隨著全球商業化與工業化的發展,能源的消耗量不斷的增加,而地球又面臨消耗大量能源產生大量二氧化碳,以致嚴重地球暖化之效應。且我國大部分的能源需經由國外進口,更應重視節約能源。所以節約能源已成了永續經營之必要條件,也因應聯合國「氣候變化綱要公約」之必要對策。相關政府機構已推行節能減碳的具體措施,但是台灣地處亞熱帶相對地理氣候條件下,整年度空調耗能比重也相較來的高,因此本研究目的為藉由eQUEST模擬醫院類空調耗能;找出相對節能之空調系統,台灣地區醫療類建築之節能應用空調系統耗能分析;選定變風量節能系統、變水量節能系統及變冷媒節能系統分析比較,醫療類型建築應用於亞熱帶台灣氣候環境的耗能特性。 VRV 系統由於直接以改變冷媒流量之方式,縮短了原先由冷媒至冰水再轉換至空氣側之傳熱過程,形同取代了VWV 加上VAV 之效果。對於400床以下冷房需求之中小型醫療建築物而言,獲得極顯著的節能效果;整體建築總耗能模擬結果得知VRV系統相對比VAV系統節省耗能7.79%;比VWV系統節省耗能6.79%
With global commercialization and industrialized development, the energy consumption is increase continuous every year. Most energy of our country are import from others and we should pay more attention to the energy issue. Taiwan locate in subtropical area and annual air conditioner power consumption is high. This research simulate the energy consumption of hospital with eQUEST and comparing three kinds of systems, finally choose the best proposal. VRV system shorten the heat transfer process of refrigerant to water and water to air-side by vary the flow rate of refrigerant . The result is the same of VWV with VAV system and we get significant energy-saving effect for medium-sized medical buildings.Compare three systems with the total power consumption, VRV system saving 7.79% electricity than VAV and 6.79% than VWV system
