儲冰空調系統應用於國家級音樂廳可行性評估

國家音樂廳依98年空調運轉資料及兩廳院的營運特性中，發現空調負荷特性曲線呈現三個時段，其特性有：(1)晚上10:30至隔日早上07:30為第一時段，此時段空調負載較低，約為設計容量的10%到20%。 (2)早上07:30到下午16:30為第二時段，所需負載約為設計容量的30%到50%。 (3)第三時段為下午16:30到晚上22:30，所需負載約為設計容量的50%到100%。造成第三時段高負載原因為國家音樂廳的表演節目，絕大部分在夜間或假日演出，造成該時段2千多位觀眾大量湧入，因而使負載劇增，加上舞台燈光的高熱量及演出人員的熱負荷，使第3段呈現特殊的高尖峰負荷。本文以國家級音樂廳中央空調系統為對象，進行儲冰空調系統應用於國家級音樂廳建築之可行性評估，用以轉移尖峰負載。可行性評估以回收年限作為指標，針對儲冰規劃、控制策略、以及運轉成本等三層面，進行探討。儲冰規劃包含全量儲存及分量儲存，分量儲存又分多種不同儲冰比例探討；控制策略則考量主機優先及儲冰優先兩種策略；運轉成本則依三種時間電價進行分析。研究結果發現，分量儲存比全量儲存回收效益高；儲冰優先策略優於主機優先策略；運轉成本以複合式電價之回收年限為最佳，約為6.74年。綜合評估以Case-4b為最佳案例，約每年可節省194.7萬元。本文研究成果，對於未來與國家級音樂廳類似的表演場所，可做為儲冰空調系統規劃的參考。

According to the running data of National Concert Hall in 2009 and the operational characteristic of National Concert Hall, it was found that load characteristic curve of air-conditioning system presents three time periods. (1)The first time period is from 22:00pm and 7:30am in the following day. The loading in this time period is the lowest and is estimated to be 10% to 20% out of design load. (2)The second period is from 7:30am in the morning to 16:30pm in the afternoon. The loading in this period is approximately 30% to 50% out of design load. (3)The third period is from 16:30pm in the afternoon to 22:30pm at night. The loading is about 50% to 100% out of design load. The reason of high loading in third time period is that the performance in National Concert Hall is hold in the night or on the weekend which makes 2,000 audiences come in simultaneously. In addition to the large amount of heat from those stage lights and perfumers, the third time period presents the extreme peak load. The purpose of this study was to evaluate, the feasiblity of ice-storage air-conditioning system in National Concert Hall. This evaluation was based on ice-storage plan, control strategy, and operation cost etc. First, ice-storage plan includes full storage, and partial storage which was analyzed for diverse storage percentages. Second, control strategy was examined for chiller-priority and storage-priority alternatives. Also the energy consumption with diverse storage percentages was calculated and the operation cost with various Time-of-Use rates was analyzed. The system efficiency of partial storage is higher than that of full storage. The optimum DPB (discounted payback period) under the operation cost for the Time-of-Use for Combined Sections rate is about 6.74 yrs. Based on the Case-4b results, the use of ice-storage air-conditioning system could save up to $1,947,000 NTD per year. Furthermore, in future National Concert Hall or similar place could use the finding of this study as a reference for ice-storage air-conditioning system design.
