What is Inverter Technology in Refrigerators?

Published On:

In modern days, refrigerators have become a necessary part of every household. They serve a principal purpose in our daily lives. Refrigerators help us to store food without worrying about spoilage. Before refrigerators became so popular, there was almost no way to preserve food properly. Though there were several ways to do so, they were nowhere near as convenient as the refrigerators. As technology advances, fridges have become more advanced. They come with various features installed nowadays. Based on the systems present, refrigerators can be of several types. It can differ between top freezer or bottom freezer kinds. There is also the side by side refrigerator models.

Besides, the types of refrigerators vary greatly, and with their varieties, their features differ as well. Nowadays, all but the smallest refrigerators come with auto defrosting technology. This system works by automatically melting the ice away in the freezer. But even with these numerous advanced features, they have one significant problem. They consume a lot of electricity. The refrigerators are probably the most used electrical appliance in the house. Therefore, refrigerator manufacturers always try to include features that cut down electricity consumption. The inverter technology is one such feature. But how many of us can say what that technology does? Well, in this segment, we are about to talk about inverter technology in refrigerators.

What is inverter technology?

First developed in Japan, the inverter technology allows refrigerators to run on electricity following its load. The compressor of the fridge uses this kind of technology and allows operating at different speeds. Compressors using the inverter technology can adjust their speed accordingly depending on the load of the refrigerator. If the fridge needs a higher power, the compressor will run faster and vice versa. The refrigerator running at a slower speed means less energy consumption. So, this is how the inverter compressors reduce the electricity consumption of the refrigerator.

The working process of an inverter refrigerator

Now let us take a look at how this technology works. First of all, you should know that the compressor speed depends on the input voltage frequency. The electricity supplied to the inverter is AC. The inverter takes this AC electric supply to convert it into DC. The DC electricity is then further converted into AC and might vary in its frequency. So, we can see that the inverter supplies electricity with varying frequencies to the compressor. It allows controlling the compressor speed efficiently and helps the compressor work effectively, depending on the load necessary for the refrigerator. This process is very efficient and can save up to 50% more electricity than the standard ones.

The importance of inverter technology in saving electricity

The principal value of an inverter refrigerator lies in the efficiency in regulating the cooling temperature. It is capable of maintaining the temperature effectively at several conditions. Suppose you open the fridge to take out something or put them in. During this time, you may leave the refrigerator door open for a prolonged time. Here comes the inverter compressor, which will detect the temperature fluctuation despite beginning operating at a higher pace. As a result, it maintains the waste of cold wind and lets the warm air come inside the refrigerator without overcooling or spending much energy. Additionally, the inverter compressors can sense the outside and inside temperature. As a result, it operates at full pace on summer days when the heat is high. On the contrary, it effectively reduces its energy in winter depending on the indoor atmosphere.

So, now that you have some knowledge about the principal and working process of an inverter refrigerator, it is time to check out their advantages. With technological advancement, this inverter system got a good reputation among the customers. But if you want to purchase any standard freezer, you have to look at the inverter refrigerators to know its principal benefits. So, now take a glance at those benefits mentioned below:

Exceptional Temperature Regulation

Temperature regulation

The inverter in the refrigerator has an accurate and powerful cooling feature due to its advanced mechanisms. In this technology, the compressor always slows down and never stops its operation abruptly. As a result, it can regulate temperature continuously. It automatically changes the compressor speed based on the food load and provides improved food storage conditions. Besides, it also observes the thermostat setting and works accordingly. Furthermore, this feature efficiently detects whether the refrigerator door is closed or open.

Quiet operation and low vibration

Quiet operation and low vibration

If you see any standard freezer, you may notice that the compressor operates at high speed and produces loud noises. But an inverter compressor begins its operation at low momentum and automatically changes the speed smoothly without any disturbance. As a result of this, it operates quietly, making low vibration to the entire system.

Extended life span

Extended life span

In most refrigerators, the compressor needs high power. It may experience ups and downs at the time of start-up. Therefore, it is not durable enough. On the contrary, the inverter refrigerators do not demand high power while starting up, as they never start at high speed or shut down unexpectedly. It naturally changes its speed smoothly, and as a result, the compressor does not experience much wear and tear. Therefore, it decreases the compressor damage, and in the end, you will get a compressor that lasts longer.

More advanced power

More advanced power

As opposed to a standard compressor, the inverter provides higher and more advanced power. It has a power factor of 1 unit. Besides, it helps the product operating at a more controlled speed. Therefore, you can save electricity also.

Comparison between a standard and an inverter compressor in a refrigerator

A compressor is a heart or backbone of a refrigerator, which determines its effectiveness. However, the standard compressors are not efficient, as they consume more energy than the inverter ones. Modern technology enables them to work more efficiently. But the primary difference between a standard and an inverter compressor is the way they work. The standard compressors work in the start and stop cycles.

It means that the generic compressors start and stop over and over while the refrigerator is on. When the unit restarts, it needs a high amount of energy. It is the reason for the very high electricity consumption of refrigerators. The reason why the standard compressors operate this way is simple. It is because they only have a single speed setting. So essentially, the standard ones run at the highest speed, and when the temperature drops below the set temperature, it stops automatically. It then restarts again at full speed when the temperature rises above.

This process is absent from the inverter compressors. They never stop while the refrigerator is on. An inverter compressor uses both the inside and the outside temperature to adjust its speed accordingly. As such, the energy consumption needed to restart the compressor is not necessary. When the temperature drops below, it runs at a slower pace and picks up the pace when the temperature rises. Below we have shared a table to display the principal difference between a standard and an inverter compressor.
