Spray Cooling Tower Design

Cooling tower the water is cooled by contact with cooler ambient air either in conventional cooling towers or in spray ponds.

Spray cooling tower design.

B web bulb temperature. The hyperboloid shape also aids in accelerating the upward convective air flow improving cooling efficiency. Nfpa 214 water cooling towers provides guidance on the provision and design of fire protection systems and protective measures for cooling towers constructed of combustible materials. These nozzles are high temperature resistant and have a non clogging design.

C approach to wet bulb temperature d mass flowrate of water circulation rate. Paharpur provides spiral spray nozzles made of inert polypropylene plastic to ensure hot water distribution is uniform over the fill pack. Uniform distribution facilitates uniform cooling uniform distribution of water is crucial to maintain cooling tower efficiency. 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.

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. 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. Most of the cooling occurs by evaporation and only a small proportion is by sensible heat transfer.
