ル装置。 A refrigeration cycle consisting of a variable rotation speed compressor, a condenser, an electric expansion valve whose throttling amount can be adjusted by an electric signal, and an evaporator are connected in sequence, a detection means for detecting the state of this refrigeration cycle, and a a first means for setting the opening degree of the electric expansion valve so as to be approximately proportional to the rotational speed of the variable number compressor; and an appropriate amount of superheat depending on the state of the refrigeration cycle detected by the detection means and a second means for finely adjusting the opening degree of the electric expansion valve during overload operation of the variable rotation speed compressor. A refrigeration cycle device comprising a control device that outputs an electric signal to adjust the throttle amount of the electric expansion valve.
