Development of Dual Evaporator Air Conditioning with Heating System Trainer

The high level of development in the automobile sector, particularly sophisticated technologies like automobile air conditioning (A/C) systems, necessitates frequent revision of learning materials and training. The present study addresses the long-overdue need and obsolescence of learning materials in Autotronics studies, in this instance, Heating Ventilation, and Air Conditioning (HVAC) systems. Inadequate modern diagnostic software, special equipment, and updated visual items restrict students' exposure to real-world applications and understanding of complex ideas. To bridge this gap, the present study is focused on the design, development, and evaluation of a Dual Evaporator Air Conditioning with Heating System Trainer. Using the ADDIE (Analysis, Design, Development, Implementation, Evaluation) instructional systems design model, this study aims to create a hands-on training unit that can easily replicate successful learning of contemporary HVAC systems in automotive applications. The prototype model entails necessary components of air vents, blend doors, blowers, heater cores, hoses, thermostat valves, water pumps, radiators, and radiator fans, and the appropriate materials of stranded wire, terminal blocks, plyboard, heat insulation foam, and acrylic. The trainer's functionality, aesthetics, and efficiency will be stringently tested against pedagogical and industry standards by alpha-beta testing. Data will be collected from a purposive sample of twenty, comprising ten automotive industry experts and ten highly qualified automotive instructors, by surveys and in-depth interviews. The findings are anticipated to yield useful insights for curriculum development, resource planning, and overall program quality improvement at the University of Science and Technology of Southern Philippines and potentially other academes. This development is intended to give Autotronics students the practicing skills and knowledge essential for success in the changing automotive industry, hence enhancing their employability and confidence.
