摘要：

Substitutes for the commonly used refrigerants CFC-12 and CFC-502 are not commercially available. HCFC-22 is not suitable for low temperature applications because of the high discharge temperature caused by high compression ratios. Staged compression and liquid injection are two approaches to prevent compressor overheating in HCFC-22 low temperature applications. This paper describes the above approaches and their efficiency as compared to conventional applications.
