Document Type and Number:
WIPO Patent Application WO/2018/124788
Kind Code:
A1
Abstract:
The present invention relates to a heat pump for an automobile and, more specifically, the present invention is an invention relating to a heat pump for an automobile, which comprises a first direction-changing valve, a second direction-changing valve and a dehumidification line and performs air conditioning/heating/defrosting/dehumidifying operations according to the flow of a refrigerant. An embodiment provides a heat pump for an automobile, which comprises: a compressor for compressing and discharging a refrigerant; an inner heat exchanger allowing a heat exchange between the refrigerant and air in the interior of a vehicle; an outer heat exchanger allowing a heat exchange between the refrigerant and outside air; a first direction-changing valve supplying, to the inner heat exchanger, the refrigerant discharged from the compressor, or supplying same toward the outer heat exchanger without going through the inner heat exchanger, according to a heating, ventilation and air conditioning mode of the vehicle; a first expansion means disposed on the part of a refrigerant line between the inner heat exchanger and the outer heat exchanger, and provided to allow the refrigerant to expand; a second expansion means disposed on the refrigerant line, and provided to allow the refrigerant which has passed through the outer heat exchanger to expand; an evaporator provided at the rear end of the second expansion means; an accumulator for introducing the gas-phase refrigerant, of liquid-phase and gas-phase refrigerants in the refrigerant line, into the compressor; a third heat exchanger provided to exchange heat with a waste heat collection part, in the part of the refrigerant line formed to allow the refrigerant to flow into the accumulator without passing through the evaporator; and a second direction-changing valve supplying, to the second expansion means, the refrigerant which has passed through the outer heat exchanger, or supplying same toward the third heat exchanger without going through the second expansion means.
