김철호(Chul Ho Kim),김원일(Won Il Kim),최재영(Jea Young Choi),김재철(Jae Choul Kim),김민선(Min Sun Kim) 대한설비공학회 2013 대한설비공학회 학술발표대회논문집 Vol.2013 No.11
A new concept of an Eco-friendly desalination method is introduced in this study. The main idea of the desalination method of seawater is the condensation of the vaporized seawater by solar heat energy on the surface of seashore. The wind turbine blade plays a role of heat exchanger condensing the vaporized water in the air. Fig. 1 shows the details of the operating concept of the Eco-friendly desalination system with the wind power generation turbine. In this analytical study, the availability of the proposed desalination system was studied. First, an analytical condensation theory of the vaporized water in air was arranged and the parametric study was conducted to estimate the amount of freshwater produced from the system with the change of the temperature difference between the humid air and turbine blade, and the relative humidity in air, and wind speed. From the analytical calculation, 44,229(ton/year) of freshwater was produced at the vertical-type wind turbine (Diameter=4m, Height=3m) as the relative humidity is 80%, the temperature difference between the impeller blade and the humid air is 35℃ and the wind speed is10m/s.

김철호,김원일,최재영,김재철,김민선,Kim, Chul-Ho,Kim, Won-Il,Choi, Jea-Young,Kim, Jae-Choul,Kim, Min-Sun 대한기계학회 2014 대한기계학회 논문집. Transactions of the KSME. C, 산업기술과 혁신 Vol.2 No.1
본 연구에서는 태양열에 의해 증발된 해수면에서의 수증기를 응축의 원리를 이용하여 담수의 생산이 가능한 친환경 담수장치(Eco-friendly Desalination System)를 고안하고, 가능성을 판단하는데 연구의 목적을 두고 있다. 응축 열전달 공식을 이용하여 습공기의 물성변화에 따른 연간 응축수 생산량을 예측하였으며, 항온항습챔버의 실험을 통해 실제 습공기조건 변화에 따른 응축량을 측정하였다. 습공기의 이론 응축률과 실험을 통해 측정한 실제 응축률의 오차율을 산출하였으며, 오차의 원인을 분석하고 응축률 보정계수인 응축계수와 점성계수를 구하여 보정된 이론 응축률 공식에 도출하였다. 보정된 응축률 식을 이용하여 설계된 규모의 풍력터빈연간 생산 가능한 담수량을 산출한 결과 최대 연간 약 2,927톤 정도의 담수를 생산할 수 있다는 사실을 알 수 있었다.
