Comparison of TEWI for fluorocarbon alternative refrigerants and technologies in residential heat pumps and air-conditioners.

Author(s) : SAND J. R., FISCHER S. K., BAXTER D. van

Summary

Alternative systems are compared with the TEWI of conventional R22 based vapour compression systems under the same operating conditions. TEWI results from previous reports, and those presented here show that the direct global warming potential (GWP) of the refrigerant used for residential heat pump applications contributes less than 7% to the total TEWI for these products and that the direct GWP of the refrigerant is less important than the overall efficiency of the unitary system (Fischer 1991; Fischer 1994; Sand et al. 1997). Clearly, any refrigerant or refrigerant blend proposed as an alternative for R22 must provide good cycle efficiency in addition to acceptable environmental and operational qualities to be seriously considered in unitary equipment applications.
