てある。 Circuit 7 between the four-way valve 2 and the water/refrigerant heat exchanger 4
A refrigerant/refrigerant heat exchanger 9 is interposed between the air/refrigerant heat exchanger 3 and the circuit 8 between the expansion valve 5 and the refrigerant passing through both circuits 7 and 8 to exchange heat with each other.
Three-way valves 7' and 8' are interposed in the circuits connecting the refrigerant/refrigerant heat exchanger 9 and the circuits 7 and 8, respectively.
上記構成における作用を以下に説明する。 The operation of the above configuration will be explained below.

る。(2) During defrosting (Fig. 4) The circuit leading to the refrigerant/refrigerant heat exchanger 9 is opened, and the high temperature refrigerant on the discharge side from the compressor 1 is exchanged with the air/refrigerant whose temperature has decreased through the expansion valve 5. The temperature of the refrigerant entering the air-refrigerant heat exchanger 3 is increased by exchanging heat with the refrigerant on the inlet side of the air-refrigerant heat exchanger 3. This melts the frost and ice formed on the surface of the evaporator of the air/refrigerant heat exchanger 3.
このときの暖房は若干その機能は低下するが暖
房状態が維持される。 At this time, the heating function is slightly reduced, but the heating state is maintained.
