COOLING TOWER INTRODUCTION Cooling is a process of transfer of thermal energy via thermal radiation, heat conduction or convection. The cooling process is an unavoidable phenomenon in the world which starts from the hydrologic cycle and extends up to various other processes. Cooling is done through various processes and with different components. Water is used as general transfer medium …

Warm water from the heat source is pumped to the water distribution system at the top of the tower. The water is distributed over the wet deck fill by means of large orifice nozzles. Simultaneously, air is forced through the air inlet louvers at the base of the tower and travels upward through the wet deck fill opposite the water flow. A small portion of the water is evaporated, which removes

The warm moist air is drawn to the top of the cooling tower by the fan and discharged to the atmosphere. The cooled water drains to the basin at the bottom of the tower and is returned to the heat source. The vertical air discharge of the AT design and the distance between the discharge air and fresh air intakes reduces the chance of air recirculation, since the warm humid air is directed up
maintaining a water efficient cooling tower. The overall purpose of a water treatment report is to provide a ‘snapshot’ of the cooling tower operation and the effectiveness of the current water treatment program. To define the outcomes of a water treatment program, suitable key performance indicators (KPI’s) must be in place within the water treatment contract including tracking the
treatment. 2. Principles for Operation Analysis. A cooling tower cools water by contacting it with the air and evaporating some of the water. One or more axial or centrifugal fans move the oair vertically up or horizontally through the tower. Spraying the water through nozzles or splashing the water down the tower from one baffle to another provides a large surface area of water. The
