为研究太阳能生活热水系统的应用效果,通过实地检测和问卷调研,分析目前住宅集中式太阳能生活热水系统在评价和设计中存在的问题。研究表明,在进行太阳能热水系统工程测评时,应通过检测计算系统中“两进两出”的热量平衡关系,以太阳能利用率、常规能源有效替代率和系统散热比为主要评价指标。在进行太阳能热水系统设计时,应结合用户实际使用需求确定设计参数,确定“太阳能部分替代,常规能源保证”的主从关系。
In order to study the application effect of solar hot water system, the problems existing in the evaluation and design of centralized solar hot water system in residential area are analyzed through field test and questionnaire survey. The research shows that in the evaluation of solar hot water system engineering, the heat balance of “two in and two out” in the calculation system should be taken as the main evaluation index in terms of solar energy utilization ratio, effective replacement rate of conventional energy and system cooling ratio . In the design of solar hot water system, the design parameters should be determined according to the actual needs of the user to determine the master-slave relationship of “partial substitution of solar energy and regular energy guarantee”.
