| Abstract |
The purpose of this study is a comparative study the indoor thermal comfort and air quality analysis and energy consumption according to specific application type of economizer. Our country is becoming increasingly interested in energy saving in building. Economizer is one of energy conservation measures in HVAC system. This research analyzed dry-bulb control and enthalpy control economizer. The economizer control method satisfies all the conditions of indoor thermal comfort, indoor air quality. An enthalpy control economizer showed lower energy consumption than that of dry-bulb control economizer during simulated period. |
