相变蓄热材料导热系数对太阳能通风墙性能的影响
Effect of Thermal Conductivity on Performance of Solar Chimney With Phase Change Accumulator
摘要
Abstract
The influence of different thermal conductivities of phase change and thermal storage wall on the performance of solar chimney was analyzed and compared through the calculation of the ventilation and heat storage or release change process of the phase change and thermal storage type of solar chimney model.The results show that the maximum.emperature of the heat absorber plate is more close to the phase change temperature with the increase of the thermal conductivity of the phase change and heat storage wall.The average inlet wind velocity reduces with the increase of the thermal conductivity for the process of heat storage,while increases for the process of heat release.The higher the thermal conductivity of the phase change and thermal storage wall is,the higher the cumulative ventilation in 16 hours of the regenerative solar chimney system will be.But when the thermal conductivity is increased to 0.66 W · (m · K)-1,the cumulative ventilation has almost no increase even if increasing the thermal conductivity of the material.关键词
