Spray Cooling Tower Design

The required cooling tower design and size will be a function of following values.

Spray cooling tower design.

B web bulb temperature. Hyperboloid sometimes incorrectly known as hyperbolic cooling towers have become the design standard for all natural draft cooling towers because of their structural strength and minimum usage of material. These nozzles are high temperature resistant and have a non clogging design. The system has been designed so that the condenser water leaving the cooling tower and re entering the chiller condenser must be around 27 c 80 6 f in order to be able to pickup enough heat on it s next cycle.

The condenser water leaves the condenser of the chiller at around 32 c 89 6 f and the pump sends this up to the cooling tower. Uniform distribution facilitates uniform cooling uniform distribution of water is crucial to maintain cooling tower efficiency. Most of the cooling occurs by evaporation and only a small proportion is by sensible heat transfer. Paharpur provides spiral spray nozzles made of inert polypropylene plastic to ensure hot water distribution is uniform over the fill pack.

Specific protection for the interior of the cooling tower combustible materials but also for the probable source of ignition e g motors should be made. Cooling tower the water is cooled by contact with cooler ambient air either in conventional cooling towers or in spray ponds. The hyperboloid shape also aids in accelerating the upward convective air flow improving cooling efficiency.
