- 摘要
- 太陽能熱水系統技術在國內已相當成熟，多數家戶以安裝平板型太陽能熱水器來產生熱水，本 研究以全國30個氣象站之經典氣象年數據作為氣象資料來模擬太陽能面蓋式熱水器，並據以計算太 陽能熱水器所配置輔助電熱棒所需電量，及使用太陽能熱水器的太陽分率；此處所指之太陽分率為 太陽能熱水器所吸收太陽能與實際洗澡或其他熱能應用所使用熱能二者間之比率。在模擬夏季及冬 季之洗澡水時，水溫分別設定40度及45度，若洗澡前儲水桶溫度未達到55度設定值，則啟動電熱棒 加熱至設定值。北部地區輔助電熱棒所需年耗電量在1,208到2,041度電間，年太陽分率落在58.9到 71.6%間，其中竹子湖與鞍部之耗電量相對最高且太陽分率在59%上下，原因為這兩氣象站位於山 區易形成雲霧導致日射量低，環境溫度也低。中部地區年耗電量在630到920度電間，年太陽分率落 在78.3到84.8%間。南部地區年耗電量在496到666度電間，年太陽分率落在83.6到87.4%間，而以恆 春的年太陽分率87.4%居全國之冠。東部地區年耗電量在633到1,368度電間，年太陽分率落在67.8 到84.1%間，其中宜蘭、蘇澳與花蓮因秋、冬之際會受到東北季風的影響，年耗電量因此居高且年 太陽分率變低。離島部分因所處地理位置差異大，年耗電量在828到1,656度電間，年太陽分率落在 65.5到80.4%間。高山地區年耗電量在1,471到2,872度電間，年太陽分率落在58.4到69.8%間。整體來 看，本島的年耗電量/太陽分率呈現中南部低/高於東北部的走向。

- Application of the solar water heater (SWH) is popular nowadays in Taiwan. The most installed SWHs are of flat-plate type and for household uses. Simulation of a flat-plate SWH is made to calculate electricity need for the auxiliary heating rod and solar fraction using the weather data of a typical meteorological year for thirty weather stations distributed in Taiwan. The bathwater temperatures are respectively set to be 40oC (in summer) and 45oC (in winter). If the water temperature of the hot-water storage tank does not reach the set temperature (55oC) at 17:00 each day, the SWH then turns on the auxiliary heating subsystem to raise water temperature to the set temperature. In the northern Taiwan, the annual electricity consumption and solar fraction are between 1,208 and 2,041 kWh as well as 58.9 and 71.6%, respectively. The annual solar fractions of Zhuzihu and Anbu are around 59% because they are located in a mountainous area with frequent clouds and fog leading to low solar radiation and low ambient temperatures. The annual electricity consumption and solar fraction in the central Taiwan are between 630 and 920 kWh as well as 78.3 and 84.8%, respectively. The annual electricity consumption and solar fraction in the southern Taiwan are between 496 and 666 kWh as well as 83.6 and 87.4%, respectively. Hengchun has the highest annual solar fraction, 87.4% among 30 weather stations in Taiwan. The annual electricity consumption and solar fraction in the eastern Taiwan are between 633 and 1,368 kWh as well as 67.8 and 84.1%, respectively. Hualian, Suao and Yilan are affected by the northeast monsoon and lead to high annual electricity consumptions and low solar fractions. In the outlying islands, the annual electricity consumption and solar fraction are between 828 and 1,656 kWh as well as 65.5 and 80.4%, respectively. The annual electricity consumption and solar fraction in the high mountain areas are between 1,471 and 2,872 kWh as well as 58.4 and 69.8%, respectively. Overall, the average annual electricity consumption/solar fraction is higher/lower in the northeast parts than those in the central and south parts of Taiwan.
