This provides a really interesting overview of the technology and application of current refrigerants and although focussing on unitary equipment in the US it takes a broad minded approach and considers the international application and global impact of refrigeration. It is a lengthy video but is worth the time to gain insight into the history and evolution of 'new' and rediscovered refrigerants that aim to reduce the environmental impact of refrigeration in the building services (HVAC&R) industries for domestic and commercial applications.

The R454B units will be phased out in 5 years or sooner if they can make CO2 work above 87 F ambient temperatures.
