摘要
为实现农村住宅建筑的全太阳能供暖,设计了光热供暖和光伏光热一体化(PV/T)光电供暖2种全太阳能供暖系统。以拉萨为典型地区,使用TRNSYS软件模拟分析了2种系统的运行性能和经济性,并进行了对比分析。研究发现,经过合理的设计,2种系统均可以满足室内供暖需求,相比之下,光热供暖系统的室内温度波动较大,而PV/T光电供暖系统可以实现稳定的室内温度。此外,光热供暖系统所需的集热器面积和水箱体积均明显大于PV/T光电供暖系统。与常规供暖系统相比,光热系统和PV/T光电系统的投资回收期分别为5.87年和2.3年。因此,PV/T光电供暖系统在农村单体式住宅建筑中更具有应用前景。
In order to realize full-solar heating of rural residential buildings,this study designed two types of full-solar heating systems,that are photothermal heating systems and photovoltaic/thermal(PV/T)photoelectric heating systems.Taking Lhasa as a typical area,this study simulated the operation performance and economy effect of the two systems by using TRNSYS software and made a comparative analysis.The results showed that the two systems could both satisfy the needs of indoor heating through reasonable design.The PV/T photoelectric heating system can achieve stable indoor temperature,while in contrast the indoor temperature of the photothermal heating system fluctuated greatly.Furthermore,the collector area and water tank volume required by the photothermal heating system are significantly larger than that of the PV/T photoelectric heating system.Compared with conventional heating systems,the payback periods of the photothermal heating system and the PV/T photoelectric heating system are 5.87 years and 2.3 years respectively.Therefore,PV/T photoelectric heating system has more application prospects in the single residential buildings in rural areas.
