Comparison of global warming impacts of automobile air-conditioning concepts.

Author(s) : FISHER S. K.

Summary

The global warming impacts of conventional vapour compression automobile air conditioning using R134a are compared with the potential impacts of four alternative concepts. Comparisons are made on the basis of total equivalent warming impact (TEWI). Under the most favourable assumptions on efficiency and weight, transcritical compression using CO2 as the refrigerant and adsorption cooling with water and zeolite beds could reduce TEWI by up to 18% relative to R134a compression air conditioning. Neither Stirling cycle or thermoelectric cooling will reduce TEWI relative to R134a. Brief comments are also made concerning technical barriers that must be overcome for successful development of the new technologies.
