Type of article: Article

Summary

An energy analysis of screw compressors for low temperature evaporation. Four alternative systems are discussed: classical booster system, flash booster system, economizer system and two-stage compressor system. Diagrams are presented of coefficient of refrigeration capacity for R22 and ammonia installations. The most energy efficient is the classical booster system, but its investment costs are the highest. The economizer systems in R22 installations have very high coefficients; in ammonia plants, the coefficients are lower.
