Abstract
A system is adapted to be vehicle mounted and powered by a D.C. source coupled with an inverter to cool individuals or temperature sensitive hardware under uncomfortable ambient conditions. The system includes a pumped liquid circulation loop which can be connected by self-sealing lines with cooling garments, temperature sensitive hardware and the like. An evaporative heat exchanger is provided in the loop as well as a liquid reservoir which is sized to limit short cycling of a compressor in a refrigeration loop associated therewith via the evaporative heat exchanger. A hot gas bypass can be associated with the compressor to allow recirculation of the superheated refrigerant gas when cooling is not required.
