Cooling tower pdf

The water exits the cooling tower and is sent back to the exchangers or to other units for further cooling. Typical closed loop cooling tower system is shown in Figure 7. A psychromehic analysis of the air passing through a cooling tower illustrates this effect (Figure 2). Air enters at the ambient condition Point A, absorbs heat and mass (moisture) from the water. The cooling tower must be adequately sized to reject this same amount of heat to the atmosphere.

Recirculation raises the effective WBT of the air entering the tower with corresponding increase in cold water temperature.

Cooling towers are used to reject heat through the natural process of evapora-tion. Proper material selection or additional water treatment is then needed to keep the cooling tower safe. Some theories are needed to be understood before an engineer start to sizing a cooling tower.

Drift eliminators are installed to prevent water entrained in the air from leaving the system. Cooling Tower Outlet) temperature is called Cooling Tower Range. The term “induced draft” denotes that air is drawn by fans through the flow of falling water and up and out of the cooling tower. The major concern during I study the cooling tower theory was how to computerize the cooling tower theory from the calculation of NTU to the cooling tower performance analysis. If you read this book carefully, you can make any cooling tower design programs by yourself.

Again, this will be a first issue releasing the actual engineering approach.

Here we explain in full detail how does a cooling tower work, cooling tower working principles with example text, pictures and diagrams. How much does a cooling tower evaporate? What is cooling tower treatment?

How does a nuclear cooling tower work? In urban settings where natural bodies of water are sometimes limite cooling towers were used to recycle cooling water pumped through steam engines to condense the steam exhaust back into water. Introduction An open circuit or evaporative cooling tower is a heat rejection device that rejects heat to the atmosphere by cooling a water stream to a lower temperature. Both types function as heat exchangers based on the counter flow principle. An important device used in any refrigeration or air conditioning system is a condenser.

A condenser is used in the high pressure side of a refrigeration or air conditioning system to convert the high-pressure vapour refrigerant from the compressor into liquid refrigerant. We are dedicated to designing and manufacturing the highest quality products for the evaporative cooling and industrial refrigeration markets around the globe. Since the cooling towers are based on the principles of evaporative cooling , the maximum cooling tower efficiency depends on the wet bulb temperature of the air. As this occurs, a small volume of water is evaporate reducing the temperature of the water being circulated through the tower.

Introduction A cooling tower is a heat rejection device which extracts waste heat to the atmosphere through the cooling of a water stream to a lower temperature. Maximize equipment life span. Ensure cooling tower operation complies with NYS DOH Legionella Regulations. The program is designed to: 1.
