The cooling characteristics of an air-cooled condenser with its surface fully covered with thin water film are investigated and compared with that of an air- cooled condenser with usual dry surface. By applying the evaporative cooling, the cooling performance of the condenser is shown to improve enormously. When the outdoor air is 35℃ and 40% in relative humidity, the condensing temperature of the refrigerant is decreased by 20℃. Even when the incoming air is fully saturated with water vapor, the evaporation from the wet surface occurs to cause a decrease in the condensing temperature by 10℃. The main reason for this improvement is assessed as the addition of an efficient cooling mechanism which is the water evaporation resulting in latent heat absorption. 대한설비공학회 증발냉각에 의한 공랭 응축기의 성능향상 가능성에 관한 연구 Cooling Enhancement Potential of an Air-Cooled Condenser by Evaporative Cooling Article 2 설비공학 논문집, v.16, no.3, pp.203 - 210 설비공학 논문집 16 3 203 210 kci ART001101236 Evaporative cooling(증발냉각) Air-cooled condenser(공랭식 응축기) Cooling performance(냉각성능) Wet surface(습표면) Evaporative cooling(증발냉각) Air-cooled condenser(공랭식 응축기) Cooling performance(냉각성능) Wet surface(습표면)
