Cooling tower

A cooling tower is a heat rejection device that rejects waste heat to the atmosphere through the cooling of a water stream to a lower temperature. A cooling tower is a specialized heat exchanger in which air and water are brought into direct contact with each other in order to reduce the water’s temperature. As this occurs, a small volume of water is evaporate reducing the temperature of the water being circulated through the tower.

In a counter-flow cooling tower air travels upward through the fill or tube bundles, opposite to the downward motion of the water. In a cross-flow cooling tower air moves horizontally through the fill as the water moves downward. Cooling towers are also characterized by the means by which air is moved.

How a Cooling Tower Works Warm water from industrial equipment, commercial ac system or any other heat source enters the tower and spreads evenly at the top. As the water flows down the tower , the equipment fill spreads it over a large area to increase the water-air contact, thus enhancing heat transfer via evaporation. Evaporative cooling towers are the most energy efficient means of cooling water. Hot process water or condenser water from a chiller enters the distribution system at the top of the cooling tower and falls by gravity in counter-flow to the air being drawn or forced through the cooling tower by the fan. The make-up water source is used to refill water lost to evaporation.

The cooling system may consist of a cooling tower , evaporative condenser or other cooling element, the re-circulating pipe work, the heat exchanger, pumps and ancillary items such as supply tanks. Open or wet cooling towers are the most efficient way to reject heat from the cooling system because the water evaporates to carry the heat away. Wet bulb temperature of a cooling tower is measured by sling psychomotor. This open side faces the prevailing win thus catching it, and brings it down the tower into the heart of the building to maintain air flow, thus cooling the building interior.

It does not necessarily cool the air itself, but rather relies on the rate of airflow to provide a cooling effect. A cooling tower is a device which is used to extract excess heat from the process water stream and rejects this excess heat to the atmosphere. In industry a large amount of heat is generated continuously which is required in various processes. A cooling tower is designed to remove heat from a building or facility by spraying water down through the tower to exchange heat into the inside of the building. Air comes in from the sides of the tower and passes through the falling water.

As the air passes through the water, heat is exchanged and some of the water evaporates. It is located beneath the water distribution layer and above the sump of the cooling tower. Removal of the cooling tower pack, where this can be done relatively easily and reinstated safely without damage, will inform the inspection and assessment and aid any potential cleaning but the.

They require specialized maintenance to ensure safe, efficient, and reliable operation, including an effective water treatment program. During the cooling tower working process, small volumes of water evaporate, lowering the temperature of the water that’s being circulated throughout the cooling tower. The Cooling Tower receives warm water from the chiller at a temperature, for example, of 32°C (8°F).

This water is known as the condenser water because it picks up it’s heat in the “condenser” of the chiller. The address of the premises where the notifiable device is. The number of notifiable devices at the premises referred to.

These large towers can be in excess of 2m high and while a number of elements will impact efficiency, the general process is the same.

Fundamentally, cooling towers are an organic heat exchanger. Warm or hot water from a process is cooled by passing it through the tower and then back out into the process. A cooling tower enables the water to meet the air so that some of the water evaporates, lowering the overall water temperature. Because there is no direct contact between the working fluid and the ambient air, there is no water loss in this system.

What is a cooling tower ? Dry cooling towers have two basic types: direct and indirect systems. Put simply, a cooling tower is designed to remove heat from water, hence the name. Waste heat that is generated from buildings or production processes is extracted by a local cooling system. That heat is then transported and finally ejected into the atmosphere once it has been cooled by the tower.

Cooling Towers for Refrigeration 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. The use of a cooling tower is the most common way of extracting waste heat in CPI operations, and water is the most commonly used coolant to remove waste heat in the majority of such operations. Our experienced team of cooling tower maintenance and repair technicians are skilled at inspecting, repairing and renewing both factory-assembled and field-erected cooling towers to restore thermal performance, improve energy efficiency and extend service life.

Gravity systems, employed on BAC’s crossflow cooling towers, feature hot water basins mounted on top of the tower above the fill. A series of spray nozzles in each hot water basin distribute the water evenly over the fill.
