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.
Abstract
In order to realize full-solar heating of rural residential buildings,this study de-signed 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 are-a,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 in-door temperature of the photothermal heating system fluctuated greatly.Furthermore,the collector area and water tank volume required by the photothermal heating system are signif-icantly larger than that of the PV/T photoelectric heating system.Compared with conven-tional 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.
