熱活化建築系統效能研析
Performance Analysis of the Thermally Activated Building Systems
摘要
本研究提出了一套熱活化建築系統，旨在將水管埋於樓板中藉由其熱輻射效應以供應建築室內空調，並應用於台灣各地的冬季氣候以評估系統效能與適用性。首先以參考文獻[9]所述比利時氣候在10.8m x 27m x 3m 的標準辦公大樓建築物作為本文的模擬基準，比較該文使用TRNSYS 軟體與本研究採用eQuest 軟體模擬建築耗能結果差異，其結果顯示雖因不同軟體的氣象數據資料不同，而呈現平均約4℃的室外溫度差異，但兩者模擬結果溫度及耗電量變化趨勢甚為一致。再 將TABS 搭配台灣各地氣候(如輸入台北、台中、高雄及花蓮等地)，比較其空調負荷及溫度變化，發現將熱活化建築系統用於台北地區比台灣其他地區效益較大。改變建築物其他參數(如外牆及玻璃窗戶)，當外牆採用鋼筋混凝土牆時，總耗電量會提昇60％。但使用單層玻璃之窗戶，總耗電量只提昇5％，顯示選用U 值較好的外牆，可節省更多的能量。此系統應用於台北氣候與電暖器比較節能約達10％。

This study presents a thermally activated building system (TABS). In practice, a TABS, formed by the water pipes embedded into the ground floor, can provide HVAC (heating, ventilation, and air conditioning) via the thermal radiation process for indoor environmental comfort. Considering the simulations for a typical 10.8m x27mx3m workplace building in Belgian, the energy characteristics were calculated using the eQuest software and compared with the predictions by the TRNSYS software from Saelens et al [9]. Numerical computations indicate that the predicted results of temperature and energy demand from eQuest were consistent with those from TRNSYS in trend. Then, the eQuest software was also applied using the baseline air conditioning loads to test the performance and adaptability of the TABS system during the winter climate conditions (in Taipei, Taichung, Kaohsiung, Haulian) of Taiwan. Based on the comparison of the profiles of cooling load and temperature, the simulated results indicated the energy saving with TABS can be up to 10% as compared to the traditional air condition (without using TABS) in Taipei.
