Summary

The author reports the steps taken by a supermarket chain, but the paper is valid for all similar users of refrigeration. Although the change from R502 to R22 or R69L is advocated, the main advice covers the introduction of R134a which this company is using in all systems evaporating at -12 deg C and above. First steps are to control the use of existing refrigerants with emphasis on reclaiming and recycling, also leak detection and leak-free maintenance. Advice on changing to R134a emphasises the removal of mineral oil. The recommended 1% level is seldom obtained because of long pipelines and heat exchanger tubes with enhanced internal surface. When designing new systems minimum refrigerant charge is an important criteria and leak detection equipment should be installed. For low temperature systems R22 is the obvious short term choice, but all users should be ready to adopt substitutes if and when they become available. D.W.H.
