Dec. 03, 2007 – The overall effi ciency of a heat pump system is highly dependent on the performance of the compressor. Compressors in heat pumps not only encounter a wider range of operating conditions than in traditional air conditioners, but also have two to three times longer run times per year than compressors for air conditioners.
The combination of higher pressure ratios and extended operating times present specifi c challenges for compressor manufacturers. The proposed solutions to these challenges are the subject of this article.
