In fact, there are many categories of freezers, and the classification is more complicated than that of refrigerators, and it needs to be classified from multiple angles.

By use

Household refrigerators: Home refrigerators generally pay attention to appearance, and the volume is generally less than 200 liters. There are horizontal and vertical types, and they store fruits and vegetables, instant noodles, meat and seafood.

Commercial freezer: The volume of commercial freezer is generally more than 200 liters, and it is widely used. In commercial business places such as shopping malls, supermarkets, cold drink stores, frozen goods stores, hotels and restaurants, the temperature also varies from refrigeration to freezing. Commercial use itself is subdivided into many , This article focuses on household refrigerators, and commercial refrigerators are discussed separately.

2. According to the cooling method

Direct cooling freezer: The main feature of the direct cooling freezer is the frost in the cabinet, which needs to be cleaned regularly, but its advantages such as affordable price, freezing and not air-drying, etc.

Air-cooled frost-free freezer: The internal structure of the air-cooled freezer is relatively complex, the cold air in the box is forced to convection, the temperature uniformity is good, and manual defrosting is not required, but the price is relatively more expensive.

3. Divided by greenhouse

Double temperature cabinet: The double temperature freezer has two greenhouses, one is refrigerating and the other is freezing, and the middle is separated, which can be comparable to the function of a refrigerator and is easy to use.

Single temperature cabinet: Single temperature freezer has only one greenhouse, one temperature, or refrigerated or frozen. Therefore, a single-temperature freezer can only choose one temperature at a time, but now many single-temperature freezers have a storage-freezing conversion function, which can be used as a freezer or as a refrigerator.

4. According to the temperature range

Refrigerator: The model number starts with BC. The temperature in the refrigerator is generally in the range of 0 to 10°C, which can be used to store beverages, eggs, dairy products, fruits, vegetables, etc.

Freezer: The model number starts with BD. The temperature inside the freezer is usually below -18°C, which can be used to freeze food and store frozen food or other items for a long time, such as meat and seafood.

Refrigerator and freezer dual temperature cabinet: The model starts with BCD, the body has two separate compartments, and there are two independently opening doors. One of them is a refrigerating room, and the other is a freezer room, which are used to store refrigerated and frozen food respectively, and generally have a horizontal top door structure.

Refrigerator-freezer conversion cabinet: The model starts with BC/BD, has only one compartment, the temperature can be from -24°C to 8°C, and can be used as a refrigerator or freezer.

5. According to the way of opening the door

Horizontal freezer: The horizontal freezer is the earliest form of freezer, and the door body opens upwards. Its advantage is that it has a large volume and can store large items; its disadvantage is that it will be difficult and inconvenient to rummage when there are too many kinds of items.

Vertical freezer: The door of the vertical freezer opens to the side, like a refrigerator; its advantage is that it can be stored in categories, and it is convenient to take items; the disadvantage is that when the item is large, it cannot be put into the vertical freezer. The vertical freezer has a glass transparent door, which is used for food and beverage freezers in supermarkets and convenience stores.

Household vertical refrigerators have recently developed in my country. Because of their small footprint and convenient storage, they are popular with consumers and develop rapidly. In Europe and the United States, they have developed for many years, and their sales have surpassed horizontal refrigerators.
