Claims (1)

[Scope of utility model registration request] A compressor, a four-way valve, an indoor heat exchanger, an outdoor heat exchanger, an endothermic heat exchanger that absorbs heat during operation of an external heat source heat pump that uses an external heat source such as combustion heat, and performs gas-liquid separation of the refrigerant. An air conditioner in which an accumulator, a solenoid valve, a check valve, a capillary tube for heating, a capillary tube for cooling, etc. are connected by refrigerant piping, and the amount of refrigerant required in the accumulator or cooling operation, and the amount required in an air source heat pump. An air conditioner characterized by having a volume that can accommodate, in liquid refrigerant, an amount of refrigerant equal to the difference between the maximum amount of refrigerant and the minimum amount of refrigerant among the amount of refrigerant and the amount of refrigerant required during operation of an external heat source heat pump.
