VAPOR INJECTION MODULE AND VEHICLE HEAT MANAGEMENT DEVICE INCLUDING SAME

Abstract: a vehicle heat management device comprising a compressor compressing and circulating a refrigerant; a first heat exchanger into which the compressed refrigerant flows and exchanges heat with another heat exchange medium; a second heat exchanger exchanging heat with air outside a vehicle interior; a third heat exchanger that is installed in an air conditioner and exchanges heat with air discharged into the vehicle interior; and a vapor injection module that can make a gaseous refrigerant flow into the compressor. the vapor injection module includes a plurality of expansion means and a gas-liquid separator. in a cooling mode, refrigerant that has passed through the second heat exchanger flows into the vapor injection module. in a heating mode, refrigerant that has passed through the first heat exchanger flows into the vapor injection module. accordingly, the vehicle heat management device can be compact while having improved cooling and heating performance.
