Author(s) : SNYDER D.

Type of article: Article

Summary

The author begins by explaining the result of low suction pressure in a vapour-compression refrigeration system. Examples of compression ratio and volumetric efficiency effects on compressor efficiency are given. Possible causes of low suction pressure are analysed, including bad system design, reduced air flow over evaporator, oil-logging, clogged filters, and expansion valve faults. D.W.H.
