ポンプ式空気調和機。 A heating cycle is formed by the compressor 1, the utilization side coil 5, the pressure reducer 4, and the heat source side coil 3 that exchanges heat with the outside air, and a discharge port connects the discharge port of the compressor 1 and the heating inlet of the utilization side coil 5. Gas main pipe 7
A hot gas bypass pipe 8 is provided which branches off from the user side coil 5 and the pressure reducer 4 and is connected to the heating inlet of the heat source side coil 3. In a heat pump type air conditioner having a solenoid valve 9 interposed therebetween, an electric expansion valve is used as the pressure reducer 4, and a frost detection means 10 detects a frost state of the heat source side coil 3 and issues a defrosting command.
and a pressure reducer control means 11 that is activated by a defrosting command issued by the frost detection means 10 to increase the valve opening of the pressure reducer 4 for a predetermined period of time to fully close it.
A heat pump type air conditioner characterized in that it is provided with a solenoid valve control means 12 that opens the solenoid valve 9 after the pressure reducer control means 11 finishes operating and closes it by defrosting.
