Counter Flow Cooling Tower with Opposite Spray Water & Air Inlet Flows

Hot process fluid enters the coil (or tube bundle) from the water intake, and the spray system and fan system are started at the same time. The heat of process fluid undertakes heat transfer via tube walls and is transferred to the spray water running through the outer surface of the tube. The process water becomes cool and then flows out from the water outlet for internal circuit. Driven by the fan, the air outside the unit enters from the air intake, in the opposite direction of water flow, and moves upward through the coil. A small amount of water evaporates and flows through the drift eliminator, collecting the excess moisture into the water tank. Meanwhile, the hot and humid air is dispatched into the atmosphere from the top of the tower. The rest of the water falls into the water tank at the bottom, recycles to the spray system via the water pump, and then returns to the tube bundle.
