Is the refrigerant good? Freon or new refrigerant. Which refrigerant is the best for home air-conditioning?

Refrigerant is an important medium for air-conditioning and refrigeration, also called refrigerant and refrigerant. In summer, when many people use air conditioners, they find that there is no cooling effect when there is less refrigerant in air conditioners. Want to buy refrigerant, then, is the refrigerant good for Freon or new refrigerant? What is the best refrigerant for air conditioning at home? Freon and the new refrigerant are both a kind of refrigerant. What is the difference between the two, let's follow the editor to understand.

Is the refrigerant good for Freon or the new refrigerant?

The new refrigerant is a new type of refrigerant, which will not affect the ozone layer in the application. At the same time, this kind of refrigerant is generally composed of carbon, hydrogen, fluorine and other elements because it is relatively stable and non-toxic. However, Freon will destroy the ozone layer in the atmosphere during the application process. Therefore, many air conditioners and other refrigeration equipment are slowly leaving the application of Freon.

Freon characteristics classification:

Freon, also known as Freon, the name comes from English Freon, it is a refrigerant trademark registered by DuPont of the United States . In China, there are differences in the definition of Freon. It is generally defined as the general term for halogenated substances of saturated hydrocarbons (mainly methane, ethane and propane). According to this definition, Freon can be divided into four categories: CFC, HCFC, and HFC. Freon is only one type of refrigerant, and refrigerants can be divided into three categories: high temperature (low pressure) refrigerant, medium temperature (medium pressure) refrigerant and low temperature (high pressure) refrigerant.

1. Freon refrigerants commonly used include R12, R22, R502 and R1341a, because other types of refrigerants are now deactivated or banned.

2. Freon 12 (CF2CL2, R12): It is one of the most widely used Freon refrigerants, mainly for medium and small food warehouses, household refrigerators, and water and road refrigerated transportation. It is widely used in refrigeration equipment.

3. Freon 22 (CHF2CL, R22): It is one of the most widely used Freon refrigerants, mainly used in household air conditioners and low-temperature refrigerators.

4. Freon 502 (R502): R502 is an azeotropic solution made by mixing R12 and R22 at the percentages of 51.2% and 48.8%.

5. Freon 134a (C2H2F4, R134a): It is a relatively new type of refrigerant with an evaporation temperature of -26.5°C.

What is the new refrigerant?

The new refrigerant is a new environmentally friendly refrigerant used to solve the harm of the previously used refrigerant Freon to the atmosphere. There is no harm to the atmosphere without fluorine. r410a, R134a, and R407C are commonly used. And now the main one is R410A. Due to the advantages of R410A new refrigerant in product use characteristics, it will become the future development trend of air-conditioning refrigerants.

R410A new refrigerant: R410A, is a mixed refrigerant, it is a mixture of R32 (difluoromethane) and R125 (pentafluoroethane), its advantage is that it can be used according to specific requirements , Considering various properties, such as flammability, capacity, exhaust temperature and efficiency, and tailoring a refrigerant. R410A is colorless, non-turbid, volatile, boiling point -51.6℃, freezing point -155℃; its main features are: (1) It does not destroy the ozone layer. Its molecular formula does not contain chlorine, so its ozone depletion potential (ODP) is 0. The global warming potential (GWP) is less than 0.2.

(2) Very low toxicity. The allowable concentration is 1000 ppm, the same as R22.

(3) Non-flammable. The flammable polarity in the air is zero.

(4) High chemical and thermal stability.

(5) Water solubility is almost the same as R22.

(6) is a mixed refrigerant, composed of two refrigerants.

(7) It is not compatible with mineral oil or alkylbenzene oil. (Compatible with POE [ester lubricating oil] and PVE [ether lubricating oil]).

The above is an introduction about whether the refrigerant is Freon or a new refrigerant, and what refrigerant is best for home air-conditioning. So when everyone chooses refrigerants, they still choose new refrigerants, which are more environmentally friendly.
