摘要: | 本研究旨在設計一個低能屋,由建築設計、機構設計到內部節能設備設計,使建築整體性能達低耗能規格,主要設備包括熱泵、換氣機與水冷氣系統,並設有中央控制系統。熱泵主要用來除濕與產生熱水,本研究採用露點追蹤控制技術以降低耗電量。換氣機進行高效率換氣,以維持良好之室內空氣品質。室內水冷氣系統係以搭配室外水簾片冷卻系統進行夜間蓄冷,供白天低能屋冷房需求。本研究接著進行節能設備整合,即設計一中央監控系統,用來控制各個設備的運轉設定,使其耗能降低且盡可能達到室內環境的舒適度。再來監測整體運轉結果顯示並分析低能屋各設備性能,其中夜晚儲能系統每小時平均蓄冷量(散熱量)為696W,白天釋冷循環系統釋冷量每小時平均量為285W,在4.5坪空間下,熱泵可收集一~二人水氣量,即熱泵除濕量2.22L/day,換氣機可置換一人於低能屋所釋放的CO2量。七月份平均每日低能屋總空調用電量約為0.36 kWh/ m2,低能屋隔熱材總熱傳透率U約可達0.24 W/m2K,低於德國省能建築最低標準0.45 W/m2K與行政院綠建築標準屋頂1.2W/m2K;外牆3.5 W/m2K。 This study aimed to design a low-energy house. The overall performance of low-energy house reaches to low-power specifications by architectural design, institutional design and interior design of energy-saving equipment including heat pump, fresh air exchanger and water cooling system and a central control system. Heat pump combining dehumidifier is used to produce hot water and to capture water from air. Heat pump combining dehumidifier uses dew point tracking control technology to reduce power consumption. Fresh air exchanger ventilates house to maintain good indoor air quality. water cooling system is designed to store cold water at night time for the supply of cooling load at daytime. We design a central monitoring system to integrate energy-saving equipment. The central monitoring system controls the operation of various equipment settings to reduce energy consumption and reach comfort requirement. Again monitor the overall operation of the results and analysis of the equipment performance. Cooling capacity of water cooling system at night time is 696W per hour. Cooling capacity of water cooling system at day time is 285W per hour. Heat pump produces 2.22 Liter water per day. Fresh air exchanger can replace CO2 of one person in low-energy house. The averge power consumption of the equipments of low-energy house is 0.36 kWh/ m2 per day in July. The thermal Transmittance of low-energy house is about 0.24 W/m2K. |
