Guidelines for selecting alternative refrigerants

Abstract

Abstract

Since the hydrochlorofluorocarbons (HCFCs) that are widely used in the vapour compression system for refrigeration and air conditioning can deplete the Ozone, a schedule to phase-out these refrigerants are starting from 2013 for the developing countries (including Thailand). To select alternative refrigerants properly, ones should know guidelines for refrigerant considerations. The aim of this paper is to synthesize available publications and experiences on refrigerant selections. The paper consists of systems for refrigerant consideration, available refrigerants and possible problems in drop-in replacement.
