太阳能生活热水（DHW）系统的维护要求取决于系统的可靠性。在本文中，评估了五个通用太阳能DHW系统的可靠性，这些系统是典型的安装在美国各地的太阳能DHW系统。可靠性框图用于评估以下条件:冻结、过热和缺乏热水。描述了验证系统性能所需的最低仪器。为太阳能DHW组件和系统的设计师和制造商提出了建议。引文:研讨会，ASHRAE交易，1983年，第89卷，pt。华盛顿特区2B。

The maintenance requirements of solar domestic hot-water (DHW) systems depend on system reliability. In this paper, the reliability of five generic solar DHW systems, which are typical of those installed throughout the United States, is assessed. Reliability block diagrams are used to evaluate the following conditions: freezing, overheating, and lack of hot water. The minimum instrumentation needed to verify system performance is described. Recommendations are presented for designers and manufacturers of solar DHW components and systems.
