LOW CHARGE PACKAGED AMMONIA REFRIGERATION SYSTEM WITH EVAPORATIVE CONDENSER.

摘要

A packaged, pumped liquid, evaporative-condensing recirculating ammonia refrigeration system with charges of 10 lbs or less of refrigerant per ton of refrigeration capacity. The compressor and related components are situated inside the plenum of a standard evaporative condenser unit, and the evaporator is close coupled to the evaporative condenser. Prior art large receiver vessels may be replaced with a single or dual phase cyclonic separator also housed in the plenum of the evaporative condenser.
