Assessment of Life Cycle Climate Performance (LCCP) for chillers.

Author(s) : PEARSON A. B.

Summary

The use of LCCP assessment is becoming a preferred alternative to the Total Equivalent Warming Impact (TEWI) calculation because it includes consideration of the equivalent warming impact of the refrigerant during production as well as during use. However some recent studies using LCCP methods have concluded that fluorocarbon-based chillers are more environmentally friendly than those which use natural refrigerants. This conclusion is examined in detail in this paper, and LCCP calculations are detailed for existing water-cooled chillers using R717 and R134a, existing air-cooled chillers using R717 and R134a and a promising alternative system using R744.
