AmmoniaWater Vapor Absorption Refrigeration System The working of ammoniawater absorption refrigeration system is based on the simple vapor absorption refrigeration system. In this system ammonia is used as the refrigerant and water is used as the absorbent. working of simple vapour absorption system

May 15, 2017 hiii friends In this video I have explained about simple vapour absorption system. The vapour absorption refrigeration system is one of the oldest method of producing refrigeration effect

Sep 09, 2015  Simple Vapor Absorption Refrigeration System. 8. Absorption system requires a relatively large amount of low grade thermal energy at generator temperature to generate refrigerant vapour from the solution in generator. Thus while the energy input is in the form of mechanical energy in vapour compression refrigeration systems, In this article we will discuss about simple vapour compression refrigeration system. Introduction to Vapour Compression System: For a closed cycle of refrigeration employing the condensable refrigerant vapour, the following processes are required: (i) Compression of the vapour working of simple vapour absorption system Apr 22, 2015  In a vapour absorption system, the compressor is replaced by a pump and a heating unit in order to save power. Take an example of ammonia water vapour absorption system, in which ammonia the refrigerant leaves the evaporator in the vapour state, water has the capacity to absorb ammonia

The pressure of the liquid is reduced to the absorber pressure by the throttle valve. Comparison between Vapor Compression and Absorption system: a) Uses low grade energy like heat. Therefore, may be worked on exhaust systems from I. C engines, etc. a) Using highgrade energy like mechanical work. working of simple vapour absorption system Description of the vaporcompression refrigeration system. The condensed liquid refrigerant, in the thermodynamic state known as a saturated liquid, is next routed through an expansion valve where it undergoes an abrupt reduction in pressure. That pressure reduction results in the adiabatic flash evaporation of a part of the liquid refrigerant. Explain the working of simple vapour absorption refrigeration system. Answer: Working of Simple Vapor absorption system: A Simple Vapor absorption system consists of evaporator, absorber, generator, condenser, expansion valve, pump& reducing valve. In this system ammonia is used as refrigerant and solution is used is aqua ammonia. The objectives of this lesson are to: 1. Introduce vapour absorption refrigeration systems (Section 14. 1) 2. Explain the basic principle of a vapour absorption refrigeration system (Section 14. 2) 3. Compare vapour compression refrigeration systems with continuous vapour absorption refrigeration systems (Section 14. 2) 4. Simple salt and water system. A simple absorption refrigeration system common in large commercial plants uses a solution of lithium bromide and lithium chloride salt and water. Water under low pressure is evaporated from the coils that are being chilled. The water is absorbed by a lithium bromidewater solution.
