Course Length: 6 hours
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, low-global-warming-potential 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 are presented, including hydrofluoroolefins and natural refrigerants. Current and future refrigerant options suiting the region are covered, as well as related standards and codes of systems and substances. Finally, the course wraps up with a discussion on the systems perspective and how to best understand the opportunities for energy-efficiency improvements along with hands-on experience with free software, such as life-cycle climate performance web applications and the heat pump design models.
