<p>An air conditioning device (10) is provided with a heat source unit (20), utilization units (40, 50, 60), and a control unit (80). The heat source unit (20) has a compression mechanism (21), a heat source-side heat exchanger (23) which serves at least as an evaporator, and a heat source-side expansion valve (38). The utilization units (40, 50, 60) have utilization-side heat exchangers (42, 52, 62) serving at least as condensers, and also have utilization-side expansion valves (41, 51, 61). The control unit (80) adjusts the extent of opening of the heat source-side expansion valve (38) on the basis of the extent of opening of the utilization-side expansion valves (41, 51, 61).</p> |
