Title:
HEAT PUMP CYCLE
Document Type and Number:
WIPO Patent Application WO/2012/108211
Kind Code:
A1
Abstract:
A heat pump cycle applied to an air-conditioning device (1) capable of switching the operating mode between a cooling operating mode, a heating operating mode, and a dehumidifying-heating operating mode, wherein the heat pump cycle is constructed so as to be capable of setting both a high-stage-side decompression unit (13) and low-stage-side decompression units (16b, 17, 18) to a throttled state and to a fully open state. Thus, cooling, heating, and dehumidification heating can be implemented with a simple construction, without separately providing a cooling medium flow path from a compressor (11) to an outdoor heat exchanger (20) according to the operating mode of the air-conditioner.
