Refrigeration and Air-conditioning

Refrigeration and Air-conditioning. Instructor: Prof. Ravi Kumar, Department of Mechanical and Industrial Engineering, IIT Roorkee. This Course provides a simple understanding of Refrigeration and Air-conditioning fundamentals. Ideally suited to those with a little or no knowledge of the subject. The course consists of different refrigeration cycles and understanding of psychrometry and psychrometric processes used for the purpose of air-conditioning. Further, the comfort air-conditioning and indoor environment health are also addressed in this course. (from nptel.ac.in)
