Papadopoulos, A J; Berger, S A

A production-possibilities curve for room air conditioners in the 8000-Btu/h-capacity range was constructed by upgrading a unit from an energy-efficiency ratio (EER) of 6.3 to 9.8 Btu/Wh through energy-saving improvements in heat exchangers, compressor, and fan. An energy-consumption and price-estimation model was developed. An initial increase of 30 percent in EER is possible using four-pole compressor and permanent-split-capacitor fan motors at an 8 percent price increase. Increasing condenser frontal area by 40 percent, doubling the number of coil rows, and replacing cooling fins with spines decrease energy consumption by 35 percent with a 40 percent increase in price.
