自然通风建筑热舒适评价模型

Thermal comfort evaluation models for naturally ventilated buildings

针对自然通风建筑环境内预计平均热感觉指数PMV与实际热感觉投票值TSV有明显偏差的问题,总结分析了目前自然通风建筑热舒适评价模型的研究成果,介绍了PMV修正模型和适应性模型以及将二者结合的预测适应性平均热感觉aPMV模型。结果表明,3种评价模型均可预测自然通风建筑的热舒适性,但各有优缺点。虽然目前我国已有针对自然通风建筑的热舒适性评价标准,但PMV模型与适应性模型相结合的研究还不够,二者结合的作用机理尚不完全明确。如何利用已有的评价模型指导自然通风建筑的设计和运行,使之发挥更大的节能潜力是未来自然通风建筑热舒适性研究的方向之一。

Aiming at the problem of significant difference between the predicted mean vote（PMV）and the thermal sensation vote（TSV）under naturally ventilated building environment,summarizes the researches on thermal comfort evaluation models under naturally ventilated building environment.Presents the PMV correction model,the adaptive model and their combination model—the adaptive predicted mean vote（aPMV）model.The results show that the three evaluation models can predict the thermal comfort of naturally ventilated buildings with their own advantages and disadvantages.Although there is a standard for evaluating the thermal comfort of naturally ventilated buildings,the study of the combination of PMV model and adaptive model is not enough,and the mechanism of their combination is not yet clear.How to use the existing evaluation model to guide the design and operation of naturally ventilated buildings and make it more energy efficient is one of the important directions of future research on naturally ventilated building thermal comfort.
