Our country has a very high Dependence of Energy on Overseas. And more than half of the building energy consumption is used in the building-Air Handling Unit. In addition, the development of construction technology and living standards demand the form of various buildings. So Resulting in an increase in the cooling loads, the energy consumption is increased. Reducing the loads using outdoor air is in the spotlight the way of energy saving. By using Economizer control the temperature and humidity automatically. Therefore it reduces unnecessary energy waste and make a comfortable environment. The purpose of this study is a comparative study the energy saving effects using a simulation program(Energy plus) for each type of Economizer.
