Claims

[Scope of utility model registration request]

A refrigeration cycle consisting of a compressor, an indoor heat exchanger, an electric expansion valve whose opening changes depending on the number of pulses applied, an indoor heat exchanger, etc., and a superheat system for this refrigeration cycle. a detection means for detecting the amount of superheat, and when the detection result of this detection means is within a certain range with respect to the set target amount of superheat, a number of pulses is generated that is approximately proportional to the difference between the detection result and the set target amount of superheat. and a control means for applying a certain number of pulses to the electric expansion valve when the detection result is outside a certain range with respect to the set target superheat amount. air conditioner.
