ABSTRACT:
Refrigeration apparatus and method generally include a compressor for compressing refrigerant gas to a liquid, an evaporator for evaporating refrigerant liquid to refrigerant gas and cooling in atmosphere adjacent the evaporator and a condenser for rejecting the heat of compression of hot refrigerant vapor to the atmosphere adjacent to the condenser. First and second chambers are provided separated by free-floating piston for alternately condensing refrigerant gas in the first chamber and storing refrigerant livid in the second chamber, and condensing refrigerant gas in the second chamber and storing refrigerant livid in the first chamber. Lines interconnecting the compressor, evaporator, condenser and the first and second chambers of the gas piston cylinder enable the compressor to alternately introduce refrigerant gas into the first chamber and move refrigerant livid into the evaporative means by displacement of the free-floating piston and introduce refrigerant gas into the second chamber and move refrigerant liquid into the evaporator by first displacement of the free-floating piston.
