At the 20th European Conference on Refrigeration and Air Conditioning in Milan, Italy, Copeland presented innovative technology and complete compressor solutions that enable exceptionally quiet operation. With the help of the new Copeland YHV*RG and YHV*RT scroll compressors, original equipment manufacturers can develop efficient heat pumps that meet the particularly high requirements for low noise in the residential sector, but without the need for elaborate sound insulation.
The core of Copeland’s complete solution is a new type of variable speed scroll compressor designed specifically for heat pumps with R290 (propane) or R454C refrigerant. These scroll compressors generate a lower sound pressure than other scroll compressors: Compared to a standard Copeland compressor, the newly developed scroll compressors of the YHV low-sound series operate at full power with a 10 dB(A) lower sound pressure.
The low sound scroll compressors are complemented by the highly efficient Copeland EV3 drive and the advanced superheat envelope controller (SEC). They continuously monitor performance and ensure that all operating parameters are within their defined safety margins. Because the Copeland low-sound solution package combines quietness with the highest energy efficiency (A+++) and refrigerants with low global warming potential, it also ensures compliance with the F-Gas regulation, thus making it a future-proof investment.
“The Copeland package with scroll compressors, perfectly matched components and advanced control technology allows for the design of very quiet and compact heat pumps,” explains Enrico Fraccari, director marketing residential comfort, Europe for Copeland. “For manufacturers, this also combines great potential savings in material and labour costs – lower system costs in turn improve their competitiveness.”
