傳統空調設備為達空調目的，其所採用各式熱移轉之熱源設備，於熱傳過程中，必須移用大量能源以進行各式之熱交換，在移轉過程中，吸熱裝置主要功能在於將空調空間之熱負荷吸取，使空調空間獲得降溫的效果，排熱裝置則需將熱源設備中吸熱裝置所吸之熱以及輸入熱源設備，以促進系統（設備）的各種能源所移轉的熱排除。也就是空調廢熱的排放，此龐大的廢熱若以顯熱方式排放，往往造成建築物外部嚴重的熱汙染。
本論文係提出一種水濾式空氣淨化省能裝置之研發與應用，其利用水濾方式來達到淨化空氣及藉由水蒸發來獲得空氣中熱量移轉之功效。主要係將空氣先經由多孔可滲水性濾氣管排之水洗過濾，去除空氣中之雜質而產生淨化之空氣，同時將室內〈或作業空間〉所欲排除之空氣，經過可滲水性濾氣管排時，產生水蒸發吸熱作用，使空氣及水的溫度下降，再利用自然對流管排的降溫，藉以改善環境空氣品質並產生適度節能效果，另外在需加熱的場合，只須將空氣的進出路徑改變，即可獲致同樣的效果，乃為本創新裝置之特色所在。
本文主要介紹水濾式空氣淨化省能裝置之運轉原理、機組結構、理論分析、原型機組裝等主題，並於經國家認證合格實驗室，實際運轉測試建立基本資料。配合各地氣候資料進行數據分析，並以傳統熱源空調系統做為比較基準，從初設費用、運轉費用、能耗、空氣品質等進行比較分析。
由研究結果指出，水濾式空氣淨化省能裝置之初設費用僅需傳統熱源空調系統40%~70%左右，運轉費用僅需傳統系統20%~70%，在空氣品質方面，每天運轉10小時的系統有50%以上的運轉時間可採全外氣的模態運轉。每天運轉24小時的系統有70%以上的運轉時間可採全外氣的模態運轉。

Conventional air-conditioners use much energy to promote heat transfer in rejecting cooling load for air-conditioning purpose. The waste heat will cause environmental thermal pollution if it is rejected by sensible heat transfer mode. To improve this inevitable defect of traditional air-conditioner, an innovative package unit with high energy-efficiency as well as air cleaning features is presented in this study. The present air-conditioner can provide clean air by an outside air washer and takes the advantage of evaporative cooling to recover cold energy. The working principle is, first, the outside air is introduced into a permeable water array for washing to remove the contaminant. At the same time the exhaust air is conducted into an air shower to proceed evaporative cooling, lowering its temperature and readily for cold energy recovery by upper portion of a heat-pipe heat exchanger located downstream. The exhaust air stream is then heated and all rejected to outdoor, which will lower the potential of environmental thermal pollution. On the other hand, the clean outside air after washing passes the lower portion of the heat-pipe heat exchanger, lowering its temperature by the recovered cold energy. This air stream is then introduced to a water heat exchanger to further cool down and then the low temperature and clean air is supplied for ventilation. This innovative air-conditioner is expected to be very energy-efficient and able to improve great indoor air quality. It will be studied and rated experimentally in detail in the present study to validate its operation functions, energy-saving ability and economics.
The experiments of this innovative unit were performed in a certified standard laboratory as well as in application field. The test results show that, the initial cost and running cost comparing to the conventional one is about 40% to 70% and 20% to 70% respectively. Regarding the indoor air quality, there is about 50% running time suitable for utilizing 100% outside air for ventilation in the case of 10-hour operation per day, while there is 70% in the 24-hour operation case.
