What are the specific classifications of common refrigerators in our daily life?

There are many types of refrigerators. The main types can be divided into the following categories:

1.Compression Chiller: This type of chiller provides mechanical energy through an electric motor.

The refrigeration system is acted on by means of a compressor. The refrigeration system uses a low boiling point refrigerant.

It is made by absorbing the heat of evaporation at the time of evaporation. The utility model discloses a long service life, and is convenient to use. Currently, 91 to 95% of the world's refrigerators fall into this category. At present, commonly used refrigerators use a type called freon.

The substance acts as a "porter" of heat, bringing the "heat" in the refrigerator to the outside of the refrigerator.

2.Absorption refrigerators: This type of refrigerator can use a heat source (such as gas, kerosene, electricity, etc.) as power. The purpose of refrigeration is to use ammonia and hydrogen to mix solutions.

Achieved in the process of continuous absorption diffusion. Its disadvantages are low efficiency and slow cooling, and it has been gradually phased out.

3.Semiconductor coolers.

It is a type of direct current that is applied to PN semiconductors.

and create a Peltier effect at the node.

to achieve refrigeration.

4.Chemical refrigerator: A refrigerator that uses strong heat absorption to achieve a cooling effect when certain chemicals are dissolved in water.

5.Electromagnetic vibrating refrigerator: A refrigerator that uses an electromagnetic vibrator as its own power to drive a compressor. Its principle and structure are basically the same as those of a compression refrigerator.

6.Solar refrigerators: Refrigerators that utilize solar energy as a cooling energy source.

7.Adiabatic demagnetization refrigerator.

8.Radiant refrigeration refrigerators.

9.Solid refrigerated refrigerators.

10.We know that any substance releases heat after liquefaction and absorbs heat during vaporization, which is the most common physical phenomenon. Air conditioners and refrigerators use this principle to liquefy the refrigerant to release heat, which is then allowed to evaporate to absorb the heat.

The heat released by liquefaction and the heat absorbed by evaporation cannot be in the same place, otherwise there will be no effect. Therefore, the air conditioner has an outdoor unit with the main functions such as heat dissipation, and the radiator of the refrigerator is outside the refrigerator.

11.We know that when the pressure is at a critical temperature.

When a certain value is reached, the gaseous substance liquefies. The so-called critical temperature is higher than this. It cannot be liquefied no matter how high the pressure is used.

Gasification occurs when the temperature is higher than the boiling point of a gaseous material at a certain pressure. During gasification, heat is absorbed, and the absorbed heat is obtained from the environment, resulting in refrigeration.

The gaseous substance used to achieve refrigeration is the refrigerant. As a refrigerant, the substance is usually a gas at room temperature for easy evaporation, and the critical temperature cannot be too low, otherwise it is not easy to liquefy during compression. It also requires to be non-toxic and odorless.

Refrigerators, freezers, direct cooling, intercooling, and are also divided into double doors and multiple doors, these types are classified according to their appearance and their effects.

Compression refrigerators, absorption refrigerators, single-door refrigerators, double-door refrigerators, smart refrigerators, these are basically common refrigerators.

The classification of refrigerators includes, single-door refrigerators, double-door refrigerators, three-door refrigerators, energy-saving refrigerators, and smart refrigerators, which are the specific classifications of refrigerators.

The common refrigerators in our lives, if divided according to the type, have single door, double door, triple door, double door folio, three-door folio, cross folio and multi-door folio; If it is divided according to the refrigeration method, there are direct cooling, air-cooling, and air-cooled mixed type; If it is divided according to the cycle mode, there are single cycle and double cycle; According to the energy efficiency level, it is divided into 1-5 levels. For example, Siemens KA92NV90TIThis refrigerator is a bi-side, 610L large-capacity refrigerator.

Now that the standard of living has improved, meat and vegetables are no longer simply stored in the refrigerator, and drinks, children's supplementary food, nutritional and health products, etc. also need to be refrigerated.

Hello, refrigerators belong to the category of electrical appliances and are household appliances.

A refrigerator is a kind of refrigeration equipment that maintains a constant low temperature, and it is also a civilian product that keeps food or other items in a constant low temperature state. Inside the box there is a compressor, a cabinet or box for ice making for icing, and a storage box with a refrigeration unit. The volume of a household refrigerator is usually 20 500 liters.

When choosing a refrigerator, you need to pay attention to its type, style, and brand. What are the types of refrigerators? PChouse will take you to find out.

1. Divided by use.

1. Food refrigeration refrigerator.

It is suitable for food freezing, the box temperature is below -18, and it is used for frozen meat and fish refrigeration.

2. Food refrigerated refrigerator.

Store food that does not need to be frozen, and the temperature range of the box is 0 10.

3. Refrigerated refrigerator.

It is suitable for frozen food and storage of frozen food, the temperature of the box is -18 or below, it has a freezer compartment, and the outer surface of the box is attached with a star symbol to indicate the temperature characteristics of the refrigerator.

Second, according to the door structure.

1. Single-door smart refrigerator.

Single-door smart refrigerator refers to a smart refrigerator product with only one door, and its cooling method is to rely on the internal evaporator for low temperature cooling, so that the air in the smart refrigerator forms a natural convection, the **range of this type of smart refrigerator is about 400-2000 yuan, and there may be individual high-performance products ** will be slightly more expensive, may reach about 3000 yuan.

2. Multi-door smart refrigerator.

Multi-door smart refrigerator is a type of smart refrigerator that has only appeared in recent years, and it is also a popular trend of smart refrigerators, which divides the freezer area and refrigeration area into multiple doors and multiple temperatures, which is convenient for storing different foods, but this type of product has a large volume and is expensive, and the range of this type of smart refrigerator is about 4000-20000 yuan.
