A heat pump system (10) includes a fluid refrigerant compressor (12) and heat exchanger units (14, 16). Heat transfer tubings (36, 50, 58, 60, 66, 82) interconnect the fluid refrigerant compressor (12) and the heat exchanger units (14, 16) in a series relationship for carrying refrigerant fluid. Flo

A heat pump system (10) includes a fluid refrigerant compressor (12) and heat exchanger units (14, 16). Heat transfer tubings (36, 50, 58, 60, 66, 82) interconnect the fluid refrigerant compressor (12) and the heat exchanger units (14, 16) in a series relationship for carrying refrigerant fluid. Flow control valves (22, 24) are provided and are interconnected between a treated waste effluent source (20) such as a municipal or private treated waste effluent supply or reservoir and the heat exchanger unit (16) for controlling the amount of water flowing from the treated waste effluent source (20) to the heat exchanger unit (16). The flow control valves (22, 24) are responsive to the pressure at the outlet (12b) of the fluid refrigerant compressor (12) sensed at port (26) in the heat transfer tubing (58) to automatically optimize the operating condition of the heat pump system (10). To further optimize the heat pump system (10) in the heating mode, water from treated waste effluent source (20) flows through preheat exchanger (104) before entering heat exchanger unit (16).

The heat exchanger (16) directs cooled pressurized cryogen fluid to the solid cryogen reservoir (18) and Joule-Thomson orifice (42) and is positioned remotely from the cryogen reservoir (18). In an illustrative embodiment, the heat exchanger (16) outputs cooled cryogen gas to plural solid cryogen reservoirs (18) to cool plural corresponding infrared focal plane arrays (50). A line cutter selectively detaches the gas canister and/or the heat exchanger (16) from the missile in response control signal from a computer. The computer generates the control signal after a predetermined amount of the cryogen fluid is present in the cryogen reservoir (18) or after a predetermined time interval.
