Summary

A large percentage of compressor failures in low-temperature vapor-compression refrigeration system applications originate from overheating.
One cost-effective method of preventing destructive superheat at the compressor for HCFC-22 medium- and low-temperature systems was the introduction of the temperature responsive expansion valve (TREV). Using liquid from the high side of the system, the TREV injects saturated refrigerant into the suction line ahead of the compressor in direct response to the temperature of the discharge line.
