Training of Trainers: Building a Commercial Chiller Simulator Model

The refrigeration and air conditioning (RAC) sector is pivotal in modern infrastructure, essential for healthcare, comfort and the preservation of perishable goods. In July, GIZ Green Cooling Initiative together with the National Ozone Unit in Kenya organised a training of trainers (ToT) on building simulator models for commercial Chillers that use R290 refrigerant. That training was held in the National Industrial Training Institute (NITA) Mombasa.

Seventeen RAC trainers from across the country attended the 5-day training to improve their advanced technical knowledge and pedagogical skills on safe handling of natural refrigerants. These programs typically encompass a blend of theoretical and practical components. Trainers learn about mounting interior parts of commercial chillers using R290 refrigerants, energy-efficient systems, and environmental regulations. Emphasis is placed on understanding systems, troubleshooting techniques, and integrating sustainable practices.

Practical sessions we carried out in groups of three, providing hands-on experience with state-of-the-art equipment and simulations. In this field, it is crucial to ensure a skilled workforce capable of maintaining and advancing these technologies. The trainers completed the training and were urged to build similar models in their respective institution which will then be used to demonstrate proper techniques and assess learners’ performance.

The ToT program included learning soft skills such as effective communication between trainers and encourage innovation which was evident by the result that the final models build by various groups did not resemble. The trainers ascertained that the training had equipped them with skills to better manage classroom dynamics and foster an environment conducive to practical learning.

The partner ministry along side the Collaborating institute included GIZ Proklima for designing trainings that emphasize continuous professional development. At the end of the training, the trainers were encouraged to stay updated with industry trends, regulatory changes, and technological advancements. This commitment to lifelong learning ensures that the training remains relevant and that trainers can pass on the most current knowledge and practices to their students.
