The properties of the new low-GWP and natural refrigerants, such as HFO, R-32, R-152a, ammonia, hydrocarbons, CO2, etc. have an impact on the performance and efficiency of the refrigeration and air-conditioning systems and their components. A special attention in this session is dedicated to the design, operation, and servicing equipment with flammable refrigerants, such as hydrocarbons and ammonia. The issues and challenges are illustrated in the example of a household refrigerator/freezer with R600a for use on the U.S. market. Two presentations provide a comprehensive analysis of efficiency and operational aspects of equipment with ammonia.
