Abstract
本研究針對蒸發器回風氣流與表面溫度的分佈狀態開發出可提升窗型空調機性能的空氣分配器，並進行不同配置參數對於窗型空調機性能影響的相關研究。窗型空調機的性能測試參照CNS 14464的T1標準實施。此外為瞭解外氣溫度對於窗型空調機性能的影響，本研究額外增加30 ℃與40 ℃的外氣溫度條件進行窗型空調機的性能實驗。
研究結果顯示，在所有測試條件之下，不同形式的空氣分配器均可明顯地提升窗型空調機的除濕能力且對於空調機的耗電量幾乎沒有影響。S3空氣分配器的冷氣能力、除濕能力以及能源效率比（EER）在外氣溫度30℃的提升率分別比原機高13.70%、59.63%與14.37%；在外氣溫度35℃的提升率分別比原機高6.19%、30.97%與6.75%；在外氣溫度40℃的提升率則分別比原機高5.57%、25.92%與5.84%。故本研究所提出最佳配置的窗型空調機空氣分配器(S3)確實能有效地提升窗型空調機的性能與用電效率。
In this study, the air distributors (AD) for enhancing the performance of the window type air conditioner (WAC) was developed based on the distribution of the return airflow and the surface temperature of the evaporator, and the influence of different configuration parameters on the performance of the window type air conditioner were studied. The performance of WAC was tested under the T1 condition of CNS14464. In addition, in order to understand the effect of outdoor air temperature on the performance of WAC, an additional performance experiment of WAC was carried out by adding the outdoor air temperatures of 30 ℃ and 40 ℃. The results showed that all air distributors could significantly improve the dehumidification capacity of WAC and had little effect on the power consumption of WAC under all test conditions. The enhanced ratio of cooling capacity, dehumidification capacity and energy efficiency ratio (EER) of the WAC with air distributor of S3 was 13.70%, 59.63% and 14.37%, 6.19%, 30.97%, and 6.75%, and 5.57%, 25.92%, and 5.84% that compared with the original WAC at outdoor air temperature of 30, 35, and 40 ℃, respectively. Therefore, this study proposed the optimal configuration (S3) of the AD could effectively improve the performance and electricity efficiency of the WAC.
