A long history has made it a leader in the air-cooled refrigerator

Panasonic's corporate history has been nearly 100 years, and in the field of refrigerators, Panasonic has 60 years of history, its first refrigerator model is NR-351, produced in 1953. The NR-351 has a great historical significance. The compact compressor adopts a high-level production process, with high-precision processing technology and carefully selected materials, and the technology is superior to others. In addition, Panasonic's “Crown Logo” was affixed to the top of the door, giving people a feeling of luxury and was appreciated by many high-income families at the time.

Panasonic's first refrigerator NR-351

In 1972, Panasonic's first two-door air-cooled frost-free refrigerator was launched. That is to say, so far, Panasonic's air-cooled, frost-free refrigerator has been around for 41 years. Panasonic is the originator of air-cooled technology. Fast, uniform temperature, and no defrosting.

What is an air-cooled refrigerator?

An air-cooled refrigerator, also called a frost-free refrigerator, is different from a conventional direct-cooling refrigerator in that it is a type of refrigerator that employs a continuous cooling cycle of air. The working principle is that the evaporator is placed in the interlayer between the freezing chamber and the refrigerating chamber or in the upper portion of the interior of the chamber. A small fan is used to force air convection in the refrigerator from the tuyere to achieve the purpose of cooling. The biggest advantage of this type of refrigerator is that it does not require manual defrosting. The hidden evaporator will automate the cream. At the same time, the temperature in the refrigerator is relatively even and there will be no lower temperature in the lower and rear sides of the refrigerator as in the direct-freezer.

Panasonic air-cooled refrigerators have innovative hidden side air outlets. The air-conditioning system performs a three-dimensional cycle around the food and does not directly blow foods to cause food to dry. Compared with the direct-freezer refrigerator, the air-cooled refrigerator uses the operation of the fan to bring the cold air to all corners, so that the internal temperature of the refrigerator is more uniform and is conducive to food preservation.

Looking at the refrigerators currently on the market, air-cooled refrigerators are basically positioned in high-end products, and it is almost impossible to buy frost-free refrigerators within 3,000 yuan. However, with the popularization of technology, it is expected that air-cooled refrigerators may be in the future. Several years have ushered in the prime time of development.

From the user's needs, air-cooled refrigerators will certainly accelerate the popularity. The rhythm of modern life is accelerating, and the number of food purchases by consumers has decreased, but the quantity has increased. In many cases, shopping is concentrated once a week. This requires better refrigerator preservation, greater capacity, faster cooling speed, and the characteristics of air-cooled refrigerators. Meet these needs. From a technical point of view, if the capacity of the refrigerator is greater than 300 liters, the air-cooled and frost-free type is generally used for the refrigeration method, and the refrigeration and fresh-keeping effect can be significantly improved.

Air-cooled refrigerators do not require manual defrosting

As an air-cooled company whose originator and pursuing technology, Panasonic is actively promoting air-cooled refrigerators and is also committed to upgrading air-cooled technology to promote the era of frost-free, energy-saving and preservation refrigerators.

Panasonic new generation of air-cooled refrigerator more uniform temperature

Panasonic recently introduced a number of new air-cooled, frost-free refrigerators. Unlike previous air-cooled technologies, Panasonic's new air-cooled technology uses multi-channel three-dimensional air supply. Soft wind does not directly affect fruits and vegetables, reducing the internal temperature fluctuations of refrigerators, and cooling. Frost-free and fresh-keeping effects have been upgraded.

Compressors and energy-saving technologies

Panasonic has always been an industry leader in terms of technology. Compressors also have strong strengths. At present, refrigerator compressors produced by Panasonic Wanbao, Panasonic Wuxi, or Panasonic Singapore are more common in China. Generally, they are not indicated. Panasonic refrigerators imported from the compressor are all used in Panasonic Wanbao or Wuxi Panasonic products. Some refrigerators such as Siemens also use Panasonic compressors.

In the high-end products, Matsushita refrigerators use a top-mounted imported DC inverter compressor, which transfers the traditional bottom compressor to the top of the refrigerating chamber. The capacity of the freezer compartment is significantly expanded, and the flat air duct design increases the internal depth and improves the Use the volume. Imported Panasonic DC inverter compressor, more energy-efficient, more silent.

At the end of 2012, Panasonic's ECONAVI energy-saving navigation refrigerators came to China. Panasonic made full use of the ECONAVI technology in its localization design in order to achieve energy-saving appliances that are more suitable for China. Panasonic ECONAVI energy-saving navigation technology has made changes in the traditional energy-saving technology, which can save considerable power consumption. Through technical means to change the way people save energy through subjective efforts, better results can be achieved. ECONAVI technology is not only used in refrigerators, but also in washing machines, air conditioners, and air purifiers.

ECONAVI refrigerator with energy-saving navigation technology

Panasonic ECONAVI energy-saving navigation technology, automatic monitoring with advanced sensors and control systems, adjust the refrigerator running status. The brightness sensor senses the intensity of light in the room. At night, for example, people start to rest. When the room brightness is low, the refrigerator will automatically reduce the speed of the compressor. Save energy. The door switch sensor will record and learn the user's door opening frequency and time period. By learning the user's usage habits for a period of time, the refrigerator will automatically increase the operating frequency of the compressor during frequent opening hours, such as cooking time. During periods of infrequent use, such as going out to work, on business trips, and vacations, the company automatically enters an energy-saving state and eliminates waste of electrical energy. In summer and winter, the indoor temperature is different, and the room temperature sensor will sense the room temperature change and automatically adjust the compressor operating frequency to maintain the best cooling effect. When you open and close the door and put in and take out food, the temperature in the refrigerator will change. The temperature sensor inside the refrigerator will monitor these temperature changes in the refrigerator and automatically adjust the compressor operating frequency to achieve the best operation.

ECONAVI energy-saving navigation technology

The greatest function of ECONAVI's function is to memorize, analyze, and predict lifestyles based on the usage of each family, thus saving energy and saving energy for each family. With the application of ECONAVI energy-saving navigation technology, Panasonic refrigerators will be more energy-efficient and temperature control will be more accurate.

Editor's summary: China's refrigerator market is still full of challenges while it has great potential. As a leader in refrigerators, especially in terms of air-cooled and frost-free, Panasonic can ride the wind and waves to win the market. Perhaps this result requires us to wait patiently. .
