Abstract A validated analytical model is proposed to quickly calculate the transient indoor air temperature and wall temperature by using Laplace transformation and the method of constant variation. The analytical model is further combined with predicted mean vote (PMV) model to evaluate the indoor thermal environment. The quantitative influence of occupants’ ventilation behavior (OVB) during the off-periods on indoor thermal comfort is studied for an intermittent heating (IH) room in the whole heating season. The results indicate that the OVB during the off-periods of IH system can significantly reduce the indoor thermal comfort level during the heating periods. The predictive model of minimum PMV during the heating periods is thus determined to provide a theoretical basis for balancing the OVB during the non-heating periods and indoor thermal comfort during the heating periods. In addition, considering the occupants who have the need for both ventilation and indoor thermal comfort, preheating may be a solution while the heating energy consumption will be increased. The increasing rate of heating energy consumption is approximately 32.5%–74.9%. To reduce the extra heating energy consumption caused by the preheating, occupants need to limit the OVB during the non-heating periods of IH system.

间歇供暖建筑停电期居住者通风行为对室内热环境的影响

摘要 提出了一种经过验证的解析模型，利用拉普拉斯变换和恒变法快速计算瞬态室内空气温度和壁温。该分析模型进一步结合预测平均投票（PMV）模型来评估室内热环境。研究了间歇供暖（IH）房间在整个采暖季节关闭期间居住者的通风行为（OVB）对室内热舒适性的定量影响。结果表明，IH系统关闭期间的OVB可以显着降低供暖期间的室内热舒适度。从而确定采暖期最小PMV预测模型，为平衡非采暖期OVB和采暖期室内热舒适性提供理论依据。此外，考虑到居住者同时需要通风和室内热舒适，预热可能是一个解决方案，但会增加采暖能耗。供热能耗增长幅度约为32.5%~74.9%。为了减少预热带来的额外加热能耗，居住者需要在 IH 系统的非加热期间限制 OVB。预热可能是一种解决方案，但会增加加热能耗。供热能耗增长幅度约为32.5%~74.9%。为了减少预热带来的额外加热能耗，居住者需要在 IH 系统的非加热期间限制 OVB。预热可能是一种解决方案，但会增加加热能耗。供热能耗增长幅度约为32.5%~74.9%。为了减少预热带来的额外加热能耗，居住者需要在 IH 系统的非加热期间限制 OVB。
