<p>In a refrigerant circuit (20), an air conditioner unit (12), a refrigerating showcase (13), and a freezing showcase (14) are parallelly connected to an outdoor unit (11). To set an indoor heat exchanger (71) of the air conditioner unit (12) to a thermo-off state, opening degree control means (101) totally closes an indoor expansion valve (72). After that, the opening degree control means (101) detects the amount of refrigerant staying in the indoor heat exchanger (71) and adjusts the degree of opening of the indoor expansion valve (72) according to the amount of refrigerant.</p> |
