취침 시 환기횟수에 따른 CO2 피크치 제어에 관한 연구

Ventilation requirement of apartment was mandated according to building equipment standards in 2006. When ventilation unit was considering for indoor air quality maintenance, we needed energy saving and efficiency ventilation control methods. This study carried out experiment of ventilation rate 0.7 adequacy. When we lived in apartment, we assumed that sleeping time was long stayed time in unconsciousness. Experiments carried out ventilation rate 0, 0.1, 0.4 and 0.7 in environment chamber from 22 o’clock to 06 o’clock, the concentration of CO2, temperature and humidity rate measured. Analyzing the results, conclusions are as follows. 1)When we sleep in bedroom, ventilation rate 0.4 meet the requirements of domestic legal standards. Conform fan of similarity law, ventilation rate 0.4 reduced power cost about 80% than 0.7. 2)In generally sleeping time 8 hours, peak point control reduced running time of ventilation unit about 43% than normal control.
