A heat pump system for climate control of an electric or hybrid vehicle includes an air conditioning unit having a heating heat exchanger, and an air conditioning unit evaporator having a refrigeration circuit, in which the air conditioning unit evaporator and a condenser are arranged. The refrigeration circuit includes a low temperature (LT) circuit in which at least one electrical power component is arranged. The heat pump system is configured to switch over between a cooling mode and a heating mode. The condenser, which is configured to transfer heat into the LT circuit, and an LT cooler are incorporated into the LT circuit. In the heating mode, the condenser outputs heat into the LT circuit and from there into a heating circuit, in which the heating heat exchanger is arranged, and in the cooling mode, the condenser outputs heat via the LT circuit to the LT cooler.
