The unique and elegant design of LG refrigerators can fully demonstrate the creativity and personality of consumers themselves.
2. Good fresh-keeping ability. LG refrigerators can adjust the temperature of the refrigerated and frozen areas, which can greatly improve the quality of food preservation.
3. The LG refrigerator is equipped with a self-developed direct drive inverter compressor (linear inverter compressor), which is the powerful "heart" of the refrigerator. LG's proprietary inverter technology ensures that the compressor can automatically adjust the working mode. Even if the outside temperature changes, the inner cold air can cover the refrigerator evenly, with good cooling effect, low noise and stable performance.

Figure 2: LG MoodUP refrigerator.
This year LG released a MoodUP refrigerator, equipped with a color-changing LED door pane. You can adjust the color of the refrigerator according to your mood, and this series shows unparalleled interior design flexibility.
LG's new refrigerator also provides an audio experience through a built-in Bluetooth speaker, and when the speaker plays audio, the LED panel of the MoodUP refrigerator can change color in sync with the music.
Additionally, when the refrigerator door sensor detects that the freezer has been open for too long, the panel on the door will flash repeatedly to let the user know the door needs to be closed.
When the motion sensor of the MoodUP refrigerator detects that someone is approaching, the panel flashes to greet you.
2. Samsung
We have no doubts that you have heard of this brand and used at least some of its products in your lifetime. While Samsung is known for making the latest and greatest smartphones, they haven't let us down when it comes to other home appliances like refrigerators.
Samsung has been providing the best products for a long time and has earned the trust of customers worldwide. Refrigerators from this brand are energy efficient, and look great too.
You can find several models and different types of refrigerators from this brand, which means that you will have a variety of choices, and you can easily get a refrigerator with optimal functions, good controls, and high reliability.
2.1 Samsung Refrigerator Design Features

1. Using inverter compressors and advanced computer control technology, on the basis of comprehensive energy saving, it achieves the comprehensive effect of keeping food fresh lastingly and reducing noise. With the use of fully fluorine-free refrigerant R600a, it will not destroy the ozone layer and produce a greenhouse effect, and does fully support green environmental protection.
2. Samsung smart refrigerator has multiple airflow cooling, and each shelf is supplied with cold air to balance the temperature inside the refrigerator. After the refrigerator door is closed, it will quickly reach the temperature you set, so that your food can be better preserved.
3. Samsung's frost-free preservation technology provides an optimal storage environment for your fresh fruits and vegetables. There is no frost in the box, which saves you the trouble of cleaning, so that you can get natural and fresh fruits and vegetables at any time
3. Whirlpool
Whirlpool has been producing refrigerators since 1955 and owns many well-known international brands such as Whirlpool, Maytag, KitchenAid, Jenn-Air, Amana, Brastemp and Bauknecht.
The Whirlpool brand now has a solid reputation for producing the most energy-efficient refrigerators and other electronics. The brand has a wide range of refrigerators, and you can easily find them in all shapes and sizes, as well as with different smart features.
You can find technologically advanced refrigerators such as single door, double door, and multi door. Whirlpool refrigerators are so efficient that they can easily meet your needs, whether you need the store of vegetables or deep-freezing of something else.
3.1 Whirlpool Refrigerator Design Features
After discovering that maintaining temperature stability is the core factor for improving refrigerators’ performance, the Whirlpool refrigerator research and development team devoted themselves to developing intelligent temperature control technology to avoid damage to the freshness of fruits and vegetables caused by large temperature differences and unstable temperatures.
Whirlpool refrigerator adopts intelligent temperature control technology to keep the cabinet temperature stable at all times. Built-in multiple sensors can collect data 64 times per second and sense room and ambient temperature changes in real time.
Its self-developed main control board is equipped with the American PI proportional algorithm, which intelligently matches the compressor gear, and can realize rapid temperature change.

4. Mitsubishi
4.1 Mitsubishi Refrigerator Design Features
The instant freezing technology developed by Mitsubishi saves the defrosting process. Different from other manufacturers who usually enhance the refrigeration efficiency by strengthening the compressor, Mitsubishi has developed an exclusive technology using the phenomenon of "supercooling".
Supercooling refers to the state where the temperature of the object has reached below the freezing point but is still not solidified. If the inside and outside of the food are quickly frozen in this state, the resultant ice crystals will be very small and will not easily damage the cells of the food. Therefore, frozen ingredients can be sliced without defrosting, and the original and delicious taste can be preserved.
In addition, all the accessories of the automatic ice maker, including filters and water supply pipes, can be disassembled and washed with water, which is also a unique feature of Mitsubishi. Families needing a large amount of ice can think about this brand.

5. Hitachi
Founded in 1908, Hitachi is a century-old brand. The brand has always provided us with some of the best high-tech appliances. They are known for their high-end features, smart controls, artificial intelligence, and rigidity and reliability.
Refrigerators of this brand have the best temperature and control function, and you will love its cooling performance along with leading features that facilitate modern life.
5.1 Hitachi Refrigerator Design Features
The refrigerators exclusively developed by Hitachi adopt Nano technology, which can decompose ethylene released by vegetables and fruits into carbon dioxide. These carbon dioxide will reduce the respiration of vegetables, thereby reducing the loss of nutrients and water.
By maintaining an atmospheric pressure of about 0.8, the oxidation of food is further inhibited, and the deliciousness of fish and meat can be kept at -1°C close to the freezing point.

6. Panasonic
Panasonic brand refrigerators also have high-end features and smart controls that will make our daily life easier and serve us well.
Like other brands, this refrigerator has a variety of models, including single-door, double-door, and multi-door refrigerators, along with many of the brand's special features.
6.1 Panasonic Refrigerator Design Features
Panasonic has developed the "Rapid Freezing" technology and claims to achieve the same freezing speed as commercial refrigerators. Using this function can improve the taste of cured meat, or directly cool hot meals to reduce the possibility of spoilage at high temperature.
The "soft freezing chamber" (fresh freezing chamber) has a temperature of at -3°C and can slightly freeze the surface of the food, thereby prolonging their freshness period.
The brand's carefulness can also be seen in the structure of the refrigerator, such as relocating the compressor on the top of the refrigerator to maximize the storage space of the fruit and vegetable compartment and the freezer compartment below.
