What is a refrigerant tube and what is the function of a refrigerant tube?

Air conditioning system. medium, refrigerant.

The flow passes through the pipes that connect the main refrigeration components such as heat exchangers, valves, compressors, etc.

Air conditioner refrigerant. Pipe refers to the pipeline that connects the main refrigeration components such as heat exchangers, valves, and compressors through which the refrigerant flows in the air conditioning system. Copper pipes are usually used.

The air conditioning system transports cold or heat to the end, and divides it from the medium conveyed, there are several ways, one is to directly supply air, one is to transport hot and cold water, and one is to directly take the refrigerant. For systems with direct air supply and hot and cold water delivery, the refrigerant lines are generally concentrated in the vicinity of the main engine. For systems that run directly through the refrigerant, such as VRV systems, the refrigerant duct will go directly into the air-conditioned space and connect the outdoor main unit to the indoor unit.

The refrigerant line is long. The refrigerant pipeline is too long, and the expansion valve generally adopts the external equilibrium view mode to cope with the evaporator.

Pressure drop from the inlet to the suction port of the compressor. The refrigerant pipeline is a pressure-bearing component, and its burst pressure should meet more than 5 times of the operating pressure, or more than 3 times the maximum possible pressure.

R410A refrigerant pipes generally use phosphoric acid deoxidation seamless steel pipes.

For this new refrigerant VRV system, the refrigerant piping must be degreased copper tubing with a certificate of degreasing from the manufacturer.

Air conditioners are divided into single cooling air conditioners and cold and warm air conditioners, the working principle is the same, and the refrigerant generally used in air conditioners is freon.

The characteristic of Freon is that when it changes from a gaseous state to a liquid state, a large amount of heat is released. When the liquid state changes from a gaseous state, it absorbs a large amount of heat. Air conditioners are designed based on this principle.

The compressor compresses the gaseous refrigerant into a gaseous refrigerant at high temperature and pressure, and then sends it to the condenser.

The outdoor unit becomes a liquid refrigerant at room temperature and high pressure after heat dissipation, so the outdoor unit blows hot air.

Then to the capillary, into the evaporator (indoor unit), because the refrigerant from the capillary to the evaporator after the space suddenly increases, the pressure decreases, the liquid refrigerant will vaporize, become a gaseous low-temperature refrigerant, thereby absorbing a lot of heat, the evaporator will become cold, the fan of the indoor unit will blow the indoor air from the evaporator, so the indoor unit blows out of the cold air.

When the water vapor in the air meets the cold evaporator, it will condense into water droplets and flow out down the water pipe, which is why the air conditioner will produce water.

The refrigerant tube mainly refers to the connecting pipe between the internal machine and the external machine, which is used to walk the refrigerant, so it is called the refrigerant pipe and also called the connecting pipe. The common air-conditioning refrigerant pipe refers to the pipeline connecting the main refrigeration components such as heat exchanger, valve, compressor and so on through which the refrigerant flows in the air-conditioning system. The refrigerant pipe of the air conditioner is usually made of copper.

First of all, refrigeration needs a medium, and there are several types of media, including some new mixed refrigerants such as water, freon, ammonia, etc.

The pipes used to transmit the medium are usually steel pipes or cast iron pipes used in water coolers, also known as cold water pipes.

However, the medium is Frion and other chemical refrigerants are transmitted by copper pipes, such as many air-cooled units and modular units.

The copper pipe connecting the air-cooled unit and the terminal equipment is called the refrigerant tube.

Hello, I am glad to answer for you what is the air conditioning refrigerant tube, which refers to a pipe connected to the internal and external units, which is used to walk the refrigerant, so it is also called a connecting pipe. When the air conditioner is in use, the internal refrigerant needs to pass through this tube and flow through the main components such as heat exchanger and compressor, so this refrigerant tube is very important. The refrigerant pipe is usually made of copper pipe, the pipeline is long, the pipeline belongs to the bearing pressure parts, and the bursting pressure is very strong, so when in use, the refrigerant pipe is not easy to be damaged and has a long service life.

RefrigerantThe tube refers to a tube that connects the inner machine and the outer machine, which is used to take the refrigerant, so it is also called the bridge connection.

Air conditioning refrigerant pipe refers to the air conditioning system.

medium, refrigerant skin combustible agent.

The pipes that flow through which the main refrigeration components such as heat exchangers, valves, compressors, etc. are connected. Copper pipes are usually used. The air conditioning system transports cold or heat to the end, and there are several ways to divide it from the conveyed medium, one is to directly supply air, one is to transport cold water or hot water, and the other is to directly take the refrigerant.

Problem description: air conditioning system"What is refrigerant piping?"Dongdong?

Analysis: In the refrigeration and air conditioning system, it is used to transfer heat energy and produce a working fluid for the freezing effect. 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.

Ideal refrigerant: non-toxic, non-corrosive, non-corrosive to metals and non-metals, non-combustion, easy to detect leakage, chemically stable, non-destructive to lubricating oil, with relatively latent heat of evaporation, harmless to the environment.

Ideal physical properties of refrigerants.

1.The pressure of evaporating potatoes should be high.

The evaporation temperature will vary with the application temperature, for example, the evaporation temperature of the chiller is about 0 5, the evaporation temperature of the freezer is about -20 30, and the evaporation temperature of the household air conditioner is about 5 10. If the evaporation pressure of the refrigerant is lower than the atmospheric pressure, the air is easy to enter the system, and the system is more difficult to treat, so it is hoped that the evaporation pressure of the refrigerant can be higher than the atmospheric pressure when the refrigerant evaporates at low temperature.

2.The latent heat of evaporation should be large.

The latent heat of evaporation of refrigerant is large, which means that a large amount of heat can be absorbed by using less refrigerant.

3.The critical temperature should be high.

If the critical temperature is high, it means that the condensation temperature of the refrigerant is high, and the air or water at room temperature can be used to cool the refrigerant to achieve the effect of condensation and liquefaction.

4.The condensing pressure should be low.

The low condensation pressure means that the refrigerant can be liquefied at a lower pressure, and the compression ratio of the compressor is small, which can save the horsepower of the compressor.

5.The solidification temperature should be low.

The freezing point of the refrigerant should be low, otherwise the refrigerant will freeze in the evaporator and cannot be circulated.

6.The specific volume of gaseous refrigerant is smaller.

The smaller the specific volume of the gaseous refrigerant, the better, the volume of the compressor can be reduced to reduce the cost, and the suction pipe and exhaust pipe can be piped with a smaller refrigerant.

7.The density of liquid refrigerant should be high.

The higher the density of the liquid refrigerant, the smaller the piping can be used.

8.If the soluble clumps are in the refrigerated oil, the system does not need to be equipped with an oil separator.

Ideal refrigerant chemistry.

1.Chemically stable.

The evaporation temperature will change with the application temperature, for example, the evaporation temperature of the water chiller is about 0 5, and the refrigerant only has physical changes, but no chemical changes, and has no decomposition effect.

2.Non-corrosive.

It is non-corrosive to steel and metal, and ammonia is corrosive to copper, so copper pipe piping should not be used in ammonia refrigeration system; The insulation should be good, otherwise the insulation of the compressor motor will be damaged, so ammonia should not be used in closed compressors, so as not to be in direct contact with the copper coil.

3.No environmental pollution.

It is harmless to the natural environment, does not destroy the ozone layer, and has a low greenhouse effect.

4.Non-toxic.

5.It does not have the ability to be ** and flammable.

Is it useful to keep the low-pressure pipe of the air conditioner insulated?

Useful. This method can make the air conditioner better refrigerated, and the poor can extend the life of the low-pressure pipes, so that the air conditioner can be used better.

How to add refrigerant to the air conditioner to cool the Shouling oil.

After the air conditioning system pipeline is filled with refrigerant, it cannot be filled with refrigerant oil. If the refrigerant oil is forcibly filled during this celebration, it will cause the refrigerant to leak or more air to enter the refrigeration system lines. Before filling the refrigerant in the refrigeration system pipeline, vacuum the refrigerant with a vacuum pump and fill the refrigerant oil through the injection port (such as a needle valve) on the pipeline.

Vacuuming, filling with refrigerant oil and adding refrigerant.

What insulation materials should be used for air conditioning system piping and refrigeration equipment?

**The refrigerant used in air conditioners is R22, which is the most commonly used refrigerant in China. New environmentally friendly refrigerant R410A, all things refrigerant, R407C, etc. The characteristics of various refrigerants are as follows:

Refrigerants that are widely used in compression-type refrigerants are ammonia, freon, and hydrocarbons. Refrigerants can be divided into five categories according to their chemical composition: inorganic composite refrigerants, freons, saturated hydrocarbon refrigerants, unsaturated hydrocarbon refrigerants, and azeotropic refrigerants.

Refrigerants can be divided into three categories based on the condensing pressure: high-temperature (low-pressure) refrigerants, medium-temperature (medium-pressure) refrigerants, and low-temperature (high-pressure) refrigerants.

What is Air Conditioner Refrigerant Ducting? Answer: It mainly refers to the connecting pipe of the internal machine and the external machine, which is used to walk the refrigerant, so it is called the refrigerant pipe, also called the connecting pipe.

What is the difference between a refrigerant line and an air conditioner condensate line? A: The main difference is that the condensate tube is condensate, and its material is plastic, and the material of the refrigerant tube is copper.
