Vapor injection is a versatile method of improving system capacity and efficiency in many commercial refrigeration applications. Traditionally the only way to enjoy the added benefits of this type of mechanical subcooling was with a large screw compressor or two semi-hermetic reciprocating compressors. Now the Copeland Scroll® compressor enables significant performance gains with a single compressor. Injecting vapor in the middle of the compression process boosts capacities and efficiencies significantly. Scroll Compressors in Refrigeration Building on the success of scroll compressors in the refrigeration market world-wide, Emerson Climate Technologies, Inc. includes the ZF*KVE family of high efficiency refrigeration scrolls with vapor injection dedicated to low temperature applications. Vapor Injection Circuit for Low Temperature Applications The new scroll range includes 6 models from 4 to 15 HP and is designed to offer high efficiency levels at low evaporating temperatures with R404A and R507. It is the ideal choice for condensing units, parallel racks and distributed refrigeration systems. Copeland Scroll with Vapor Injection The ZF*KVE scroll compressor cycle is similar to a two-stage cycle with interstage cooling but with one single compressor. The high stage consists of extracting a portion of the condenser liquid and expanding it through an expansion valve into a heat exchanger acting as a subcooler. The superheated vapor is then injected into an intermediate port in the scroll compressor. The additional subcooling increases evaporator capacity.
