A heat pump system includes a compressor, a fluid switching device, a first heat exchanger, a second heat exchanger, a third heat exchanger, a fourth heat exchanger, a flow regulating device and a throttle element. The second heat exchanger includes a first heat exchange portion and a second heat exchange portion. An outlet of the first heat exchange portion communicates with the throttle element. An inlet of the first heat exchange portion communicates with at least one of a second port of the third heat exchanger and an outlet of the fourth heat exchanger. An inlet of the second heat exchange portion communicates with the outlet of the first heat exchanger. An outlet of the second heat exchange portion communicates with an inlet of the compressor. In a heating mode, the function of the second heat exchanger is reduced, thereby the heating capacity of the heat pump system is improved.
