A Study on Refrigeration

Poonam Dhankhar


Abstract: Refrigeration is a basic method of food preservation. All the refrigeration methods for food preservation are based on Reverse Carnot cycle; which explains Adiabatic and Isothermal Expansion and Compression. Basic components used in these cycles are Evaporator; Compressor; Condenser and Expansion Valve. Generally used cycle is Vapor Compression Cycle. Other cycles are Vapor Absorption Cycle; Gas Cycle. Other new methods of Refrigeration are Thermoelectric and Magnetic Refrigeration. Various types of refrigerants are used in these cycles based upon their properties. Commercially Refrigeration is used as preservation method in various food industries like Dairy and Meat Processing industry.


Keywords: Food preservation, reverse carnot cycle, evaporator, compressor, condenser, vapor compression cycle, Thermoelectric and Magnetic Refrigeration
