This is not a problem with the vast majority of cooling towers in service today.Ĭooling towers come in four main types. In some older cooling towers, the access opening is under the water level of the basin which requires the basin to be drained before entry. Each cell has an access door or panel for entry into the basin. Each cell is independent and has its own fan, fill and basin. For each chiller served by the cooling tower, there is a “cell†in the tower. Other components are also used in cooling towers such as float valves, filters, strainers, etc., but these are the basics.Ī single cooling tower can be used to supply chilled water to one or several chillers. A basin to capture and store the cooled water.The fill to expose the water surface to the air stream.A fan to move outside air through the tower.Spray nozzles to distribute the water over the fill.A pump to bring the water to the top of the tower.Most of today’s cooling towers are made using the same basic components: The water, cooled by partial evaporation, then falls into a basin at the bottom and is circulated back to the chiller to start the process all over again. As the water drops through the fill, fresh air from outside the cooling tower is forced through the tower. The purpose of the fill is to expose as much of the water’s surface as possible. The warm water returning from the chillers is pumped to the top of the tower and distributed by spray nozzles over a medium known as “fillâ€. This article will concentrate on the air conditioning application of cooling towers.
They are also used in process industries to cool materials. This process would eventually evolve into the modern cooling tower.Ĭooling towers are primarily used to cool water in air conditioning systems. The 1930’s saw the introduction of evaporative coolers, known as “swampies†which operate on the same principle as the early mill cooling towers and could cool the air temperature by as much as 10 degrees on days with low relative humidity.
The fans were used to move the water cooled air into the mills making working conditions more pleasant in the summer months. The first ventilation fans were developed in the 1500’s and were later combined with the “wet mat†cooling process to create the first rudimentary “cooling towers†in the textile mills of New England in the 1800’s. The same technique was later used in the royal palaces of India. Wind blowing through the mats evaporated the water thereby cooling the air entering the building.
GOODWAY COOLING TOWER VACUUM WINDOWS
As early as the times of the ancient Egyptians, Romans and Greeks, wet fabric mats were hung in the windows and doorways of dwellings to cool the indoor environment. The concept of moving air across a water stream to produce a cooling effect did not originate with the first cooling tower. New Technology Enhances Cooling Tower Maintenance
