Title:
VEHICLE HEAT PUMP SYSTEM
Document Type and Number:
WIPO Patent Application WO/2024/019339
Kind Code:
A1
Abstract:
Disclosed is a vehicle heat pump system which can implement various air-conditioning modes while minimizing the number of expansion valves, and which can comprise relatively low-priced components such that manufacturing costs can be significantly reduced. The vehicle heat pump system comprises: a compressor for discharging a refrigerant; an indoor heat exchanger which is provided in an air-conditioning case, and which allows heat exchange between air and the refrigerant discharged from the compressor so as to heat an indoor space; a water-cooled condenser which is provided downstream of the indoor heat exchanger in the flow direction of the refrigerant, and which exchanges heat with first cooling water; an outdoor heat exchanger which is provided downstream of the water-cooled condenser in the flow direction of the refrigerant, and which allows heat exchange between the refrigerant and outdoor air; an evaporator which is provided in the air-conditioning case, and which allows heat exchange between the refrigerant and the air so as to cool the indoor space; and a chiller, which is provided downstream of the outdoor heat exchanger in the flow direction of the refrigerant, is provided at a refrigerant line that bypasses the evaporator, and exchanges heat with second cooling water. The present invention includes an outdoor unit bypass line allowing the refrigerant having passed through the water-cooled condenser to bypass the outdoor heat exchanger, wherein the outdoor unit bypass line branches off between the water-cooled condenser and the outdoor heat exchanger and is connected to the upstream side of the chiller in the flow direction of the refrigerant.
