How Do Refrigerators / Fridges Work?

Here’s what’s going on inside your refrigerator right now! If you’re like most people, you don’t think about the inner workings of your refrigerator until it breaks down or needs to be replaced. To get the most out of this vital device. It’s helpful to understand how it keeps your food cold and the Fridge repair service in Pune is there to help. Continue reading to learn everything you need to know about how a refrigerator works and how it keeps your food cool.

Here’s An Amazing Idea

A metal box that keeps your food fresher for longer! Have you ever considered how a refrigerator manages to stay cool, calm and collected even in the sweltering heat of summer? Bacteria breed inside food, causing it to spoil. Bacteria, on the other hand, grow slower at lower temperatures. Thus, the cooler you can keep food, the longer it will survive.

A refrigerator is a contraption that uses sophisticated technology to keep food chilled. While your refrigerator is running, liquids change into gases, the water turns into ice, and your food remains pleasantly fresh. Let’s take a deeper look at the working of a refrigerator!

The Coolant: How heat is constantly transferred from inside to outside

As it enters the expansion valve, the coolant is a pressurized liquid. As it passes through, the abrupt drop in pressure causes it to expand, cool, and partially transform into a gas.

The coolant boils and turns entirely into a gas as it circulates the chiller cabinet, absorbing and removing heat from the food inside.

The coolant’s temperature and pressure rise as the compressor squeezes it. It has now turned into a heated, high-pressure gas.

The coolant circulates via tiny radiator pipes on the rear of the refrigerator, dissipating heat and cooling back into a liquid as it goes.

The coolant returns via the insulated cabinet to the expansion valve, and the cycle begins again. As a result, heat is constantly transferred from inside the refrigerator to the outside.

How Does a Fridge Function?

Although it appears to be quite appealing, the coldness would not stay long because your normal refrigerator cannot cool that well.

But how does a fridge function, and how does one cool thing down? The temperature of an object is determined by how much the molecules/atoms within the object move.

It is simple to imagine how to heat something, such as by placing it over a fire. However, to chill something, you must take energy and slow the molecules in it. To cool things down, you need something cooler than the object. But how can you cool anything off in the first place?

By The Might Of Physics

Humans are an excellent example; we can cool off by sweating. Our body’s excess heat is transmitted to the water in sweat. Which subsequently evaporates. The heat from the body was lost to the water on its skin, which “used” the heat to evaporate. This is known as evaporation.

A material that transitions from the gaseous to the liquid state while losing heat is Known as condensation. When you take a hot shower, this is what occurs. When the hot water vapor from your shower strikes a cold mirror, it loses heat to the mirror. This cooling causes the water vapor to condense into liquid water, which appears as droplets on the mirror.

These Two Processes Are Critical for Understanding How a Refrigerator Operates

Cooling a thing requires transferring its heat to another object/substance.

Temperature variations are caused by changes in pressure. This is why a bicycle pump gets hot when you compress the air and a spray deodorant gets cold when you open the nozzle and let the compressed liquid expand into a gas. Fridges use these principles to keep your food chilled.

Now that you understand how a fridge works, you should recognize that leaving it open will not help. The refrigerator cools by transferring heat from the inside to the outside ambient air via a refrigerant acting as a “heat transport vehicle.” This is why, in the winter, you can acquire a portable heater but not a portable air conditioning system. To shed heat, air conditioning systems require a connection to the outside environment.

The greatest way to stay cool in the summer is to invest in a fan. It will promote heat transfer from your body to the surrounding air by supplying fresh air that you have not yet heated up. And if it’s hot enough that there’s no significant heat transmission. It will at least improve sweat evaporation on your skin.

The Operation of a Refrigerator System

Refrigerators function by converting the refrigerant circulating inside them from a liquid to a gas. This process cools the surrounding environment and achieves the intended effect. You can try this technique for yourself by putting a drop or two of alcohol on your skin. You should feel a cold when it evaporates – the same basic concept that allows us to store food safely.

The pressure on the refrigerant must be decreased through an outlet known as the capillary tube to begin the evaporation process and turn the refrigerant from liquid to gas. The impact is comparable to that of using an aerosol product, such as hair spray. The pressure/liquid side of an aerosol can is represented by the contents. The outflow by the capillary tube, and the open space by the evaporator. When the contents are released into the lower pressure open area, they change from a liquid to a gas.

To Keep a Refrigerator Functioning

You must be able to return the gaseous refrigerant to its liquid state. Which requires compressing the gas to a greater pressure and temperature. This is where the compressor enters the picture. As previously stated, the compressor functions similarly to a bicycle pump. While pumping and compressing the air, you can feel the heat build in the pump.

The gas should be under high pressure and heated when the compressor has finished its task. It must be cooled in the condenser, which is located at the rear of the refrigerator and allows the contents to be cooled by the ambient air. When the gas inside the condenser cools, it transforms back into a liquid.

The liquid refrigerant then circulates back to the evaporator, where the process begins again.
