The system uses a batch method process absorption cooling through a number of separate sealed two compartment containers which are moved physically between a heating area, a cooling area, a storage area and a refrigeration area. Pressure differentials alone between the two sections of a vessel power refrigerant movement and evaporation of refrigerant. A valve separates a refrigerant collector and evaporator section from an absorber/desorber section allowing the absorbent and refrigerant to be kept separate until needed. This system can be used with either ammonia water mixtures or with lithium bromide water mixtures.
