平均预测不满意百分比（APPD）是表示加热空间热舒适条件的合适方法。因此，APPD为各种供暖系统设计的比较提供了依据。为了进行这项研究，PSU-MRT计算机程序进行了扩展，包括两个子程序。这些子程序确定占用区域的APPD，并通过两种不同的方法计算给定条件空间的热损失。在对PSU-MRT进行修改后，该计划被用于评估当前接受的低温辐射供暖应用设计方法的某些方面。关于最佳辐射板位置和空间预测的建议- 对热负荷进行了分析。这项研究的结果表明，可能有必要对当前的设计方法进行修订。提供了常规确定的热损失值的修正系数和有限情况下面板位置的指南。关键词:辐射供暖，热舒适，计算机程序，计算，位置，热损失，辐射板，空间供暖，热负荷，设计。引用:研讨会论文，佐治亚州亚特兰大，1990年

The average predicted percentage dissatisfied (APPD) is an appropriate means of expressing the thermal comfort conditions of a heated space. Therefore, APPD provides a basis for comparisons of various heating system designs. In order to perform this study, the PSU-MRT computer program was expanded to include two subroutines. These subroutines determine the APPD of the occupied zone and calculate, by two different methods, the heat loss for a given conditioned space. Following the modifications to PSU-MRT, the program was used to evaluate certain aspects of the currently accepted design methodology for low-temperature radiant heating applications. Recommendations concerning optimal radiant panel location and the prediction of space-heating loads were analysed. The results of this study suggest that revisions to the current design methodology may be necessary. Correction factors for conventionally determined heat loss values and guidelines for panel location in limited cases are provided.KEYWORDS: radiant heating, thermal comfort, computer programs, calculating, location, heat loss, radiant panels, space heating, heat load, designing.
