Cooling Tower Teaching Equipment

Cooling Tower is designed for practical teaching and demonstration of the operating principles and performance of a wet cooling tower with forced ventilation. The system reproduces the main processes found in an industrial cooling system served by a forced-draught cooling tower.

The unit incorporates a process load, circulating pump, cooling column, water distribution system, volume control system and fan. Water is circulated through the cooling column and distributed using a nozzle as an atomizer, while a radial fan provides forced ventilation. Interchangeable cooling columns with different wet deck surfaces can be used for comparative studies.

A three-stage heater with thermostat is provided for controlled water heating. A throttle valve allows adjustment of the air flow, while a demister unit at the cooling column outlet minimizes water loss. An additional water tank compensates for evaporation and other water losses.

The system allows measurement of air and circulating water flow rates, temperatures and humidity. Students can investigate evaporation rates under varying load and flow conditions, observe water flow patterns and distribution, determine end-state conditions and develop energy balances using the steady-flow equation. Performance can be investigated over a range of process cooling loads and inlet temperatures.
