Abstract

<P>PROBLEM TO BE SOLVED: To improve usability by suppressing generation of drain water, in an air conditioner performing a refrigerating cycle by heat exchange between a refrigerant and air. <P>SOLUTION: In a casing of the air conditioner, a refrigerant circuit (30) and a rotational rotor (40) carrying an absorbent are stored, and a first passage (21) and a second passage (22) are demarcated and formed. First air flowing on the first passage (21) is humidified by the rotational rotor (40) after heated by a first heat exchanger (32). The heated and humidified first air is blown out in a direction so as to become more distant from a person in a room. Meanwhile, second air flowing on the second passage (22) is cooled by a second heat exchanger (34) after dehumidified by the rotational rotor (40). The dehumidified and cooled second air is locally supplied to a region in the vicinity of the person in the room. Refrigerant evaporation temperature in the refrigerant circuit (30) is set higher than dew-point temperature of the second air passing through the second heat exchanger (34). In the second heat exchanger (34) serving as an evaporator, no drain water is generated. <P>COPYRIGHT: (C)2005,JPO&NCIPI

Description

本発明は、冷媒を空気と熱交換させて冷凍サイクルを行う空気調和装置に関する。   The present invention relates to an air conditioner that performs a refrigeration cycle by exchanging heat between a refrigerant and air.

従来より、特許文献１に開示されているように、冷媒回路を流れる冷媒を空気と熱交換させて冷凍サイクルを行う空気調和装置が知られている。この空気調和装置では、圧縮機及び室外熱交換器を備える室外ユニットと、室内熱交換器を備える室内ユニットとが接続されて冷媒回路が構成されている。   BACKGROUND ART Conventionally, as disclosed in Patent Document 1, an air conditioner that performs a refrigeration cycle by exchanging heat between refrigerant flowing in a refrigerant circuit and air is known. In this air conditioner, an outdoor unit including a compressor and an outdoor heat exchanger and an indoor unit including an indoor heat exchanger are connected to form a refrigerant circuit.

例えば、冷房動作時において、上記空気調和装置の室外熱交換器では、室外ファンの駆動により取り入れられた室外空気と冷媒回路の冷媒との間で熱交換が行われ、冷媒が凝縮する。凝縮した冷媒は、室外ユニットから室内ユニットへと流れ、室内熱交換器で室内ファンの駆動により取り入れられた室内空気と熱交換して蒸発する。   For example, during the cooling operation, in the outdoor heat exchanger of the air conditioner, heat is exchanged between the outdoor air taken in by driving the outdoor fan and the refrigerant in the refrigerant circuit, and the refrigerant is condensed. The condensed refrigerant flows from the outdoor unit to the indoor unit, and evaporates by exchanging heat with the indoor air taken in by driving the indoor fan in the indoor heat exchanger.

ここで、一般的な空気調和装置では、冷房動作において、冷凍サイクル中の冷媒蒸発温度が室内空気の露点温度よりも低くなるように設定されている。室内空気の冷却だけでなく、除湿も行う必要があるからである。このため、室内熱交換器では、室内空気中の水分が凝縮してドレン水が発生する。上記室内熱交換器において発生したドレン水は、この室内熱交換器に付設のドレンパンに貯留される。ドレンパンに貯留されたドレン水は、ある程度の水位に達したところでドレンポンプにより汲み出され、ドレンホースなどを通じて排出される。
特開２００２−１７４４５０号公報 Here, in a general air conditioner, in the cooling operation, the refrigerant evaporation temperature in the refrigeration cycle is set to be lower than the dew point temperature of the room air. This is because it is necessary to not only cool the indoor air but also dehumidify it. For this reason, in the indoor heat exchanger, moisture in the indoor air is condensed to generate drain water. The drain water generated in the indoor heat exchanger is stored in a drain pan attached to the indoor heat exchanger. The drain water stored in the drain pan is pumped out by a drain pump when it reaches a certain level, and is discharged through a drain hose or the like.
JP 2002-174450 A

上述のように、上記空気調和装置では、室内熱交換器において、冷媒回路を流れる冷媒と室内空気との熱交換により室内空気が露点温度に達してドレン水が発生する。このため、空気調和装置では、発生するドレン水を処理する必要が生じ、ドレン水を処理するための構造が求められる。   As described above, in the air conditioner, in the indoor heat exchanger, the indoor air reaches the dew point temperature due to heat exchange between the refrigerant flowing through the refrigerant circuit and the indoor air, and drain water is generated. For this reason, in the air conditioner, it is necessary to treat the generated drain water, and a structure for treating the drain water is required.

具体的には、ドレンパンに溜まったドレン水を汲み上げて排出するためのドレンポンプやドレンホースを設ける必要が生じる。そして、空気調和装置を据え付ける際には、ドレンホースを室外まで敷設する等の作業が必要となり、空気調和装置の据え付け作業が煩雑化したりその設置箇所が制約される等、空気調和装置の使い勝手が悪いという問題があった。   Specifically, it is necessary to provide a drain pump or a drain hose for pumping and discharging drain water accumulated in the drain pan. When installing the air conditioner, work such as laying a drain hose outside the room is necessary. There was a problem of being bad.

At the same time as the second heat exchanger (34) serves as an evaporator to cool and dehumidify the second air, and the second heat exchanger (34) serves as a condenser for the first air.

上記第１の発明では、第１空気の流れ方向における吸着素子（40）の上流側に第１熱交換器（32）が設けられ、第２空気の流れ方向における吸着素子（40）の下流側に第２熱交換器（34）が設けられる。また、吸着素子（40）は、吸着剤を有している。 -Action-
In the said 1st invention, the 1st heat exchanger (32) is provided in the upstream of the adsorption | suction element (40) in the flow direction of 1st air, and the downstream of the adsorption | suction element (40) in the flow direction of 2nd air Is provided with a second heat exchanger (34). Further, the adsorption element (40) has an adsorbent.

冷凍サイクル中に凝縮器となる第１熱交換器（32）では、第１空気と冷媒との間で熱交換が行われ、第１空気が加熱される。加熱された第１空気は、吸着素子（40）へ送られる。吸着素子（40）では、第１空気との接触によって、吸着素子（40）の吸着剤から水分が脱離する。この脱離した水分は、第１空気に付与され、第１空気が加湿される。   In the 1st heat exchanger (32) used as a condenser during a refrigerating cycle, heat exchange is performed between the 1st air and a refrigerant, and the 1st air is heated. The heated first air is sent to the adsorption element (40). In the adsorption element (40), moisture is desorbed from the adsorbent of the adsorption element (40) by contact with the first air. The desorbed moisture is given to the first air, and the first air is humidified.

一方、吸着素子（40）へ送られた第２空気は、それに含まれる水分が吸着剤に吸着される。除湿された第２空気は、第２熱交換器（34）へ送られる。冷凍サイクル中に蒸発器となる第２熱交換器（34）では、第２空気と冷媒との間で熱交換が行われ、第２空気が冷却される。このように、第２空気中の水分が吸着素子（40）の吸着剤に吸着されて第２空気が除湿される一方、この水分が第１空気に付与されて第１空気が加湿される。   On the other hand, the moisture contained in the second air sent to the adsorption element (40) is adsorbed by the adsorbent. The dehumidified second air is sent to the second heat exchanger (34). In the second heat exchanger (34) serving as an evaporator during the refrigeration cycle, heat exchange is performed between the second air and the refrigerant, and the second air is cooled. As described above, the moisture in the second air is adsorbed by the adsorbent of the adsorption element (40) to dehumidify the second air, while the moisture is given to the first air and the first air is humidified.

また、この発明では、冷凍サイクルにおける冷媒蒸発温度が、第２熱交換器（34）を通過する第２空気の露点温度よりも高く設定されている。このため、第２熱交換器（34）を通過中の第２空気は、常にその露点温度よりも高い温度に保たれる。つまり、空気調和装置の運転中において、蒸発器となる第２熱交換器（34）ではドレン水が発生しない。   In the present invention, the refrigerant evaporation temperature in the refrigeration cycle is set higher than the dew point temperature of the second air passing through the second heat exchanger (34). For this reason, the second air passing through the second heat exchanger (34) is always kept at a temperature higher than its dew point temperature. That is, during operation of the air conditioner, drain water is not generated in the second heat exchanger (34) serving as an evaporator.

上記第２の発明では、冷凍サイクル中に第１熱交換器（32）が凝縮器となり第２熱交換器（34）が蒸発器となる動作と、冷凍サイクル中に第２熱交換器（34）が凝縮器となり第１熱交換器（32）が蒸発器となる動作とが交互に繰り返し行われる。   In the second aspect of the invention, the operation in which the first heat exchanger (32) serves as a condenser during the refrigeration cycle and the second heat exchanger (34) serves as an evaporator, and the second heat exchanger (34 during the refrigeration cycle). ) Becomes a condenser, and the operation in which the first heat exchanger (32) becomes an evaporator is alternately repeated.

具体的に、第１熱交換器（32）が凝縮器となり第２熱交換器（34）が蒸発器となる動作において、第１熱交換器（32）の吸着剤と第１熱交換器（32）を通過する第１空気とが冷媒により加熱される。その際、第１空気には、吸着剤から脱離した水分が付与される。つまり、第１熱交換器（32）では、第１空気の加熱と加湿とが行われる。第２熱交換器（34）では、第２空気中の水分が吸着剤に吸着され、その際に生じる吸着熱が冷媒に吸熱される。また、第２熱交換器（34）を通過する第２空気から冷媒が吸熱する。つまり、第２熱交換器（34）では、第２空気の除湿と冷却とが行われる。   Specifically, in the operation in which the first heat exchanger (32) serves as a condenser and the second heat exchanger (34) serves as an evaporator, the adsorbent of the first heat exchanger (32) and the first heat exchanger ( The first air passing through 32) is heated by the refrigerant. At that time, moisture desorbed from the adsorbent is given to the first air. That is, in the first heat exchanger (32), the first air is heated and humidified. In the second heat exchanger (34), moisture in the second air is adsorbed by the adsorbent, and the heat of adsorption generated at that time is absorbed by the refrigerant. Further, the refrigerant absorbs heat from the second air passing through the second heat exchanger (34). That is, the second heat exchanger (34) performs dehumidification and cooling of the second air.

一方、第２熱交換器（34）が凝縮器となり第１熱交換器（32）が蒸発器となる動作において、第２熱交換器（34）の吸着剤と第２熱交換器（34）を通過する第１空気とが冷媒により加熱される。その際、第１空気には、吸着剤から脱離した水分が付与される。つまり、第２熱交換器（34）では、第１空気の加熱と加湿とが行われる。第１熱交換器（32）では、第２空気中の水分が吸着剤に吸着され、その際に生じる吸着熱が冷媒に吸熱される。また、第１熱交換器（32）を通過する第２空気から冷媒が吸熱する。つまり、第１熱交換器（32）では、第２空気の除湿と冷却とが行われる。   On the other hand, in the operation in which the second heat exchanger (34) serves as a condenser and the first heat exchanger (32) serves as an evaporator, the adsorbent of the second heat exchanger (34) and the second heat exchanger (34). The first air passing through is heated by the refrigerant. At that time, moisture desorbed from the adsorbent is given to the first air. That is, in the second heat exchanger (34), the first air is heated and humidified. In the first heat exchanger (32), moisture in the second air is adsorbed by the adsorbent, and the heat of adsorption generated at that time is absorbed by the refrigerant. Further, the refrigerant absorbs heat from the second air passing through the first heat exchanger (32). That is, in the first heat exchanger (32), the second air is dehumidified and cooled.

また、この発明では、冷凍サイクルにおける冷媒の蒸発温度が蒸発器となる第１，第２熱交換器（32,34）を通過する第２空気の露点温度よりも高く設定されている。このため、第１，第２熱交換器（32,34）を通過中の第２空気は、常にその露点温度よりも高い温度に保たれる。つまり、空気調和装置の運転中において、蒸発器となる第１，第２熱交換器（32,34）ではドレン水が発生しない。   Moreover, in this invention, the evaporation temperature of the refrigerant | coolant in a refrigerating cycle is set higher than the dew point temperature of the 2nd air which passes the 1st, 2nd heat exchanger (32, 34) used as an evaporator. For this reason, the second air passing through the first and second heat exchangers (32, 34) is always kept at a temperature higher than its dew point temperature. That is, during operation of the air conditioner, drain water is not generated in the first and second heat exchangers (32, 34) serving as evaporators.

上記第３の発明では、空気調和装置が室内に設置される。空気調和装置は、加湿され加熱された第１空気及び除湿され冷却された第２空気の一方を在室者の近傍へ局所的に供給して他方を在室者の存在しない方向に吹き出す。或いは、空気調和装置は、加湿され加熱された第１空気を在室者の近傍へ局所的に供給して除湿され冷却された第２空気を在室者の存在しない方向に吹き出す動作と、加湿され加熱された第１空気を在室者の存在しない方向に吹き出して除湿され冷却された第２空気を在室者の近傍へ局所的に供給する動作とを切り換えて行う。   In the third aspect, the air conditioner is installed indoors. The air conditioner locally supplies one of the humidified and heated first air and the dehumidified and cooled second air to the vicinity of the occupant and blows out the other in the direction in which the occupant does not exist. Alternatively, the air conditioner locally supplies the humidified and heated first air to the vicinity of the occupant and blows out the dehumidified and cooled second air in a direction in which the occupant does not exist, and the humidification Then, the heated first air is blown out in a direction in which no occupant is present, and the operation of locally supplying the dehumidified and cooled second air to the vicinity of the occupant is performed.

上記第４の発明では、第１空気の流れ方向における吸着素子（40）の下流側に第３熱交換器（35）が設けられる。冷凍サイクル中に蒸発器となる第３熱交換器（35）では、吸着素子（40）を通過後の第１空気と冷媒との間で熱交換が行われ、第１空気が冷却される。   In the fourth aspect of the invention, the third heat exchanger (35) is provided downstream of the adsorption element (40) in the flow direction of the first air. In the 3rd heat exchanger (35) used as an evaporator during a refrigerating cycle, heat exchange is performed between the 1st air after passing through an adsorption element (40), and a refrigerant, and the 1st air is cooled.

上記第５の発明では、吸着素子（40）に調湿側通路（85）と冷却側通路（86）とが交互に積層するように設けられる。吸着素子（40）の調湿側通路（85）へ第２空気を導入すると、第２空気中の水分が吸着剤に吸着される。その際に生じた吸着熱は、冷却側通路（86）を流れる空気によって奪われる。一方、吸着素子（40）の調湿側通路（85）へ加熱された第１空気を導入すると、第１空気によって加熱された吸着剤から水分が脱離する。つまり、吸着素子（40）が再生される。   In the fifth aspect of the invention, the humidity control side passage (85) and the cooling side passage (86) are provided alternately on the adsorption element (40). When the second air is introduced into the humidity control side passageway (85) of the adsorption element (40), the moisture in the second air is adsorbed by the adsorbent. The adsorption heat generated at that time is taken away by the air flowing through the cooling side passageway (86). On the other hand, when the heated first air is introduced into the humidity control side passageway (85) of the adsorption element (40), moisture is desorbed from the adsorbent heated by the first air. That is, the adsorption element (40) is regenerated.

上記第１及び第２の発明では、吸着剤に第２空気中の水分を吸着させることで第２空気を除湿し、その上で冷媒蒸発温度を蒸発器となる第１，第２熱交換器（32,34）を通過中の第２空気の露点温度よりも高く設定している。このため、空気調和装置では、第２空気の除湿が可能で、しかも蒸発器となる第１，第２熱交換器（32,34）でのドレン水の発生を抑止することができる。従って、本発明によれば、空気調和装置の使い勝手を向上させることができる。   In the first and second inventions described above, the first air and the second heat exchanger that dehumidify the second air by adsorbing the moisture in the second air to the adsorbent and then use the refrigerant evaporation temperature as an evaporator. It is set higher than the dew point temperature of the second air passing through (32, 34). For this reason, in the air conditioner, it is possible to dehumidify the second air and to suppress the generation of drain water in the first and second heat exchangers (32, 34) serving as an evaporator. Therefore, according to the present invention, usability of the air conditioner can be improved.

ここで、従来よりスポットクーラ等の室内に設置されて局所的な空調を行う空気調和装置が知られている。この種の空気調和装置には、蒸発器で発生するドレン水を処理するためのタンクが設けられていた。そして、このタンクがドレン水で一杯になると、ユーザーがタンクを取り外してドレン水を排出しなければならず、この点でも使い勝手が悪かった。   Here, conventionally, an air conditioner that is installed in a room such as a spot cooler and performs local air conditioning is known. This type of air conditioner is provided with a tank for treating drain water generated in the evaporator. When this tank was filled with drain water, the user had to remove the tank and drain the drain water, which was also unusable.

これに対し、上記第３の発明では、蒸発器となる第１，第２熱交換器（32,34）でドレン水が発生しないため、ドレン水を処理するためのタンクを設ける必要がなくなる。従って、室内に設置されて局所的な空調を行う空気調和装置に本発明を適用することで、この種の空気調和装置の使い勝手を向上させることができる。   On the other hand, in the third invention, since drain water is not generated in the first and second heat exchangers (32, 34) serving as an evaporator, there is no need to provide a tank for treating the drain water. Therefore, the usability of this type of air conditioner can be improved by applying the present invention to an air conditioner that is installed indoors and performs local air conditioning.

上記第４の発明では、冷媒回路（30）に蒸発器となる第２熱交換器（34）に加えて蒸発器となる第３熱交換器（35）が設けられている。このため、第２熱交換器（34）における第２空気からの熱回収量と第３熱交換器（35）における第１空気からの熱回収量の割合を自由に調整することができる。従って、本発明によれば、空気調和装置の運転能力の調整を容易に行うことができる。   In the fourth aspect of the invention, the refrigerant circuit (30) is provided with the third heat exchanger (35) serving as an evaporator in addition to the second heat exchanger (34) serving as an evaporator. For this reason, the ratio of the heat recovery amount from the second air in the second heat exchanger (34) and the heat recovery amount from the first air in the third heat exchanger (35) can be freely adjusted. Therefore, according to the present invention, it is possible to easily adjust the operating capacity of the air conditioner.

上記第５の発明によれば、吸着素子（40）において調湿側通路（85）を流れる空気が減湿される一方、吸着時に生じる吸着熱を冷却側通路（86）を流れる空気によって吸熱することができる。従って、本発明によれば、吸着時における吸着素子（40）の温度上昇を抑制することができ、吸着素子（40）の吸着能力を向上させることができる。   According to the fifth aspect of the present invention, the air flowing through the humidity adjusting side passageway (85) is dehumidified in the adsorption element (40), while the adsorption heat generated during adsorption is absorbed by the air flowing through the cooling side passageway (86). be able to. Therefore, according to this invention, the temperature rise of the adsorption | suction element (40) at the time of adsorption | suction can be suppressed, and the adsorption | suction capability of an adsorption | suction element (40) can be improved.

−運転動作−
上記空気調和装置の運転動作について説明する。 -Driving action-
The operation of the air conditioner will be described.

図２に示すように、ケーシング（1）内の第１通路（21）へは、室内空気が第１空気として取り込まれる。第１通路（21）へ取り込まれた第１空気は、第１熱交換器（32）へ送られる。一方、圧縮機（31）の運転中は、冷媒回路（30）内を冷媒が循環し、第１熱交換器（32）が凝縮器となり第２熱交換器（34）が蒸発器となる冷凍サイクルが行われる。第１熱交換器（32）では、第１空気と冷媒の間で熱交換が行われ、第１空気が加熱される。加熱された第１空気は、回転ロータ（40）へ送られる。   As shown in FIG. 2, room air is taken into the first passage (21) in the casing (1) as the first air. The first air taken into the first passage (21) is sent to the first heat exchanger (32). On the other hand, during operation of the compressor (31), the refrigerant circulates in the refrigerant circuit (30), and the first heat exchanger (32) serves as a condenser and the second heat exchanger (34) serves as an evaporator. A cycle is performed. In the first heat exchanger (32), heat exchange is performed between the first air and the refrigerant, and the first air is heated. The heated first air is sent to the rotating rotor (40).

回転ロータ（40）では、第１空気との接触によって、回転ロータ（40）の吸着剤から水分が脱離する。この脱離した水分は、第１空気に付与され、第１空気が加湿される。ここで、回転ロータ（40）の回転に伴い、第２空気中の水分を吸着した回転ロータ（40）の部分は、やがて第１通路（21）側へ移動して第１空気と接触する。この第１空気との接触によって、回転ロータ（40）の吸着剤から水分が脱離し、吸着剤の再生が行われる。そして、加熱され加湿された第１空気は、第１通路（21）を流れて空気吹出口を通過し、第２吹出口（13）から在室者から遠ざかる方向（ここでは、上方向）へ吹き出す。   In the rotary rotor (40), moisture is desorbed from the adsorbent of the rotary rotor (40) by contact with the first air. The desorbed moisture is given to the first air, and the first air is humidified. Here, with the rotation of the rotating rotor (40), the portion of the rotating rotor (40) that has adsorbed moisture in the second air eventually moves toward the first passage (21) and comes into contact with the first air. By the contact with the first air, moisture is desorbed from the adsorbent of the rotary rotor (40), and the adsorbent is regenerated. Then, the heated and humidified first air flows through the first passage (21), passes through the air outlet, and moves away from the occupant from the second outlet (13) (here, upward). Blow out.

一方、ケーシング（1）内の第２通路（22）へは、室内空気が第２空気として取り込まれる。第２通路（22）へ取り込まれた第２空気は、回転ロータ（40）へ送られる。回転ロータ（40）では、第２空気中の水分が吸着剤に吸着され、第２空気が除湿される。第２空気中の水分を吸着した回転ロータ（40）の部分は、やがて第１通路（21）側へ移動して第１空気と接触する。除湿された第２空気は、第２熱交換器（34）へ送られる。   On the other hand, indoor air is taken in as second air into the second passage (22) in the casing (1). The second air taken into the second passage (22) is sent to the rotating rotor (40). In the rotary rotor (40), moisture in the second air is adsorbed by the adsorbent, and the second air is dehumidified. The portion of the rotary rotor (40) that has adsorbed moisture in the second air eventually moves toward the first passage (21) and comes into contact with the first air. The dehumidified second air is sent to the second heat exchanger (34).

第２熱交換器（34）では、第２空気と冷媒の間で熱交換が行われ、第２空気が冷却される。そして、除湿され冷却された第２空気は、第２通路（22）を流れて空気吹出口を通過し、第１吹出口（12）から在室者の近傍（ここでは、図１における左方向）へ局所的に供給される。   In the second heat exchanger (34), heat exchange is performed between the second air and the refrigerant, and the second air is cooled. Then, the dehumidified and cooled second air flows through the second passage (22), passes through the air outlet, and passes from the first outlet (12) to the vicinity of the occupant (here, the left direction in FIG. 1). ) Locally.

本実施形態の空気調和装置において、冷媒回路（30）を流れる冷媒の蒸発温度は、回転ロータ（40）で除湿された後に第２熱交換器（34）を通過する第２空気の露点温度よりも高く設定されている。このため、第２熱交換器（34）を通過する第２空気は、常にその露点温度よりも高い温度に保たれる。従って、空気調和装置の運転中において、蒸発器となる第２熱交換器（34）ではドレン水が発生しない。   In the air conditioner of this embodiment, the evaporation temperature of the refrigerant flowing through the refrigerant circuit (30) is higher than the dew point temperature of the second air passing through the second heat exchanger (34) after being dehumidified by the rotary rotor (40). Is also set high. For this reason, the 2nd air which passes a 2nd heat exchanger (34) is always maintained at the temperature higher than the dew point temperature. Therefore, during operation of the air conditioner, drain water is not generated in the second heat exchanger (34) serving as an evaporator.

−実施形態１の効果−
本実施形態では、回転ロータ（40）の吸着剤に第２空気中の水分を吸着させることで第２空気を除湿し、その上で冷媒の蒸発温度を蒸発器となる第２熱交換器（34）を通過中の第２空気の露点温度よりも高く設定している。このため、空気調和装置では、第２空気の除湿が可能で、しかも蒸発器となる第２熱交換器（34）でのドレン水の発生を抑止することができる。従って、本実施形態によれば、空気調和装置の使い勝手を向上させることができる。 -Effect of Embodiment 1-
In the present embodiment, the second air is dehumidified by adsorbing the moisture in the second air to the adsorbent of the rotary rotor (40), and then the second heat exchanger (the evaporator is used as the evaporator). 34) is set higher than the dew point temperature of the second air passing through. For this reason, in the air conditioner, the dehumidification of the second air is possible, and the generation of drain water in the second heat exchanger (34) serving as an evaporator can be suppressed. Therefore, according to this embodiment, the usability of the air conditioner can be improved.

ここで、従来よりスポットクーラ等の室内に設置されて局所的な空調を行う空気調和装置には、蒸発器で発生するドレン水を処理するためのタンクが設けられていた。そして、このタンクがドレン水で一杯になると、ユーザーがタンクを取り外してドレン水を排出しなければならず、この点でも使い勝手が悪かった。   Here, conventionally, an air conditioner that is installed in a room such as a spot cooler and performs local air conditioning has been provided with a tank for treating drain water generated by an evaporator. When this tank was filled with drain water, the user had to remove the tank and drain the drain water, which was also unusable.

これに対し、本実施形態では、蒸発器となる第２熱交換器（34）でドレン水が発生しないため、ドレン水を処理するためのタンクを設ける必要がなくなる。従って、室内に設置されて局所的な空調を行う空気調和装置に本実施形態を適用することで、この種の空気調和装置の使い勝手を向上させることができる。   On the other hand, in this embodiment, since drain water does not generate | occur | produce in the 2nd heat exchanger (34) used as an evaporator, it becomes unnecessary to provide the tank for processing drain water. Therefore, the usability of this type of air conditioner can be improved by applying the present embodiment to an air conditioner that is installed indoors and performs local air conditioning.

《発明の実施形態２》
本発明の実施形態２は、上記実施形態１の空気調和装置の構成を変更したものである。ここでは、本実施形態について、上記実施形態１と異なる点を説明する。 << Embodiment 2 of the Invention >>
Embodiment 2 of this invention changes the structure of the air conditioning apparatus of the said Embodiment 1. FIG. Here, the difference between the present embodiment and the first embodiment will be described.

図４に示すように、本実施形態における空気調和装置の冷媒回路（30）には、冷凍サイクル中に蒸発器となる第３熱交換器（35）が設けられている。冷媒回路（30）では、圧縮機（31）、第１熱交換器（32）、膨張弁（33）、第２熱交換器（34）及び第３熱交換器（35）が、この順に直列に接続されている。つまり、第３熱交換器（35）は、第２熱交換器（34）よりも圧縮機（31）の吸入側に設けられている。また、第３熱交換器（35）は、第１通路（21）における回転ロータ（40）の下流側に設けられている。   As shown in FIG. 4, the refrigerant circuit (30) of the air conditioner according to the present embodiment is provided with a third heat exchanger (35) serving as an evaporator during the refrigeration cycle. In the refrigerant circuit (30), a compressor (31), a first heat exchanger (32), an expansion valve (33), a second heat exchanger (34), and a third heat exchanger (35) are arranged in this order. It is connected to the. That is, the third heat exchanger (35) is provided closer to the suction side of the compressor (31) than the second heat exchanger (34). The third heat exchanger (35) is provided on the downstream side of the rotary rotor (40) in the first passage (21).

第２熱交換器（34）において第２空気と熱交換された冷媒は、第３熱交換器（35）へと流れる。第３熱交換器（35）において、回転ロータ（40）を通過後の第１空気と冷媒回路（30）を流れる冷媒との間で熱交換が行われ、第１空気が冷却される。そして、冷却された第１空気は、第２吹出口（13）から在室者から遠ざかる方向へ吹き出す。   The refrigerant that has exchanged heat with the second air in the second heat exchanger (34) flows to the third heat exchanger (35). In the third heat exchanger (35), heat exchange is performed between the first air that has passed through the rotary rotor (40) and the refrigerant that flows through the refrigerant circuit (30), thereby cooling the first air. And the cooled 1st air blows off in the direction away from a occupant from a 2nd blower outlet (13).

本実施形態では、冷媒回路（30）に蒸発器となる第２熱交換器（34）に加えて蒸発器となる第３熱交換器（35）が設けられている。このため、第２熱交換器（34）における第２空気からの熱回収量と第３熱交換器（35）における第１空気からの熱回収量の割合を自由に調整することができる。従って、本実施形態によれば、空気調和装置の運転能力の調整を容易に行うことができる。   In the present embodiment, the refrigerant circuit (30) is provided with a third heat exchanger (35) serving as an evaporator in addition to the second heat exchanger (34) serving as an evaporator. For this reason, the ratio of the heat recovery amount from the second air in the second heat exchanger (34) and the heat recovery amount from the first air in the third heat exchanger (35) can be freely adjusted. Therefore, according to the present embodiment, it is possible to easily adjust the operating capacity of the air conditioner.

また、本実施形態では、第３熱交換器（35）において、加湿され加熱された第１空気を冷媒と熱交換させることにより、第１空気の温度が低下する。ここで、加湿され加熱された第１空気を在室者から遠ざかる方向に吹き出す場合において、第１空気が通路へ向かって吹き出されると、この通路を通る人に不快感を与えることになる。また、本実施形態の空気調和装置とは別の空調機で室内全体の冷房を行っている場合において、加湿され加熱された第１空気の吹き出し方向に空調機の吸込口が設けられていると、第１空気がこの吸込口から空調機の内部に吸い込まれ、空調機の負荷が過大となるおそれがある。   Moreover, in this embodiment, in the 3rd heat exchanger (35), the temperature of 1st air falls by carrying out heat exchange of the humidified and heated 1st air with a refrigerant | coolant. Here, in the case where the humidified and heated first air is blown away in a direction away from the occupant, if the first air is blown out toward the passage, the person passing through the passage is uncomfortable. Further, in the case where the entire room is cooled by an air conditioner different from the air conditioner of the present embodiment, the air inlet of the air conditioner is provided in the blowing direction of the humidified and heated first air. The first air is sucked into the air conditioner from the suction port, and the load on the air conditioner may be excessive.

従って、本実施形態によれば、第３熱交換器（35）を設けて第１空気の温度を低下させることにより、高い温度の第１空気が空調機の吸込口から吸い込まれて空調機の負荷が過大となることを防止でき、空気調和装置の設置自由度を高めることができる。   Therefore, according to this embodiment, by providing the third heat exchanger (35) to reduce the temperature of the first air, the first air having a high temperature is sucked from the air inlet of the air conditioner and the air conditioner An excessive load can be prevented, and the degree of freedom of installation of the air conditioner can be increased.

−実施形態２の変形例−
上記実施形態２の空気調和装置において、冷媒回路（30）の構成を変更してもよい。ここでは、本変形例について、上記実施形態２と異なる点を説明する。 -Modification of Embodiment 2-
In the air conditioning apparatus of the second embodiment, the configuration of the refrigerant circuit (30) may be changed. Here, this modification will be described while referring to differences from the second embodiment.

まず、図５に示すように、冷媒回路（30）における膨張弁（33）の下流側に、第２熱交換器（34）と第３熱交換器（35）とを並列に設けてもよい。具体的に、冷媒回路（30）では、膨張弁（33）の下流側が２つの回路に分岐し、このうち一方の回路には第２熱交換器（34）が、他方の回路には第３熱交換器（35）が設けられている。また、膨張弁（33）の下流側で２つに分岐した回路は、圧縮機（31）の手前で合流している。   First, as shown in FIG. 5, the second heat exchanger (34) and the third heat exchanger (35) may be provided in parallel on the downstream side of the expansion valve (33) in the refrigerant circuit (30). . Specifically, in the refrigerant circuit (30), the downstream side of the expansion valve (33) branches into two circuits, one of which is the second heat exchanger (34) and the other circuit is the third. A heat exchanger (35) is provided. Moreover, the circuit branched into two on the downstream side of the expansion valve (33) is joined before the compressor (31).

冷媒回路（30）を流れる冷媒は、膨張弁（33）を通過後、２つに分岐した回路のそれぞれに流入する。そして、一方の回路では、第２熱交換器（34）において、回転ロータ（40）を通過後の除湿された第２空気と冷媒との間で熱交換が行われる。他方の回路では、第３熱交換器（35）において、回転ロータ（40）を通過後の加湿された第１空気と冷媒との間で熱交換が行われる。   The refrigerant flowing through the refrigerant circuit (30) flows into each of the two branched circuits after passing through the expansion valve (33). In one circuit, the second heat exchanger (34) performs heat exchange between the dehumidified second air after passing through the rotary rotor (40) and the refrigerant. In the other circuit, in the third heat exchanger (35), heat is exchanged between the humidified first air after passing through the rotary rotor (40) and the refrigerant.

次に、図６に示すように、冷媒回路（30）における第１熱交換器（32）の下流側に、第２熱交換器（34）と第３熱交換器（35）とを並列に設けてもよい。具体的に、冷媒回路（30）では、第１熱交換器（32）の下流側が２つの回路に分岐し、このうち一方の回路には第２熱交換器（34）が、他方の回路には第３熱交換器（35）が設けられている。また、２つに分岐した回路では、一方の回路における第２熱交換器（34）の上流側に膨張弁（33）が、他方の回路における第３熱交換器（35）の上流側に膨張弁（36）がそれぞれ設けられている。それぞれの回路に設けられる膨張弁（33,36）の開度を調節すると、各回路を流れる冷媒の流量が変化し、第２熱交換器（34）や第３熱交換器（35）における空気と冷媒との熱交換量が変化する。   Next, as shown in FIG. 6, the second heat exchanger (34) and the third heat exchanger (35) are arranged in parallel on the downstream side of the first heat exchanger (32) in the refrigerant circuit (30). It may be provided. Specifically, in the refrigerant circuit (30), the downstream side of the first heat exchanger (32) branches into two circuits, one of which is the second heat exchanger (34) and the other is the circuit. Is provided with a third heat exchanger (35). Further, in the circuit branched into two, the expansion valve (33) is expanded upstream of the second heat exchanger (34) in one circuit, and is expanded upstream of the third heat exchanger (35) in the other circuit. Each valve (36) is provided. When the opening degree of the expansion valve (33, 36) provided in each circuit is adjusted, the flow rate of the refrigerant flowing through each circuit changes, and the air in the second heat exchanger (34) and the third heat exchanger (35) The amount of heat exchange between the refrigerant and the refrigerant changes.

図７，８に示すように、本実施形態の空気調和装置は、冷媒回路（30）と２つの吸着素子（81,82）とを備えている。この空気調和装置は、いわゆるバッチ式の動作を行う。具体的には、第１吸着素子（81）で再生動作を行って第２吸着素子（82）で吸着動作を行う運転と、第１吸着素子（81）で吸着動作を行って第２吸着素子（82）で再生動作を行う運転とを交互に繰り返す。   As shown in FIGS. 7 and 8, the air conditioner of the present embodiment includes a refrigerant circuit (30) and two adsorbing elements (81, 82). This air conditioner performs a so-called batch operation.

In the second operation, the second air is dehumidified by the second adsorption element (82), and the adsorbent of the first adsorption element (81) is regenerated. As shown in FIG. 8, the second air taken into the casing (1) by driving the fan flows into the humidity adjusting side passageway (85) of the second adsorption element (82). While flowing through the humidity adjusting side passageway (85), moisture in the second air is adsorbed by the adsorbent. The second air dehumidified by the second adsorption element (82) is sent to the second heat exchanger (34). In the second heat exchanger (34), heat exchange is performed between the second air and the refrigerant, and the second air is cooled. Then, the dehumidified and cooled second air is locally supplied to the vicinity of the occupant.

一方、ファンを駆動してケーシング（1）内に取り込まれた第１空気は、第２吸着素子（82）の冷却側通路（86）へ流入する。この冷却側通路（86）を流れる間に、第１空気は、調湿側通路（85）で第２空気中の水分が吸着剤に吸着される際に生じた吸着熱を吸熱する。吸着熱を奪った第１空気は、第１熱交換器（32）を通過する。その際、第１熱交換器（32）では、第１空気が冷媒との熱交換によって加熱される。   On the other hand, the first air taken into the casing (1) by driving the fan flows into the cooling side passage (86) of the second adsorption element (82). While flowing through the cooling side passage (86), the first air absorbs heat of adsorption generated when moisture in the second air is adsorbed by the adsorbent in the humidity adjustment side passage (85). The first air deprived of the heat of adsorption passes through the first heat exchanger (32). At that time, in the first heat exchanger (32), the first air is heated by heat exchange with the refrigerant.

第２吸着素子（82）及び第１熱交換器（32）で加熱された第１空気は、第１吸着素子（81）の調湿側通路（85）へ導入される。この調湿側通路（85）では、第１空気によって吸着剤が加熱され、吸着剤から水分が脱離する。つまり、第１吸着素子（81）の再生が行われる。吸着剤から脱離した水分は、第１空気に付与される。そして、加熱され加湿された第１空気は、在室者から遠ざかる方向へ吹き出す。   The 1st air heated with the 2nd adsorption element (82) and the 1st heat exchanger (32) is introduced into the humidity control side channel (85) of the 1st adsorption element (81). In the humidity adjusting side passageway (85), the adsorbent is heated by the first air, and moisture is desorbed from the adsorbent. That is, the regeneration of the first adsorption element (81) is performed. The moisture desorbed from the adsorbent is given to the first air.

《発明の実施形態４》
本発明の実施形態４は、上記実施形態１の空気調和装置の構成を変更したものである。ここでは、本実施形態について、上記実施形態１と異なる点を説明する。 << Embodiment 4 of the Invention >>
Embodiment 4 of this invention changes the structure of the air conditioning apparatus of the said Embodiment 1. FIG. Here, the difference between the present embodiment and the first embodiment will be described.

図１０に示すように、本実施形態の空気調和装置では、冷媒回路（30）に四路切換弁（37）が設けられている。四路切換弁（37）は、その第１ポートが圧縮機（31）の吐出側に、その第２ポートが第２熱交換器（34）に、その第３ポートが圧縮機（31）の吸入側に、その第４ポートが第１熱交換器（32）にそれぞれ接続されている。   As shown in FIG. 10, in the air conditioner of this embodiment, the refrigerant circuit (30) is provided with a four-way switching valve (37). The four-way selector valve (37) has a first port on the discharge side of the compressor (31), a second port on the second heat exchanger (34), and a third port on the compressor (31). On the suction side, the fourth ports are connected to the first heat exchanger (32), respectively.

そして、四路切換弁（37）を、その第１ポートと第４ポートとが接続してその第２ポートと第３ポートとが接続する状態（図１０に実線で示す状態）に切り換えると、冷媒回路（30）では第１熱交換器（32）が凝縮器となり第２熱交換器（34）が蒸発器となる冷凍サイクルが行われる。また、四路切換弁（37）を、その第１ポートと第２ポートとが接続してその第３ポートと第４ポートとが接続する状態（図１０に破線で示す状態）に切り換えると、冷媒回路（30）では第２熱交換器（34）が凝縮器となり第１熱交換器（32）が蒸発器となる冷凍サイクルが行われる。   Then, when the four-way switching valve (37) is switched to a state in which the first port and the fourth port are connected and the second port and the third port are connected (indicated by a solid line in FIG. 10), In the refrigerant circuit (30), a refrigeration cycle is performed in which the first heat exchanger (32) serves as a condenser and the second heat exchanger (34) serves as an evaporator. Further, when the four-way switching valve (37) is switched to a state where the first port and the second port are connected and the third port and the fourth port are connected (state indicated by a broken line in FIG. 10), In the refrigerant circuit (30), a refrigeration cycle in which the second heat exchanger (34) serves as a condenser and the first heat exchanger (32) serves as an evaporator is performed.

上記冷媒回路（30）において、第１熱交換器（32）及び第２熱交換器（34）を構成する伝熱管及びフィン（図示せず）の表面には、吸着剤としてのゼオライトが担持されている。   In the refrigerant circuit (30), zeolite as an adsorbent is supported on the surfaces of heat transfer tubes and fins (not shown) constituting the first heat exchanger (32) and the second heat exchanger (34). ing.

−運転動作−
まず、四路切換弁（37）が図１０に実線で示す状態において、冷媒回路（30）では第１熱交換器（32）が凝縮器となり第２熱交換器（34）が蒸発器となる冷凍サイクルが行われる。また、第１通路（21）には第１空気が取り込まれ、第２通路（22）には第２空気が取り込まれる。 -Driving action-
First, in a state where the four-way switching valve (37) is shown by a solid line in FIG. 10, in the refrigerant circuit (30), the first heat exchanger (32) becomes a condenser and the second heat exchanger (34) becomes an evaporator. A refrigeration cycle is performed. Moreover, 1st air is taken in into a 1st channel | path (21), and 2nd air is taken in into a 2nd channel | path (22).

第１熱交換器（32）の伝熱管及びフィンに担持された吸着剤は、伝熱管内を流れる冷媒により加熱され、吸着剤から水分が脱離する。第１通路（21）を流れる第１空気は、第１熱交換器（32）において、伝熱管内を流れる冷媒により加熱される。吸着剤から脱離した水分は、第１空気に付与される。そして、第１熱交換器（32）で加熱され加湿された第１空気は、在室者から遠ざかる方向へ吹き出す。   The adsorbent carried on the heat transfer tubes and fins of the first heat exchanger (32) is heated by the refrigerant flowing in the heat transfer tubes, and moisture is desorbed from the adsorbents. The first air flowing through the first passage (21) is heated by the refrigerant flowing through the heat transfer tube in the first heat exchanger (32). The moisture desorbed from the adsorbent is given to the first air. And the 1st air heated and humidified by the 1st heat exchanger (32) blows off in the direction away from a resident.

一方、第２通路（22）へ取り込まれた第２空気は、第２熱交換器（34）において、それに含まれる水分が伝熱管やフィンに担持された吸着剤に吸着されて除湿される。その際に生じる吸着熱は、伝熱管内を流れる冷媒に吸熱される。また、第２熱交換器（34）を通過する第２空気から冷媒が吸熱する。そして、第２熱交換器（34）で除湿され冷却された第２空気は、在室者の近傍へ局所的に供給される。   On the other hand, the second air taken into the second passage (22) is dehumidified in the second heat exchanger (34) by the moisture contained therein being adsorbed by the adsorbent carried on the heat transfer tubes and fins. The adsorption heat generated at that time is absorbed by the refrigerant flowing in the heat transfer tube. Further, the refrigerant absorbs heat from the second air passing through the second heat exchanger (34). Then, the second air dehumidified and cooled by the second heat exchanger (34) is locally supplied to the vicinity of the occupant.

このように、第１熱交換器（32）の吸着剤が再生される一方、第２熱交換器（34）の吸着剤に第２空気中の水分が吸着される。そして、第２熱交換器（34）の吸着剤が第２空気中の水分を吸着して飽和すると、四路切換弁（37）が切り換わる。   Thus, while the adsorbent of the first heat exchanger (32) is regenerated, the moisture in the second air is adsorbed by the adsorbent of the second heat exchanger (34). Then, when the adsorbent of the second heat exchanger (34) adsorbs moisture in the second air and is saturated, the four-way switching valve (37) is switched.

次に、四路切換弁（37）が図１０に破線で示す状態に切り換わると、冷媒回路（30）では第２熱交換器（34）が凝縮器となり第１熱交換器（32）が蒸発器となる冷凍サイクルが行われる。また、第１通路（21）には第２空気が取り込まれ、第２通路（22）には第１空気が取り込まれる。   Next, when the four-way selector valve (37) is switched to the state indicated by the broken line in FIG. 10, the second heat exchanger (34) becomes a condenser in the refrigerant circuit (30), and the first heat exchanger (32) A refrigeration cycle that serves as an evaporator is performed. Further, the second air is taken into the first passage (21), and the first air is taken into the second passage (22).

第２熱交換器（34）の伝熱管及びフィンに担持された吸着剤は、伝熱管内を流れる冷媒により加熱され、吸着剤から水分が脱離する。第２通路（22）を流れる第１空気は、第２熱交換器（34）において、伝熱管内を流れる冷媒により加熱される。吸着剤から脱離した水分は、第１空気に付与される。そして、第２熱交換器（34）で加熱され加湿された第１空気は、在室者から遠ざかる方向へ吹き出す。   The adsorbent carried on the heat transfer tubes and fins of the second heat exchanger (34) is heated by the refrigerant flowing in the heat transfer tubes, and moisture is desorbed from the adsorbents. The first air flowing through the second passage (22) is heated by the refrigerant flowing through the heat transfer tube in the second heat exchanger (34). The moisture desorbed from the adsorbent is given to the first air. And the 1st air heated and humidified by the 2nd heat exchanger (34) blows off in the direction away from a resident.

一方、第１通路（21）へ取り込まれた第２空気は、第１熱交換器（32）において、それに含まれる水分が伝熱管やフィンに担持された吸着剤に吸着されて除湿される。その際に生じる吸着熱は、伝熱管内を流れる冷媒に吸熱される。また、第１熱交換器（32）を通過する第２空気から冷媒が吸熱する。そして、第１熱交換器（32）で除湿され冷却された第２空気は、在室者の近傍へ局所的に供給される。   On the other hand, the second air taken into the first passage (21) is dehumidified in the first heat exchanger (32) by the moisture contained therein being adsorbed by the adsorbent carried on the heat transfer tubes and fins. The adsorption heat generated at that time is absorbed by the refrigerant flowing in the heat transfer tube. Further, the refrigerant absorbs heat from the second air passing through the first heat exchanger (32). Then, the second air dehumidified and cooled by the first heat exchanger (32) is locally supplied to the vicinity of the occupant.

このように、第２熱交換器（34）の吸着剤が再生される一方、第１熱交換器（32）の吸着剤に第２空気中の水分が吸着される。そして、第１熱交換器（32）の吸着剤が第２空気中の水分を吸着して飽和すると、四路切換弁（37）が切り換わる。   Thus, while the adsorbent of the second heat exchanger (34) is regenerated, the moisture in the second air is adsorbed by the adsorbent of the first heat exchanger (32). When the adsorbent of the first heat exchanger (32) adsorbs moisture in the second air and is saturated, the four-way switching valve (37) is switched.
