The R22 alternatives R32/125/152a and R290 and their mixtures have bee
n analyzed and evaluated in a room air conditioner. The cooling capaci
ties, energy efficiencies, compressor discharge temperatures, and pres
sures of alternatives have been compared with R22. R32/125/152a mixtur
es were found to be the most effective coolants. (C) 1997 Elsevier Sci
