摘要:
针对夏热冬冷地区家庭供冷、供暖和生活热水需求特点,建立了一套户用太阳能-空气源热泵耦合供能系统.调研形成了夏热冬冷地区住宅用能模型,构建住宅建筑模型,进一步用TRNSYS软件搭建系统仿真模型,模拟系统全年运行并得到相应数据.仿真结果表明:系统全年运行的太阳能集热效率在40%左右,系统能效比为4.45,系统不保证率为0.9%,佐证系统的可行性; 对系统全年能耗进行分类分析,与传统系统进行对比,成本差额动态回收期为11.0 a,年运行费用节省621.8元,年碳排放减少621.2 kg,验证了系统的经济性与环保性; 通过对太阳能集热器面积和贮热水箱体积进行调节模拟确立系统参数的最佳匹配范围,以夏热冬冷地区两居室为例,空气源热泵依据供冷供热负荷选型后,匹配的太阳能集热器面积推荐范围为2.7±0.3 m2、贮热水箱容积推荐范围为0.20±0.05 m3,可为系统的推广应用提供理论依据.
Abstract:
In order to meet the needs of household cooling, heating and domestic hot water in hot summer and cold winter areas, a solar-air source heat pump coupling energy supply system for household is established. The residential energy consumption model in hot summer and cold winter ares is formed through investigation, and the residential building model is constructed. The system simulation model is further built by means of TRNSYS software to simulate the annual operation of the system and obtain the corresponding data.The simulation results show that the annual solar collector efficiency of the system is about 40%, the energy efficiency ratio of the system is 4.45,and the non-guarantee rate of the system is 0.9%, which proves the feasibility of the system. By classifying and analyzing the annual energy consumption of the system and comparing it with the traditional system, it is found that the dynamic payback period of cost difference of the constructed system is 11.0 a, the annual operating cost is saved by 621.8 yuan, and the annual carbon emission is reduced by 621.2 kg, which verifies the economy and environmental friendliness of the system.The optimal matching range of system parameters is established by adjusting and simulating the area of the solar collector and the volume of the hot water storage tank. And then, taking the two-bedroom apartment in hot summer and cold winter area as an exampl, after the selection of air source heat pump according to the cooling and heating load, the recommended range of the matching solar collector area is 2.7 ± 0.3 m2, and the recommended range of hot water storage tank volume is 0.20 ± 0.05 m3, which can provide theoretical basis for the popularization and application of the system.
