#Cooling tower design calculation xls pdf

It is possible, but they are not used because their cost is more expensive than alternative cooling methods. Water of high alkalinity, hardness, and conductivity can operate between 1.5-2.5 COC. The thermal capability of a cooling tower used for air condition- ing is often expressed in nominal cooling tower tons. Generally speaking, you can also estimate that for every 10вЏ (or 5.5вЊ) of water cooling in the tower, there will be 1 percent of water mass lost due to evaporation. Obtain water analyses for the recirculating cooling water and makeup. Coil Cooling Towers The HVAC Quick Load for Android is the one and only rule-of-thumb HVAC heating and cooling load application for Google Android mobile devices.

Features of PDF to XLS Converter: 1.Working platforms: Windows 2000 and later systems, both 32bit and 64bit systems. For example, sewer tap fees for a new plant of $100,000 were reduced to $10,000 simply by increasing cooling tower cycles from 3 to 6, cutting the blowdown amount in half. If steam is coming in, or doing any kind of heating, you have to take the BTUs out at some point. Influence of ГўВЂВ¦ Consideration of By-Pass Wall Water 10. Evaporation loss = 0.00085 x 10 000 x (100-85) = 127.5 gpm Drift loss = 0.02% x 10 000 = 2 gpm Blowdown = /(5-1) = 29.87 gpm Cooling tower makeup water = 127.5 + 2 +29.87 = 159.37 gpm Reference: PerryГўВЂВ™s Chemical EngineersГўВЂВ™ Handbook As the water flows through the cooling tower, it is exposed to air, which is being pulled through the tower by the electric motor-driven fan. If you read this book carefully, you can make any cooling tower design programs by yourself. Required area of cooling tower is quantity of water circulated divided by water concentration = 1000/2.8 = 357.14 ft 2. ГўВЂВ¦ When hot water temperature is 102 o F and cold water temperature is 78 o F, we get water concentration at around 2.8 gal/ (min.ft 2).
