摘要： Refrigeration systems are described. The systems include a compression device, a heat rejecting heat exchanger, an ejector, and first and second expansion devices with respective heat absorbing heat exchangers. The ejector is arranged to receive refrigerant fluid from the heat rejecting heat exchanger at a high pressure inlet of the ejector. Fluid pathways extend from an outlet of the ejector into a branched flow path to provide flows of refrigerant from the ejector to the first and second expansion devices. The first heat absorbing heat exchanger provides cooling at a first temperature and refrigerant fluid from the outlet of the first heat absorbing heat exchanger is directed to a low pressure inlet of the ejector. The second heat absorbing heat exchanger provides cooling at a second temperature and refrigerant fluid from the outlet of the second heat absorbing heat exchanger is directed to the inlet of the compression device.

摘要： When intended to increase a refrigerant discharge capacity of a compressor in an ejector refrigeration cycle device at start-up of the compressor, the refrigerant discharge capacity is increased in such a manner that an increase amount in the refrigerant discharge capacity of the compressor per predetermined time period is lower than a maximum capacity increase amount per predetermined time period enabled by the compressor. Thus, even if a gas-liquid two-phase refrigerant flows into a refrigerant inflow passage forming a swirling-flow generating portion, the flow velocity of the gas-liquid two-phase refrigerant is prevented from becoming high, so that it can reduce friction noise that would be caused when the gas-liquid two-phase refrigerant circulates through the refrigerant inflow passage, further suppressing the generation of noise from the ejector.

摘要： 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.
