Over the last few decades, synthetic refrigerants such as CFCs and HCFCs are being phased out by regulation. Increasing concern and regulatory actions related to the environmental impact of HFCs has prompted a re-emergence of CO2 based refrigeration systems.
In recent years, coil technology has increasingly focused on microchannel. This advanced approach offers a way to improve thermal performance, reduce refrigerant charge, and improve corrosion resistance. The application of this technology originated in the auto industry more than 20 years ago.
