The global warming impact of refrigeration, air-conditioning and heat pump (RAC&HP) technologies became the next urgent concern after addressing stratospheric ozone depletion from the chlorine-containing refrigerants. In addition to the direct impact of the leaked refrigerant, RAC&HP technologies contribute to global warming indirectly through the energy required for their operation. This seminar presents the most recent achievements in research and development of Low Global Warming Impact Technologies providing a balanced approach through the use of natural and low GWP refrigerants as well as through cycle, system and component design optimization for refrigerant charge reduction, leak elimination, and efficiency enhancements.
