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.
