Title: HEAT PUMP FOR AUTOMOBILE
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, comprising dual loops including a refrigerant loop and a cooling water loop, and performing air conditioning/heating/defrosting/dehumidifying operations by means of the dual loops being linked to each other. An embodiment of the present invention provides a heat pump for an automobile, which comprises dual loops by further comprising: a first fluid line through which a first fluid flows; a compressor for compressing and discharging the first fluid; an inner heat exchanger allowing a heat exchange between the first fluid and air in the interior of a vehicle; an outer heat exchanger allowing a heat exchange between the first fluid and outside air; a first expansion means disposed on the first fluid line between the inner heat exchanger and the outer heat exchanger, and provided to allow the first fluid to expand; a second expansion means disposed on the first fluid line, and provided to allow the first fluid, which has passed through the outer heat exchanger, to expand; an accumulator for introducing the gas-phase refrigerant, of liquid-phase and gas-phase refrigerants in the first fluid line which have passed through the second expansion means, into the compressor; a third heat exchanger disposed on the first fluid line between the second expansion means and the accumulator, and allowing a heat exchange with a second fluid; and a second fluid line connected to the third heat exchanger.
