Simplified Models for Air Stratification and Thermal Comfort in Atria 中庭空气分层和热舒适的简化模型
介绍了线性温度分层模型与ISO 7730计算热舒适性的结合。该模型被集成到一个动态的单区能源模拟程序中。根据分层空气温度和中庭的计算表面温度,计算五个位置的热舒适度。以小时和累积曲线的形式显示结果,并将小时数据与测量值进行比较。模拟表明,与简化方法的预期值相比,模拟结果与测量值存在一些偏差。 对结果进行分析,以确定误差的主要来源。坚持认为,尽管结果不太准确,但像这样的工具在设计和改造过程中非常有价值,因为它们具有广泛的可用性和简单的应用。它们可能会阻止在早期阶段进行重新设计。关键词:1995年,计算,中庭,热舒适,温度分层,空气,准确性,比较,计算机编程。研讨会,ASHRAE Trans。1995年,第101卷,第2部分
Presents the combination of a linear temperature stratification model and the use of ISO 7730 for calculating thermal comfort. The model is integrated into a dynamic, single-zone energy simulation program. Based on the stratified air temperature and calculated surface temperatures of an atrium, calculates thermal comfort for five locations. Presents the results as hourly and accumulated curves, and compares hourly data to measurements. States the simulations show some deviations from the measured values, as expected for the simplified approaches. Analyses the results to locate the main sources of errors. Maintains that in spite of the less accurate results, tools like this are of great value in design and retrofit processes because of their wide availability and simplicity of application. They may prevent the need for redesign at an early stage.KEYWORDS: year 1995, Calculating, atria, thermal comfort, temperature stratification, air, accuracy, comparing, computer programs
