The modern era of smart industries has increased heat generation and energy consumption tremendously, creating a huge demand for intelligent industrial cooling and energy optimization. But the existing coolers cannot perform adaptive prediction, intelligent monitoring and overheating prevention in dynamic industrial environment. To overcome these limitations, a Hybrid Neuro-Fuzzy Smart Cooling System (HNF-SCS) using IoT is introduced in this research. The proposed framework is a combination of Artificial Neural Networks (ANN), Fuzzy Logic Controller (FLC) and Proportional-Integral-Derivative (PID) based cooling control and sensor monitoring using IoT for intelligent thermal management. First, the industrial sensors gather real-time parameters like temperature, humidity, machine loading and power consumption. Future thermal conditions are predicted by the ANN model and overheating risk is identified by thermal analysis. The fuzzy logic controller calculates the needed cooling level based on the forecasted state and the PID controller controls the HVAC systems, fans and cooling pumps to keep the temperature stable without wasting too much power. Experimental results showed that the proposed HNF-SCS gave the maximum heat reduction rate of 98.85%, consumed 48.55 kWh and had small prediction errors. The proposed framework thus effectively enhanced the energy optimization, thermal stability, cooling efficiency and industrial safety in the smart industry.
