Abstract

A 2.5 ton, minimum-TEWI split system air conditioner prototype was tested over an extensive range of operating conditions to validate the system simulation model that had been used to design the prototype. The experimental results were compared with system and component-only simulations to quantify performance. The overall measured system capacity was 13% less than the model predicted at dry coil conditions and 18% less for wet coil conditions. Analysis of individual component identified flow maldistribution in both the microchannel condenser and evaporator coils. The model simulations combined with experimental data provided guidelines for improving flow distribution and component performance. Finally, the experimental results from the prototype confirmed initial design recommendations for a minimum-TEWI residential air conditioner. Additional constraints on the design recommendations were developed to ensure optimal performance for all components in the system.
