A Vapour Absorption Refrigeration System consists of these following parts:
In Vapour Absorption Refrigerant System the low-pressure refrigerant vapor (NH3) from the evaporator is absorbed in the absorber by a weak solution of refrigerant and lowers the pressure in the absorber to draw more NH3 vapor from the evaporator. The cooling system also used to remove the heat of solution to increase the absorption capacity.
The pumps draw strong solution (rich in refrigerant) from the absorber, builds pressure and forces in the generator. the strong solution of NH3 in the generator is heated by a gas or steam to drives out the NH3 in the generator is heated by a gas or steam to drives out the NH3 vapor to the condenser and weak solution returns to the absorber.
After condensing in the condenser, the liquid NH3 with high pressure is passed through a throttle valve to the evaporator where it absorbs its latent heat thus producing cold.
Actual Vapour Absorption Refrigeration System
In actual vapour absorption refrigeration system when heat-exchanger and rectifier are used with a simple system to improve operating efficiency than it is called Practical Vapor Absorption System.
The low-pressure refrigerant vapor (NH3) from the evaporator is absorbed in the absorber by the weak solution of refrigerant. The pump draws the strong solution of NH3, build high pressure and forces to the generator through a heat exchanger where weak solution acts as cooling media. Therefore reduce the cost of heating in the generator and cost of cooling the absorber.
The analyzer is a direct contact heat exchanger consisting of a series of trays mounted above the generator which remove some unwanted water particles associated with NH3 vapor going to the condenser.
The refrigerant from the analyzer enters the rectifier where the final reduction of water vapor occurs by cooling water circulation.
The liquid refrigerant from the condenser expands in the expansion valve and enter the evaporator cooling.
Now I love to hear from you, In this guide of VCC, I showed all-important point regarding VCC. And also I shared a couple of videos of Prof. Ravi Kumar. I am pretty sure you have already clear your doubts although If you wanna need some specific question regarding this please comment down below, I would reply to all of your queries.
In this article, I'm going discuss about Steam Condenser in briefly. At the end of this article, you will learn How a Steam Condenser works, Definition and Types of a steam condenser, and more. So let's get started. The Functions or Needs of a Steam Condenser: The functions or the needs of the condenser in […]
Today in this article I am going to give you an in-depth overview of Electron Beam Welding Machine. This Welding Process was first developed in 1949 by Karl-Heinz Steigerwald who was a German physicist. In this article first, we will see the Definition, How it's Work after that I'll also show you the Applications, Advantages, […]
In the field of mechanical engineering, the Extrusion Process is widely used by the engineers to form an object which has a fixed cross-sectional area. For making the object, the raw material is pushed into a die to provide it with the desired shape. The major function of this process is that the brittle materials […]
