Abstract

When bring outdoor air into buildings, energy consumption for heating and cooling generally increases. One of energy conservation measures, an economizer system can be used for energy conservation in buildings by allowing outdoor air for cooling. For the present study, the operation data of the AHUs were utilized and the optimal outdoor air fractions for economizer control types in Spring, Summer and Fall in South Korea were calculated and analyzed. In addition, the cooling loads were calculated according to the outdoor air fraction to achieve energy conserving economizer control type. As a result, the use of proper outdoor air can save more than 20% of building cooling load compared to no economizer system.
