Is it necessary to vacuumize when installing the variable frequency air conditioner? Does not vacuum

Four seas network: with the arrival of hot weather, and ushered in a large number of buying air conditioning upsurge. More and more people choose to buy variable-frequency air conditioning, the power saving advantages of variable-frequency air conditioning are loved by everyone. However, during the installation of variable frequency air conditioner, many people see that workers need to vacuumize before installation. Is it necessary to do so? What will happen if they do not vacuumize?

Do you need to vacuumize when installing the variable frequency air conditioner

Of course, it is also written on the air conditioner to vacuumize it. It is not allowed to use the refrigerant drain pipe of the external machine. It is necessary to use the vacuum pump. Since the instructions are written in this way to ensure the use of the air conditioner, we'd better be accurate.

What happens if the inverter air conditioner doesn't vacuum

1. The variable frequency air conditioner uses environmental protection refrigerant for refrigeration. The model is generally r401a. The disadvantage of this refrigerant is that it is afraid of moisture. Once encountering moisture, not only the cooling and heating effect will be reduced, but also the refrigeration oil of the compressor will be fatally hit. The air conditioner manual is also very clear.

2. If the air conditioner is installed without vacuumizing, the internal air evacuation mode of the common air conditioner is adopted, which will change the proportion of refrigerant components, affect the refrigeration and heating performance of the air conditioner, and consume more power. Once the vacuum pumping is not standardized, there will be air in the air conditioning system, which will oxidize and corrode the whole air conditioning system, and may cause air conditioning failure.

3. If there is no vacuum during installation, once the refrigerant in the machine pipe contacts with the air, it will form ice after a long time, which will cause the air conditioner to fail to work.

4. Without vacuumizing, the water and air mixed into the refrigerant system will lead to deterioration of the compressor oil, resulting in poor operation efficiency of the compressor, increased current consumption, increased pressure and noise of the compressor. In general, there will be obvious problems in a year.

5. If it is installed without vacuumizing, the service life of the air conditioner will be seriously affected, and the effect of cooling and heating will be worse, which means that it costs money to buy an unqualified air conditioner.

Why some variable frequency air conditioners do not vacuum

1. Some domestic brands do not vacuumize because the installers are not professional and do not have special vacuumizing equipment and technology. Installation workers lack of installation technology, etc.

2. The quality of the installers is poor. In order to be lazy, the installers take the installation quality of the user's air conditioner as a joke.

How to deal with the frequency conversion air conditioner without vacuumizing

If there is no vacuum pumping when installing the air conditioner, there is generally no way to remedy it, only a complete set of replacement. If the user finds that the air conditioner has this problem, do not have any illusions, immediately complain to the manufacturer and the seller, and instruct them to replace the air conditioner immediately. Don't let yourself suffer.
