ASHRAE标准委员会的一个项目委员会目前正在考虑对太阳能生活热水（SDHW）系统进行评级的测试程序。该程序要求整个SDHW系统在实验室中组装，并且该系统受到控制系统性能的环境条件的特定日变化的影响，例如入射太阳辐射和环境温度，同时该系统在规定的温度、时间和全天抽取率下提供热水。测试将继续进行，直到连续几天系统性能接近相同。建议额定值为准稳态条件下的每日“部分节能”。实际的集电极阵列可以使用太阳能模拟器进行辐照。或者，组成阵列的收集器模块可以按照ASHRAE标准93单独测试- 77，用于计算指定系统测试条件下阵列热输出的结果，以及在使用常规能源进行系统测试期间提供给系统的热输出。本文的目的是描述拟议的测试程序，提出在实验室完成收集器阵列热输出模拟的替代方法，并报告国家标准局为验证该程序而取得的进展。引文:研讨会，ASHRAE交易，第86卷，第一部分，加利福尼亚州洛杉矶

A procedure of testing for rating solar domestic hot water (SDHW) systems is currently under consideration by a project committee of the ASHRAE Standards Committee. The procedure requires that the entire SDHW system be assembled in the laboratory and that the system be subjected to specific diurnal variations of the environmental conditions controlling the system performance, such as incident solar radiation and ambient temperature, while the system supplies hot water at specified temperature, times, and draw rate throughout the day. The test continues until the system performance is near-identical for successive days. It is proposed that the rating be the daily "fractional energy savings" under this quasi-steady-state condition. The actual collector array can be used and irradiated with a solar simulator. Alternately, the collector module comprising the array can be tested separately following ASHRAE Standard 93-77, the results used to compute the thermal output of the array under the specified system test conditions, and this thermal output supplied to the system during the system test using a conventional energy source.The purpose of this paper is to describe the proposed test procedure, suggest alternate ways the simulation of the collector array thermal output can be accomplished in the laboratory, and report on progress being made at the National Bureau of Standards to validate the procedure.
