目前，TRNSYS、f-CHART和SOLCOST三个计算机程序被广泛用于太阳能空间供暖和生活热水系统的设计和评估。尽管他们的预测被广泛使用，但其准确性还需要通过实验数据来验证。为了提供太阳能生活热水系统计算机程序验证所需的数据，美国国家标准局的工作人员在马里兰州盖瑟斯堡制造并安装了六个典型系统。这些系统自1978年6月开始运行。 本文描述了所做的测试、实验结果，并将实验结果与运行前12个月的计算机预测进行了比较。引文:研讨会，ASHRAE交易，第86卷，第一部分，加利福尼亚州洛杉矶

Currently three computer programs, TRNSYS, f-CHART, and SOLCOST, are being extensively used for the design and evaluation of solar space heating and domestic hot water systems. Although widely used, the accuracy of their predictions needs to be verified with experimental data. In order to provide data required for the validation of these computer programs for solar domestic hot water systems, the staff of the National Bureau of Standards fabricated and instrumented six typical systems at its Gaithersburg, MD site. The systems have been operating since June, 1978. This paper describes the testing done, the experimental results, and compares the experimental results with the computer predictions for the first twelve months of operation.
