| Abstract | The purpose of this study was to analyze energy consumption using domestic and foreign ventilation standards which are applied to operation methods of variable air volume system in existing school building. The operation methods of variable air volume system are demand controlled ventilation system(DCV) and economizer system. It was found that domestic standard uses more cooling energy than ASHRAE standard in DCV. This is because domestic standard introduces more return air and the return air enthalpy is warmer than outdoor air enthalpy in semester. It was also found that cooling energy consumption in economizer is same in two standards. This is because when the outdoor air condition and the set point of supply and room air are constant in two standards, the outdoor air introduction rate is also same. Consequently, the domestic ventilation standard is expected to have an improvement in terms of energy consumption and indoor air quality. |
