What is the refrigerant of fluorine-free refrigerator?
The refrigerants of fluorine-free refrigerators are mainly R600a, R- 134a, R-404A, R-4 10A, which belong to environmental protection refrigerants.
There is a label on the nameplate behind the refrigerator. Some freon refrigerants have been eliminated, and there is no such refrigerator product on the market.
The major improvement of fluorine-free refrigerator is that R- 12 Freon is not used at first, but R- 134a is widely used as refrigerant, and the lubricating oil and sealing materials in the system are innovated and advanced production technology is adopted to ensure the refrigeration effect.

The invention of refrigerator solved the problem of food preservation, but because the refrigeration system of ordinary refrigerator uses R- 12 freon as refrigerant, Freon has always been regarded as the chief culprit in destroying the ozone layer of the earth. After freon leaks into the air, it is exposed to ultraviolet rays in the sun, which is prone to chemical reactions, leading to the reduction of ozone and even the destruction of the ozone layer, thus posing a threat to human health and biological growth.
In order to protect the atmospheric environment on which human beings depend, the "fluorine-free" refrigerator is advocated and used. The major improvement of fluorine-free refrigerator is that R- 12 Freon is not used at first, but R- 134a is widely used as refrigerant, and the lubricating oil and sealing materials in the system are innovated and advanced production technology is adopted to ensure the refrigeration effect.
Secondly, the compressor of fluorine-free refrigerator adopts a compressor with different structure from that of ordinary refrigerator, and its working state is also very different. When the fluorine-free refrigerator is running, the low-pressure suction pipe of the compressor is in a negative pressure state, while the pressure of the high-pressure exhaust pipe is higher than that of the ordinary compressor, which will cause the problem of relatively high compressor temperature. However, as long as the heat dissipation of the refrigerator is strengthened during use, the refrigeration effect and service life of the refrigerator will not be affected.
R 12 refrigerant is commonly used in the refrigeration system of ordinary refrigerators. When it leaks into the air and is exposed to the sun, a chemical reaction will occur. It leads to the reduction of ozone, the destruction of atmospheric environment, the disappearance of ozone layer and the formation of holes, which poses a great threat to human health and normal biological growth.
With the release of national regulations on Freon refrigerants, all products using Freon refrigerants in 20 10 are not allowed to be sold. Therefore, many manufacturers have gradually transformed and introduced fluorine-free refrigerators. Most of these refrigerators use R 134a refrigerant or R600a refrigerant instead of R 12 refrigerant, and the main components, sealing materials and lubricating oil of refrigerators are different from ordinary refrigerators.
What is the refrigerant of fluorine-free refrigerator?
Hello! Main R600aR- 134a, R-404A, R-4 10A are marked on the nameplate behind the refrigerator, which are all environmental protection agents. Freon refrigerants such as R 12 have been eliminated, and there is no such refrigerator in the market. 1.R600a Chinese name: isobutane English name: isobutane Chinese name 2:2- methylpropane English name 2:2- methylpropane casNo. : 75-28-5 Molecular formula: C4H 10 Molecular weight: 58. 12 Physical and chemical characteristics Main ingredients: pure appearance and characteristics: colorless. Melting point (℃):- 159.6 boiling point (℃):-1.8 relative density (water = 1): 0.56 relative vapor density (air =1): 2.0/kloc. Health hazard: it has weak stimulation and anesthetic effect. Acute poisoning: mainly manifested as headache, dizziness, lethargy, nausea and drunkenness, and in severe cases, coma may occur. Chronic effects: headache, dizziness, poor sleep and fatigue. Danger of explosion: This product is flammable. Hazard characteristics: combustible gas. When mixed with air, it can form an explosive mixture, which is in danger of burning and explosion when it meets heat sources and open flames. Contact with oxidant and react violently. Its vapor is heavier than air, and it can spread to a considerable distance at a lower place, and it will catch fire when it meets a fire source. 2. The molecular formula is 2. R 134a: CH 2 FCF 3 (tetrafluoroethane), molecular weight: 102.03 boiling point: -26.26℃, freezing point: -96.6℃, critical temperature:10/.1 1.207g/cm 3, liquid specific heat: 25℃, 1.5 1kJ/(kg℃), solubility (in water at 25℃): 0. 15%, critical density: 0.5/. Global warming coefficient (GWP): evaporation potential at boiling point of 0.29: 2 15 kJ/kg Quality index: purity ≥ 99.9%, moisture PPm≤ 0.00 10, acidity PPm≤ 0.0000 1, and evaporation residue ppm ≤ 0.0/. R 134a is extremely low in toxicity and nonflammable in air. The safety category is A 1, which is a very safe refrigerant. R 134a has good chemical stability, but its water solubility is higher than R22, which is not good for refrigeration system. Even if there is a small amount of water, under the action of lubricating oil, acid, carbon dioxide or carbon monoxide will be produced, which will corrode metals or produce "copper plating", so R 134a requires higher drying and cleaning of the system. R 134a has no chemical reaction with steel, iron, copper, aluminum and other metals, and only has a slight effect on zinc. R 134a is one of the main refrigerants recognized internationally to replace CFC- 12. It is often used in automobile air conditioning, commercial and industrial refrigeration systems, as a foaming agent in the production of hard plastic insulation materials, and can also be used to prepare other mixed refrigerants, such as R 404a and R 407c. 3. Physical and chemical characteristics of R-404A refrigerant: R404A is a chlorine-free non-boiling mixed refrigerant, which is colorless gas at normal temperature and pressure, and is a compressed liquefied gas stored in steel cylinders. Its ODP is 0, so R404A is an environmentally friendly refrigerant that does not destroy the atmospheric ozone layer. Main uses: R404A is mainly used to replace R22 and R502. It is clean, low toxic, non-flammable and has good refrigeration effect, and is widely used in medium and low temperature refrigeration systems. 4. Physical and chemical characteristics of R-4 10A refrigerant: At normal temperature and pressure, R-410A is a chlorine-free non-boiling mixed refrigerant of fluorinated alkanes, a colorless gas, and a compressed liquefied gas stored in a steel cylinder. Its ODP is 0, so R4 10A is an environmentally friendly refrigerant that does not destroy the atmospheric ozone layer.

No matter whether the system leaks or not, the concentration of isobutane in all areas of ignition electrical devices cannot reach the explosion limit. Because isobutane is heavier than air, it is necessary to ensure that the maintenance site is well ventilated. When pouring refrigerant, in order to avoid the possibility of static electricity and sparks, it is required that all equipment must be reliably grounded, and all wiring must be firm and must not be connected wrong.
A. First, check whether there is a fire source in the surrounding environment and maintain good ventilation;
B. Prepare special equipment and accessories for maintenance;
C. check the safety of maintenance equipment and power supply;

Hello! Lyon, which used R 1 1 and R 12 as foaming refrigerants in the forecabin, leaked into the air, and reacted chemically after being irradiated by ultraviolet rays, destroying the ozone layer and threatening human health and biological growth. In order to protect the atmospheric environment on which human beings depend, a substitute R600a for freon was found. This kind of refrigerant refrigerator is faster and more energy-saving. I'm happy to help you!
What is the refrigerator refrigerant?
Commonly known as refrigerant, it absorbs heat to realize working medium in refrigeration cycle. The main chemical components are Freon R 12, R22, etc. ), which is the refrigerant commonly used in refrigeration appliances in the early stage. This kind of refrigerant has good stability, but it was gradually eliminated only because it polluted the atmosphere. At present, the mixed refrigerant of R 134A is common in the society. At present, the mixed refrigerant should not be considered as a fluorine-free refrigerant, because it is a mixture of R22 and R502, which itself contains fluorine, and it is only a transitional product. At present, R600A, the most widely used refrigerant in household refrigerators and freezers, is the refrigerant that can approach the refrigeration performance of R 12 at present, and its consumption is quite economical, which is only13 of R 12. Although there are some problems, its effect is still relatively good.
