摘要:
提出了一种新型的太阳能蓄能/蒸发/集热器,建立了蓄能/蒸发/集热器的相变传热数学模型,得到了充灌石蜡或癸酸的蓄能/蒸发/集热器在蓄能过程中温度场和液化率随时间的变化规律.在南京地区春季典型工况下对充灌水、癸酸或石蜡作为蓄能材料的太阳能蓄能/蒸发/集热器管内温度进行了实验对比研究,结果表明充灌石蜡或癸酸等相变材料,可将白天的太阳能储存下来在夜间利用.并对充灌三种介质的蓄能/蒸发/集热器瞬时集热效率随太阳辐射的变化规律进行了研究,分别拟合得到了瞬时集热效率公式,结果表明充灌石蜡的太阳能蓄能/蒸发/集热器瞬时集热效率最高.
Abstract:
A new type of solar energy storage/evaporator/collector is presented. Mathematic model about phase change heat transfer of the storage/evaporator/collector is established. The change laws of temperature field and liquefaction ratioof solar energy storage/evaporator/collector filled with paraffin wax or decanoic acid are achieved. Experimental comparative study of temperature in thesolar energy storage/evaporator/collector is done whenusing water,decanoic acidor paraffin waxas PCM sunder the typical operating conditions in spring in Nanjing. The result shows that the solar energy storedduring the day can beused at night when PCMs asdecanoic acidor paraffin wax has been filled in. And comparative study of instantaneous collection efficiency of thesolar energy storage/evaporator/collector is done when using water,decanoic acidor paraffin wax. The change laws that variates with solar radiation is achieved. The formula of collection efficiency with three different medium have been fitted. The results indicate that the solar energy storage/evaporator/collector filled with paraffin wax has the highest instantaneous collection efficiency.
