REGENERATIVE AIR CONDITIONER

WIPO Patent Application WO/2016/103684

A1

A refrigerant circuit (11) having: a main heat-storage flow path (44) having a heat-storage unit (60) connected thereto; and an intermediate suction unit (35) that sucks an intermediate-pressure refrigerant into compression units (22, 80), said refrigerant being at an intermediate pressure between high pressure and low pressure for the refrigerant circuit (11). The refrigerant circuit (11) performs a first utilization heating operation that: causes some of the refrigerant condensed by an indoor heat exchanger (72) to branch towards the main heat-storage flow path (44), be evaporated by the heat-storage unit (60), and be sucked into the intermediate suction unit (35) for the compression units (22, 80); and, at the same time, causes the remainder of the refrigerant condensed by the indoor heat exchanger (72) to be evaporated by an external heat exchanger (23) and then be sucked into low-pressure suction units (28, 84) for the compression units (22, 80).
