FABRICATION OF AIR COOLER USING COPPER TUBES AND REFRIGERANT GAS

The growing demand for affordable and eco-friendly cooling systems has encouraged the development of hybridtechnologies. This study presents the design and fabrication of an air cooler that integrates vapor compressionrefrigeration (VCR) principles with copper tubing and refrigerant gas (R134a). The system enhances heatexchange using high-thermal-conductivity copper coils and optimizes air cooling with a fan-assistedmechanism. Results indicate improved cooling efficiency and reduced electricity consumption, making it aviable alternative to traditional air conditioning, especially in resource-constrained settings.
