摘要
辐射空调近年来在建筑中的应用案例数量上升迅速,如何预测在辐射空调环境下的人体舒适度,成为工程设计参数确定中需要解决的基础问题。本文依据人工环境舱内热反应实验中的实际情况,采用伯克利热舒适模拟软件对地板供冷工况进行模拟得出皮肤温度和热感觉值;将模拟值与实验结果从稳定时间和稳定值两方面进行对比,对该模拟软件在长时间暴露于地板辐射供冷环境中的人体热反应预测的适用性进行验证。结果表明,模型能够在一定程度上反映不对称辐射环境下的人体不同部位皮肤温度分布,以及热感觉和热舒适差异随时间的动态变化过程,大部分部位的偏差在可接受范围内,但在前臂、手背和足背等部位偏差较大,皮肤温度偏差值超过2℃,热感觉偏差接近-1,需通过后续研究进行修正。
In recent years,the application of the radiant air conditioning systems in buildings increases rapidly.How to predict thermal comfort in a radiant air conditioning environment becomes a fundamental problem of engineering design.Based on the actual experimental conditions for a thermal response experiment in the artificial environment room,the Berkeley Comfort Model is used to calculate skin temperature and thermal sensation vote(TSV)in radiant floor cooling environment.The simulated results are compared with the experimental results in terms of the stabilization time and the stability value.The validity and applicability of the software are verified in predicting the thermal response of the human body exposed in the radiant floor cooling environment for a long period.The results show that,the model can predict local skin temperature of human body,the change process of skin temperature,thermal sensation and thermal comfort in asymmetric radiation environment to a certain extent.The deviations of most parts are within acceptable ranges,except those of forearms,hands,and feet.The skin temperature deviation of those parts exceeds 2℃,and the TSV deviation is close to﹣1.So more studies needs to be carried out to update the study.
