This training provides a background review of international treaties and initiatives that support the transition from hydrochlorofluorocarbon (HCFC) and hydrofluorocarbon (HFC) refrigerants towards non-ozone-depleting (ODP), low-global-warming-potential (GWP) substances. A review of proposed refrigerants and how they can be used in different HVAC&R applications based on theoretical and empirical analyses is discussed. Challenges and opportunities associated with the different types of refrigerants: hydrofluoroolefins and natural refrigerants are presented. Relevant refrigerant options for high ambient temperature (HAT) environments, and standards, codes of systems and substances are also covered. Finally, the course wraps up with a discussion on the systems perspective and how to best understand the opportunities for energy-efficiency improvements. This would include an introduction to free modeling tools such as the online ORNL Heat Pump Design Model.
