Industry Steps Up Efforts To Put CO<sub>2</sub> Refrigerant Into Use
If HFC refrigerants were ever to come under fire in the United States, the mobile and stationary HVACR sectors appear more and more ready to offer CO2. as an alternative. Four representatives of industry manufacturers and an enduser from the U.S. Army talked about work they are doing with CO2 to an audience of engineers at the combined Compressor Engineering Conference and Refrigeration & Air Conditioning Conference at Purdue University.
Their efforts are being driven by pending legislation in Europe that may end up banning the use of HFCs in automotive air conditioning; by environmentally and politically driven efforts among such high-profile end-users as Coca-Cola and McDonalds to end the use of HFCs in stationary equipment; and by research that is showing cost and energy efficiencies of CO2 systems starting to fall in line with similar equipment running on HFCs.
