| 中文摘要 | 本報告以簡易矮架溫室栽培設施設置於住宅屋頂,選定宜蘭農工教師單身宿舍頂 樓兩個房間作對照組,並設置個人電腦測定系統將所測定之溫度、熱流及樓版水平日輻射量 等實際資料記錄於個人電腦從事比對分析,經夏季實測三個月記錄分析可知,矮架溫室及其 上方架設黑網置於建築物頂樓,其對頂樓室內之隔熱效果相當顯著,對照組之樓版外側表面 溫度兩者最大相差 16 ℃,白天室內溫度平均相差 2 ∼ 3 ℃,並由實測結果可推算減少了 約 90% 之熱能直接經由樓版進入室內。 是故此方式對於改善建築物室內熱環境,降低建築 物熱負荷以減少空調能源消耗,具有相當效果,並兼具綠化及栽植生產作物等經濟效益。 |
| 英文摘要 | The purpose of this paper was to study the indoor thermal environment due to the installation of the small-framework greenhouses on the top of buildings. For the experimental area of this study, a living room, denoted as Lab #1, on the top floor of a dormitory located at National I-Lan Institute of Agriculture and Technology was selected; another similar type of living room was chosen for comparison. Two arrangements were used in this experiment. They were: (1) The greenhouses with 50% transparency sunshade-net were set on the roof right above Lab #1, but not set for Lab #2. (2) The personal computer measurement system was instlled to measure the temperatures of inner and outer surfaces of the roof, indoor air temperatures of the two Labs, outdoor air temperature, heat flux through the roof of the rooms, and horizontal solar radiation intensity of the roof surface. The study was finished in three months and can be conclueda as follows: (1) For the highest temperature collected on the outer surface of each roof, there was a a significant difference of 16 ℃ between these two labs. The difference may explain the indoor air temperature for lab#1 is 2 ∼ 3 ℃ lower in comparison with Lab#2. (2) Heat flux through the multi-layer slab of the roof was measured by heat flux meters. Quantitatively speaking, the heat flux at Lab#1 was decreased to about 10% of that at lab#2. In summary, by using the greenhouses in this study, the thermal load on buildings can be efficiently reduced to moderate both indoor thermal environment and summertime air-conditioning requirements. |
