Rancang Bangun Alat Pratikum Mesin Pendingin Dengan Variasi Tekanan Kompresor

Abstract

In the world of lectures, the need for learning support media is very necessary because it is one of the most important parts in applying a theory. Especially in the mechanical engineering department, it is very necessary to have learning media for practicum in special subjects. learning media is very influential on one's understanding compared to without learning media. Therefore, in this research, a refrigerant practicum tool is designed in order to understand and recognize the processes and cycles that occur in refrigerants in applying the theory of thermodynamics learning by varying the pressure using a dimmer where there are 4 variations in the pressure. level is the highest or maximum to the lowest level 1 or minimum. When the dimmer is set at the level point, the resulting high press and low press will be standardized without using a dimmer, because at level 4 there is a level max and it has not had an effect on high press and low press. However, when the dimmer is set at level 3, 2, and 1, the difference will be seen because the results of the high press and low press at each level that are set will continue to drop at each level, and aim to determine the relationship between press and variation.
