Full form of VCRS

Vapor Compression Refrigeration System

Full form of VCRS is Vapor Compression Refrigeration System, actually this is a cycle which consists couple of processes which provides us cooling effect lower than surrounding we can also say that we can desire temperature, well this is a part of a mechanical engineering subject, means every mechanical engineer learn about this system.

Because there is a subject whose name is Refrigeration and Air Conditioning in short we know it as RAC, this is one of the important as well as interesting subject in whole mechanical engineering, because those wanted to choose refrigeration and air condition sector as earning point of view for them this subject really play important role but to have very good grab on this subject one need to have basic concept on thermodynamics, because thermodynamics is the base of it.

How VCRS Works-

Well, if you will see a diagram which is given below then you can understand about it much better way, actually it consists of four important devices which help to get desire output, let me tell you first about

Compressor- It is working in VCRS to increase pressure and temperature both of refrigerant

Condenser- Just after compressor there we install condenser to decrease the pressure of refrigerant and to maintain same pressure

Throttle Valve- This is one of the important valves which help to decrease pressure and enthalpy remains constant.

Evaporator- It absorbs heat from the system and because of this the outcome temperature of the refrigerant has been increased but pressure remains constant.

So, these four components are main component of this system, as I have shared with you about these four components like the same these are installed serially in system

In this system we are using compressor that’s why its name is Vapor Compression Refrigeration System.

 

I hope the diagram make you understand many critical issues, one more thing which I did not clear in this article that is about refrigerant because it is refrigerant which helps to get us desire effect without refrigerant it is not possible, so we must know about refrigerant and more important which refrigerant we must use, at least for domestic purposes.

Actually, there are many types of refrigerant but let me tell you broadly like-

1. Hydrocarbons
2. Saturated Hydrocarbons and there are others too.

But most important term while choosing refrigerant, we choose refrigerant according to purpose of use, see we want to choose a refrigerant then we will choose brine that means salt water.

But, if we will choose refrigerant for ice plant then we will choose ammonia as our refrigerant its chemical formula is NH₃ but what about our domestic refrigerator.

I mean what type of refrigerator we must use, actually if you are little familiar with refrigerator then you must heard about three star, five star refrigerator right, I hope so, because in TV even we have seen many times on advertisements, but that is about energy savings, but another thing which we must include in this article that is about Chlorine free refrigerant, actually now a days we are using chlorine free refrigerant because chlorine is harmful for our ozone layer which is protecting us from harmful rays.

Most promising chlorine free refrigerant is R-134, if you will see back side of refrigerator then even you will this or you will see there is written environmental friendly refrigerator.

So, if you are thinking about buying refrigerator then you must of think about this.
