Title:
AIR CONDITIONING DEVICE
Document Type and Number:
WIPO Patent Application WO/2022/181110
Kind Code:
A1
Abstract:
This air conditioning device comprises: a heat pump cycle (10, 10a) having a compressor (11), heating parts (12, 40, 121), and a low temperature-side water-refrigerant heat exchanger (20); a heating medium circuit (50, 50a); and a fan (32). The heating medium circuit (50, 50a) has a heat generating part (54) disposed therein. The air conditioning device executes heating preparation control in which, when using heat generated by the heat generating part (54) to improve the heating capacity of the heating parts (12, 40, 121), the refrigerant-discharging capacity of the compressor (11) is set to be at most a reference discharging capacity determined in advance and the air-blowing capacity of the fan (32) is set to be at most a reference air-blowing capacity determined in advance, until the inlet-side heating medium temperature (TWin) of the heating medium which flows into a heating medium path (20b) of the low temperature-side water-refrigerant heat exchanger (20) becomes at least a target heating medium temperature (TWinO).
