臺灣博碩士論文加值系統

台灣屬於亞熱帶海洋型氣候，高溫高濕，為了滿足對熱舒適的需求，空調設備使用得相當普遍。但現行空調基於省能的考量，在使用時需將空間密閉，以減少冷源流失。如此造成廢氣在室內累積無法消散，而新鮮空氣亦逐漸耗盡，使得室內空氣品質漸趨惡化。不但影響工作效率，也大大影響我們的健康。欲改善換氣情形，且又減少對現有空調之影響，提出一換氣風扇系統與方法以改善室內空氣品質。
基於以上之考量，設計一空調換氣風扇系統。在不影響使用者原本使用空調的習慣之下，以較簡單且耗電量較小之風扇，適時引入室外空氣，促進室內換氣，滿足健康之需求，同時又不造成原有空調設備過大的負擔。系統可由使用者以手動調整方式或自動運轉的方式來調節室內之通風換氣量決定。根據室外空氣的可用條件，引入適當的外氣量做室內空氣的調節，並於低溫可用之外氣條件下，減少原有空調設備之輸出，在滿足熱舒適的情形下，又兼具省能的功能。

Taiwan is under subtropical oceanic climate with high temperature and high humidity. For the need of thermal comfort, the air conditioners are very popular here. When these air conditioners are running, the room is often tight for the reason of energy saving. And that reduces the natural ventilation to remove the stale air and replace it with a fresh supply. So, in many situations, we can feel the effect of poor indoor air quality (IAQ) because of the accumulated pollutants and the insufficient fresh air. The poor indoor air quality affects not only the emotion but also the occupant’s health. In order to promote the air exchange rate and consider less influence to nowadays air conditioners, a ventilation fan and the methods to improve the indoor air quality is suggested here.
We, therefore, design an air-conditional ventilation fan system that does not affect the habit of those using traditional air-conditioning. The system adopts simpler fans exhausting less energy to lead into outdoor air in the nick of time. So those fans can promote the indoor ventilation to achieve our healthy require and are not burdens to traditional air-conditioning. The amount of indoor ventilation can been adjusted by the “User Mode” or the “Auto Mode”. According to the condition of outdoor air, the outdoor is drew in to adjust indoor air. In addition, the energy is saved by leading into the serviceable outdoor cool air. Consequently, the ventilation fan system can both satisfy the demands of the thermal comfort and meet the function of saving energy.
