A Study on Indoor Temperature and Cooling Load in Night-Ventilated Building

Abstract:

The paper presents a qualitative effect of ventilation mode at daytime, night ventilation flow and outdoor air temperature, the temperature differences between of indoor air setting and outdoor air on cooling load reduction and indoor air temperature fluctuation at nighttime using thermal mass and night ventilation. A simple residential building model is chosen to obtain the hourly variation of cooling load at daytime and indoor air temperature at nighttime. It is noted that the temperature distribution of thermal mass material governed by an one-dimensional non-steady heat conduction equation .is considered in the paper. The dependence of the cooling load and indoor air temperature at nighttime on night ventilation flow, the outdoor air temperature, the temperature differences between of indoor air setting and outdoor air is further validated. Our results show that only suitable night ventilation flow with suitable outdoor climates and the appropriate temperature differences between of indoor air setting and outdoor air will benefit most. The present work provides guidance for designing night ventilation.
