Impact of air-filter condition on HVAC (heating, ventilation, and air conditioning) equipment

Technical Report ·
OSTI ID:5617082
An analysis was performed of changes in energy consumption caused by dirty filters for heating, ventilation, and airconditioning systems during both heating and cooling cycles. Basic heat-transfer fundamentals and the vapor-compression refrigeration cycle for air conditioners were used. The energy cost savings between a dirty and a clean filter were small and were mainly offset by the filter cost. However, the consequences of deferring filter replacement could be very costly because of early equipment failures. 19 refs., 5 figs., 6 tabs.
