7. 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.

1,The advantages of scroll technology combined with the benefits of vapor injection: • Lower First Cost: increased cooling capacity leads to use of smaller or fewer compressors.

• Lower Operating Costs: efficiency gains enable ZF*KVE to outperform reciprocating compressors and reduce energy consumption significantly.

• Environmental Safeguards: improved efficiency allows for energy savings and reduced CO2 emissions.

• Compactness: weight and dimensions for refrigeration equipment is reduced with increased capacity per compressor.

• System Stability: the enhanced vapor injection effect is proportional to the pressure ratio, therefore the delivered capacity consistantly matches the seasonal load associated
