摘要
本文详细说明了上海海洋大学新校区大学生生活区太阳能热水系统改造工程。首先分析了原热水系统的运行原理和缺陷,提出原热水系统的基础上添加空气源热泵机组,形成新的热水系统,并对热泵机组进行了选型计算。最后通过热水系统改造前后的水、电和天然气的实测消耗量分析了其综合能耗和运行费用。分析结果表明,改造后热水系统的综合能耗减少约21.72%,运行费用减少约23.63%。说明热水系统的改造是成功的。
The innovation of solar water heating system of students living community in Shanghai Ocean u- niversity is illustrated in this paper. Firstly, the operation principle and defects of the original hot water system are analyzed. Secondly, a new hot water system including air source heat pump is established and heat pump units selection is performed. Finally, the comprehensive energy consumption and operating cost of innovation system is compared to those of original system. The results show that the comprehensive energy consumption is reduced by about 21. 72% and operating costs decreased by approximately 23.63%, which means the reconstruction of the hot water system is successful.
