Abstract — This paper presents detailed methodology of a Induced draft cooling tower of counter flow type in which its efficiency, effectiveness, char-acteristics are calculated. Due to the available product capacities, air-cooled chillers are typically used in applications that require 300 tons of cooling or less. Passivation is a process whereby materials are made corrosion-resistant. There is an elementary equation from basic thermodynamics that states that the rate of heat transfer (Q) equals the mass flow rate (M) times a Constant (the specific heat of water) times the Delta T (fluid temp out minus fluid temp in): Q = M x C x Delta T. Minor additional cooling is provided by the air because of its temperature increase. Q over t is the rate of heat transfer - the amount of heat transferred per second, measured in Joules per second, or Watts.
