Air cooled centrifugal refrigeration system with water heat recovery
A refrigeration system is disclosed which includes evaporator means of the type for producing chilled liquid and wherein a compressor of the centrifugal type is provided for compressing refrigerant which has been vaporized in the evaporator means. Both air cooled and liquid cooled condenser means are connected in parallel flow relationship to the compressor, whereby the heat of condensation and compression may be rejected either to a source of ambient air or recovered through heat exchange with a source of liquid, whereby a heated liquid is produced for use as desired. Conduit means which are provided for passing condensed refrigerant from the air cooled and liquid cooled condenser means to the evaporator means include valve means for selectively varying the flow of condensed refrigerant from each. The flow of condensed refrigerant from the air cooled condenser means may be reduced so as to cause at least partial flooding thereof and thereby reduce its capacity, while the flow of condensed refrigerant from said liquid cooled condenser means may be increased so as to increase the production of heated liquid. Control means are also disclosed for operating the aforesaid valve means in response to a sensed demand for heated liquid.
