Abstract
A heat pump for heating a vehicle interior includes a compressor arranged in a heat-pump circuit of a working medium, a condenser, a throttle valve and an evaporator. Gaseous working medium is compressed in the compressor. The compressor outlet is connected to the inlet of the condenser in which the working medium condenses, at the same time discharging heat, the heat being delivered as useful heat directly or indirectly to a consumer. The condenser is followed by a jet pump, to which the liquid working medium coming from the condenser is delivered as driving medium and to which the gaseous working medium flowing out from the evaporator is delivered as suction medium, in such a way that the driving medium and suction medium are compressed in the jet pump as a two-phase mixture. The jet-pump outlet is connected to the inlet of a separator, to which the two-phase mixture is delivered and in which the gaseous working medium is separated from the liquid working medium. The gas outlet of the separator is connected to the compressor inlet and the liquid outlet of the separator is connected to the inlet of the throttle valve, the liquid working medium being throttled in the throttle valve, and the outlet of the throttle valve is connected to the inlet of the evaporator, in which, by the supply of heat, phase transformation takes place to the gaseous working medium.
