For all other refrigeration & air conditioning 5th sem bteup diploma syllabus 2017 you can visit Refrigeration & Air Conditioning 5th Sem BTEUP Diploma Syllabus 2017 Subjects. The detail syllabus for refrigeration is as follows.
Rationale:
Refrigeration and Airconditioning is one of the needs of modren society and industry. It is already recognised so as it is futile here to say anything about its improtance or utility. For mechanical engineers this knowledge is an extra gem. The subject has been devided in two papers. This paper covers Refrigeration Plant, Erection and its maintenance.
