摘要：
Changes in the final air status points caused by unreasonable window opening patterns can result in wasted energy from intermittently operating air conditioning systems. To grasp the influential characteristics of indoor air state point changes, the influence of weather conditions, window opening rate, and intermittent window opening time on indoor air state points were comparatively analyzed through experimental and simulation studies. The results show that there is no significant correlation between the final indoor air state point and weather conditions under the closed window condition. Under open window conditions, the size of the outdoor humidity determines the upper limit of indoor humidity at the final moment. It is not recommended to open windows on rainy days with high humidity, and it is more appropriate to open 1/6 of windows on sunny days with high temperature and low humidity. Different window opening ratios have little effect on the change of the final air state point, with indoor temperature fluctuating within 1 degrees C and humidity fluctuating within 0-5% RH. The length of intermittent window opening should be controlled within 10 h. This study hopes to provide preliminary assistance for subsequent intermittent operation of air handling systems.
