A degree-of-superheat control unit (44) is configured to adjust the degree of opening of an indoor expansion valve (26) based on a control gain for determining an opening-degree adjustment amount of the indoor expansion valve (26), and includes a control-gain determination unit (41) configured to increase a control gain g when the target-degree-of-superheat determination unit (39) increases a target degree of superheat SHs and to reduce the control gain g when the target-degree-of-superheat determination unit (39) reduces the target degree of superheat SHs. |
