開放式冷藏櫃均溫設計之研究

Thermal Uniformity Design of Open Refrigerated Display Case

摘要


本文利用實驗及數值模擬方式探討展示櫃背板開孔分佈設計對均溫性影響,由結果顯示,若開孔分佈集中於下三層時,對本文所研究之展示櫃之均溫性表現最佳,其第三層至第六層棚架內溫度大約都較原始背板開孔分佈平均低2℃。一旦展示櫃具有較佳均溫性,則能降低壓縮機負載,並增加節能的效益。

This paper attempts to investigate the effect of different holey distribution of back panel on the thermal uniformity of open refrigerated display case (ORDC) through the experimental and numerical simulation approaches. The results show that the full holey distribution on the lower three shelves can perform the best temperature uniformity among the all test cases. In this case, the temperature difference from shelf 3 to shelf 6 is lower than that of original design by 2℃, thus it can alleviate the operation load of compressor and increase the energy-saving efficiency of RDCs.
