Abstract

The increasing global demand for energy and the urgent need to reduce greenhouse gas emissions necessitate innovative solutions in energy-intensive sectors such as air conditioning. This research presents the development of a fuzzy logic-based smart control system for hybrid air conditioning systems utilizing Phase Change Materials (PCMs) to enhance energy efficiency and thermal comfort. The proposed system integrates an ESP32 Dev Kit as the central controller and DS18B20 sensors for accurate temperature monitoring, offering a cost-effective and versatile solution for dynamic thermal management. The fuzzy logic controller (FLC) optimizes system performance by regulating compressor operations, PCM utilization, and thermal balance in response to environmental and indoor conditions. Simulation results demonstrate the system's ability to efficiently cool a space from 29°C to 22°C in approximately 165 minutes and maintain this temperature for ±47 minutes through PCM discharge. The combined fuzzy logic design achieves a 97% reliability rate, ensuring precise temperature control while adapting to complex input variations. While the FLC-enabled system exhibits a marginal increase in energy consumption (4.21 kWh over 7 hours compared to 3.81 kWh for non-FLC systems), it significantly improves thermal regulation and extends PCM usability. This trade-off underscores the system's ability to balance energy efficiency with enhanced user comfort, highlighting its potential for reducing HVAC-related energy consumption. This study provides a foundation for the integration of fuzzy logic and PCM technologies in HVAC systems, offering significant implications for industrial applications and future research in intelligent control strategies for sustainable energy management.
