Interactive Model of a District Cooling System in a Cogeneration Plant

The interactive model of a district cooling system in a cogeneration plant is the model that allows researchers, students, and lecturers to know how the system of district cooling works. Basically, the method of teaching with chalk and talk from the lecturer to explain how the system run resulted in low understanding. This is because the real plant of the district cooling is huge and located far from the Institute of Politeknik Ungku Omar. In the program structure of Diploma in Mechanical Engineering (air conditioning and refrigeration), students in semester 4 must study the course of Air Conditioning and Refrigeration System which consists of the subtopic for district cooling system. Therefore, an interactive model of the district cooling system in cogeneration plants is developed for teaching and learning material. The most interesting part of this model is the synchronization between the models with the mobile application. Thus, the lecturer can explain with an attractive mode and the students can access and easily understand the function of each component of the district cooling system. The application is only available on android devices. From the pre- and post-test of using the interactive model, it is shown that the results of the theory test for Air Conditioning and Refrigeration System increased by 44%.
