Abstract
A heat pump system includes a liquid receiver valve that adjusts the amount of a refrigerant stored in a liquid receiver so that a circulation amount of the refrigerant that circulates the heat pump system can be adjusted according to a driving speed of a compressor and performance of the compressor and the heat pump system can be further improved. Also, since a plurality of liquid receiver refrigerant outlets can be selectively opened using a pressure difference between an inlet and an outlet of the compressor, active control can be performed.
