陽台樣式與空調室外機配置型態對行人層與陽台內溫度影響之研究

熱島效應導致都市溫度不斷升高，人類對於空調設備也愈加依賴。大量使用空調的代價除了能耗增加，室外機排熱更是造成環境溫度上升，加劇都市熱島效應並形成惡性循環。文獻指出安裝室外機之環境會與空調效能相關，進而調節室外機排氣溫度。陽台作為室外機經常安裝之空間，其空間特質與室外機所排熱氣散熱效率有明顯關聯。本研究綜合外推與內縮陽台、陽台配置置邊與集中設置、室外機置陽台內外側與內側及室外機吹向共計12種方案，並以迎風及背風側探討行人層與低中高三種樓層下陽台內溫度影響。結果顯示陽台設置室外機將影響行人層溫度最多達2.3度，有室外機下外推陽台較內縮普遍擁有較高行人層溫度，但內縮陽台與室外機皆集中並向外側吹方案卻異常高溫達41度。影響陽台內溫度主因為為陽台樣式及配置。迎風面陽台置邊能有效降低陽台內溫度，集中則造成高溫，陽台置邊並且室外機置於陽台內側能造成方案中最低溫度表現，室外機若與內縮陽台皆集中設置將造成最高溫度表現，可達42.1度。背風面陽台集中配置能造成較低陽台內溫度，置邊則導致較高溫度。若室外機與陽台皆置邊配置將造成方案中最高溫度，可達41.5度。陽台集中配置下，室外機安裝在陽台外側能導致方案中最低溫度。

In response to the increased demand for air conditioning among modern people due to the urban heat island effect, this study has designed a total of 12 schemes for balcony and outdoor unit configurations. The study investigates the impact of these schemes on the temperatures within the balconies for pedestrians and occupants on the windward and leeward sides, considering three floor levels: lower, middle, and upper. The results indicate that the outdoor unit significantly affects the temperatures experienced by pedestrians, with balconies having extended outdoor units generally exhibiting higher temperatures compared to balconies with retracting units.The primary factors influencing the temperature within the balconies are the style and configuration of the balconies. On the windward side, placing the balcony at the edge effectively lowers the temperature within the balcony, while a centralized configuration leads to higher temperatures. On the leeward side, a centralized balcony configuration results in lower temperatures within the balcony, while an edge configuration leads to higher temperatures.
