    The new refrigerant is a new environmentally friendly refrigerant used to solve the harm of the previous refrigerant freon to the atmosphere, which does not contain fluorine and is not harmful to the atmosphere, and is now commonly used R410A, R134A, R407C. The main thing used now is a mixed refrigerant, which is a mixture of R32 (difluoromethane) and R125 (pentafluoroethane), and its advantage is that it can be tailored to a refrigerant according to the specific use requirements, considering various properties, such as flammability, capacity, exhaust temperature and efficiency. R410A is colorless in appearance, not turbid, volatile, boiling point, freezing point -155.

    Its main features are:

    1) Does not destroy the ozone layer. It does not contain chlorine in its molecular formula, so its ozone depletion potential (ODP) is 0. The global warming potential (GWP) is less than.

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

    3) Non-flammable. The flammable polarity in the air is 0.

    4) High chemical and thermal stability.

    5) Water solubility is almost the same as R22.

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

    7) Not miscible with mineral oil or alkylbenzene oil. (Soluble with POE [ester lubricating oil], PVE [ether lubricating oil])

    RefrigerantIt is also known as refrigerant, refrigerantRefrigerantsIt is a medium substance used to complete the energy conversion in various heat engines.

    These substances typically increase their power through reversible phase transitions, such as gas-liquid phase transitions. Such as steam in a steam engine, refrigerant in a refrigerator, and so on. Steam engines in general.

    While working, the thermal energy of the steam is released and converted into mechanical energy.

    to generate the driving force; The refrigerant of the refrigerator is used to transmit the heat from the low temperature to the high virtual temperature barrier.

    Some halogenated hydrocarbons (especially chlorofluorocarbons) are the most common working medium in traditional industry and life, but they are now gradually being phased out due to their poor condition and the hole in the ozone layer. Other widely used working media are ammonia and sulfur dioxide.

    and non-halogenated hydrocarbons (e.g., methane.

    History

    In 1805 Evans (the original author) proposed the idea of using volatile fluids in a closed loop to freeze water into ice.

    He described such a system in which ether is evaporated under vacuum and steam is pumped to a water-cooled heat exchanger, where it is condensed and used again. In 1834, Perkins first developed and patented the vapor compression refrigeration cycle. Diethyl ether (ethyl ether) is used as a refrigerant in the vapor compression refrigeration plants he designed.

    The new refrigerant means R410A refrigerant, which does not destroy the ozone layer compared with the previous refrigerant R22, and the working pressure is about twice that of ordinary R22 air conditioners, and the refrigeration (warm) efficiency is high.

    The new refrigerant is composed of two quasi-azeotropic mixtures, R32 and R125, 50% each, mainly composed of hydrogen, fluorine and carbon elements (expressed as HFC), which has the characteristics of stability, non-toxicity and superior performance.

    At present, the new refrigerant of air conditioning usually refers to R410A, compared with R22, which is widely used now, because there are no chloride ions in its composition, it has less damage to the ozone layer of the atmosphere and can slow down the greenhouse effect of the atmosphere, but R410A is not absolutely not destructive to the ozone layer, and will eventually be replaced by R290 R22.

    The new environmentally friendly refrigerant is R410. Environmentally friendly, no impact on the atmosphere. But it's expensive. R407C, R22, have different degrees of damage to the atmosphere, so it is not recommended to use them now. The effect is basically the same.

    Refers to R410A refrigerant, R410A: is a new type of environmentally friendly refrigerant, does not destroy the ozone layer, the working pressure is about twice that of ordinary R22 air conditioners, and the refrigeration (warm) efficiency is high. R410A new refrigerant is composed of two quasi-azeotropic mixtures, R32 and R125, 50% each, mainly composed of hydrogen, fluorine and carbon elements (expressed as HFC), which has the characteristics of stability, non-toxicity and superior performance.

    At the same time, because it does not contain chlorine, it will not react with ozone and will not destroy the ozone layer. In addition, the performance of air conditioners with new refrigerants will also be improved. R410A was internationally recognized as the most suitable refrigerant to replace R22, and has been popularized in Europe, America, Japan and other countries.

    Global trends and outlook for R410A replacement in key international markets, usage status and international market entry dynamics.

    Now many Japanese and domestic air conditioners are using it, although R32 is more efficient than R410A refrigeration, but he is not safe, many air conditioning maintenance masters refuse to repair R32 refrigerant air conditioners.

    By 2020, the production and use of R22, a non-environmentally friendly refrigerant, will be banned due to its damage to the ozone layer. The environmentally friendly refrigerant R410A is temporarily used in inverter air conditioning, but due to the large heat production, it will cause the greenhouse effect, and now developed countries are also in the category of non-environmental protection refrigerant, so the new refrigerant used now is mainly R32 and R290, of which R32 is widely used, many air conditioners are now using this refrigerant, Gree and Midea are the earliest domestic brands used, but although this new refrigerant will not cause ozone layer destruction and serious greenhouse effect, But there is a hidden danger that it will occur in the case of an open flame, which has been reported in the news before, and Gree Mei has appeared, so when installing, we must avoid open flames, we must vacuum it, as long as it is installed according to the requirements, in fact, the probability of this kind of event is still very low, of course, there is no ** event in the use process after installation, this as a user does not have to worry.

    The refrigerant used in air conditioning is generally R22, called Freon 22 or simply fluorine or fluorine 22, because this refrigerant has been found to have an impact on the ozone layer, and those unscrupulous countries that have benefited from using this refrigerant for decades have proposed to control the use of this refrigerant.

    Compared with the newly developed refrigerant of R22, which has no or little impact on the ozone layer, in fact, the main component is fluorine, but in order to distinguish it from the previous R22, it is called a new refrigerant.

    Compared with R22, the relevant parameters of the new refrigerant are not as good as R22, and the only advantage is that it has little impact on the ozone layer.

    It is not the fluorine in the refrigerant that has a damaging effect on the ozone layer, but other substances in the refrigerant, and the new refrigerant is to remove or reduce those harmful substances.

    The best known refrigerant is ammonia, but ammonia is toxic, followed by R12, 22, etc. The new refrigerant has not yet surpassed R22 and R12 in characteristics.

    Refrigerant is a medium used in refrigeration and refrigeration systems. It achieves temperature control by absorbing heat in the external environment and compressing and expanding it in the system. The refrigerant is usually a liquid that can be recycled throughout the system to produce different temperature effects in different parts.

    Some commonly used refrigerants include Freon and R-410A, which are widely used in household and commercial air conditioning systems. However, due to their impact on the environment and issues such as global warming, many countries have begun to switch to more environmentally friendly alternatives, such as R-32 and R-290.
