针对一种新型半透明光伏-热电制冷辐射窗(STPV-TE-RCW),通过实验和数值模拟方法对其热电性能进行研究,建立STPV-TE-RCW计算模型,验证其准确性,并针对STPV-TE-RCW中的热电模块不同排列形式、辐射板尺寸、散热形式等进行优化分析。在考虑结构自身发电量与耗电量关系的基础上,通过分析制冷系统COP和耗电量,认为5块热电片串联2个支路并联的热电模块排列形式,高度为1 m的辐射板尺寸和强制对流的散热形式效果更好,在这种情况下,STPV-TE-RCW的耗电量与发电量之比为0.83,制冷量能承担该结构产生的60%冷负荷,辐射铝板提供的制冷量为63.4 W/m2,热电模块的COP为1.41。
Abstract
In this paper, a new type of translucent photovoltaic thermoelectric refrigeration radiant window (STPV-TE-RCW) was studied on its thermoelectric performance through experimental and numerical simulation methods, and a CALCULATION model of STPV-TE-RCW was established to verify its accuracy. The different arrangement forms, radiation plate size and heat dissipation form of thermoelectric module in STPV-TE-RCW are optimized and analyzed. On the basis of considering the relationship between power generation and power consumption of the structure, through analyzing COP and power consumption of the refrigeration system, it is considered that the arrangement form of thermoelectric modules with 5 thermoelectric plates in series and 2 branches in parallel, the size of radiation plate with a height of 1 m and the heat dissipation form of forced convection are better. In this case, the ratio of power consumption to power generation of STPV-TE-RCW is 0.83, and the cooling capacity can bear 60% of the cooling load generated by the structure. The cooling capacity provided by the radiant aluminum plate is 63.4 W/m2, and the COP of the thermoelectric module is 1.41.
