本研究旨於以數值模擬方式探討使用水飽和相變化材料微膠囊層作為光電池系統之被動式溫控元件,藉由相變化過程潛熱吸收使得光電池在日照高峰期間能維持在一定溫度,避免其發電效率因溫度升高而衰退,進而提升光電池模組發電效率之效益。文中針對不同氣候條件、相變化材料熔點和夾層厚度等參數對光電池模組在熱/電方向的效能影響作有系統探討:並進一步考慮具不同熔點雙層相變化微膠囊之光電池模組的系統,探討其適用於較大變動氣候環境的效益。模擬結果顯示,相較於未具相變化微膠囊層光電池模組,具單/雙層水飽和相變化微膠囊之光電池模組在冬季與夏季環境皆有較佳的性能表現。由於冬季之日照輻射與室外溫度較低,單/雙層具相變化微膠囊之光電池模組性能提升量較有限;而在夏季,具單/雙層相變化微膠囊之光電池模組性能則有明顯提升。
The present study via a numerical simulation aims to explore the efficacy of using a single/double layers of water-saturated microencapsulated phase change material (MEPCM) as a passive thermal management medium for a PV module under various daily operation conditions. Parametric simulations have been performed for the thermal /electrical performances of the PV module integrated with single/double layers of MEPCM under different weather conditions, focusing on the effects of varying thickness of the MEPCM layers as well as the melting point of PCM in the MEPCM. The results showed the thermal/electrical performances of PV module may be markedly improved in both winter and summer weather conditions considered by using double layers of MEPCM.
