How to add R410A refrigerant to household air conditioner

According to the above principles, after determining the position of the inner and outer machine, immediately install the internal machine hanging plate, and after the external machine and the internal machine hanging plate are installed firmly, then straighten the connecting pipe to see if the pipeline is bent and deflated; Next, check whether there are cracks in the flare at both ends, and if there are cracks, they should be re-flagged, otherwise fluorine will leak. Finally, check whether the control line is short-circuited or broken, and after confirming that the pipeline, control line, and outlet pipe are in good condition, tie them together and seal the connecting nozzle. When crossing the wall, two people should cooperate inside and outside the wall to slowly penetrate out to avoid strain; Connect the pipeline with the internal and external units, and connect the control line.

Next, remove the air from the ducts and the internal unit. Here's how;

1) Tighten the connected external machine joint (fine), and loosen the valve stem of the shut-off valve with a special wrench for about 1 turn;

2) Hear the squeak of the (coarse) joint of the external machine, and tighten the (coarse) joint with a sheet metal hand for about 30 seconds;

3) Loosen the valve stem of the valve on the (coarse) pipe;

4) Completely loosen the stem of the shut-off valve on the (thin) pipe. The space-time witherer empties out.

Finally, use detergent for leak detection, carefully observe whether there are bubbles coming out of each joint, and after verifying that the system is indeed leaking, tighten the valve safety cap, and then start the test operation.

First of all, household air conditioners generally add R22 refrigerant, but if you add R401 refrigerant, you must first empty R2 before you can add it.

1. The refrigeration effect of air conditioning deteriorates;

2. The air conditioning system works abnormally or even cannot work normally;

3. Air conditioning compressor burned, etc.

Air conditioners that use R22 as a refrigerant use No. 25 mineral oil, while air conditioners use R410A postester oil. These two refrigerant oils have completely different physical properties.

After the refrigerant and refrigerant are mixed, the refrigerant and refrigerant do not mix well, so the refrigerant cannot be returned to the compressor with enough refrigerant. As a result, the compressor runs under the condition of insufficient lubrication and insufficient oil quantity, and the compressor wears and even burns out.

Simple replacement will only lead to abnormal changes in refrigerant temperature and pressure, abnormal throttling, abnormal working status of the compressor system, and serious deterioration of the air conditioning effect.

Hello, air conditioning refrigerant R410A can be replaced with R22, but it is not recommended to replace it. For the average person, the most contact with refrigerants comes from air conditioning. The refrigerant is the working medium of the refrigeration cycle of air conditioning, and the refrigerant achieves the purpose of refrigeration by absorbing heat when vaporizing in the evaporator and reciprocating in the heat release cycle when condensing in the condenser.

However, due to the different models of air conditioners used, the two most common refrigerants used in air conditioners also have some differences, namely R22 refrigerant and R410A refrigerant.

1. First turn on the R410A air conditioner, and you can directly let the air conditioner run in refrigeration mode when adding fluoride in summer. When the heating state is not able to add fluoride, so when adding fluoride in winter, you can use the method of heating pulling out the reversing valve line to force the air conditioner to enter the refrigeration state and operate. 2. After the air conditioner is started normally, the fluoridation equipment can be directly connected from the process port on the low-pressure valve side of the outdoor unit.

However, in this process, the air and dirt in the fluoride tube must be removed first. Other problems and reasons: 1. Generally speaking, the oxygen addition of R410A air conditioner should be the lack of freon in the air conditioner, if the cavity is good and lacks frein oxygen, the refrigeration effect of the air conditioner will decline, so to add oxygen is to add fluoride.

2. Pressure measurement and fluoride, when observing the low pressure of R410A air conditioner in summer, when the ambient temperature is about 32 degrees, the pressure should be controlled at about 32 degrees, and when the high pressure during heating is observed in winter, it should be controlled at about after the pressure is stable. 3. Remove the fluoride equipment, remove the fluoride equipment in the refrigeration state, and tighten the seal of the external machine.

Leak. 4. After the fluoridation is completed, the R410A air conditioner with detergent foam suspected of leakage can be inspected. If not, you can contact professional maintenance personnel for on-site maintenance.

<> difference between R410 and R22 used in air conditioners: 1. R22 is difluorochloromethane.

R410A is a new large-scale environmentally friendly refrigerant.

Does not deplete the ozone layer. 2. The working pressure of R410A is about twice that of ordinary R22 air conditioner, and the refrigeration or heating efficiency is high.

r410。

R32 is a single-substance refrigerant copy, and R410A is a new type of refrigerant BAI agent, which is used to replace R22. The two are not compatible

Use. R410A new refrigerant consists of two quasi-DAOs

It is made of azeotropic mixture, mainly composed of hydrogen, fluorine and carbon elements, and 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 using new refrigerants will also be improved to a certain extent.

R410A is internationally recognized as the most suitable refrigerant to replace R22, and has been popularized in Europe, America, Japan and other countries.

R32 is better, the thermal potential of R32 refrigerant is only one-third of R410A, which can effectively reduce the harm of air conditioning to global warming, and the cooling and heating effect of R32 refrigerant is faster than R410A.

The charging capacity of R32 can be reduced, only times that of R410A, the working pressure of R32 system is higher than that of R410A, but the maximum increase is not exceeded, which is equivalent to the pressure requirements of R410A system, and the discharge temperature of R32 system is up to maximum than that of R410A, and the existing compressor needs to be redesigned.

2) Environmental Features:

The ODP (ozone depletion potential) value is 0, but the GWP value (global warming potential) of R32 is moderate, and the proportion of CO2 emission reduction is achievable compared with R22, while R410A is only, which is significantly better than R410A in terms of CO2 emission reduction.

3) Security:

R32 and R410A are non-toxic, while R32 is flammable, but among several substitutes for R22, R32, R290, R161, and R1234YF, R32 has the highest lower combustion limit LFL (lower fire limit), the least flammable, and relatively safe.

4) Cycle Performance:

In terms of theoretical cycle performance, the cooling capacity of the R32 system is higher than that of R410A, the power consumption is increased, and the comprehensive energy saving is increased, and the experimental results also show that the refrigeration system using R32 has a slight increase in energy efficiency ratio compared with R410A.

3) Safety: R32 and R410A are non-toxic, while R32 is flammable, but among several substitutes for R22, R32, R290, R161, and R1234YF, R32 has the highest lower combustion limit of LFL (lower fire limit), the least flammable, and relatively safe.

4) Cycle performance: In terms of theoretical cycle performance, the cooling capacity of R32 system is higher than that of R410A, the power consumption increases, and the comprehensive energy saving, and the experimental results also show that the refrigeration system using R32 has a slightly higher energy efficiency ratio than R410A.

2. Inverter air conditioner refrigerant.

Refrigerant, another name for refrigerant, is also known as refrigerant. Refrigerant is a medium substance that transfers heat through evaporation and condensation in the first air conditioning system.

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.

Both R410A and R32 are environmentally friendly refrigerants that protect the atmosphere. R32 refrigerant is the latest development, which is more upgraded on the basis of R410A, and has better environmental protection effect.

Inverter air conditioner can not be installed R32. Only R410 can be installed. Air conditioner outside unit to the marked.

R404A refrigerant should not be used in household air conditioners. R404A is a refrigerant used in commercial refrigeration and refrigeration equipment and is not intended for use in domestic air conditioners. Domestic air conditioners usually use refrigerants such as R410A and Weistool R22, which have characteristics and working performance that are suitable for home use.

The use of unsuitable refrigerants can lead to problems such as reduced equipment performance, increased energy consumption, environmental changes, and equipment failures. Moreover, the use of unsuitable refrigerants can cause harm to the environment, and when released into the atmosphere, these refrigerants can cause global warming or destroy the ozone layer. Therefore, when using household air conditioners, you should choose a suitable refrigerant, and carry out regular maintenance and cleaning to ensure the normal operation and longevity of the equipment.

Summary. Hello, home air conditioner filling is not recommended is a blend of refrigerants used in commercial refrigeration and freezing applications. Although it can be used in some large industrial refrigeration systems, it should not be used in household air conditioners.

Here's why:1Household air conditioners typically use a single refrigerant, such as R22 or R410A, which has good performance and matching components such as compressors, condensers and evaporators.

Mixing different types of refrigerants can lead to system inefficiencies, reduced cooling capacity, and even equipment failure. 2.The refrigeration system of a home air conditioner is usually relatively small, and filling R404A may have an uncontrollable or overloaded effect on the pressure and temperature of the system, which can easily lead to equipment failure.

3.The pipes, valves, compressors, condensers and other components in household air conditioners are of different materials and parameters from those used in commercial refrigeration systems, and filling R404A may cause damage and air leakage to these components. Therefore, it is recommended that household air conditioners only use the refrigerant specified by the manufacturer, and professional technical support should be sought when filling and replacing the refrigerant to ensure safety and effective operation of the equipment.
