Spray Cooling Tower Design

Paharpur provides spiral spray nozzles made of inert polypropylene plastic to ensure hot water distribution is uniform over the fill pack.

Spray cooling tower 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. 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 hyperboloid shape also aids in accelerating the upward convective air flow improving cooling efficiency. 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.

The required cooling tower design and size will be a function of following values. C approach to wet bulb temperature d mass flowrate of water circulation rate. 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.

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. Thus a significant proportion of the condensed vapour is evaporated in the cooling system. Most of the cooling occurs by evaporation and only a small proportion is by sensible heat transfer.
