Since the reintroduction of CO2 as a refrigerant in the mid-1990s, there have been significant efforts in the development of transcritical CO2 cycles to make their performance more competitive to that of HFC cycles. As a consequence, systems using CO2 continue to gain in popularity, particularly in commercial and industrial refrigeration markets. This seminar discusses how exploring new system variations and compressor technology are paving the way for further expansion of the CO2 transcritical market.
