Abstract
A heat pump system includes a compressor, a four-way valve, an outdoor heat exchanger, a throttling device and an indoor heat exchanger connected in sequence to form a refrigerant main circuit. The outdoor heat exchanger includes at least one double-rowed heat exchanger. The heat pump system has a cooling mode and a heating mode, and further includes a switching unit. The switching unit is connected in the refrigerant main circuit, and switches a flow direction of a refrigerant, such that the refrigerant flows into the outdoor heat exchanger through one of the first heat exchanger and the second heat exchanger, and flows out of the outdoor heat exchanger through the other one of the first heat exchanger and the second heat exchanger both in the cooling mode and in the heating mode.
