Vapour compression cycle generally known as VCC is a refrigeration cycle.
In this cycle, the refrigerant is sealed condition in an airtight mechanism is compressed in a compressor which permits the transfer of heat energy. The refrigerant absorbs heat from one place and releases it to another place. The system repeats over and over again and absorbs heat at low pressure from the refrigerant space.
Main Components of Vapour Compression Cycle
The principle parts which are used in this system are:
Let me discuss these components further on.
It provides the heat transfer surface through which heat can pass from the refrigerant space into the refrigerant.
It carries the low-pressure vapor refrigerant from the evaporator to the inlet of the compressor.
The function of the compressor is to compressed the vapor refrigerant to temperature and pressure to such a point so that it may be easily condensed.
It coveys the high pressure and high-temperature refrigerant from the compressor to the condenser.
It provides heat transfer surface and cools down the refrigerant by water spray or blow of air.
It stores the liquid refrigerant coming from the condenser and supplies it to the evaporator as per requirements.
It carries the liquid refrigerant from the receiver to the expansion valve.
It supplies the proper quantity of liquid refrigerant to the evaporator after reducing the pressure.
Working principle of Vapour Compression Cycle
It works as follows:
During suction stroke of the compressor, wet vapor refrigerant is drawn from the evaporator and compressed adiabatically to high pressure and high temperature
The high-pressure vapour refrigeration is then cooled in the condenser at constant pressure
The high-pressure liquid refrigerant is there expanded through a throttle valve or expansion valve and lower its pressure and temperature.
The low-temperature vapor refrigerant absorbs heat from the evaporator at constant pressure and cools the space. the vapor refrigerant enters the compressor during suction stroke and the cycle is repeated.
In this cycle, a large amount of work is required to compress the vapor refrigerant for increasing its pressure.
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 […]
