Poly-generation of cooling,heating and power performance analysis of PV radiant panel PV/T system

提出了一种基于单晶硅太阳能电池的电热冷联产光伏辐射板，将起集散热作用的辐射板与单晶硅光电池组件耦合，通过辐射板管路内流体循环，降低电池工作温度，一方面提高电池发电效率，同时回收利用余热；另一方面，夜间通过辐射制冷方式，获得冷量，从而实现电热冷联产。通过实验测试分析，光伏辐射板同比PV组件发电效率可提高8％～16％，且集热效率达到45％左右，制冷能力为40～80W／m2。

A combined cooling, heating and power mono-silieon solar photovoltaic radiant panel （PV/R） is proposed, which compounds the radiant panel with the PV module. The PV operating temperature is decreased through the internal cycling of liquid pipe of radiant panel. Thus the power efficiency of PV module is increased, at the same time, the heat of PV using for heating can be recollected. While at night, the cooling used for the daytime is collected through the nocturnal cooling storage. In the experiment testing, the PV/R not only increases the power efficiency by 8%-16%, but obtains the heating efficiency by 45% and gets the cooling capacity of 40--80 W/mx.
