THEORY, CONSTRUCTION, AND OPERATION

Explanation: Every air conditioner (also pronounced as AC, A/C or Air Cooler in certain regions of the world) has got a compressor inside it.It works to compress and pump the refrigerant gas. Compression of refrigerant produces heat. To dissipate this heat, compressed refrigerant is pumped to the condenser coils where a fan blows the heat out to outer atmosphere.

DC MACHINES (17CA02301)

A DC machine is an electromechanical energy alteration device. The working principle of a DC machine is when electric current flows through a coil within a magnetic field, and then the magnetic force generates a torque that rotates the dc motor. The DC machines are classified into two types such as DC generator as well as DC motor.
