摘要
空調系統節能的方法有許多種，外氣空調節能對於尖峰用電的改善無明顯的效果，因此並不受到重視。但站在能源與使用者付費的觀點而言，外氣空調著實是一個投資少、獲利多、回收快的空調節能方式。尤其以全年，24小時使用空調之場所為甚；因此外氣節能空調系統之應用與研究應予以重視。 外氣空調之所以未受重視，除了未能有效解決國內目前電力之夏季尖峰負載的因素外，尚缺乏一套考慮空調機組耗電量的外氣空調節能控制技術。 針對此原因，本研究乃以現有的全氣式定風量冰水式空調系統，提出四個外氣空調模式，對這四種外氣空調模式提出各自的物理模型和外氣空調策略，撰寫電腦程式相互比較何者省能並且討論外氣空調策略省能的原因，以期望能提供改善現有的外氣空調策略，增加外氣空調省能的效果並可得到室內恆溫、恆濕控制。經過電腦的演算結果，獲得下列結論： (1) 使用水加濕器於外氣空調的過程，確實有助於節省空調耗電量。 (2) 當外氣焓值介於室內焓值與供風焓值之間，使用冷卻減濕盤管與再熱器一起動作時，混合風的比例不一定以焓值控制器的選擇為最好。

It is many way that energy-saving of Air condition system. Because energy-saving of free cooling can not improve crest of electricity supply, so free cooling isn’t appreciated. If we consider energy-saving and charge cost for user, energy-saving of Air condition system of free cooling is a minimum investment、much profit and fast return ,especially it is used during 24-hours day. To appreciate energy-saving of free cooling is very important. It isn’t appreciated that free cooling doesn’t consider air condition system to consume power. The investigation research that constant air-volume chiller water system and address four free cooling models. Four models introduce physics model and device of free coolig for themselves. Using computer program compare each other to discuss reason of energy-saving. We hope that this investigation can improve device of free cooling、increase energy-saving effect and get constant interior temperature and humidity. By simulative computer program we get conclusion by follows: (1) To use water sprayer is helpful for energy-saving effect during free cooling process. (2) When extraventricular enthalpy is between enthalpy of indoor and enthalpy of blast, it is not very good that enthalpy controller select mix-air proportion.
