The purpose of this paper is to present the building energy consumption according to outdoor air intake methods which are the standard of CO2 concentration and the enthalpy difference between outdoor air and indoor air. For this, programs for predicting room air temperature based on the finite difference method were developed. Energy use simulation using systems of experimental design was performed to analyze the energy saving effect when a complex control method of CO2 concentration and enthalpy difference was applied as a method of outdoor air intake. The results show that a complex control method reduces the cooling energy use by an average of 1.4～19.5% in CO2 concentration of 800ppm, 3.3～20.4% in 900ppm, 4.5～21.0% in 1,000ppm. |
