Claims

[Scope of utility model registration request]

In an air conditioner equipped with a refrigeration cycle, an air temperature sensor is provided near the air inlet of the cooler, a refrigerant temperature sensor is attached to the refrigerant outlet pipe of the cooler, and defrosting is performed based on the temperature difference between the surface temperature sensors. When the temperature setting value is reached, a two-way valve attached to a bypass leading to the cooler is opened to supply a part of the refrigerant from the refrigerant compressor to the cooler for defrosting. Air conditioner.
