ABSTRACT:
A refrigeration system which has a heat exchanger wherein refrigerant is evaporated to absorb heat from a fluid to be cooled, said heat exchanger receiving refrigerant from a vapor condensing economizer. The vapor condensing economizer receives liquid refrigerant from a condenser and has an orifice or a series of nozzles to maintain a pressure drop between the condenser and economizer so that a portion of the liquid refrigerant flashes to a vapor in the economizer to absorb heat from the remaining liquid refrigerant in the economizer. Condensing coils containing a cool heat exchange medium are positioned in the economizer to reduce the temperature and pressure in the economizer and to condense the refrigerant vapors back to a liquid for use in the refrigeration cycle.
