Centrifugal Compressors - Chillers HVAC

The lecture talked about the centrifugal compressor that is used in air conditioning in buildings, how it works, the main parts of the intake line, the ejection line, and electrical connections, in addition to the refrigerant transport pipes. Explanation with pictures and different shapes of gas flow and heat exchange in the condenser. The parts of the compressor, guide vane and diffuser, are explained. impaler motor driver The pulling process generates centrifugal force that creates high speeds in addition to an increase in pressure, generating kinetic energy. Finally an explanation
Work done by compressor
F=m.r.[w]2
Force=mass. Radial. Velocity radian
And more examples
W= mass- (Enthalpy2-Enthalpy1)
W= m(h2-h1)
