Air-cooled refrigerators will usher in a golden period of development

In 2010, the refrigerator industry showed a clear trend of high-end development. Under this trend, refrigerator technology has been continuously upgraded, and air-cooled refrigerators have become a hot spot in the market. According to the monitoring data from Zhongyi Kang, from January to November 2010, the sales of air-cooled refrigerators increased by 56.05% year-on-year, and retail sales increased by 46.94% year-on-year. On the one hand, mainstream enterprises in the industry actively promote air-cooled refrigerators. On the other hand, they are also working hard to upgrade air-cooled technologies and push the refrigerators toward an era of no frost, energy saving, and preservation.

Currently, frost-free refrigerators on the market use air-cooled technology, while traditional refrigerators use direct-cooling technology. The evaporator of the air-cooled refrigerator is not in direct contact with the food. The evaporator can heat up the evaporator for a short time through the heating system, and the refrigeration can be resumed immediately after the defrosting. The refrigerator will not have frost.

The conventional freezer freezer compartment is directly surrounded by an evaporator or has an evaporator in the freezer compartment. In addition, an evaporator is provided in the upper part of the freezer compartment, and the evaporator directly draws heat. The advantage of the direct-freezer is its low power consumption, low noise, low price, and refrigerated food preservation, but its poor temperature uniformity requires manual defrosting.

The air-cooled refrigerator adopts fan forced heat exchange, the cooling capacity is relatively large, the cooling speed is fast, the temperature inside the box is even, and it has an automatic defrosting function, and no manual defrosting is required. However, the fin evaporator fans used in air-cooled refrigerators have relatively large volume of parts such as forced heat exchange systems and air duct systems, which results in relatively low capacity utilization of the refrigerators. Therefore, air-cooled technologies are usually carried in large-capacity refrigerators. Above (230 liters or more). In addition, air-cooled refrigerators have relatively high noise, high energy consumption, and relatively poor moisturizing effects. It was precisely because of this that it was popular in the 1980s and then quickly withdrew from the market. The mainstream product type on the market today is a direct-freezer refrigerator. However, with the rapid growth in sales of three-door, multi-door refrigerators and door-to-door refrigerators in recent years, air-cooled refrigerators have also taken express trains and their market share has rapidly increased.

Industry analysts pointed out that from the perspective of users' needs, the trend of accelerating the popularity of air-cooled refrigerators is certain. Now that the pace of life is accelerating, consumers have fewer food purchases, but the volume has increased. Many times it is focused on shopping once a week. This requires better refrigerator preservation, greater capacity, and faster cooling. The characteristics of air-cooled refrigerators exactly meet these needs.

For the characteristics of air-cooled and direct-cooled technology, some companies have introduced refrigerators equipped with both wind and direct cooling technology. They use direct cooling in the cold room to avoid food drying and use air-cooling in the freezer to avoid frosting in the refrigerator. In addition, with a number of technologies such as frequency conversion and moisture retention, the technical shortcomings of air-cooled refrigerators are constantly being made up.

In addition, the air-cooling technology is gradually being carried on small-volume refrigerators, and air-cooled two-door refrigerators have appeared on the market. It is expected that the golden period for the development of air-cooled refrigerators will usher in the next 3-5 years.
