The heat exchanger on the non-use side installed outside, 5/' and 6' are the first and second pressure reducing devices, and 7' is a three-way switching valve device that is automatically switched depending on the room temperature.When the room temperature is high, the refrigerant is switched by the solid arrow. Like <1'-7'-4
Main use side heat exchanger 3' flows in the order of '-5'-2'-1'
The indoor air is dehumidified and cooled, and when the room temperature becomes low, the valve device 7' is switched and the refrigerant flows as shown by the dashed arrow.<1'-7'-3'-6'-2'-1 ' The flow is dehumidified and cooled in the main use side heat exchanger 2', then reheated in the auxiliary use side heat exchanger 3' to perform heating and dehumidification. When the temperature rises again, the above-mentioned cooling dehumidification is performed, and the room temperature is is kept approximately constant.

を生じ易いという欠点がある。However, in such a dehumidifying device, the cooling capacity of the main use side heat exchanger 2' during cooling dehumidification is large, and the heating capacity of the auxiliary use side heat exchanger 2' during heating dehumidification is large, so that the indoor temperature changes rapidly. Therefore, the switching of the three-way switching valve device 7' becomes frequent, which shortens the life of the valve device 7' and makes it more likely to break down.
本案は斯る欠点に鑑みてなされたもので、第２図に従い
その実施例を説明する。The present invention has been developed in view of these drawbacks, and an embodiment thereof will be described with reference to FIG.

構成するようにしている。1 is a refrigerant compressor, 7 is a four-way switching valve device, 5 is a pressure reducing device such as an expansion valve, 3 is a main use side heat exchanger installed indoors, and 2 is the leeward side of this main use side heat exchanger. 4 is a non-use side heat exchanger installed on the outdoor side, compressor 1, main use side heat exchanger 3, pressure reducing device 5, both ends a, a of series circuit A. ', auxiliary use side heat exchanger 2,
Both ends of the series circuit B of the heat exchanger 4 on the non-use side are connected via a switching valve device 7 that can be switched depending on the room temperature,
When the room temperature is high, the compressor 1, switching valve device 7, non-use side heat exchanger 4, auxiliary use side heat exchanger 2, switching valve device 7, pressure reducing device 5, main use side heat exchanger 3, compressor 1 When the room temperature is low, compressor 1 is connected to
Switching valve device 7, auxiliary use side heat exchanger 2, non-use side heat exchanger 4, switching valve device 7, pressure reduction device 5, main use side heat exchanger 3
, and the compressor 1 to form a dehumidifying and heating operation circuit which is sequentially connected in an annular manner.
又、８は利用側熱交換器２，３に室内空気を送風する利
用側送風機、９は非利用側熱交換器４に室外空気を送風
する非利用側送風機である。Further, 8 is a usage side blower that blows indoor air to the usage side heat exchangers 2 and 3, and 9 is a non-use side blower that blows outdoor air to the non-use side heat exchanger 4.
そして、室内温度が高い時には図示しない温度調整器に

、非利用側熱交換器４で多量放熱し、補助利用側熱交換
器２で小熱量放熱した後、減圧装置５で減圧され主利用
側熱交換器３で蒸発する。When the indoor temperature is high, the valve device 7 is switched to the state shown by the solid line by a temperature regulator (not shown), and the refrigerant flows in the order of 1-7-4-2-7-5-3-1 as shown by the solid line arrows. After a large amount of heat is radiated in the non-use side heat exchanger 4 and a small amount of heat is radiated in the auxiliary use side heat exchanger 2, the pressure is reduced in the pressure reducing device 5 and evaporated in the main use side heat exchanger 3.
従って、室内空気は主利用側熱交換器３で除湿冷却され
た後、補助利用側熱交換器２にて少量加熱されるので、
除湿弱冷却作用がなされる。Therefore, after the indoor air is dehumidified and cooled in the main use side heat exchanger 3, it is heated a small amount in the auxiliary use side heat exchanger 2.
A dehumidifying and weak cooling effect is performed.
この冷却作用により室温が低くなると、弁装置７は破線
の状態に切換えられ熱交換器２，４に於ける冷媒の流れ
が逆転する。When the room temperature becomes lower due to this cooling effect, the valve device 7 is switched to the state shown by the broken line, and the flow of the refrigerant in the heat exchangers 2 and 4 is reversed.
即ち、冷媒は破線矢視の如＜ １−７−２−４−７−５
−３−１の順に流れ、補助利用側熱交換器２で多量放熱
し、非利用側熱交換器４で少量放熱した後減圧装置５で
減圧され主利用側熱交換器３で蒸発する。That is, the refrigerant is
-3-1, a large amount of heat is radiated in the auxiliary use side heat exchanger 2, a small amount of heat is radiated in the non-use side heat exchanger 4, the pressure is reduced in the pressure reducing device 5, and the heat is evaporated in the main use side heat exchanger 3.
従って、室内空気は主利用側熱交換器３で除湿冷却され

湿弱加熱作用がなされる。Therefore, after the indoor air is dehumidified and cooled by the main use side heat exchanger 3, it is heated to a large extent by the auxiliary use side heat exchanger 2, so that a dehumidifying and weak heating effect is performed.
尚、非利用側送風機９は外気温によってその送風量を制

く、低い時は少くするものである。It is preferable that the amount of air blown by the unused side blower 9 is controlled depending on the outside temperature. For example, when the outside temperature is high, the amount of air blown is increased, and when the outside temperature is low, the amount of air blown is decreased.

て除湿弱加熱運転がなされる。As described above, the present invention is structured so that when the indoor temperature is high, the cooling effect of the main use side heat exchanger 3 is weakened by the small amount of heating effect of the auxiliary use side heat exchanger 2, so the dehumidification effect is lower than that of the conventional device. A weak cooling operation is performed, and when the indoor temperature is low, the heating effect of the auxiliary use side heat exchanger 2 is also radiated a small amount of heat to the non-use side heat exchanger 4, so the dehumidifying weak heating operation is possible compared to the conventional device. will be done.
