Thermoelectric Refrigeration System Working: Thermoelectric Refrigeration System works on the principle of Peltier effect according to which heat energy is evolved at one junction and absorbed at the other one when direct current is passed through a junction of two dissimilar metals like antimony and bismuth. It consists of a number of thermoelectric module assemblies

Explain Vapour Absorption Refrigeration System: The vapour absorption refrigeration system is one of the oldest method of producing refrigerating effect. The refrigerant, commonly used in this system, is ammonia. This system uses heat energy, instead of mechanical energy as in vapour compression systems, in order to change the conditions of the refrigerant required for the

Explain Vapour Compression Refrigeration System: Vapour Compression Refrigeration System is the most important system from the standpoint of commercial and domestic utility and most practical form of refrigeration. The working fluid, known as a refrigerant, used in this vapour compression refrigeration system readily evaporates and condenses or changes alternately between the vapour and liquid phases

Refrigeration Cycle Diagram: For lowering the temperature of a body below that of its surroundings and then maintaining its temperature at this lower level, a continuous extraction of the heat from the body is required. The lowering or producing of low temperature in a body or a space is accomplished by a mechanism called the
