A 1.5 ton window air conditioner was extensively instrumented and tested over a widerange of wet- and dry-coil operating conditions. The results were used to improve a steady-statesimulation model. Published air- and refrigerant-side heat transfer correlations were found tocharacterize wavy-fin evaporator and louvered-fin condenser performance quite well. Condensateremoval was predicted reasonably well, and 55% of its latent heat was recovered by spraying ontothe condenser. Evaporator and condenser face velocity nonuniformities found to range over afactor of three. A second set of tests conducted in a wind tunnel, using an identical evaporator,showed that the heat transfer and air-side pressure drop penalties due to these nonuniformities werequite small.
