关于美国URD标准中室外空气计算参数的探讨
摘要：在我国基于URD标准编制的不同标准中，对于室外空气计算参数的定义存在一些出入。为厘清URD标准中这些室外空气计算参数的内涵，本文对URD标准中的不保证率及对应湿球温度进行了研究，明确了以下几点：URD标准中1%不保证率的定义是季节不保证率；ASHRAE标准中的年不保证率可以与GB 50019—2015标准中的累年平均每年不保证小时数进行等效转化；URD中的对应湿球温度，实质为所有对应湿球温度的最高值。
关键词：室外空气计算参数URD标准不保证率对应湿球温度季节不保证率年不保证率

Discussion on outdoor air design parameters in American URD standard
Abstract: There are some differences in the definition of outdoor air design parameters in different standards based on the URD standard in China. To clarify the connotation of these outdoor air design parameters in the URD standard, the non-guarantee rate and the coincident wet-bulb temperature in the URD standard are studied in this paper, and the following points are made clear: 1% non-guarantee rate in the URD standard is defined as seasonal non-guarantee rate, and the annual non-guarantee rate in the ASHRAE standard can be equivalent to the annual average non-guarantee hour number per year in GB 50019-2015 standard. The coincident wet-bulb temperature in the URD standard is essentially the maximum of all coincident wet-bulb temperatures.
Keywords: outdoor air design parameter; URD standard; non-guarantee rate; coincident wet-bulb temperature; seasonal non-guarantee rate; annual non-guarantee rate;
