Abstract:
A series of amendments to the international standards concerning refrigeration and A/C equipment is almost available to provide the additional safety measures required for the design, repair and service of refrigeration and A/C equipment using flammable refrigerants. These amendments will provide the framework to develop future refrigeration technology employing hydrocarbons. This paper reviews the different existing standards and the forthcoming drafts highlighting the maximum charge and room area limits as well as the specific requirements for air-conditioning and refrigerating equipment operating with hydrocarbons.
