सवाल
Which syllabus does the Refrigeration and Air Conditioning Lab course follow?
It follows the AKTU (Dr. A.P.J. Abdul Kalam Technical University, Lucknow) B.Tech syllabus for Refrigeration and Air Conditioning Lab. If your own university's syllabus differs, the centre follows your university syllabus.
Will this help in the university examination?
Yes. Experiments are explained with aim, theory, procedure, observation table, calculation and viva questions, so you can write the lab file and face the practical exam confidently.
Is refrigerant handling safe for students?
Charging and leak testing are demonstrated by the trainer with gloves and goggles; students follow the safety rules.
