住房和城市发展部（HUD）住宅太阳能供暖和制冷示范项目为600多个太阳能项目提供了资金支持。这些项目提供了目前可用的最大的单一太阳能加热和冷却经验数据库。这些数据表明，项目中的许多主动和被动供暖和生活热水系统的控制存在问题。本文将评估主动系统的运行模式和控制部件按预期运行的能力。示范项目中的大量系统在测试、检验和运行期间遇到控制问题（有238个报告的控制问题涉及192个系统）。故障排除现场访客经常会发现，控制问题导致整个系统瘫痪或部分系统出现故障。 对于更仔细设计的系统（即，辅助蒸馏器功能），其后果并不显著，但对于太阳能辅助接口设计不当的系统，房主往往没有足够的热量。最常见的控制问题涉及系统中的过多模式，因此涉及控制设计；传感器设定点、位置或安装错误；以及与控制器面板之间的接线设计或安装不当。单位:双引文:研讨会，ASHRAE交易，1985年，第91卷，pt。你好，檀香山2B

The Department of Housing and Urban Development (HUD) residential solar heating and cooling demonstration program provided funding support for over 600 solar projects. These projects provide the largest single data base of solar heating and cooling experience now available. These data suggest that controls were problematic in many of the active and passive heating and domestic hot water systems in the program. This paper will assess the active system modes of operation and the control components as to their ability to perform as intended. A large number of systems in the demonstration program experienced control problems during testing, checkout, and operation (there were 238 reported control problems involving 192 systems). Frequently, trouble-shooting site visitors found control problems had disabled the whole system or caused a portion of the system to malfunction. The consequences are not as significant on the more carefully designed systems (i.e., the auxiliary still functions) but, on systems with inappropriately designed solar-,auxiliary interfaces, the homeowners often were without adequate heat.The most common control problems involved excessive modes in system and, therefore, control design;errors in sensor set points, location, or installation;and poorly engineered or installed wiring to and from controller panels.Units: Dual
