The main objective of this guide is to provide information on aspects of design and installation standards that prevent or reduce refrigerant leakage. In order to reduce carbon dioxide emissions, it is vital that the initial design of the refrigeration system gives priority to eliminating potential cause of leaks. Getting the design right in the first place will reduce both direct and indirect emissions aspects of these emissions and will prevent problems in the long run.
This document has been produced specifically as an aid to consultants, designers and specifiers. End users may also find it a useful addition to their design specifications.
