Classification: CPC F | IPC F

Claim 7:
8. A cooling apparatus comprising:
a first fluid flowpath including the following elements, in downstream flow sequence:
a subcooler having a first side in fluid communication with the first fluid flowpath and a second side configured to be disposed in thermal communication with a cold sink;
a flow control valve;
a primary evaporator assembly including at least one primary evaporator configured to be disposed in thermal communication with a primary heat load;
a pressure regulator operable to maintain a refrigerant saturation pressure within the primary evaporator at a predetermined set point;
a second fluid flowpath is configured to extract refrigerant from the first flowpath, pass the refrigerant through the second side of the subcooler, and return the refrigerant to the first fluid flowpath; and
a suction accumulator, wherein the second fluid flowpath and the first fluid flowpath both flow into the suction accumulator,
wherein the first fluid flowpath further comprises one or more secondary evaporators downstream of the primary evaporator assembly, configured to be disposed in thermal communication with a secondary heat load, wherein the primary evaporator assembly and the secondary evaporators are positioned in series.
