What is Refrigeration How Coldness made in Ref System

Today i am writing about a basic post about refrigeration, in this post will know about what is refrigeration and how can we make produce of coldness in refrigeration process. As you know refrigeration is big branch of sciences and its also a part of electrical technology but it is also another big technology.

What is Refrigeration?

The process from which we can produce coldness is called refrigeration, or in simple words the method from which we can produce the cooling and safe our food and fruits for little long time. Or we can also said that, the method from which we can transfer the heat from a mass to air and water.

How to produce coldness in Refrigeration?

In ref/ refrigerator machine, in a part vapours make form liquid which is called the evaporator. In this process the liquid got heat form the metal for changing in the vapours and the surface become cold.
                                                                    OR
We can said that the procedure in which we can change the liquid to vapours for making coldness is called refrigeration system. The refrigeration system can be done by different method and further we will write about it soon.

I think you did not understood that why in refrigerator coldness is produce, i want to share with you a short example which help you more.
For example if you drop petrol on you hand, you will see that in a short time the petrol change in to vapours or air and you will feel coldness, its means that the petrol require heat to change him self to air and petrol got the heat from your hand. Same the refrigeration cycle and system working on this system.

Advantages of Refrigeration

Before refrigeration and air condensation innovation we can not use the food, meat , vegetables, fruits for a long time and we can only use it between some hours. After innovation of refrigeration now we can use for a long time. Before Ref we can not make cooling in a room easily but after refrigeration technology come we can do it very easily and in a short time. Thats is the power of refrigeration technology.
