How does a refrigerator work? This query is common that comes into our mind for the first time after owning a fridge. How does a fridge work like to cool our foods and beverages? The answer is straightforward; that is it takes the heat from the foods and makes them cool.

The primary functional process of a refrigerator is to keep the foods cold and fresh. Almost 47% of Indians in urban areas are using refrigerators to enhance their quality time. The people who are very in their daily life try to store foods and vegetables for a week/month. As a result, they can get some time to relax after returning home.

Therefore, if you want to buy a fridge then you have to know the refrigerator working process properly. Only the proper maintenance of a refrigerator can help us to increase its lifespan. Suppose, you found that you failed to get fresh food. As well as, you know the reason that the evaporator stop working.

So, you can easily find out the problem and make the right decision. Taking the right decision at the right time can minimize your repair cost. Remember, the longer it has the life span, the more you can stay happy.

Most of the people use refrigerators 15-20years during their lifetime. Therefore, you can maintain it properly if you know the refrigerator work principle correctly.

First of all, we have to know some essential things that are related to the refrigerator. Most people use refrigerators, but they don’t have any ideas about these facts. So, let’s talk about these essential facts.s.

What is Refrigerant?

Refrigerant is a compound Gas that can turn into a liquid at high temperatures. It can also turn into a vapor at a cold temperature. Also, It can absorb the heat from all kinds of surfaces and keep them fresh. 

This refrigerant gas is used for all kinds of cooling systems like air-conditioning, refrigerator, fridge, Ice-maker, Wine -cooler, and many more. Earlier the refrigerant gas was CFC (chlorofluorocarbon), which is very harmful to our Ozone layer. 

The advanced Gas of refrigerant is HFC(hydrofluorocarbon). The compound gases of HFC are also known as R-22, R-134, R-400, R-401, R-500, and many more. These gases do not have any effect on the Ozone layer. 

What is Refrigeration?

Refrigeration is a cyclic process by which you can keep your food cold and fresh. The cyclic process is to transfer heat from low temperature to high temperature. If you want to know-How does a refrigerator work? Then this information will definitely help you forever.

On the other hand, the high temperature again transfers to low temperatures. By using this method, it can keep the foods cold and fresh. Why do we keep our foods cool? The reason is to deactivate bacterias that grow in average temperatures. 

All kinds of bacterias like Salmonella enteritidis, Listeria monocytogenes, Escherichia Coli, Clostridium botulinum, Campylobacter, and others spoil or damp our foods. These bacteria formation can happen within an hour or day and months. By eating this kind of food may cause severe diarrhea, food poisoning, and vomiting.

Therefore, the formation of bacteria happens at average or high temperatures. But in the cold temperature, they stop formatting at 40°F or 4°C or less heat. The less temperature can cause less formation of bacteria and keep your foods fresh. 

So, by the refrigeration process, you can keep all your foods fresh and cool for some days and months.

Five Basic Components of Refrigerator

Every refrigerator has five necessary components for the refrigeration or keeps your foods cool and fresh. These components are essential for every fridge to work correctly. If any elements of the refrigerator stops working, then you fail to get fresh foods. 

Here are the name of these five components:

  • Compressor
  • Condenser
  • Evaporator
  • Expansion Valve
  • Capillary tube

Let’s jump right in the central part of this topic. You already know the name of refrigerator components and the refrigeration process. So, all the information can help you to understand the function of a refrigerator. 

How does a Refrigerator Work?

The refrigerator absorbs the heat from the foods and keeps the compartment cold. Continuous losing heat and because of the cold atmosphere, the foods remain cool. 

Earlier I discussed, in a cold environment, bacteria formation remains low. You can get your foods fresh for a long time because of the fewer bacterias formation. By doing this, the refrigerator has to maintain some steps.  

Do you want to know the best part of the functional areas of refrigerators? Let me explain the procedure with the five components, and you can understand better.

Evaporator

The primary function of an evaporator is to absorb the heat from the atmosphere and foods. The absorbed heat becomes vapor because of the low-pressure refrigerant in the evaporator. After making all the heat into Gas, it transfers the vapor into a thin pipe, called a capillary tube.

Capillary tube

The capillary tube is a thin tube other than the evaporator and condenser. In this tube, the vapor becomes pressurized and passes through the compressor. When the Compressor turns on, then it sucks the Gas from the tube. 

Compressor

Do you want to know how to work the refrigerate compressor? The central role of the Compressor is to create high-pressure to the vapor.

When the Compressor compresses the vapor in high pressure, the vapor becomes so hot. The hot vapor or Gas then passes through a tube which is called a condenser.

Condenser

The condenser is made with a tube and fence that helps to discharge heat rapidly. At the first step, the condenser discharge heats outside and makes the vapor cool. After passing all the heat, slowly the vapor turns into liquid. 

This liquid then goes to the filter and becomes clean. After filtration, the fluid passes through to the Expansion valve.

Expansion Valve

The main characteristic of the expansion valve is to expand the pressure of the liquid. After it throws the fluid to the evaporator. When the liquid loses its force, it also loses its heat. After that, it passes to the evaporator from high pressure to the low-pressure area.

In the evaporator, the liquid becomes cool and turns into a gas again. The evaporator then discharges the cold Gas by using a fan into the compartment. The food and compartment become cool. 

On the other hand, it also absorbs heat from them. By doing this process in a cycling way, the foods become cool and fresh.

You can understand all the processes by concentrating on the refrigerator diagram.

This is additional information which can help you to give a new look and help to manage your memo. The fridge magnet is an ornament that we often use to keep our list in front of our eyes.

Sometimes we use the magnet only because of the beautification of our refrigerator. There are lots of fridge magnets we can find in the market or online shop.

Conclusion

How does a refrigerator work?? If you know the answer then it can help you to keep your fridge safe and sound. If any of these components like the Compressor, condenser, and others may fail to work. You can easily understand. After that, you can call the repair service people to help you. 

The identification of the problem of the appliance is also crucial to keep them safe. The more frequently you understand the problem, the more rapidly you can solve it. By doing this, you are helping to increase the lifespan of your refrigerator.
