摘　　要：基于温度型Block-Gebhart(B-G)模型,考虑渗透风、下送热风上浮和湿源散湿等因素,建立了冬季特征的全热B-G模型,以预测冬季大空间室内热环境和供热效果。基于某采用下送风分层空调的大空间建筑,建立了6个分区的冬季全热B-G模型,以6个工况的实验条件预测了对应的理论热环境与热负荷。实验验证表明:室内各区空气温度、壁面温度、空气比焓的平均绝对相对误差的均值分别为4.75%、4.33%、2.80%;各工况热负荷预测值与实验值相对误差为-14.78%~-0.22%。所建模型拓展了B-G模型在冬季和有湿源情况下的应用。Based on the temperature-type Block-Gebhart(B-G) model,considering the air infiltration,air floating of low-side wall air supply and moisture source dissipation,this paper establishes a B-G model of total heat to predict the indoor thermal environment and heating effect of large space buildings in winter.The B-G model of total heat in winter is built and divided into six zones for a large space building with low-side wall air supply system.The corresponding theoretical thermal environment and heating load are predicted according to the six experimental conditions.The experimental results show that the average value of the mean absolute relative error of air temperature,wall temperature and air enthalpy is 4.75%,4.33% and 2.80%,respectively,and the relative errors of predicted and experimental heating load are-14.78% to-0.22%.This model extends the application of B-G model with moisture sources in winter.
