Energy use implications of methods to maintain heat exchanger coil cleanliness

The author's review of indoor particulate concentrations, air flows and filter effectiveness showed that considerable amounts of these particulates accumulate and build up between the fins of heat exchanger coils, typically used for unitary air conditioners, air-to-air heat pumps and condensing furnaces. Relating the particulate buildup to heat exchanger performance (i.e. actual capacity) provides a means to evaluate the associated energy use implications. By using high efficiency air cleaners, operating cost savings result from avoided coil cleaning costs and reduced energy consumption of the AC or heat pump to maintain equal comfort levels. These preliminary savings, which depend on climate, indoor air particulate concentration, fin spacing, relative coil capacity, fan operating time, filter/cleaner efficiency and maintenance practices, are reported here.
