Thus if a conventional refrigerator needs 5 kW inverter to power it, and inverter refrigerator of the same volume can be powered just by a 2 kW or 3 kW inverter.
How does refrigerant work?
The refrigerant (refrigerant is the liquid that flows inside the pipes of evaporator and compressor) flows through the evaporator and absorbs the heat from inside of the refrigerator and cools down the space, the absorbed heat makes the refrigerant to evaporate and become vapour. This vapour is then compressed in the compressor where its pressure ...
What are the main components of a refrigerator?
Every refrigerator has two main components viz., compressor and evaporator that does the cooling and the rest of auxiliary components help them in doing that. The inside wall of your refrigerator has evaporator and on the back side at bottom there is compressor.
What type of compressor is used in a refrigerator?
Most compressor be it in a conventional or inverter refrigerator are of rotary type. A regular rotary compressor has to convert the rotary motion of an electric motor to linear motion with the use of a crank shaft and piston rods to compress the refrigerant.
How does an inverter compressor save power?
Hence inverter refrigerator saves power by adjusting its compressor speed as per the load on the refrigerator. ...
Why is my inverter refrigerator so slow?
Unlike a conventional refrigerator which is quite fast in cooling, an inverter refrigerator is a bit slow presumably, due to slow start-ups of compressor. The difference in the cooling time isn’t drastic but a small one which can be overlooked keeping in mind the amazing advantages it offer.
How does a refrigerator work?
Refrigerators work by harnessing the power of the evaporation process to cool down their compartments. It does this by continuously evaporating and condensing a refrigerant gas that runs through copper tubes inside the refrigerator. This gas is circulated throughout the refrigerator’s copper tubes by a device called the compressor.
What is an inverter compressor?
Simply put, an inverter is a device that controls the frequency of the incoming electrical current that goes to the compressor; this allows the compressor to operate at variable speeds.
Why does my refrigerator keep roaring back to life?
To maintain the temperature inside the fridge, the refrigerator’s thermostat tells the compressor to either stop or start when it gets too cold or too warm. This is why you hear your refrigerator roaring back to life after a few moments of it being silent.
What does it mean when a non-inverter compressor runs at a fixed speed?
Non-inverter compressors run at a fixed speed, which means that their control of the temperature inside the fridge is limited. In extreme cases, you will hear it short-cycling.
How does a compressor work?
This means that the compressor works at peak load until it reaches the temperature that you’ve set. After that, it turns off completely; there is no middle ground. Compressors use the most amount of power during startup; a lot of energy is wasted since non-inverter compressors stop and start multiple times a day.
What is the heart of a refrigerator?
This gas is circulated throughout the refrigerator’s copper tubes by a device called the compressor. Most of the electricity consumed by your refrigerator is due to the operation of your compressor. This is why it is often called the “heart” of the refrigerator.

Why is an inverter refrigerator more efficient than a traditional refrigerator?
An inverter refrigerator is more efficient when compared to traditional fridges. That is because it can control the amount of cooling as per requirements. The rating on a refrigerator tells the consumer how much of electricity a product will consume, typically in a year.
How efficient is an inverter compressor?
An Inverter Compressor is exceptionally efficient. It regulates itself with the cooling load, but it also knows how to adjust in various situations. For instance, when you open the refrigerator to put in items or take them out. In this situation, you might leave the door open for an extended period.
How does the refrigeration process work with the compressor?
A refrigerator uses a coolant, usually HFC-13a, which flows through the coils or pipe behind it. This coolant absorbs the heat from inside the fridge. Afterwards, it evaporates it into gas and cools the items inside.
Why does my refrigerator make a loud noise?
Typical refrigerators make loud noises, as the compressor often runs at high speed. An Inverter compressor, on the other hand, starts at low speeds. It always transitions between speeds smoothly, reducing noises.
Why is my refrigerator cooler so precise?
Cooling is precise due to the smart mechanisms of the Inverter technology in the refrigerator. The speed of the compressor changes according to the food load, outside temperature. It also recognises thermostat settings and whether if the door is open or closed.
What is the difference between a compressor motor and an inverter motor?
Standard compressor motors have low power factors. In contrast, Inverter compressors offer higher ones. Additionally, there is a penalty on low power factors and a discount on higher ones for commercial use. An inverter motor has a power factor of around 1 unit.
Why does my refrigerator compressor work at a higher speed?
In this situation, you might leave the door open for an extended period. The compressor will sense the change in temperature and start working at a higher speed. That is to to make up for the loss of cold air without wasting electricity on overcooling.
How does a compressor with inverter technology work?
A compressor with inverter technology works very much like a car accelerator. When the speed required is more, the acceleration is more, and when it is less, and then the acceleration is less. This makes sure that during summer months when cooling load is more, the compressor works at peak capacity taking more electricity. But during winter months when cooling load is less, the compressor works less there by consuming less electricity. Even in summer month, the night temperature is less than the day temperature and thus electricity savings happen in night when compressor can run at a lesser speed.
How much current does an inverter need?
But Inverter Technology air conditioners and refrigerators have variable speed motors that start up gradually needing much lesser current at startup. Thus the size of inverter/generator required to startup is less. For e.g. A 1.5 ton fixed speed AC that runs at about 10 Amp current may need up to 30 Amp current at startup and thus a 5 kVA inverter/generator. But an inverter technology Air Conditioner needs about 6-7 Amp current and not much more at startup and thus a 1.5 kVA or 2 kVA inverter/generator is good enough to support it.
Why do refrigerator compressors run at peak load?
Every time the refrigerator door is opened, heat enters the refrigerator and the compressor has to take care of this load as well.
How does a refrigerator work?
Similarly in a refrigerator there is a refrigerant called HFC (Hydro Floro Carbon) that moves in the pipes or coils on the rear part of the refrigerator. When it is in a liquid form, it takes the heat from the refrigerator contents and evaporates to form gas there by cooling the things kept in the refrigerator. The gas is then compressed using a compressor to convert it into liquid again, and the cycle continues. The compressor uses electricity to do its job and is the most electricity consum ing part of a refrigerator.
What is the most energy consuming part of a refrigerator?
The compressor uses electricity to do its job and is the most electricity consuming part of a refrigerator. Refrigerator also has a device called “Thermocouple” which senses the temperature inside the refrigerator and makes the compressor go “on” or “off”.
