Refrigeration and Air conditioning
•Cold air at the exit of the turbine flows into a room or cabin and cold HX doesn’texist. •Will take fresh air for next cycle. •In such a case, the low side pressure will be atmospheric. Closed systems •The same gas (air) flows through the cycle. •Low side pressure can be above atmospheric. •These systems are known as denseairsystems.

MODULE 5 SHEET METAL OPERATIONS
www.rajagiritech.ac.inSheet bending Sheet bending is defined as the straining of the metal around a straight axis. During bending operation, the metal on the inner side of the neutral plane is compressed, and the metal on the outer side of the neutral plane is stretched. Bending causes no change in the thickness of the sheet metal.

FORGING
www.rajagiritech.ac.inRoll forging In this process, the bar stock is reduced in cross-section or undergoes change in cross-section when it is passed through apair of grooved rolls made of die steel. This process serves as the initial processing step for forging of parts such as connecting rod, crank shaft etc.

www.rajagiritech.ac.in•A multi-stage system is a refrigeration system with two or more low-side pressures. •Multi-stage systems can be classified into: a) Multi-compression systems b) Multi-evaporator systems c) Cascade systems, etc. •Two concepts which are normally integral to multi-pressure systems are, i) flash gas removal, and ii) intercooling.
Gas Turbine Combustion Chamber
www.rajagiritech.ac.in→Combustion in the normal, open cycle, gas turbine is a continuous process in which fuel is burned in the air supplied by the compressor; an electric spark is required only for initiating the combustion process, and thereafter the flame must be self-sustaining. →Combustion of a liquid fuel involves the mixing of a fine spray of droplets with
