気調和機。[Claims for Utility Model Registration] A refrigeration cycle is formed by sequentially connecting a compressor, a condenser, an expansion valve, and an evaporator, and the expansion valve is opened based on the refrigerant temperature on the inlet side and the refrigerant temperature on the outlet side of the evaporator. In an air conditioner that adjusts temperature, there is a condenser side air temperature sensor that detects the air temperature on the condenser side, an evaporator side air temperature sensor that detects the evaporator side air temperature, and a condenser side air temperature sensor that detects the air temperature on the evaporator side. and an appropriate expansion valve opening output means that obtains an appropriate expansion valve opening based on the evaporator side air temperature and the evaporator side air temperature. 1. An air conditioner comprising: a refrigerant amount determining means that outputs a refrigerant amount shortage signal when the refrigerant amount is insufficient.
