and the second air is outdoor air (OA). .

次に、この空気調和装置(10)の具体的な装置構成を図９及び図１０を参照して説明する。図９は、この空気調和装置(10)の設置状態と運転時の空気の流れを示す概念図であり、図１０は、（Ａ）図が平面構造図、（Ｂ）図が左側面構造図、（Ｃ）図が右側面構造図である。この空気調和装置(10)は、２つの空気熱交換器(11,12) と２つの吸着熱交換器(13,14) を１つのケーシング(150) 内に収納し、一体型にして天井裏に設置したものである。なお、図７及び図８の回路構成図と図９の設置図とには、熱交換素子(50)として回転式の顕熱交換器を示しているが、図１０の装置構成図では、熱交換素子(50)としてを第１空気と第２空気が交差して流れる顕熱交換器（いわゆる直交流式の顕熱交換器）を図示している。このように、熱交換素子(50)には回転式や直交流式のどちらを採用してもよい。   Next, a specific device configuration of the air conditioner (10) will be described with reference to FIGS. FIG. 9 is a conceptual diagram showing the installation state of the air conditioner (10) and the air flow during operation.

例えば、上記各実施形態では、空気熱交換器(11,12) 及び吸着熱交換器(13,14) を１枚または２枚用いた構成としているが、空気熱交換器(11,12) または吸着熱交換器(13,14) を３枚以上用いる構成にしてもよい。つまり、本発明は、少なくとも１つの熱交換器を、表面に吸着剤を担持した吸着熱交換器により構成した空気調和装置(10)において、第１空気と第２空気とが熱交換する熱交換素子(50)を用いたものであれば、熱交換器の枚数は適宜変更してもよい。   For example, in each of the above embodiments, one or two air heat exchangers (11, 12) and adsorption heat exchangers (13, 14) are used, but the air heat exchanger (11, 12) or A configuration in which three or more adsorption heat exchangers (13, 14) are used may be used. In other words, the present invention provides heat exchange in which heat is exchanged between the first air and the second air in an air conditioner (10) in which at least one heat exchanger is configured by an adsorption heat exchanger having an adsorbent supported on the surface. As long as the element (50) is used, the number of heat exchangers may be changed as appropriate.

また、上記熱交換素子(50)は、上記各実施形態で説明したような顕熱交換器に限らず、全熱交換器としてもよい。全熱交換器は、第１空気と第２空気の顕熱交換だけでなく、潜熱交換を行うことができる熱交換器である。このため、第１空気の湿度が第２空気の湿度より高い場合、全熱交換器によって第１空気の水分が第２空気へ奪われる。したがって、この第１空気を除湿時に室内へ給気する場合、この空気調和装置(10)の除湿能力を高めることができる。また、第１空気の湿度が第２空気の湿度より高い場合、全熱交換器によって第１空気の水分が第２空気へ付与される。したがって、この第２空気を加湿時に室内へ給気する場合、この空気調和装置(10)の加湿能力を高めることができる。   Further, the heat exchange element (50) is not limited to the sensible heat exchanger as described in the above embodiments, but may be a total heat exchanger. The total heat exchanger is a heat exchanger capable of performing latent heat exchange as well as sensible heat exchange between the first air and the second air. For this reason, when the humidity of 1st air is higher than the humidity of 2nd air, the water | moisture content of 1st air is taken to 2nd air by a total heat exchanger. Therefore, when the first air is supplied into the room at the time of dehumidification, the dehumidifying ability of the air conditioner (10) can be enhanced. Moreover, when the humidity of 1st air is higher than the humidity of 2nd air, the water | moisture content of 1st air is provided to 2nd air with a total heat exchanger. Therefore, when this 2nd air is supplied indoors at the time of humidification, the humidification capability of this air conditioning apparatus (10) can be improved.

また、実施形態１〜４の冷媒回路(20)を用いた構成において、冷媒回路(20)の具体的な構成や、空気調和装置(10)の具体的な装置構成（セパレート型にする場合の室外ユニット(110) 及び室内ユニット(120) の構成や、一体型にする場合のケーシング(150) の構成）などは、適宜変更してもよい。   In the configuration using the refrigerant circuit (20) of the first to fourth embodiments, the specific configuration of the refrigerant circuit (20) and the specific device configuration of the air conditioner (10) (separate type) The configurations of the outdoor unit (110) and the indoor unit (120), the configuration of the casing (150) in the case of being integrated, and the like may be appropriately changed.

さらに、冷温水回路(40)を用いた実施形態５において、潜熱処理を優先することを想定して、温水側、冷水側ともに、上流側に吸着熱交換器(13,14) を配置し、下流側に空気熱交換器(11,12) を配置するようにしているが、顕熱処理を優先することを想定して、上流側に空気熱交換器(11,12) を配置し、下流側に吸着熱交換器(13,14) を配置してもよい。   Furthermore, in Embodiment 5 using the cold / hot water circuit (40), assuming that priority is given to the latent heat treatment, an adsorption heat exchanger (13, 14) is arranged on the upstream side of both the hot water side and the cold water side, Although the air heat exchanger (11, 12) is arranged on the downstream side, assuming that priority is given to sensible heat treatment, the air heat exchanger (11, 12) is arranged on the upstream side, An adsorption heat exchanger (13, 14) may be arranged on the front.

また、上記実施形態１〜３は室内から室外に排出される空気の量が室内に供給される空気の量よりも多くなる排気扇タイプの空気調和装置(10)に本発明を適用した例、実施形態４〜６は室外に排出される空気の量と室内に供給される空気の量がバランスする換気扇タイプに適用した例であるが、本発明は、室外に排出される空気の量よりも室内に供給される空気の量が多くなる給気扇タイプに適用することも可能である。   In addition, the first to third embodiments are examples in which the present invention is applied to an exhaust fan type air conditioner (10) in which the amount of air discharged from the room to the outside is larger than the amount of air supplied to the room, Although Embodiment 4-6 is an example applied to the ventilation fan type which balances the quantity of the air discharged | emitted outdoor, and the quantity of the air supplied indoors, this invention is more than the quantity of the air discharged | emitted outdoor. It is also possible to apply to an air supply fan type in which the amount of air supplied into the room is increased.

以上説明したように、本発明は、室内の潜熱負荷と顕熱負荷を別々に処理する空気調和装置について有用である。   As described above, the present invention is useful for an air conditioner that separately processes an indoor latent heat load and a sensible heat load.
