Get Evapco Ict & At-d Cooling Towers

With respect to drawing air through the tower, there are three types of cooling towers: Natural draft Utilizes buoyancy via a tall chimney. Warm, moist air naturally rises due to the density differential compared to the dry, cooler outside air. Warm moist air is less dense than drier air at the same pressure.

Chiller Refrigeration Tons Some commercial and industrial refrigeration systems are rated in Tons of Refrigeration (TR, tons). A ton is the amount of heat removed by an air conditioning system that would melt 1 ton (2000 lbs.) of ice in 24 hours. The heat required to melt 1 lb of ice at 32 oF to water is 144 Btu.

Crossflow towers will serve better for maintenance access, variable flow, and cold weather operation. Counterflow towers may serve better in tight spaces under 750 tons, or in spaces where lower operating weight is required.

Design Criteria of a Cooling Tower: Approach. The size of a cooling tower depends on the flow, water inlet and outlet temperatures and the design wet bulb temperature. The difference between the water outlet and wet bulb temperature is called the approach. The smaller the approach, the larger the size of the tower.

Natural Draft cooling towers use the design and shape of the tower itself to move up the air naturally using fans. ... Mechanical Draft towers tend to use a fan to force the air.

Mechanical draft cooling tower. Atmospheric cooling tower. Hybrid draft cooling tower. Air flow-characterised cooling tower. Construction-characterised cooling tower. Shape characterized cooling tower. Cooling tower based on method of heat transfer.

Water-cooled chillers are normally more energy efficient than air-cooled chillers due to heat rejection to tower water at or near wet-bulb temperatures. Air-cooled chillers must reject heat at the higher dry-bulb temperature, and thus have a lower average reverse-Carnot cycle effectiveness.
