Emerson Climate Technologies updates Copeland compressor platforms for walk-in, reach-in refrigeration units

Emerson Climate Technologies has pursued major technology extensions to existing Copeland compressor and condensing unit platforms used in refrigeration systems servicing walk-in and reach-in applications in order to meet recent energy reduction standards mandated by the U.S. Department of Energy (DOE). By 2017, the DOE is requiring between a 30 to 40 percent improvement in both reach-in and walk-in energy efficiency. To meet these requirements, one of many Emerson initiatives has been an expansion of its Copeland Scroll™ line to include smaller displacements and capacities that are applicable for walk-in applications, capitalizing on the known efficiency benefits in this area. Other developments currently underway to meet the DOE energy reduction standards include generational improvements. For medium-temperature, walk-in applications, Emerson has extended the Copeland Scroll ZB*KA platform by reducing the horsepower (HP) range to ¾ HP, which may also be suitable for large reach-in units. For low-temperature, liquid injected scroll compressors, the horsepower has been reduced to a range of ¾ to 1 ½ HP to accommodate walk-in use. Additional efforts include a reduction in existing fractional horsepower compressors to less than ½ HP used in reach-ins and the development of new condensing units for the next generation of fractional horsepower compressors. Emerson is also currently developing higher-efficiency reciprocating compressors and condensing units for reach-in and other styles of self-contained applications. These condensing units will be harnessing new and more efficient fractional horsepower compressors. The condensing units include many design improvements to create two times the energy efficiency while maintaining the same small or potentially even smaller footprint.
