Refrigerants used in residential and commercial air-conditioning systems is the subject of a white paper from Emerson Climate Technologies Inc., provider of heating, air-conditioning, and refrigeration solutions for residential, industrial, and commercial applications.

The white paper, “Refrigerants for Residential and Commercial Air Conditioning Applications,” reviews environmental drivers, discusses regulations and timing, examines refrigerant choices, and looks at the future direction of refrigerants for air-conditioning systems. Issues discussed include the global-warming potential of refrigerants and the indirect global-warming issues of efficiency and power usage.

The white paper touches on the Air-Conditioning, Heating, and Refrigeration Institute’s new Alternative Refrigerants Evaluation Program and discusses total equivalent warming impact and life-cycle climate performance.
