Commercial Refrigeration Applying R744 Refrigeration Technologies: A Global Perspective

Energy efficiency, heat recovery and cost efficiency of commercial refrigeration systems still have a large development potential for systems applying R744 as the only refrigerant. The system architecture has to be in the focus with respect to increase the system efficiency when these units are operated at elevated ambient temperatures. The objective of this work is to investigate the energy required for different R744 commercial refrigeration systems at various locations in all the global continents compared to a HFC404A configuration.
