Refrigeration Cycle | Vapor Compression Cycle | Animation |

The refrigeration cycle is a thermodynamic process that is used in refrigeration and air conditioning systems to transfer heat from a low-temperature region (typically the conditioned space) to a high-temperature region (typically the surroundings). The purpose of the refrigeration cycle is to maintain a lower temperature in a controlled environment by removing heat from that space.
The refrigeration cycle consists of four main components: the compressor, condenser, expansion valve (or throttle valve), and evaporator. These components work together to circulate a refrigerant, which is a fluid with desirable thermodynamic properties for heat transfer.
Here is a brief overview of the four stages of the refrigeration cycle:
Compression: The refrigerant enters the compressor as a low-pressure vapor and is compressed, increasing its temperature and pressure.
Condensation: The high-pressure, high-temperature refrigerant then flows into the condenser, where it releases heat to the surroundings. As a result, the refrigerant condenses into a high-pressure liquid.
Expansion: The high-pressure liquid refrigerant passes through the expansion valve, which reduces its pressure and temperature. This causes the refrigerant to partially vaporize, entering the next stage as a low-pressure mixture of liquid and vapor.
Evaporation: The low-pressure refrigerant mixture enters the evaporator, where it absorbs heat from the conditioned space, causing the remaining liquid to vaporize. The vaporized refrigerant is then drawn back into the compressor, and the cycle repeats.
By continuously circulating the refrigerant through these stages, the refrigeration cycle removes heat from the conditioned space, keeping it cool, while releasing the absorbed heat to the surroundings.
It's important to note that the refrigeration cycle can be modified and optimized for various applications, such as domestic refrigerators, air conditioners, industrial cooling systems, and more. Different refrigerants and system configurations can be utilized based on specific requirements and environmental considerations.

Many technicians blame the TXV valve for a priblem in the refrigerant cycle because they never understand that if the condenser does not put out the fire of the heat of compression and condensation this heat will circulate in the system from one component to the other. The condenser is key, has to be kept clean (fins) and insure that the fans RPM are adecuate. How do you insure this? by keeping up and monitor both SUBCOOLING AND EVAPORATOR SUPERHEAT & COMPRESSOR SUPERHEAT.😊

Excellent...if u give values and temperature values also it would have been better..

[@padysrini9955]

At 1:44, you say low pressure/temp vapor enters compressor. At 3:25, output of evaporator is low pressure/high temp. But next step is input into compressor. Not matching. Or a step is missing.

[@zebralearningsenglish-pn6fl]

Actually both are correct. For example, in the evaporator we give temperature like 25°C. This 25°C is low temperature for us. But the refrigerant will boil at very low temperature. If we give 25°C the refrigerant will boil and evaporate. So, for the refrigerant 25°C is high temperature. If we feel 25°C is low temperature, we can say it is low. If we feel 25°C is high temperature, then we can say it is high.

Hai sir, I have doubt, At starting you said low pressure low temperature vapor is going inside the compressor., After the one cycle you saying low pressure medium or high temperature vapor?? How it’s possible?? Please explain i connfused

[@zebralearningsenglish-pn6fl]

Compressor inside gas liquid stage

[@numankhan3914]

What is the saftey of refrigeration cycle.

[@yuvaraj1386]

While explaing about evaporator it is explained that high temp low pr vapour is coming out from the evaporator then it is going to compressor, but initiallu you started explaining compreasor inlet is low temp low pressure vapour, how high temp vapour from evaporator becomes low temperature vapour at compressor inlet? Please clarify this

[@zebralearningsenglish-pn6fl]

Actually both are correct. For example, in the evaporator we give temperature like 25°C. This 25°C is low temperature for us. But the refrigerant will boil at very low temperature. If we give 25°C the refrigerant will boil and evaporate. So, for the refrigerant 25°C is high temperature. If we feel 25°C is low temperature, we can say it is low.

In compressor Mora liquid stage in Problem

[@brian1192]

At where the fan is blowing air on the evaporator side, is it blowing it into the evaporator coils or blowing them away to get cool air ?

[@zebralearningsenglish-pn6fl]

The fan blows air into the evaporator coils. This air passes over the cold coils, absorbing heat and cooling down.

[@chiefdenis]

The fan blows through the evaporator

[@user-so9yi9py1i]

Professor, can you send a link to a simulation program for cooling and heating systems for mechanical and electrical parts and control circuits? Thank you.

[@zebralearningsenglish-pn6fl]

I tried to find out, but I couldn't get the proper one. I will try to get the good one.

[@kannabiranm812]

Incase liquid goes through the compressor what happen

[@zebralearningsenglish-pn6fl]

The liquid is a incompressible thing, so the compressor can't compress the liquid and it will damage the compressor by giving more load.

[@genegonzalez4713]

My advice to you readers is this, unless the person is a qualified PE engineer with ASHRAE or ARI. Be careful with whatbyou watch on KZbin😅

[@zebralearningsenglish-pn6fl]

I want to know what mistake you found in this video?

[@genegonzalez4713]

Listen you clearly don't know the refrigerant cycle. From the compressor the refrigerant is discharged as superheated gas, frim hete tje first stage of cooling is called desuperheating this occurs at the top of the condenser, and it takes up 5% of the condenser. After this the 2nd stage of cooling is called condensation that takes up 85% of the condenser leaving only 10% fro the 3rd stage of cooling called subcooling. If for any reason these three stages of cooling do not take place the refrigerant will not be 100% liquid gas and the TXV valve will not be able to feed the evaporator because the gas will be in both liquid and gas. Remember the TXV creates the pressure drop only olif the refrigerant comes to the valve at 100% liquid. Many technician blame the TXV for their poir knowledge of the refrigeration cycle. If the condenser does not adequately cool the refrigerant there will existt a high (Liquid line pressure drop) in the Liquid line and this high presdure drop, (resistance to flow) will effect the refrigerant bringing it to the TXV in two forms gas and liquid. The Achilles tendon of the refrigerant cycle is in the liquid line its been this way since inception, I REPEAT!! THE KIQUID LINE IS THE WEAKEST POINT IF THE REFRIGERANT CYCLE. MANY MECHANICAL ENGINEERS STILL DON'T UNDERSTAND THIS 😢
