Among Japanese refrigerator brands, Panasonic is the most favored by Chinese consumers and has the most abundant online and offline purchase channels. In Japan, Panasonic is a perennial winner in the refrigerator market, ranking first in the market for many years. Panasonic's main advantage lies in its mature compressor technology, and Panasonic is the only refrigerator brand that can independently produce compressors on a large scale.
 
In the Chinese market, the share of direct-cooled refrigerators and air-cooled refrigerators is evenly divided, and all Japanese brands use air-cooled technology and inverter compressors, both of which are extremely mature. As early as 1972, Panasonic launched the world's first air-cooled refrigerator, which replaced the slow conduction of cold air in the past through air convection heat exchange. Air-cooled refrigerators do not need to be defrosted, refrigerate quickly, and almost all mid-to-high-end refrigerators today have air-cooling technology.
 
Compressor technology
 
The compressor of the domestic Panasonic refrigerator is mostly manufactured by Panasonic Wuxi Company, the technology comes from Japan, and its inverter compressor is the round-trip compressor with the highest utilization rate of electric energy at present, and the mature process reduces the energy loss caused by the friction of various parts and effectively reduces the electricity consumption. Some of the products that indicate "imported compressors" are actually made in Malaysia, and the technology is the same as that in China. The refrigerator marked "imported from Japan" is produced in Japan, and the materials and design process of its crankshaft connecting rod are further improved, so that the refrigerator can be controlled as a whole in the national level 1 energy efficiency. The daily power consumption of a 600-liter large-capacity refrigerator can also be controlled at about 1 kWh.
 
The self-production and self-use of the compressor is a great advantage of Panasonic, and the refrigerator design has a higher degree of freedom, and the compressor can be optimized to match the refrigerator, rather than the refrigerator design accommodating the compressor. Although refrigerator brands such as Bosch and Siemens also use Panasonic Wuxi compressors, they can only design refrigerator pipelines according to the compressor situation, which is slightly inferior to Panasonic.
 
The overhead compressor is a unique design of Panasonic refrigerators, moving most brands of compressors that are placed below to the top. This design can expand the space of the lower drawer of the refrigerator, effectively use the top space of the refrigerator that is difficult to reach by both hands, and optimize the efficiency of space utilization, and most mid-to-high-end Panasonic refrigerators adopt the overhead design. Behind this seemingly simple transposition design, the technical difficulty is extremely high. With the exception of Panasonic, all other brands do not have this design to avoid poor oil return after the lubricating oil is thrown out. Panasonic has put aside the traditional gravity oil return device and designed a separate oil separation system to get rid of the constraints of position and make judgments.
 
Micro-freezing preservation technology
 
Micro-freezing technology is Panasonic's main preservation technology. Meat is stored at -3°C without thawing, avoiding the loss of nutrients and taste caused by cryogenic freezing. This is also known as soft freezing or micro-freezing technology, in fact, it can be achieved in the variable temperature zone of most brands, and there is no technical difficulty and cleverness.
 
However, this storage concept has great practical value in daily life, and everyone must encounter a dilemma when facing frozen meat in the past, whether to wait for slow thawing to retain nutrients, or to sacrifice nutrients to thaw quickly? Micro-freezing, on the other hand, has the best of both worlds, eliminating the need to thaw and preserving nutrients and flavor while taking and cutting. Of course, this method of preservation shortens the shelf life of the meat to 15 days, and the ingredients need to be prepared as soon as possible within a week. All Panasonic three-door refrigerators use this micro-freeze preservation technology, but it is difficult to achieve this function in double-door refrigerators or side-by-side refrigerators.
 
Three-door refrigerator with precise temperature control
 
Three-door refrigerators are divided into refrigerated area, frozen area and variable temperature area, and the three-zone capacity ratio is roughly 4:2:1. Panasonic, on the other hand, has set the temperature control range of this area at -3 °C to 4 °C, narrowing the range and making the temperature control more precise and refined.
 
Panasonic three-door refrigerator has many styles, the capacity can be freely selected between 255 liters, 280 liters, 318 liters, and 360 liters, and the panel material is PCM color-coated board, VCM laminated board, stainless steel, tempered glass four kinds of panels, wear resistance and easy cleaning are improved in turn, and directly affect the appearance of the rendering effect. The refrigerator technology is mature, and when you buy a refrigerator, you can choose the appearance first, and then look at the function. Some products are equipped with silver ion technology. Inside the air-cooled refrigerator, bacteria will inevitably float, and odor molecules will be mixed in the circulating air, affecting the quality of food. The silver ion filter screen is equivalent to erecting a filtration protection wall, which inhibits bacteria and catalyzes odor decomposition at the same time. The refrigerator with this function is about 300 yuan higher than the regular model.
 
Finely partitioned Japanese multi-door
 
Japanese multi-door refrigerators can be called the gospel of "finishing control". This type of refrigerator is actually a branch of the French refrigerator, in addition to the traditional fresh-keeping, freezing, vegetables and fruits area, the middle layer has added an additional quick-freezing area and an ice-making area. There are also small spaces such as hidden drawers and separate wet and dry storage boxes, which are enough to classify food, facilitate storage and classification, and reduce food mixing.
 
Japanese families use to freeze meat, seafood, and other ingredients quickly in the quick-frozen area before moving them to the freezing area below. The freezing speed of the blast freeze zone is fast, which can quickly freeze food cells and reduce nutrient loss. Japanese people like to drink ice water, and Panasonic's "80-minute one-button quick ice" function is quite popular. However, for Chinese families who are accustomed to drinking warm water, the specialized ice-making function is relatively weak most of the time, and domestic manufacturers such as Haier can often remove it even if they have an ice-making area. A small number of Panasonic's products, such as the EE50TP1, also take this situation into account, eliminating the middle ice-making drawer, expanding the capacity of the quick-freezing area, and the price is lower than that of the model without ice-making function, which is actually a more suitable choice for domestic families.
 
The vast majority of Japanese families are accustomed to using Japanese multi-door refrigerators, and such refrigerators are also the main battlefield of the five major Japanese refrigerator brands of Panasonic, Sharp, Hitachi, Toshiba and Mitsubishi Electric. Panasonic's Japanese multi-door refrigerator products are sold at about 10,000 yuan in China, with overhead compressors, silver ion sterilization, micro-freezing technology and other advantageous technologies, steady and steady. In comparison, Hitachi refrigerators are designed to be more generous, with more advantages in electric door opening, and the preservation of vegetables and fruits, because of imports, the price is expensive.
 
Japanese multi-door refrigerators are meticulously planned, but they are not suitable for all families. This kind of established planning is more suitable for families with more fruits and vegetables and faster food renewal. Families who need to freeze large quantities of seafood, whole chicken, or beef and mutton rolls for a long time will feel that the freezer area is too small.
 
Flagship refrigerator
 
Panasonic's flagship products are all imported from Japan, and have been sold on e-commerce platforms, with a price of about 30,000 yuan. The most impressive thing about the flagship refrigerator is its mirrored glass appearance, which is clear and bright, which can be called a home mirror with a refrigeration function, which greatly increases the interior decoration. Panasonic's flagship refrigerator focuses on intelligent upgrades, enriching Panasonic's cutting-edge technologies such as ECONAVI energy-saving navigation, Nanoe X sterilization, free humidity control of the best room, and APP management. Panasonic launched new flagship products with these features at the AWE exhibition in China in 2018, including the French refrigerator W621TF and the Japanese refrigerator F681WX.
 
The function of the Nanoe X is derived from Panasonic's air purifier, which is an upgrade of the original passive silver ion antibacterial function. By generating trillions of hydroxide ions per second, the refrigerator is actively sterilized. The test results of the China Household Electrical Appliances Testing Institute showed that the sterilization rate of E. coli was more than 90%. In addition, hydroxyl ions can also decompose odor components such as trimethylamine and sulfide to purify the air in the refrigerator. The material room can be switched between dry, low humidity and normal mode, which can not only store medicinal herbs, tea, mountain delicacies, but also grains.
 
After-sales
 
Panasonic three-door refrigerator price 3000-6000 yuan, cost-effective, is suitable for most families of high-quality choice, Japanese multi-door function subdivision, the price of nearly 10,000 yuan, is the pursuit of quality of high-end choice.
 
Panasonic refrigerators have an after-sales period of 1 year for the whole machine, 3 years for the main components, and 5 years for the refrigeration system, which is one of the brands with the longest warranty in the industry. However, Panasonic mid-to-high-end refrigerators have consumer feedback that their high-frequency noise is obvious, in fact, because the top compressor is closer to the human ear, and the jitter of the center of gravity will also bring greater vibration and sound. It is recommended that consumers who are sensitive to sound go to a physical store to experience it before making a purchase.
