| Abstract |
This paper presents the results of research into the problem of air filter management related with the air filter-associated fan energy consumption. Both energy performance data and air filter differential pressure of AHU in real commercial buildings were monitored and analyzed to investigate quantitatively energy impact as dust buildup level on air filter grows. An empirical equation was suggested through the regression analysis of multiple independent variables. An air filter differential pressure management model is also proposed and described as being an economical strategy in preventing high energy consumption. The system can create a useful alarm on a real time basis which would detect when an air filter needs to be changed and alert the building operator to do so, thereby minimizing the energy consumed by the air conditioning system. |
