1974年，国家标准局（NBS）发布了一项基于热性能测试和评级太阳能集热器的拟议程序[1-3]。该程序规定，应进行一系列室外稳态试验，以确定集热器在一定温度范围内的近太阳能n06n效率。美国供暖、制冷和空调工程师协会（ASHRAE）最近采用了ASHRAE标准93-77[4]。它与原始NBS程序类似，但需要进行额外的测试，以确定收集器时间常数以及可应用于近场的入射角修正系数- 太阳能午间效率可以决定采集器在清晨和傍晚的性能。NBS根据ASHRAE标准93-77建造了两个测试设施，一个用于模块化水冷集热器，另一个用于空气加热器。本文的目的是描述最近采用的测试程序，提供NBS设施的说明，并给出根据该标准在几种商用收集器上进行的一系列完整测试的结果。引文:新墨西哥州阿尔伯克基市阿什雷学报第84卷第2部分

A proposed procedure for testing and rating solar collectors based on thermal performance was published by the National Bureau of Standards (NBS) in 1974 [1-3]. The procedure prescribed that a series of outdoor steady-state tests be conducted to determine the near-solar-n06n efficiency of the collector over a range of temperature conditions. The American Society of Heating, Refrigerating and Air-Conditioning Engineers (ASHRAE) has recently adopted ASHRAE Standard 93-77 [4]. It is similar to the original NBS procedure but calls for additional tests to determine the collector time constant as well as an incident angle correction factor that can be applied to the near-solar-noon efficiency to determine collector performance both early in the morning and late in the day.Two test facilities have been built at NBS in accordance with ASHRAE Standard 93-77, one for modular water-cooled collectors and the other for air heaters. The purpose of this paper is to describe the recently adopted test procedure, provide a description of the facility at NBS, and to give results of a complete series of tests made according to the Standard on several commercially available collectors.
