Cooling Tower Test Rig – Description A cooling tower test rig is a laboratory-scale setup designed to study the performance of a cooling tower, heat rejection process, and mass transfer between air and water. It helps students and researchers understand evaporative cooling principles, effectiveness of cooling towers, and key operating parameters. ⸻ Main Components: 1. Cooling Tower Unit • A vertical column (generally acrylic or glass for visibility) representing a miniature cooling tower. • Filled with packing material (plastic or wooden) to increase contact surface area between air and water. 2. Water Circulation System • Overhead water tank/reservoir to supply hot water. • Centrifugal pump for water circulation through the system. • Spray nozzles/distributors at the top to spray hot water over the packing. • Water sump or collection tank at the bottom. 3. Air Circulation System • Blower/fan to force air in counter-flow (bottom to top) or cross-flow with respect to water. • Air passes through the tower and facilitates evaporative cooling. 4. Heating Arrangement • Electrical heater provided in the sump to raise water temperature to the desired level before circulation. 5. Measuring Instruments • Thermometers/temperature sensors: • Hot water inlet temperature • Cold water outlet temperature • Dry bulb & wet bulb temperatures of inlet/outlet air • Rotameter/flow meter for measuring water flow rate. • Manometer/Anemometer for air velocity measurement. Working Principle: • Hot water is pumped to the top of the tower and sprayed over the packing. • Air is drawn in (usually by a blower) and flows upward in counter-current to water. • A small portion of water evaporates, removing latent heat, which reduces the temperature of the remaining water. • The cooled water collects in the sump and can be recirculated. • Performance is studied by comparing cooling range, approach, effectiveness, and evaporation loss. ⸻ Experimental Capabilities: • To study the cooling characteristics of a cooling tower. • To determine effectiveness of cooling tower. • To calculate range (difference between inlet and outlet water temp.). • To calculate approach (difference between outlet water temp. & WBT of air). • To measure evaporation losses and heat rejected. • To understand influence of water and air flow rates on cooling performance.
