本発明はそれぞれ運転、停止のできる室内機を複数台備
えたヒートポンプ式暖房装置C:関するものである。DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a heat pump type heating apparatus C equipped with a plurality of indoor units, each of which can be started and stopped.
この種の装置C二おいて、運転を停止している室内機が
ある状態で運転を行うと、運転を停止している室内機の
凝縮器内区:高温高圧のガスが浸入し凝縮器からの放熱
ζ:より液化し、凝縮器内は冷媒の液溜りとなり、その
結果システム内の冷媒循環量が不足し、暖房能力が減じ
る。If this type of device C2 is operated with an indoor unit that is not operating, high-temperature, high-pressure gas will enter the condenser section of the indoor unit that is not operating, and from the condenser. Heat dissipation ζ: The refrigerant becomes more liquefied and becomes a pool of refrigerant inside the condenser, resulting in insufficient refrigerant circulation within the system and reduced heating capacity.
そこで、一般(=は停止室内機から圧縮機の吸入側へバ

り、ひいては寿命の低下要因にもなる。Therefore, in general, a bypass circuit is installed from the stopped indoor unit to the suction side of the compressor, and the differential pressure between the two is used to return liquid refrigerant from the stopped indoor unit to the compressor suction side. Because of the compression, the mechanical efficiency of the compressor deteriorates, which in turn causes a reduction in the life of the compressor.
一方、停止室内機から圧縮機吸入側以外へのバイパス、
たとえば室外側熱交換器へ戻す手段がある。この手段は
暖房能力低下防止に有効であるが、スーパーヒート気味

かりか、圧縮機用モータの絶縁不良およびコイル焼損等
の原因C;もなる。On the other hand, bypass from the stopped indoor unit to other than the compressor suction side,
For example, there is a means for returning the heat to the outdoor heat exchanger. Although this method is effective in preventing a decrease in heating capacity, it often results in a slightly superheated state, which not only causes an increase in the temperature of the discharged gas, but also causes poor insulation of the compressor motor and burnout of the coil.

C:戻すようにしたものである。The present invention has been made to improve these drawbacks. Depending on the degree of wet compression, the present invention has a cooling effect that suppresses the temperature of the discharged gas, and conversely becomes a factor in improving energy efficiency. Particularly, depending on the discharge gas temperature of the compressor 1, the liquid refrigerant in the stopped indoor unit is returned to the evaporator or the compressor C.
以下、本発明を図C二示す一実施例(二より説明する。Hereinafter, the present invention will be explained starting from an embodiment shown in Figure C2.

出管路に設けたサーモスタット8によって制卸される。, 1 is a compressor, 2 is a condenser, 3 is a throttle device, and 4 is an evaporator. 5 is a solenoid valve. There are three condensers 2 and three sets of solenoid valves 5. Reference numeral 6 denotes a capillary, which is connected to the outlet side of each condenser 2, respectively. The other end is connected to the inlet side of the evaporator 4 or the inlet side of the compressor 1 via the three-way valve 7. The three-way valve 7 is controlled by a thermostat 8 provided at the head of the compressor 1 or in the discharge pipe of the compressor 1.
スパーヒート気味になり、圧縮1機1の吐出ガス温度が
高くなるとサーモスタット8は三方弁7の流路を圧縮f
i1の吸入側へ開放するように動作する。When the temperature of the gas discharged from the compressor 1 increases due to the superheating, the thermostat 8 compresses the flow path of the three-way valve 7.
It operates to open to the suction side of i1.

足は解消され、暖房能力低下は防止される。In this configuration (2), since the temperature of the gas refrigerant in the compressor 1 is low, the conduit is connected to the evaporator 4 side, which is the flow path of the three-way valve 7, by the thermostat 8. Therefore, the condenser 2 of the stopped indoor unit
The liquid refrigerant is drawn into the evaporator 4. This eliminates the refrigerant shortage and prevents a decrease in heating capacity.

弁7は流路な圧縮機1の吸入側に接続スる。この液冷媒
(=より圧縮機1は冷媒され、吐出ガス温度は低下する
。吐出ガス温度が低ドすると三方弁は元に戻る。However, when the temperature of the gas discharged from the compressor 1 inevitably becomes too hot due to the superheating, the thermostat 8 is activated and the three-way valve 7 is connected to the suction side of the compressor 1, which is a flow path. From this liquid refrigerant (=), the compressor 1 is refrigerated, and the temperature of the discharged gas decreases. When the temperature of the discharged gas decreases, the three-way valve returns to its original state.
この上うC:;吐出ガス温度の上昇及び湿り圧縮を可能
な限り防止するよう監ニジているので、圧縮機1の寿命
低下を防止できるものである。Furthermore, since the discharge gas temperature rise and wet compression are supervised to be prevented as much as possible, shortening of the life of the compressor 1 can be prevented.

防止できると共に冷媒の不足を防止できるものである。As described in 1 above, the present invention returns the liquid refrigerant in the stopped indoor unit to the evaporator when the discharge gas temperature of the compressor is low, and returns it to the compressor when the temperature is high, thereby extending the life of the compressor. It is possible to prevent a decrease in the refrigerant and also to prevent a shortage of refrigerant.

Connect each capillary, and connect the other end of the capillary to the inlet side of the evaporator or the inlet side of the compressor via a three-way valve. However, the three-way valve opens the flow path to the inlet side of the evaporator when the discharge gas temperature of the compressor is lower than a predetermined temperature, and to the outlet of the compressor when the temperature is higher than the predetermined temperature. - A heat pump type multi-room heating device characterized by:
