Working Principles of Inverters in Refrigerators

04 December 2020

Refrigerators have been very useful in households and businesses in storing products under low temperatures. This specific appliance works by maximising refrigerant. The refrigerant is intended to flow through the coils or pipes and absorb the heat from products that are stored on the refrigerator. As the heat is absorbed, the refrigerant evaporates into a gas, which then cools the stored products. The compressor, at this point, will then compress the gas through increasing the pressure, turning the gas into liquid again. The cycle of the refrigerant continues as long as the refrigerator works well.

Normally, the compressor of the refrigerator is designed to carry out its cooling function at one speed. This component is known to run at the highest speed and only stops whenever it goes 1 or 2 degrees below the set temperature of the thermostat. If the set temperature is 1 or 2 degrees above, then the compressor will start to run again. This component is known to use energy whenever it starts running.

Inverter Technology Principles

And with the continuous usage of energy, conventional compressors are known to take up huge operating costs. Additionally, the on and off cycles of these compressors can affect the quality of products as they may get spoiled more quickly due to the variations in temperatures. 

Fortunately, the inverter technology is now integrated with most refrigerators today. This technology allows the compressor to keep running regardless of the inside, outside, and set thermostat temperatures. Both the speed and power are likewise adjusted accurately by the inverter, which would depend on the operating needs of the refrigerators. During hotter days, the inverter can make the compressor work at its maximum. Alternatively, it allows the compressor to work less during colder days. 

The varying operations of the inverter technology are possible since it is regulated by changing the frequency of the incoming voltage input. This technology likewise still has on and off cycles. However, it would take longer at low speed, keeping the temperature more stable.

Benefits of Inverter Technology

Inverter technology has brought multiple benefits to modern refrigerators. Here are some of the benefits of inverter technology in refrigerators.

• Enhanced Temperature Control: Inverter technology allows refrigerators to obtain more accurate and precise cooling operations. The operations of this technology do not only depend on the outdoor temperatures or pre-set thermostat, but they also depend on the number of products that are stored and can be found inside the refrigerator. 
• Improved Vibration Levels: Refrigerators used to produce loud noise and strong vibrations. But with the incorporation of the inverter technology, refrigerators now run at lower noise and weaker vibration levels. Decreasing these elements allows the refrigerators to run optimally and achieve longer service life. It also allows the users to experience more quiet experience with them, even under heavy load and condition.
• Increased Energy Savings: One of the most popular benefits of inverter technology is that it can provide huge energy savings. Since it can adapt to the needed refrigerator load, it does not have to start and stop continuously in just one speed. It even runs at low speeds, allowing the refrigerator to spend lower electricity and energy under lighter or cooler load. It is known that this technology can save for up to 20 to 30% of energy bills.
