After the hot water at the entrance to the tower is cooled, she's going to die in the cold water basin. The cold water basin in the lower part of the body, under the fill. The pool can be designed to act as a collector for the supply of water to the cold water pipe or as a reservoir, while maintaining the water level in the tower. In systems with the help of drainage back to the storage tank located within the building, cold water does not collect in the towers of the basin. Instead pool directs the water falling from the fill to the return water pipe connection.
Cold water passes through the reverse pipeline to the tank by gravity. Since water does not collect in the basin of these systems, make-up water valve located in Stoke-back tank, so it can respond to the water level in the tank. As the level drops, float, or solenoid valve opens the valve, allowing municipal water to fill the tank. Stoke back tower strategies are used in applications, where the tower is open in cold weather months. Maintenance of the pools of stagnant water prevents the water from freezing in the pool at low load.
In systems where the cold water basin, also acts as a reservoir for water is allowed to rise to a certain level in the tower, when the system works.
No internal water tank, so that the tower pump gets cold water of the pool, and delivers it to the condenser. Make-up water valve located in the swimming pool to maintain the desired level.
Overflow pipe is placed in the pool cooling towers, to the swimming pool water from rising too high. The tube opening is placed at a height of diat-above the normal operating level in the basin. If a system fault or a rapid decrease in load leads level in cold water rises above the height of the overflow pipe, the excess water will direcdy to a drain. The overflow pipe prevents the operating weight of the tower from increasing beyond the design structu ral download it supports...
