Copeland has introduced its YAW and YAV variable-speed compressor platforms, designed to enhance heat pump performance in commercial and residential heating applications across cold climates down to -25 °F (approx. -32 °C). The launch supports manufacturers working to meet increasing demand for high-efficiency, low-carbon heating technologies.
The YAV platform extends heat pump capacity to maintain comfort in low ambient temperatures for both residential and commercial systems. It features modulation capabilities that allow compressors to match part-load requirements, reducing energy waste from frequent cycling. In colder conditions, the compressors can overspeed to increase heating output.
The YAW platform includes scroll design enhancements optimized for A2L low-global warming potential (GWP) refrigerants and features an injection port for an enhanced vapor injection (EVI) loop. This enables precise vapor injection during the compression cycle while subcooling refrigerant entering the evaporator. According to Copeland, this can improve heating capacity by up to 25% and heating efficiency by up to 10%.
Both platforms are intended to help OEMs comply with the U.S. Department of Energy’s Cold Climate Heat Pump (CCHP) standards. The CCHP program encourages manufacturers and researchers to develop next-generation heat pump solutions capable of operating efficiently in severe climates.
“Copeland is a global leader in helping the residential, commercial and industrial sectors advance heat pump adoption and drive the electrification of HVAC and water heating technologies,” said Mark Bills, vice president and general manager of commercial HVAC at Copeland. “Through partnerships with leading OEMs, grants from the DOE, and significant investments in research and development, Copeland is playing an integral role in the development of the next generation of heat pump technologies.”
