Abstract

The study analyzed the effect of common installation faults on the cooling performance of a residential, split air conditioner installed in a single-family, slab-on-grade house. We considered five climatic regions in the United States from hot/humid to cold. Through annual simulations of the house/air conditioner system, the study found that air conditioner oversizing with non-oversized ductwork, duct leakage, refrigerant undercharge, undersized refrigerant expansion valve, and low indoor airflow have the most potential for causing significant performance degradation and increased annual energy consumption. A significant increase in annual energy use can be caused by lowering the thermostat setting to improve indoor comfort in cases of excessive indoor humidity levels due to installation faults.
