摘要
为充分响应国家节能减排号召,提高可再生能源的应用水平,针对济南市某100 m^2办公室进行PVT耦合水源热泵的模拟分析,应用Trnsys软件对PVT系统的光电转换效率、集热效率进行模拟,发现PVT综合效率较普通光伏板提高23%;对系统各部分温度进行模拟分析,发现此技术可较好满足热泵供暖工况及室内舒适性的要求;对系统COP进行模拟,发现热泵COP平均值为5.5,系统COP平均值为4.5,相比于空气源热泵具有较高的能效比;对系统的经济成本进行了评估,得出此系统年净收益9750元,约7年的投资回收期,具有很好的经济性。
In order to fully respond to the national call for energy conservation and emission reduction and improve the application level of renewable energy,a PVT coupled water source heat pump was simulated and analyzed in a 100 m2 office in jinan city.Trnsys software was applied to simulate the photoelectric conversion efficiency and heat collection efficiency of the PVT system.The simulation analysis of the temperature of each part of the system shows that this technology can meet the requirements of heat pump heating condition and indoor comfort.Through the simulation of COP of the system,it is found that the average COP of the heat pump is 5.5 and the average COP of the system is 4.5,which has a higher energy efficiency ratio than that of the air source heat pump.After evaluating the economic cost of the system,it is concluded that the system has an annual net income of 9750 yuan and a payback period of about 7 years.
