摘要
为解决河北农村建筑清洁供暖问题和太阳能利用具有不稳定性问题,设计了太阳能PV/T+相变能与直蒸式水源热泵供热(冷)系统进行实验研究。实验结果表明,冬季典型日系统发电量为4.453kWh,制热系数COP平均值3.41;夏季典型日系统发电量为5.945kWh,制冷系数EER平均值3.2;将发电量用于系统运行,制热系数COP为4.22,制冷系数EER为4.19,分别提高了23.75%和30.12%;夏季单纯PV/T太阳能电池发电量5.537kWh,本系统的发电量提高了7.37%。该系统经济效益高,运行稳定,是一种实现河北农村清洁供暖有效途径。
In order to solve the problem of clean heating and the instability of solar energy utilization in rural buildings in Hebei province,solar PV/T+phase change energy and direct evaporation water source heat pump heating(cooling)system were designed for experimental research.The experimental results show that the typical daily power generation in winter is 4.453kWh,and the average heating coefficient COP is 3.41.The typical daily power generation of the system in summer is 5.945kWh,and the average value of the cooling coefficient EER is 3.2.The heating coefficient COP and cooling coefficient EER are 4.22 and 4.19 respectively,which are increased by 23.75%and 30.12%respectively.In summer,the power generation of pure PV/T solar cells is 5.537kWh,and the power generation of this system is increased by 7.37%.The system has high economic benefit and stable operation,and is an effective way to realize clean heating in rural areas of Hebei Province.
