How Does A Refrigerator Work Top Full Guide 2021

Is it because you consider the refrigerator a part of your daily life? Do you ever wonder How Does A Refrigerator Work when something important is lost?

The refrigerator is an integral part of any kitchen. It also serves as a storage device for prepared and unprepared food. If your refrigerator stops working or makes unusual sounds, this is a serious problem.

There are many reasons that a refrigerator compressor can fail. We will now discuss the symptoms and solutions for the refrigerator compressor working.

Basic training

Ever wondered what your fridge does? You can watch the video below or read the text below to get an overview of refrigeration. You will learn about the main components of a refrigerator and what happens to the refrigerant throughout the fridge system.

What a refrigerator does

To keep food fresh, it is important to maintain a low temperature to prevent the growth of harmful bacteria. The heat transferred from the inside to the outside by a refrigerator is what makes it feel warm. You’ll see how this works in a moment.

What are a refrigerator’s main components?


The compressor is the heart of a refrigerator. It circulates the refrigerant through the system, adds pressure, and makes the refrigerant heat. This is similar to when you pump air into a bicycle tube. You can feel a heat rise in the pump as you compress the air.


The condenser is located on the backside of a refrigerator and is likely to be quite dusty. The refrigerant inside is cooled and condensed. This means it transforms from a gas to a liquid.


The refrigerator’s evaporator is inside the refrigerator. It is responsible for keeping the food in the fridge cold. The refrigerant transforms from a liquid to a gas by evaporation. This cools the surrounding area, creating the right environment for food storage.

Capillary tube

The capillary tube, a thin piece of tubing that acts as an expansion device, is a small piece of tubing. The liquid refrigerant flows through the tube and is sprayed into the evaporator’s low-pressure environment.


The thermostat controls the cooling process by monitoring temperature and switching the compressor on or off. The compressor is turned off when the sensor detects it is cold enough in a refrigerator. It switches on the compressor if it detects heat and starts cooling again.

How does a Refrigerator work

The refrigerator is one invention that has changed our lives. The refrigerator has allowed us to keep food fresh for many days. The refrigerator’s cold temperature slows down bacterial growth and preserves food longer. How does the fridge’s interior stay cold?

It is very simple to understand how a refrigerator works. Because you must push their energetic molecules together, gases get hotter as they are compressed into smaller volumes.

Expanding a gas makes it able to take up much more space because the heat energy contained in its molecules is now distributed over a larger volume, the temperature of the gas drops (it gets colder).

Another principle in a refrigerator is that if you have two temperatures that are not the same, the cooler surface cools down, and the colder surface heats up. This law of physics is known as the Second Law of Thermodynamics.

In the vapor compression cycle for a refrigerator, a special gas called refrigerant is used. It was previously CFC (chlorofluorocarbon).

CFCs have been deemed to be harmful to the environment, and HFC-134a is now used. Also known as tetrafluoroethane, it is also used in the refrigeration cycle. The refrigeration cycle is composed of various components, which are shown in Figures 1 and 2.

Fig. 2 Vapour compression or refrigeration cycle. This is how the components of a refrigeration cycle work together to cool your food.

1. The compressor constricts the refrigerant vapor, raises its pressure and temperature, and pushes it into the condenser’s coils on the outside of the refrigerator.

2. It becomes liquid when the hot condenser gas meets the kitchen’s cooler air temperature.

3. The refrigerant is now in liquid form at high temperatures. It cools as it flows through an expansion valve into the freezer’s evaporator coils.

4. When the refrigerant flows through the evaporator coils, it absorbs heat and cools down the fridge.

5. Last, the refrigerant evaporates to a gas due to raised temperature and then flows back to the compressor, where the cycle starts repeatedly.

The compressor is the main component of a refrigerator, and it requires power. The compressor is a pump that is driven by a motor. When the fridge is turned on, you will hear a hum. This is the compressor in action. The compressor controls the temperature by turning on and off the thermostat.


How does a refrigerator have energy?

The refrigerator draws energy from three components: the compressor fan, the condenser fan, and the evaporator fan. The compressor pumps the refrigerant through a refrigeration cycle using electricity. When the refrigerator is at the right temperature, the compressor can be turned off.

How do refrigerators work thermodynamics?

According to the Second Law of Thermodynamics, heat will always flow from hot to cold spontaneously and not the other way around. The heat from a refrigerator is caused to flow from cold to hot by the work it does.


How do you know if your fridge is dying?

Refrigerators usually emit a soft hum. However, if the appliance is buzzing loudly or has stopped working, it could solve its motor. Unplug the fridge and then plug it back in. Your fridge may be dying if it keeps buzzing.

Do refrigerators use a lot of electricity?

What is the Electricity Consumption of My Fridge? For example, a refrigerator with a top freezer that dates back to the 1980s and has a volume of 19.0-21.4 cubic feet would use approximately 2,000 kWh annually. A fridge that is Energy Star-rated might use only 350 kWh per year.
