The more and more detailed models of various refrigerants, the better, just for learning

Air conditioners are frequently used in summer, and the refrigeration effect of air conditioners will directly affect people's normal life. In summer, the indoor and outdoor temperatures are relatively high, and people will be grumpy and absent-minded in a relatively high temperature environment. So, people install air conditioners in their homes in the summer, but some air conditioners have many problems after using them for a while, such as the air conditioner won't cool down.

This situation is because the refrigerant of the air conditioner is not effective. Let me tell you which refrigerant is good for air conditioning.

1. Which kind of air conditioning refrigerant is better?1. There are many models of air conditioning refrigerants on the market. Faced with so many patterns, many people don't know how to choose. When choosing an air conditioner refrigerant, the first thing to look at is the style of the air conditioner.

Different styles of air conditioners have different models of air conditioner refrigerants.

2.The air conditioning refrigerants commonly used in household air conditioners are R410A and R22. Among them, R22 refrigerant is more suitable for constant speed air conditioning, and R22 refrigerant, also known as fluorine refrigerant, has a certain damaging effect on the ozone layer, so it is only an excess of air conditioning refrigerant**.

Refrigerant is suitable for inverter air conditioning, now inverter air conditioning is slowly replacing fixed frequency air conditioning, R410A refrigerant has a better cooling effect than R22 refrigerant, so it is loved by consumers.

2. What to pay attention to when using air conditioners1. When choosing an air conditioner, it is best to choose an inverter air conditioner. The refrigerant used in inverter air conditioners is environmentally harmless, does not destroy the ozone layer, and is also a state-supported product. It is also one of the best on the sales list.

2.When using the air conditioner, the filter in the air conditioner should be cleaned for a period of time, so as not to affect the usual use effect, not only to better choose the refrigerant, but also the filter screen is closed and cannot be blown out in the cold blades.

I have introduced some good air conditioning refrigerants, all of which are very useful air conditioning refrigerants. These refrigerants can also be selected when choosing refrigerants. Through the above introduction, do you have a new understanding of these air conditioning refrigerants?

Each refrigerant has a different style of air conditioning. Therefore, when choosing an air conditioner refrigerant, it is important to pay attention to choosing the right model. I also introduced some precautions when using air conditioners, which are common problems in daily life.

Nowadays, basically every home is equipped with air conditioning, so the question is, what are the commonly used refrigerants for household air conditioners?

R22 refrigerant.

R22 is one of the most widely used freon refrigerants, mainly used in household air conditioners and low-temperature refrigerators. The thermodynamic properties of R22 are similar to those of ammonia. The standard gasification temperature is that the condensation pressure usually does not exceed non-flammable and non-explosive, and it is safer and more reliable than ammonia in use.

The unit volume of R22 is about 60% higher than that of R12, and its refrigeration capacity and saturation pressure per unit volume are higher than those of R12 and ammonia at low temperatures. In recent years, R134A has been used as the refrigerant for large-scale air-conditioning chillers.

Main uses: R22 refrigerant, as the most widely used medium and low temperature refrigerant today, is mainly used in household air conditioning, commercial air conditioning, air conditioning, mobile air conditioning, heat pump water heater, dehumidifier, refrigeration dryer, cold storage, food freezing equipment, marine refrigeration equipment, industrial refrigeration, commercial refrigeration, refrigeration condensing units, supermarket display cabinets and other refrigeration equipment.

R-407C refrigerant.

Physicochemical properties: At room temperature and pressure, R407C is a chlorine-free fluoroalkane azeotropic mixed refrigerant, colorless gas, which is compressed liquefied gas stored in cylinders. Its ODP is 0, so R407C is an environmentally friendly refrigerant that does not destroy the ozone layer of the atmosphere.

Main use: R407C is mainly used to replace R22, which has the characteristics of clean, low toxicity, non-combustibility, and good refrigeration effect, and is widely used in household air conditioners and small and medium-sized air conditioners.

R410A refrigerant.

Physicochemical properties: At room temperature and pressure, R410A is a chlorine-free fluoroalkane azeotropic mixed refrigerant, colorless gas, and is a compressed liquefied gas stored in a cylinder. Its ODP is 0, so R410A is an environmentally friendly refrigerant that does not destroy the ozone layer in the atmosphere.

Main uses: R410A is mainly used to replace R22 and R502, with the characteristics of clean, low toxicity, non-combustible, good refrigeration effect, etc., and is widely used in household air conditioners, small commercial air conditioners, household air conditioners, etc.

R134A (tetrafluoroethane) refrigerant.

R134A is currently internationally recognized as one of the main refrigeration fluids to replace R12, commonly used in automotive air conditioning, commercial and industrial refrigeration systems, as well as as a blowing agent in the production of hard plastic insulation, and can also be used to formulate other refrigerant blends, such as R404A and R407C.

Main uses: Mainly replace R12 as a refrigerant, and is widely used in automotive air conditioning and refrigerator refrigeration.

CRR intercooled warm reminder: now there are many counterfeiting methods that are difficult to prevent, everyone should not be greedy for small bargains, must buy well-known big brands, in order to avoid potential inferior refrigerants and compressors contact and damage to the compressor.

Summary. Dear, I've kept you waiting, I'm glad to have your question. There are 5 types of refrigerants.

Refrigerants can be broadly classified into the following types based on their chemical composition and properties: ammonia, freons, alkyl compounds, carbon dioxide, and heat pump refrigerants. Each refrigerant has different characteristics and scope of application, and it is necessary to choose the right refrigerant according to the specific situation.

At the same time, it is also necessary to pay attention to the safety and environmental protection of refrigerants.

Dear, I've kept you waiting, I'm glad to have your question. There are 5 types of refrigerants. According to the different chemical composition and properties, the refrigerant can be roughly divided into the following types:

Ammonia, freons, alkyl compounds, carbon dioxide, and heat pump refrigerants. Each refrigerant has different characteristics and scope of application, and it is necessary to choose the appropriate refrigerant according to the finished situation. At the same time, it is also necessary to pay attention to the safety and environmental protection of refrigerants.

Refrigerant refers to the substance used to absorb, transmit and release heat in the refrigeration cycle, which can be divided into the following types according to its chemical composition and physical properties:1Ammonia (NH3):

It is a colorless gas with high refrigeration capacity and thermal conductivity, and is often used in large-scale industrial refrigeration equipment. 2.Freon (Freon):

It is a class of HCFC compound hidden substances, which are often used in household air conditioners, commercial cold storage and other refrigeration equipment. However, due to its destruction of the ozone layer and pollution to the environment, it has been gradually phased out. 3.

Alkyl compounds: such as propane, butane, etc., are a class of natural gas, with low cooling capacity and thermal conductivity, and are often used in small refrigeration equipment such as household refrigerators and car refrigerators. 4.

Carbon dioxide (CO2): It is an environmentally friendly refrigerant with high refrigeration capacity and thermal conductivity, but the use pressure is high, and it is generally used in large-scale refrigeration equipment such as supermarket cold storage and commercial freezers. 5.

Heat pump refrigerant: such as R410A, R407C, etc., is a class of environmentally friendly refrigerants, commonly used in heat pump air conditioning, ground source heat search pump and other household and commercial refrigeration equipment. It should be noted that the type and selection of refrigerants should be determined according to the specific refrigeration equipment and use environment, and different refrigerants have different characteristics and scope of application.

At the same time, in the process of use, it is also necessary to pay attention to its safety and environmental protection, so as to avoid causing unhealthy effects on the human body and the environment.

Which is the best air conditioning refrigerant - what are the models of air conditioning refrigerant.

The models of air conditioning refrigerants are R22, R410A, R32, R290, etc. Among them, Biyuan R22 is the most commonly used refrigerant in Yeshuru, which has a good refrigeration effect, but its content of harmful substances is high, and it has been banned from use by the international ban; R410A is a second-generation refrigerant, which has a better cooling effect than R22 and a lower content of harmful substances, making it the preferred refrigerant to replace R22. R32 and R290 are third-generation refrigerants, which have better cooling effect and lower content of harmful substances, and are suitable for air conditioning systems with high environmental requirements.

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.

Automotive Refrigerant:

The refrigerant in the automobile air conditioning system, commonly known as refrigerant, is used to transfer heat due to its rapid heat absorption and heat release characteristics during refrigeration work, so as to achieve the effect of rapid refrigeration.

The English name of the refrigerant is Refrigerant, so the first letter R is often used to represent the refrigerant, followed by the name of the refrigerant, such as R12, R22, R134A, etc.

R11 high is mainly used in large-scale ** air conditioning (centrifugal chillers) and other refrigeration equipment R123 high replaces R11, is used for large-scale ** air conditioning (centrifugal chillers) and other refrigeration equipment R12 medium and low is mainly used in automotive air conditioners, household refrigerators, small refrigeration and freezing.

The types of air conditioning refrigerants are: R22 refrigerant, R-134A refrigerant, R290 refrigerant, R410A refrigerant, etc.

Difference 1, the degree of environmental protection is different.

R22 is a single refrigerant, its scientific name is "difluorochloromethane", and the boiling point is -41°C. It is colorless and odorless, but it is a member of the Freon family. Exhaust gases emitted into the air can damage the ozone layer and cause environmental problems.

R-134A refrigerant is relatively environmentally friendly and is now a more commonly used refrigerant.

Difference 2: The area and environment of use are different.

R-134A (tetrafluoroethane) boiling point, relatively low. Used in heat pumps, once the ambient temperature decreases, the thermal efficiency of the heat pump decreases. As a result, this refrigerant is not as widely used as R22 and is generally used indoors or in tropical areas.

Difference 3, the degree of security is not the same.

R290 is a new environmentally friendly refrigerant, but when mixed with air, it is prone to safety accidents such as **, and other refrigerants are relatively safe and will not occur**.
