トポンプ装置。 In a heat pump device in which refrigerant discharged from a compressor circulates through a condenser, an electronic expansion valve, and an evaporator in this order, a temperature sensor detects the temperature of the refrigerant sucked into the compressor, and a refrigerant evaporates in the evaporator. A temperature sensor that detects temperature, a calculator that calculates the difference between the detected values of both temperature sensors, and a fuzzy theoretical calculation based on the control rule based on the calculated value of this calculator to calculate the opening degree of the electronic expansion valve. A heat pump device comprising a calculation means.
