ABSTRACT:
A portable refrigeration machine includes a vertically oriented pressure vessel containing carbon dioxide in gaseous, liquid and/or solid states. A heat exchanger is secured to the lower external portion of the vessel and an outer housing surrounds the vessel to leave an annulus between the exterior wall of the vessel and the interior wall of the housing. A gas pressure operated fan is disposed beneath the heat exchanger and connected for operation by gas pressure from the vessel to rotate. The fan draws in air through appropriate lower inlet openings which air passes through the heat exchanger and annulus out outlet opening to thereby cool and circulate the air in a compartment within which the portable refrigeration machine is placed.
