Claims

[Scope of utility model registration request]

In a refrigeration cycle constructed by sequentially connecting a compressor, a condenser, an expansion valve, and an evaporator, first and second sensors detect the refrigerant temperature on the refrigerant inlet side and refrigerant outlet side of the evaporator or condenser. A temperature sensor is provided, the temperatures detected by the first and second temperature sensors are compared, and a gas leak signal is generated when the temperature difference continues to be below a set value or above a set value. Air conditioner.
