Abstract

There has been only limited research on light commercial packaged HVAC units. Optimization of unit function, through review of refrigerant charge, system airflow, and controls can offer substantial savings in certain climates. However, a systematic enhanced maintenance protocol has apparently not been used widely in this sector.

This paper reports on efforts in the Pacific Northwest to develop a procedure that can be used to evaluate the performance of rooftop packaged heating/cooling systems and discusses results from applying the protocol to 30 rooftop units. Estimates of savings potential (based on detailed simulations) are also presented.
