Title:
HEAT PUMP SYSTEM
Document Type and Number:
WIPO Patent Application WO/2010/024553
Kind Code:
A2
Abstract:
The present invention relates to a heat pump system, and more particularly, to a defrosting and cooling promoting structure of an outdoor heat exchanger in a heat pump system, which heats or cools the outdoor heat exchanger by using a costless heat source and the supercooled condensation heat of a refrigerant liquid to maintain an appropriate supercooling degree of the refrigerant liquid, and increase the performance reactor without using a fee-charging heat source. The heat pump system of the present invention includes: a base freezing circuit (10) in which a compressor (11), a four-way valve (12), an indoor heat exchanger (13), a cooling expansion valve (14), a heating expansion valve (15), an outdoor heat exchanger (16), and the four-way valve (12) are connected in a sequence via a refrigerant conduit (17), and the four-way valve (12) and the compressor (11) are connected via a refrigerant suction conduit (18); a heat accumulator (20) having a bypass refrigerant conduit (21) with both ends connected to the refrigerant conduit (17) between the cooling expansion valve (14) and the heating expansion valve (15), and a heat exchanger (22) for heating mounted on the bypass refrigerant conduit (21), wherein the heat exchanger (22) for heating is surrounded by the heat accumulator (20), and the heat accumulator (20) is injected with a heating medium (23); an auxiliary heat exchanger (30) connected to the heat accumulator (22) via a heating medium supply conduit (31) mounted with a heating medium circulation pump (32), and a heating medium return conduit (33), and installed in the outdoor heat exchanger (16); and an outdoor heat exchanger defrosting and cooling means (40) having a heat exchanger (41) connected to the heating medium supply conduit (31) and the heating medium return conduit (33) via a brine supply conduit (42) mounted with a brine circulation pump (43), and a brine return conduit (44), and having a costless heat reservoir (45) arranged around the heat exchanger (41).
