Abstract
An air conditioning apparatus includes a heat source unit, usage units, and a controller. The heat source unit has a compression mechanism, a heat-source-side heat exchanger operable at least as an evaporator, and a heat-source-side expansion valve. The usage units have usage-side heat exchangers operable at least as condensers, and usage-side expansion valves. The controller regulates the opening degree of the heat-source-side expansion valve based on the opening degrees of the usage-side expansion valves.
