BRA Guide to flammable refrigerants.

This guide has been prepared by the British Refrigeration Association (BRA) because of the increase in the application of flammable refrigerants such as hydrocarbons, HFOs and flammable HFCs. It provides impartial information about the flammability issues associated with these refrigerants to end users, specifiers, building owners, manufacturers and contractors. It is an introduction to flammable refrigerants and signposts where more detailed information can be obtained if necessary. It applies to the use of flammable refrigerants in new, specially designed systems. Existing systems using non-flammable refrigerants must not be retrofitted to flammable refrigerants. Extract from the table of contents: regulations, standard and codes of practice; transport of flammable gases in cylinders and equipment; maximum flammable gas charge size; comfort and non-comfort cooling/heating applications; systems/applications; overview of design; manufacture and of service; training.
