太阳能-空气源热泵热水系统新型组合优化设计
摘要:太阳能-空气源热泵热水系统(solar-air source heat pump hot water system, SAHWS)常用于宿舍楼宇供暖，通过对系统参数的优化设计可显著提高系统能效性能与环境友好性。为得到一种综合考虑SAHWS经济、能源、环保与节能的优化方法，提出了一种新型组合优化设计策略，并利用TRNSYS软件搭建系统仿真模型，以西安、西宁、拉萨这3座不同太阳能资源等级城市为例，对SAHWS运行工况对比分析。结果表明：与常用生命周期成本设计相比，所提出的组合优化设计不仅降低了系统成本，还有着较低的系统能耗；组合优化设计的热泵能耗与工作小时数最短，且有最低的热损，在投资成本、系统季节性能因子、太阳能保证率以及碳粉尘、二氧化碳排放量均有较好表现。
Abstract：Solar-air source heat pump hot water system (SAHWS) is commonly used in dormitory building heating, through the optimization of system parameters can significantly improve the energy efficiency and environmental friendliness of the system. In order to obtain an optimization method that comprehensively considers the SAHWS economy, energy, environmental protection and energy saving, this paper proposed a new combination optimization design strategy, and used TRNSYS software to build a system simulation model. Taking Xi'an, Xining and Lhasa, which are three cities with different levels of solar energy resources, as examples. Comparative analysis of SAHWS operating conditions. The results show that compared with the common life cycle cost design, the proposed combinatorial optimization design not only reduces the system cost, but also reduces the system energy consumption. The heat pump designed by combination optimization has the shortest energy consumption and working hours, and has the lowest heat loss. It has better performance in investment cost, system seasonal performance factor, solar energy guarantee rate, carbon dust and carbon dioxide emissions.
