The Copeland horizontal variable speed scroll compressor (1 to 4 HP) has been recognized as a finalist in the annual AHR Expo (International Air-Conditioning, Heating, Refrigerating Exposition) Innovation Awards. This competition honors the most inventive heating, ventilating, air conditioning and refrigeration (HVACR) products, systems and technologies. For original equipment manufacturers (OEMs) and end users of self-contained, reach-in coolers and freezers, display cases and walk-in coolers, the Copeland horizontal variable speed scroll compressor delivers an ideal combination of sustainability, reliability and design flexibility.
Balancing the sustainability equation
Today, smaller-format food retail market trends and environmental and energy regulations are driving the transition toward more distributed refrigeration architectures. As more operators deploy flexible self-contained display cases, they also seek lower-global warming potential (GWP) refrigerant options and energy-efficient equipment that supports their corporate sustainability objectives.
Meeting these evolving requirements can present significant design challenges for OEMs of self-contained systems. One of the leading strategies for achieving high energy efficiencies or ENERGY STAR® certification relies on the use of large-capacity condenser coils, which can reduce available merchandising space in a display case. As a result, OEMs often place compressors on the top of a case — thereby increasing its overall size, limiting its aesthetic appeal, and creating higher noise levels.
The low-profile Copeland horizontal variable speed scroll compressor solves these known design challenges while delivering significant sustainability, energy efficiency and performance improvements. Available in capacity ranges from 1 to 4 HP, this innovative variable speed compression solution is ideal for use in a wide variety of self-contained commercial refrigeration applications.
To help end users comply with refrigerant regulations and/or meet sustainability objectives, the Copeland horizontal variable speed scroll compressor is approved for use with the next generation of lower-GWP refrigerants, including A1 (R-448/49A) and A3 (R-290) which have already been approved, as well as A2Ls in the near future. The recent R-290 charge limit increases approved by Underwriters Laboratories’ (UL) UL 60335-2-89 standard should also set the stage for the use of larger-capacity, R-290 based, self-contained display cases.
In addition, the Copeland horizontal variable speed scroll compressor combines brushless permanent magnet (BPM) motors with our advanced Copeland variable frequency drives (VFDs), EVM series to help OEMs meet the energy efficiency standards set by the Department of Energy (DOE) — even achieving its ENERGY STAR certification.
Benefiting end users and OEMs
The Copeland horizontal variable speed scroll compressor enables larger capacities in a smaller footprint while delivering proven scroll benefits and the many advantages of variable capacity modulation, including:
- Increased energy efficiency
- Improved compressor reliability
- Precise load matching for higher refrigeration performance
- Lower noise levels
BPM motors and advanced Copeland VFDs combine to achieve the following performance enhancements:
- 15% energy reduction compared to an equivalent fixed-speed scroll, per Emerson lab simulations
- Increased equipment reliability through proactive motor failure prevention
- Decreased susceptibility to power issues
- Reduced start/stop events
- Seamless integration with supervisory control platforms, such as Emerson’s Lumity™ E3 supervisory control
This recent recognition by the AHR Innovation Awards is validation of our commitment to helping OEMs and end users address modern refrigeration challenges. The Copeland variable speed horizontal scroll compressor helps OEMs to meet low-profile equipment design challenges while allowing end users to adopt sustainable refrigeration strategies.
As refrigerant regulations evolve, refrigeration architectures will continue to leverage self-contained, distributed systems and utilize lower-GWP refrigerant alternatives. By integrating a Copeland horizontal variable speed scroll compressor in their self-contained, reach-in coolers and freezers, display cases and walk-ins, OEMs can significantly improve system energy efficiency and performance.
