Abstract

It is possible to improve convergence of performance control in a freezing device which performs a super-critical cycle. An air conditioner (10) includes: a coolant circuit (20) in which a compressor (21), an outdoor heat exchanger (23), an outdoor expansion valve (24), and an indoor exchanger (27) are connected in this order so as to perform a super-critical freezing cycle having a high pressure exceeding the critical pressure of a coolant; and a controller (40) having at least a compressor (21) and an outdoor expansion valve (24) for controlling a control object. The controller (40) controls a plurality of control objects all together so as to control both of a predetermined physical amount and a freezing cycle high pressure as indexes of the performance of the freezing device.
