METHOD AND DEVICE FOR GENERATION OF COLD Russian patent published in 1998 - IPC

FIELD: refrigerating engineering. SUBSTANCE: method is based on release of energy contained in substance by explosion process at combining different substances at different temperatures. Proposed method ensure release of cold at intensified of particles of substance. Device used for realization of this method delivers compressed or liquefied air or any other gas to interaction chamber of piston machine operating at required speed after 2-6 deg of turn of crankshaft and after passing top dead center; preheated water is injected into gas medium at reduced temperature at slightly excessive pressure. Explosion imparts pressure to piston and cold at negative temperature is released due to dissociation of water into oxygen and hydrogen; above-mentioned negative temperature is inversely equivalent to positive temperature at combustion of hydrogen in oxygen. Thus, generation of cold according to proposed method requires no energy, but is accompanied by release of energy of efficient work similarly to operation of internal combustion engine; besides that, waste gases may be used as fuel as mixture. EFFECT: enhanced efficiency. 2 dwg
