“Development and Acceptability of Innovative R410A Refrigerant Recovery Kit”

This project development study aimed to design, construct, and evaluate an R410A Recovery Kit for application in the refrigeration and air conditioning industry. The device integrates a refrigerant recovery machine and a pressure washer, providing technicians with essential tools for efficient system servicing and maintenance. Evaluation was conducted with HVACR faculty members who assessed the kit’s design and functionality using standardized criteria. Findings revealed a high level of acceptability, with an overall mean rating of 4.48, indicating strong endorsement. Portability (mean = 4.57), use of durable locally sourced materials, and clear labeling of component parts were identified as key strengths, contributing to ease of operation and reduced errors. The results confirm that the kit is a practical, cost-effective, and user-friendly alternative to imported equipment. The study concludes that the R410A Recovery Kit meets both technical and user expectations, offering a valuable contribution to sustainable refrigerant management and technical training. Recommendations include integrating digital monitoring features, enhancing ergonomics, and conducting further development studies to refine safety and functionality.
