Hydrocarbon Refrigerants 3rd Edition

Hydrocarbon (HC) refrigerants were approved for use by the US EPA through their SNAP program in early 2012, for specific refrigeration applications. This training was developed to assist the refrigeration technician in understanding the requirements of safely maintaining and servicing systems that utilize those flammable refrigerants currently approved under the EPA s SNAP program. This guide provides you with the knowledge you need to work safely with flammable refrigerants, including:EPA Regulations, UL Standards, Safety Issues, Refrigerant Properties, Service Procedures and much, much more! It is highly recommended that only experienced refrigeration professionals handle HCs. You should already have a solid understanding of the refrigeration cycle and proper handling of CFC, HCFC and HFC refrigerants. There are additional flammable refrigerants that may be approved in the future (e.g., R-1234yf). This training document will be updated (and additional testing and certificates will be required) as new refrigerants are approved.
