Title:
HEAT MANAGEMENT SYSTEM FOR VEHICLE
Document Type and Number:
WIPO Patent Application WO/2020/204570
Kind Code:
A1
Abstract:
The present invention relates to a heat management system for a vehicle. The purpose of the present invention is to control the flow of a refrigerant between low-pressure-side heat exchangers in a serial or parallel manner according to an air-conditioning mode state such that the flow rate of the refrigerant introduced into each low-pressure-side heat exchanger can be controlled independently according to the air-conditioning mode state, and to ensure that the refrigerant is introduced into each low-pressure-side heat exchanger at an optimal flow rate according to each amount of heat. In order to accomplish such a purpose, the present invention provides a vehicle heat management system having a heat pump-type refrigerant circulation line for producing hot or cold air according to the direction of flow of a refrigerant, thereby cooling/heating a specific air-conditioning region. The vehicle heat management system comprises: a compressor for suctioning, compressing, and discharging a refrigerant; a high-pressure-side heat exchanger for releasing heat from the refrigerant discharged by the compressor; an outdoor heat exchanger for causing heat exchange between the refrigerant and air outside a vehicle room; an expansion valve for pressure-reducing the refrigerant flowing out of the high-pressure-side heat exchanger or the outdoor heat exchanger; and at least one low-pressure-side heat exchanger for evaporating the pressure-reduced refrigerant. The outdoor heat exchanger and the low-pressure-side heat exchanger are connected in series or parallel according to the air-conditioning mode.
