Title:Effect of Airflow Nonuniformity of Room Air Conditioner Performance
Author(s):Kirby, E.S.; Bullard, C.W.; Dunn, W.E.
Subject(s):stationary air conditioning system analysis
Abstract:A 1.5 ton window air conditioner was extensively instrumented and tested over a wide range of wet- and dry-coil operating conditions. The results were used to improve a steady-state simulation model. Published air- and refrigerant-side heat transfer correlations were found to characterize wavy-fin evaporator and louvered-fin condenser performance quite well. Condensate removal was predicted reasonably well, and 55% of its latent heat was recovered by spraying onto the condenser. Evaporator and condenser face velocity nonuniformities found to range over a factor 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 were quite small.
