What refrigerant information? Thanks, what is refrigerant?

The commonly used air conditioning refrigerants are mainly as follows:

R22 (Freon): is a commonly used refrigerant, but has now been banned in many countries due to its destructive effect on the ozone layer.

R410A: is a relatively new refrigerant, which is widely used in modern air conditioning systems. It has a high cooling efficiency and a relatively low environmental impact.

R134A: Similar to R410A, it is a newer refrigerant that is also widely used in modern air conditioning systems.

R407C: It is a mixed refrigerant, which is mixed by a certain proportion of R32, R125 and R134A, which has good refrigeration performance and environmental friendliness.

In addition, there are some other refrigerants, such as R290 (propane), R32, etc., but they are not available for all types of air conditioning systems and need to be selected according to the specific air conditioning type and requirements.

As a representative of the new generation of environmentally friendly refrigeration media, Chemours refrigerants are more environmentally friendly than refrigerants composed of chemicals such as freon, such as higher safety, lower global warming potential, and lower ozone depletion potential. At the same time, Chemours refrigerants also have higher cooling efficiency and stability, which can be widely used in commercial air conditioners, home air conditioners, automotive air conditioners, and other industries. The technological advantages of Chemours refrigerants, combined with increasingly stringent environmental regulations, have made them a popular choice in the refrigerant market.

The growing popularity of Chemours refrigerants is the result of Elax New Energy's tireless efforts in the market. However, as an environmentally friendly refrigeration medium, Chemours refrigerants still present some challenges. For example, Chemours refrigerants are more expensive and require more capital investment; At the same time, the promotion of new refrigerants requires people to accept new usage habits.

These problems need to be solved by the joint efforts of refrigerant companies and businessmen to lay a solid foundation for the sustainable development of the industry.

As mentioned above, the gradual popularization and widespread application of Chemours refrigerants not only meets people's needs for environmental protection, health and efficiency, but also makes great contributions to the cause of environmental protection, and also brings feasible development solutions for the refrigeration industry. With the promotion and support of Elas, we believe that the market share of Chemours refrigerants will continue to increase, and make a greater contribution to protecting the environment and saving energy.

Refrigerants are R12, R22, R134A, R152A, R600A, H-01, Rh, H, R404, R401, R152A and R22 mixtures.

Commonly used refrigerants are R12, R22, R134A, R152A, R600A. Generally, R12 and R22 can be replaced. R152A, H-01, RH, H, R404, R152A and R22 are mixed refrigerants and can be replaced with R12.

The application of non-azeotropic mixed working fluid single-stage compression can obtain very low evaporation temperatures, and can increase the cooling capacity and reduce power consumption. Its properties are directly related to the refrigeration effect, economy, safety and operation management of the refrigeration unit, so the understanding of the refrigerant property requirements cannot be ignored.

How it works:

The working fluid that completes the thermodynamic cycle in the chiller. It sucks the heat of the cooled object at a low temperature and then transfers it to the cooling water or air at a higher temperature. In vapor compression refrigerators, a working fluid that can be liquefied at room or low temperatures is used as a refrigerant, such as freon (fluorine, chlorine, bromine derivatives of saturated hydrocarbons).

Azeotropic mixed working fluid (azeotropic solution mixed with two kinds of freons in a certain proportion), hydrocarbon compound rubbers (propane, ethylene, etc.), ammonia, etc.; In gas compression chillers, gaseous refrigerants such as air, hydrogen, helium, etc., are used, which are always gaseous in the refrigeration cycle; In absorption refrigerators, a binary solution consisting of an absorbent and a refrigerant is used as the working fluid.

Refrigerants, of which there are many kinds, are generally compressed into liquids and packed in jars, but at room temperature they are gases.

In the past, freon was generally used. But now it is banned in the world because it will destroy the ozone layer. There are also on the market today. They are sold at shops that repair air conditioners, refrigerators, and other home appliances.

Refrigerant definitionRefrigerant, also known as refrigeration working fluid, refrigerant, refrigerant, refrigerant, is a working substance that is constantly circulating in the refrigeration system and changes through its own state to achieve refrigeration.

The refrigerant absorbs the heat of the cooling medium (water or air, etc.) in the evaporator and vaporizes, and in the condenser it transfers the heat to the surrounding air or water and condenses.

Commonly used refrigerantsThere are: ammonia, freon-12, freon-22, R-134A, R-404A refrigerant, R-410A refrigerant, azeotropic refrigerant and hydrocarbon refrigerant.

Refrigerant, also known as refrigerant, refrigerant, refrigerant, is a medium substance used to complete energy conversion in various heat engines. These substances typically increase their power by a reversible phase transition, such as a gas-liquid phase change. Such as steam in a steam engine, refrigerant in a refrigerator, and so on.

When the general steam engine is working, the heat energy of the steam is released and converted into mechanical energy to generate the driving force; The refrigerant of the refrigerator is used to transfer heat from low temperatures to high temperatures.

For example, the air conditioner in the car uses refrigerant, and some halogenated hydrocarbons (especially chlorofluorocarbons) are the most common working medium in traditional industry and life, but now they are gradually eliminated because they cause a hole in the ozone layer. Other widely used working media are ammonia, sulphur dioxide and non-halogenated hydrocarbons (e.g. methane).

Also called refrigerant. Generally, it is a low-boiling liquid, which absorbs the surrounding heat when it evaporates, causing a low temperature, and then compresses it and liquefies. Recyclable. Commonly used are ammonia, freon (an organic compound containing fluorine and chlorine), etc.

In the refrigeration unit, there must be a working fluid in which the state changes and completes the thermodynamic cycle process, so that the refrigeration device can continuously and stably supply cooling to the outside world, and the circulating working fluid is called refrigerant. At present, there are dozens of substances that can be used for refrigeration, but there are only a dozen kinds of refrigerants used in the ordinary refrigeration range (5 120C), and only a few refrigerants are used in air conditioning and refrigeration systems.

Core tip: Refrigerant is a working fluid used to transfer heat energy and produce freezing effect in the refrigeration and air-conditioning system. According to the working mode, it can be divided into primary refrigerant and secondary refrigerant.

According to the classification of material properties, it can be divided into natural (natural) refrigerant and synthetic (synthetic) refrigerant. In an air-conditioning system, heat is transferred through evaporation and condensation. Commonly known as Freon (Freon).

Refrigerant: (—The following is the refrigerant and refrigerant are collectively referred to as refrigerant) Ideal refrigerant: non-toxic, non-**, non-corrosive effect on metals and non-metals, non-combustion, easy to detect leakage, chemically stable, non-destructive to lubricating oil, with high latent heat of evaporation, harmless to the environment.

Generally, refrigerants and refrigerants are collectively referred to as refrigerants, which are used to transfer heat energy and produce freezing effects in refrigeration and air-conditioning systems. Cold coal is a substance that easily absorbs heat into gas, and easily exothermic into liquid. In the early refrigeration plant, ammonia was used as cold coal, and when ammonia was pressurized, it was exothermic and turned into liquid; When a high-pressure liquid is depressurized and turns into a gas, it absorbs heat.

The cold coal used in the air conditioner commonly used in daily life is chlorofluorocarbon, but the fluorochlorocarbons used in the past will destroy the ozone layer, and scientists have developed chlorofluorocarbons that will not destroy the ozone layer: Relevant information disclaimer: This article only represents the author's personal views, please readers for reference only, and please verify the relevant content by yourself.

The refrigerant is the working fluid in the refrigerator, which circulates in the refrigerator system, and continuously exchanges energy with the outside world through the cyclic change of its own thermal state to achieve the purpose of refrigeration. It is customary to call refrigerant as refrigeration working medium or working fluid for short.

In a liquid evaporative refrigerator, the refrigerant evaporates at the required low temperature and draws heat from the cooled object; It then condenses at a higher temperature and emits heat to the outside world. Therefore, only substances that are capable of vaporizing and condensing in the operating temperature range are possible to be used as refrigerants. Most refrigerants are gaseous at room temperature and pressure.

Selection criteria for refrigeration agents:

1. Refrigeration performance We expect the condensation pressure of the refrigerant to be not too high, the evaporation pressure is above the atmospheric pressure or not too much lower than the atmospheric pressure, the pressure is moderate, the exhaust temperature is not too high, the refrigeration capacity per unit volume is large, and the coefficient of performance of the cycle is high. Good heat transfer. 2. Practicability The chemical and thermal stability of the refrigerant is good, and it does not decompose and deteriorate during the refrigeration cycle.

Innocuous. Wide, cheap. 3. Environmental acceptability should meet the environmental protection requirements of protecting the atmospheric ozone layer and reducing greenhouse benefits, the ozone depletion index of the refrigerant must be 0, and the greenhouse benefit index should be as small as possible.

At present, the refrigerant is determined according to the type and specification of the compressor

Air conditioning compressor: generally R22 (fixed frequency) and R410A (inverter).

Refrigerator compressor: generally R600A and R134A

The choice of refrigerant depends on the compressor you are using. What refrigerant is applied to the compressor, you can charge whatever refrigerant you want.

Refrigeration is a gerund, and generally something is not cooled, but refrigerant is just a noun, like freon, which is a refrigerant.

Refrigeration and refrigeration, as a science and technology, refers to the use of artificial methods to cool an object or object in a certain time and space, so that its temperature is below the ambient temperature.

Refrigerant Refrigerant is the working medium in the refrigerator, which circulates in the refrigeration system and exchanges energy with the outside world through the change of its own thermal state, so as to achieve the purpose of refrigeration.
