Abstract
A thermal management system includes an integrated open-circuit refrigeration system and closed-circuit heat pump system. The thermal management system includes a receiver having a first receiver port and a second receiver port, the receiver configured to store a refrigerant fluid, an evaporator having a first evaporator port and a second evaporator port, the heat pump circuit having a closed-circuit fluid path with the receiver and the evaporator and an open-circuit refrigeration system configured to receive refrigerant from the receiver, with the open-circuit refrigeration system having an open-circuit fluid path that includes the receiver and the evaporator.
Claims68
A thermal management system comprising:
- a receiver that comprises a first receiver port and a second receiver port and is configured to store a refrigerant fluid;
- a first ejector comprising a primary inlet, a secondary inlet and an outlet;
- a second ejector comprising a primary inlet, a secondary inlet, and an outlet;
- an evaporator comprising a first evaporator port and a second evaporator port;
- a condenser device comprising a condenser inlet and a condenser outlet;
- a compressor comprising a compressor inlet and a compressor outlet;
- a heat pump circuit comprising the receiver, the ejector, the evaporator, the condenser, and the compressor fluidly coupled within a closed-circuit fluid path that further includes the second ejector;
- and
- an open-circuit refrigeration system configured to receive the refrigerant fluid from the receiver, with the open-circuit refrigeration system comprising the receiver, the ejector, the condenser, the compressor, and the evaporator fluidly coupled within an open-circuit fluid path.
