Thermal engineering is a branch of science that covers energy conversion from one form to another, working of IC engines, modes of Heat transfer, principles of refrigeration and air conditioning etc. The field of thermal engineering includes a lot of applications that can be classified as the combination of thermodynamics and heat transfer, such as IC engines, air conditioning and refrigeration systems. The objective of this laboratory is to provide the student a good environment to understand some very important concepts and applications in the field of IC engines and refrigeration. For performing practical of these subjects, department having Refrigeration & Air Conditioning Test Rig. [RAC Trainer/Bench], Window AC Test Rig, Vapour’s Absorption Refrigerator, Separating and Throttling Calorimeter, Stefen Boltzman’s Apparatus, Thermal conductivity of insulating powder, Emissivity Measurement Apparatus.
