Emerson launches second-generation variable-speed compressor, motor-control drive

St Louis, Missouri: Emerson Climate Technologies has announced launching the second generation of its Copeland Scroll variable speed ZPV2 compressor and EV2 motor control drive for residential and light commercial applications. Copeland Scroll variable speed technology, added the announcement, was named Product of the Year at the 2014 AHR Expo.

The compressor, the announcement said, features intermediate discharge valves to boost efficiency, optimised scroll elements for variable-speed performance, positive-displacement oil pump for enhanced reliability in low-speed operation and brushless permanent magnet (BPM) motor technology for maximum efficiency.

Its other product, the motor control drive, the company said, includes the Integrated CoreSense technology for optimal compressor performance, with features, such as soft starting capability, controlled shutdown, scroll over temperature protection and high-pressure cut-out. In addition, the announcement said, the drive protects the compressor from operating outside of the design parameters and against electrical power variations.

The two products, claimed the company, can enable system manufacturers to achieve industry-leading 25+ Seasonal Energy Efficiency Ratio (SEER) and 13+ Heating Seasonal Performance Factor (HSPF).  Homeowners and small businesses have reportedly experienced annual energy savings of up to 40% with HVAC systems featuring Copeland Scroll variable-speed compressors, the company added.

Brandy Powell, Vice President, Variable Speed at Emerson Climate Technologies Air Conditioning Business, said that modulating technologies from a consumer’s point of view was becoming increasingly important to the industry. “Our second generation, variable speed ZPV2 compressors and EV2 drives, he added, “are optimised to increase efficiency across a range of conditions while maintaining the reliability that Copeland Scroll technology traditionally delivers.”
