On the Preparation of Climatic Design Criteria for Solar Space-Heating Systems in a Cloudy Climate 多云气候下太阳能空间供暖系统气候设计准则的编制
本文介绍了一种编制气候设计标准的方法,该标准独立于硬件配置,可在之后纳入,并根据具体情况进行定制。原则上,在多云气候的冬季,太阳能空间供暖系统的性能评估被简化为一个参数,即入射的全球太阳辐射水平。该方法以美国亨茨维尔市为例,证明了较温和的冬天可能比较寒冷的冬天带来更多问题。它还表明,太阳辐射的月平均值或小时平均值(按月)可能会对太阳能空间供暖系统的性能产生偏差。 此外,来自建模工作的气候数据允许工程师分析太阳能空间加热系统的容量需求和成本效益,而无需来自实验太阳能空间加热系统的数据。引文:研讨会,ASHRAE交易,第87卷,第一部分,伊利诺伊州芝加哥
A methodology is presented for the preparation of climatic design criteria independent of hardware configuration which can be incorporated afterwards and tailored to the individual case. In principle, the performance evaluation of a solar space heating system during winter in a cloudy climate is reduced to one parameter So, the level of the incoming global solar radiation.The method is exemplified for Huntsville, AL. It proves that milder winters may pose more problems than colder winters. It is also illustrated that monthly means of the solar radiation or hourly means (by month) may produce a biased picture of performance of solar space heating systems. Furthermore, the climatic data from the modeling effort permit the engineer to analyze capacity requirement and cost effectiveness of solar space heating systems without the necessity of data from experimental solar space heating systems.
