Basic Water Cooling Tower
The Basic Water Cooling Tower is completely self-contained and includes both the simulated heating load and the circulating pump. It has much the same configuration as a full size force drought cooling tower, has the same characteristics and stabilizes quickly.
In this unit a fan is placed at the base of the tower to drive air upwards through the packing. Natural buoyancy assists the fan and helps dissipate the humid air from the top of the tower.
The packing in the cooling tower breaks the water into thin films or droplets which present a large surface area to the air stream and thereby assist the cooling process. The water is cooled largely by evaporation and, to a small extent, by direct contact cooling. Due to the evaporation of some of the water into the air stream, a continuous supply of fresh water must be added to the system. This ‘make-up’ is normally less than 5% of the cooling water flow rate. A float valve is provided to allow accurate measurement of ‘make-up’. When the cooled water falls to the load tank it is reheated before circulation.
