Cooling tower basic knowledge.

What is a (wet, atmospheric) cooling tower?

A cooling tower is a heat rejection device, which extracts waste heat to the atmosphere though the cooling of a water

stream to a lower temperature. The type of heat rejection in a cooling tower is termed “evaporative” in that it allows a small

portion of the water being cooled to evaporate into a moving air stream to provide signifi cant cooling to the rest of that

water stream. The heat from the water stream transferred to the air stream raises the air’s temperature and its relative

humidity to 100%, and this air is discharged to the atmosphere. Evaporative heat rejection devices such as cooling towers

are commonly used to provide signifi cantly lower water temperatures than achievable with “air cooled” or “dry” heat rejection

devices, like the radiator in a car, thereby achieving more cost-effective and energy effi cient operation of systems in

need of cooling. Think of the times you’ve seen something hot be rapidly cooled by putting water on it, which evaporates,

cooling rapidly, such as an overheated car radiator. The cooling potential of a wet surface is much better than a dry one.

    What is a (wet, atmospheric) cooling tower?什麼是(濕的,氣壓的)冷卻塔?

    A cooling tower is a heat rejection device, which extracts waste heat to the atmosphere though the cooling of a water stream to a lower temperature. 冷卻塔是熱的排除設備,它分離出廢熱再排到大氣,把水蒸氣冷卻到較低的溫度。 The type of heat rejection in a cooling tower is termed “evaporative” in that it allows a small portion of the water being cooled to evaporate into a moving air stream to provide significant cooling to the rest of that water stream. 這種在冷卻塔的熱排出方式被撐為” 蒸發",它使一小部份被冷卻的水蒸發成為移動的氣流來提供其餘水蒸氣重要的冷卻。 The heat from the water stream transferred to the air stream raises the air’s temperature and its relative humidity to 100%, and this air is discharged to the atmosphere. 來自於水蒸氣的熱量轉移到氣流升高空氣的溫度和提高濕度到100%, 並且此空氣被排出到大氣中。 Evaporative heat rejection devices such as cooling towers

    are commonly used to provide significantly lower water temperatures than achievable with “air cooled” or “dry” heat rejection

    devices, like the radiator in a car, thereby achieving more cost-effective and energy efficient operation of systems in

    need of cooling. 蒸發熱排除設備, 如冷卻塔,常用於提供比”氣冷的”或”乾式的”熱排除設備所能達到的更低水溫,像在汽車內的散熱器,因此實現了在需要冷卻時,更具成本效益的和節能的系統運轉。 Think of the times you’ve seen something hot be rapidly cooled by putting water on it, which evaporates, cooling rapidly, such as an overheated car radiator. The cooling potential of a wet surface is much better than a dry one.想想看你見過熱的東西被澆上水而被快速冷卻的次數,它蒸發、快速冷卻,例如過熱的汽車散熱器。潮濕表面的冷卻潛力遠比乾式的要好。
