Abstract
A thermal management system is described. The thermal management system includes a receiver configured to store a refrigerant, the receiver having a receiver inlet and a receiver outlet, a closed-circuit refrigeration system including a vapor compression closed-circuit system that includes the receiver, and a closed-circuit system that includes the receiver, wherein the closed-circuit refrigeration system is configurable to receive refrigerant from the receiver through one or both of the vapor compression closed-circuit system and the closed-circuit system.
Claims51
A thermal management system, comprising:
- a receiver configured to store a refrigerant fluid, the receiver comprising a receiver inlet and a receiver outlet;
- a closed-circuit refrigeration system, comprising:
- a vapor compression closed-circuit system that includes the receiver and further comprises:
- a first evaporator and a second evaporator, each of the first and second evaporator comprising an inlet and an outlet;
- a liquid comprising an inlet, a liquid-side outlet, and a vapor-side outlet;
- and
- an ejector comprising a primary inlet configured to receive the refrigerant fluid from the receiver and an outlet configured to deliver the refrigerant fluid to the liquid separator from the outlet of the first evaporator;
- a closed-circuit system that includes the receiver and further comprises:
- a third evaporator comprising an inlet and an outlet;
- wherein the closed-circuit refrigeration system is configured to receive the refrigerant fluid from the receiver through at least one of the vapor compression closed-circuit system or the closed-circuit system;
- and
- an open-circuit refrigeration system comprising an open-circuit fluid path that extends from the receiver outlet to an exhaust line.

A thermal management method, comprising:
- transporting a refrigerant fluid from a receiver that stores the refrigerant fluid through a closed-circuit refrigeration system, with the closed-circuit refrigeration system comprising a vapor compression closed-circuit system that includes first and second evaporators, an ejector, a liquid separator, and the receiver;
- transporting the refrigerant fluid from the receiver through a closed-circuit system of the closed-circuit refrigeration system, the closed-circuit system including the receiver and a third evaporator;
- receiving the refrigerant fluid at the receiver through at least one of the vapor compression closed-circuit refrigeration system or the closed-circuit system;
- transporting the refrigerant fluid through the closed-circuit system to the third evaporator;
- and
- extracting heat from at least one heat load thermally coupled to the third evaporator.

- transporting the refrigerant fluid from the receiver through a closed-circuit system of the closed-circuit refrigeration system, the closed-circuit system including the receiver and a third evaporator;
- receiving the refrigerant fluid at the receiver through at least one of the vapor compression closed-circuit refrigeration system or the closed-circuit system;
- transporting a portion of a refrigerant vapor from the first and second evaporators into an inlet of the liquid separator that has a vapor-side outlet coupled to an inlet of a junction device;
- transporting the portion of the refrigerant vapor from the liquid separator to a back-pressure regulator having an inlet coupled to the vapor-side outlet of the liquid separator;
- and
- pumping, with at least one pump of the closed-circuit system, the refrigerant fluid from the receiver into the third evaporator.
