Water cooling Tower Unit (SMT-RAC-06)
This apparatus is designed to demonstrate the principles of evaporative cooling in a water cooling tower, allowing students to study heat and mass transfer as warm water is cooled by direct contact with an upward flow of air. It enables the investigation of key factors such as air velocity, water flow rate, and cooling load on the towers efficiency and operational range.
The unit features a transparent cooling column with an interchangeable wet deck surface, a variable-speed fan for air flow control, and an adjustable pump for water circulation. The water is heated by a multi-stage electric heater, and the system is equipped with sensors to measure temperature, humidity, differential pressure, and flow rates. All parameters are monitored and controlled via a touchscreen LCD interface and data acquisition software, which logs data for analysis on a connected computer.
Its primary applications are in mechanical and chemical engineering education for teaching thermal system design and HVAC principles. The key benefit is the hands-on analysis of cooling tower performance, enabling students to visualize the process, quantify the effects of different variables on efficiency, and understand the role of evaporation in industrial heat rejection systems.
