摘要
以热力学第一、二定律为基础,对太阳能热泵系统的各主要部件进行分析,给出系统各环节的能量分析模型和分析模型。选取北京某典型别墅作为太阳能热泵系统的应用对象,模拟系统效率随太阳能集热器面积和储水箱体积的变化,获得相应参数的最佳配比。结果表明:COP分析和代价效率分析一致,系统在集热器面积为127.98 m^2,水箱体积为9.08 m^3时达到最优;集热器面积为127.98 m^2,水箱体积为3.936 m^3时系统效率最大。
Based on the first and second law of thermodynamics, the major components of solar-assisted heat pump sys- tem were researched. Energy analysis model, exergy analysis model and evaluation index of every link in the system were given. The solar-assisted heat pump system was applied to a representative villa in Beijing. How system efficiency varied with the change of solar collector area and storage tank volume was simulated, and the optimum ratio of corresponding pa- rameters was obtained. The results show that the COP analysis and cost exergy efficiency analysis are consistent. The sys- tem is optimal when the collector area is 127.98 m2 and the tank volume is 9.08 m3. The exergy efficiency of the system reaches a maximum when the collector area is 127.98 m2 and the tank volume is 9.08 m3.
