All the video lessons on this channel were made exclusively for students of the refrigeration technical course during the covid pandemic, as there were no face-to-face classes, and the practical classes were divided into small groups to avoid crowding. So I made the classes also available for anyone who wants to watch and is interested in learning a little more about refrigeration. I am very happy with this contribution of mine and I hope you enjoy the classes. A big hug!!!
