What does a refrigerant do, what does a refrigerant do?

The function of the refrigerant is mainly to make the refrigeration device have safe, reliable and good economic operation performance within the specified refrigeration temperature range, and will not cause environmental pollution. 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. Zhiyun Refrigeration hopes to refer to the following.

Because refrigeration does not actually produce cold energy as everyone thinks, refrigeration is actually a transfer of energy, using refrigerants.

A process of phase change, like sprinkling water, can feel cool, water from liquid into gas to absorb heat, and boiling water vapor into liquid to release heat. Let me tell you the principle of refrigeration, the compressor compresses the refrigerant into a high-temperature and high-pressure gas, which is equivalent to water vapor, and then passes through the condenser.

It is cooled and condensed into a liquid refrigerant at high pressure, which then passes through a flow restrictor (the throttle phase reduces the pressure. ) becomes a liquid at low temperature and low pressure, and goes out of the flow controller to the evaporator.

This is when the liquid refrigerant starts to turn into a gas that absorbs heat like a sprinkler of water. So it's refrigerated. Then go back to the compressor to start the recirculation from there.

Refrigerant, also known as refrigeration working fluid, is commonly known as refrigerant in some areas of the south. It 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.

R-12 R-12 refrigerant is also known as R12, Freon 12, F-12, CFC-12, difluorodichloromethane, and the trade name is Freon 12.

Refrigerant is a gaseous substance that is easy to liquefy at room temperature, and it is used to absorb heat from liquid gasification and play a role in refrigeration. In a refrigeration system, the task of the refrigerant is to transfer heat. The ideal refrigerant should have the characteristics of low boiling point, low condensation point, non-corrosive to metal, non-flammable, non-toxic, odorless, easy to detect and low-cost.

At present, ammonia (NH3) and freon are commonly used in production. According to the temperature range of refrigerant, it can be divided into three categories: high temperature, medium temperature and low temperature.

High-temperature refrigerants are also known as low-pressure refrigerants. Its evaporation temperature is higher than 0 and the condensing pressure is lower than that, such as R21, etc., which is suitable for the air conditioning system of centrifugal compressors. Medium-temperature refrigerants are also known as medium-pressure refrigerants.

Its evaporation temperature is -50 0, and the condensation pressure is, such as R22, R502, etc. It has a wide range of applications, and is suitable for refrigeration devices such as refrigerators, small cold storage in canteens, refrigeration systems for air conditioning, and large cold storage for piston compressors. Low-temperature refrigerants are also known as high-pressure refrigerants.

Its evaporation temperature is lower than -50, and the condensation pressure is, such as R13, R14, etc., which is mainly used in low-temperature refrigeration equipment, such as cascade low-temperature refrigeration devices.

Refrigerant is a medium used in the refrigeration system, which absorbs and releases heat by circulating in the refrigeration circulation system, absorbing and discharging the heat in the air and discharging it outdoors, so as to reduce the indoor temperature and realize the role of refrigeration. Refrigerants are often used in refrigeration equipment such as household air conditioners, refrigerators, freezers, and commercial air conditioners, as well as in industrial refrigeration, medical equipment, building air conditioners, and other fields.

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 due to the unremitting efforts of leading manufacturers such as Elax in the market. However, as a new and environmentally friendly refrigeration medium, Chemours refrigerants still face some challenges. For example, Chemours refrigerants are more expensive and require more capital rebates. At the same time, the promotion of new refrigerants requires people to accept new 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.

In summary, 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 leading companies, it is believed that the market share of Chemours refrigerants will continue to increase, making greater contributions to environmental protection and energy saving.

When introducing refrigerator products, they will talk about the refrigerant of the refrigerator, so what role does the refrigerant play? Let's give you a detailed introduction: Refrigerant, also known as refrigeration working fluid, is the working fluid medium of the refrigeration cycle.

The refrigerant absorbs the heat of the cooled object in the evaporator and vaporizes it, and transfers the absorbed heat to the environmental medium in the condenser, so as to achieve the purpose of refrigeration. At present, there are more than 80 kinds of substances that can be used as refrigerants, and the most commonly used are ammonia, freons, water and a few carbons.

Refrigerants. It is in the noisy process of the internal circulation flow of the refrigeration system, through the change of its own thermal state, the energy exchange with the outside world, so as to achieve the purpose of making the cooling energy stall.

Hello: Generally, the refrigerant is refrigerated by compressors, condensers, throttling devices, and evaporators to achieve gas-liquid conversion.

The refrigerant code is:

r, which is currently the most commonly used.

r12 and. r22.

R12 is commonly used in refrigerators, R22

Usually used in air conditioners. These two refrigerants have a damaging effect on the ozone layer and will be gradually replaced by refrigerants such as R407C and R410A, but R12 and R22 are still the most widely used refrigerants.

General refrigeration principle.

The refrigeration principle of general refrigerators The function of the compressor is to compress the steam with lower pressure into steam with higher pressure, so that the volume of steam decreases and the pressure increases.

The compressor sucks in the working fluid steam with lower pressure from the evaporator, sends it to the condenser after the pressure rises, condenses into a liquid with higher pressure in the condenser, throttles through the throttle valve, becomes a liquid with lower pressure, and sends it to the evaporator, absorbs heat in the evaporator and becomes the steam with lower pressure, and then sends it to the inlet of the evaporator, so as to complete the refrigeration cycle.

R12, R22, R410A, R600A, the latter two are environmentally friendly refrigerants.

The principle of refrigeration is to reduce the ambient temperature by absorbing heat through the evaporation of the refrigerant.

Commonly used refrigerants are R12, R22, environmentally friendly refrigerants are R134A, R600A, R406A, HFC152A, R410A, the refrigeration principle is that the steam coming out of the evaporator is pressurized by the compressor, flows into the condenser, condenses into liquid, and the liquid flowing out of the condenser flows into the evaporator after being depressurized and cooled by the capillary, and then flows into the evaporator, and the evaporative heat absorption produces the refrigeration effect, and the continuous refrigeration process is carried out in this way over and over again. The refrigeration process must have [evaporation process], [compression process], [condensation process], [throttling process], these four thermal processes.
