【摘要】：空气源热泵辅助太阳能热水系统是目前较常见的热水系统。该系统结合了太阳能热水系统与空气源热泵系统各自的优点,解决了单一的太阳能热水系统在太阳能辐射不足的情况下无法保证供应生活热水的问题。空气源热泵辅助太阳能热水系统的性能主要由太阳能集热器的集热能力及空气源热泵的制热能力来决定。在满足热水需求的前提下,不同面积的集热器与不同容量的空气源热泵机组相匹配,系统的经济效益存在很大的差别。而且在不同的气候区该系统的性能也有所不同。本文针对不同气候区的高校学生宿舍用水情况,研究空气源热泵辅助太阳能热水系统的匹配问题。本文以长沙地区高校学生宿舍生活热水供应为背景,建立空气源热泵辅助太阳能热水系统动态仿真模型并运行分析,研究该系统在设计条件下的全年运行情况,分析设计方案下的太阳能单元与热泵单元的制热量、运行能耗、太阳能保证率、系统COP等性能参数。在此基础上采用正交试验方法研究了不同集热器面积、空气源热泵容量、供热水箱体积相互匹配的系统运行情况,综合考虑系统初投资和运行费用,得出了经济性最优的系统匹配方案。以相同的研究方法分析得出了长沙地区酒店用水模式下的最优匹配方案和广州、昆明两地不同气候条件下的学生宿舍系统最优匹配方案。在以上研究的基础上,本文就最优匹配方案下的空气源热泵辅助太阳能热水系统相对于以燃煤、燃油、燃气三种常规能源为热源的系统进行了对比,分析得出空气源热泵辅助太阳能热水系统具有良好的节能效益、经济效益和环保效益,该系统应得到广泛的推广和应用。
[Abstract]:The solar hot water system of air source heat pump assisted is far more common in hot water system. This system combines the advantages of solar hot water system and air source heat pump system respectively, to solve the solar water heating system in the solar radiation is not enough single case can not guarantee the supply of living hot water. The heating capacity of heat collecting capacity and air source heat pump the performance of a solar hot water system of air source heat pump assisted mainly by the solar collector to decide. In order to meet the demand for hot water under the collector area of different and different capacity of the air source heat pump unit, there is great difference in the economic benefit of the system. And the performance of the system in different climate zones are different. According to the different climatic zones of university dormitory water, matching the solar hot water system of air source heat pump assisted research in this paper. To Changsha area university student dormitory life hot water supply as the background, and establish dynamic simulation model of solar hot water system and air source heat pump assisted operation analysis, research the operation situation of the system under design conditions, analysis of design of the solar heat pump unit and unit heat capacity, energy consumption, solar fraction, COP system etc. performance parameters. On the basis of using the orthogonal test method of different collector area, air source heat pump capacity, the operation of the system of heating tank volume matching, considering the system initial investment and operation cost, the matching system of economy optimal solution. In the same research method analysis of the optimal Changsha District Hotel water mode matching method and optimal climatic conditions in Kunming Guangzhou, two under the dormitory system on the above matching scheme. Based on the optimal matching of air source heat pump assisted solar hot water system under the plan with respect to coal, fuel gas, three kinds of conventional energy compared to the heat source system, analysis of solar hot water system of air source heat pump assisted with such good benefits, economic benefits and environmental benefits, the system should be promoted and a wide range of applications.
