ABSTRACT:
A snow gun and process for making artificial snow comprising a heat exchanger for holding air and water in separate, adjacent chambers and an ejector manifold that disperses air/water admixture to the ambient atmosphere. A multi-chambered heat exchanger is designed so that incoming water completely envelops the air jacket, thus warming the incoming air. Thereafter the water, generally under pressure, entrains the air through use of a multi-ported manifold, using air ejector phenomenon, and is exhausted to the atmosphere where the expelled air/water admixture dissociates to finely atomized water droplets, which subsequently freeze to form artificial snow.
