A Review on Cooling Tower Efficiency Enhancement & IOT Integration

Mechanical Engineering

Industrial cooling towers are widely employed to reject excess heat from processes, yet their performance often deteriorates due to ineffective air circulation and limited real-time monitoring. This project focuses on the design and development of a prototype cooling tower with enhanced efficiency through the integration of an ESP32-based control system and IoT connectivity. The physical model consists of a compact tower frame with a water distribution system, collection basin, and a top-mounted exhaust fan. A waterproof digital temperature sensor (DS18B20) is installed within the tower to monitor the air–water interaction zone. The ESP32 microcontroller continuously records temperature data and, when a rise beyond a defined threshold is detected, it automatically activates the exhaust fan to accelerate convective heat removal. To ensure user awareness and remote monitoring, the ESP32 simultaneously triggers a notification to a mobile device via an IoT platform whenever the fan is switched on. This integration not only improves cooling effectiveness by maintaining stable tower temperatures but also demonstrates the potential for predictive maintenance, reduced downtime, and optimized energy usage in industrial cooling operations. The prototype validates the combined benefits of traditional thermo fluid design with modern automation and IoT, establishing a pathway toward smart, efficient, and connected industrial cooling solutions.
