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. Single or dual phase cyclonic separators may also be housed in the plenum of the evaporative condenser.

摘要： A packaged, pumped liquid, recirculating refrigeration system with charges of 10 lbs or less of refrigerant per ton of refrigeration capacity. The compressor and related components are situated in a pre-packaged modular machine room, and in which the condenser is mounted on the machine room and the evaporator is close coupled to the pre-packaged modular machine room. Prior art large receiver vessels may be replaced with a single or dual phase cyclonic separator also housed in the pre-packaged modular machine room.

摘要： A tube bundle for an evaporative refrigerant condenser having a plurality of straight single pass tubes extending between a refrigerant inlet header and a refrigerant outlet header, said tubes having a cross-sectional shape in the form of an ellipse having a major axis and a minor axis, wherein said major axis is longer than said minor axis by a factor of 3 to 7, wherein the amount of required refrigerant charge for a particular heat exchange capacity is substantially and unexpectedly reduced resulting in a substantial and unexpected increase in efficiency.
