Is there any problem with the lengthened connecting pipe of the split air conditioner?

The length of the piping of the air conditioner is specified, and increasing the length of the piping strictly requires the addition of freon, one is to ensure the refrigeration effect. Second, it can ensure the life of the compressor. In the process of working of the air conditioner, the freon is pressed to the internal machine with the compressor, and then the energy is released in the U-shaped pipe of the internal machine and returned to the compressor.

Fluorine is lubricated by refrigeration oil during the flow process. Therefore, the manufacturer of the first air conditioner has given the length of the piping according to the power of the air conditioner compressor in the factory, and it is generally recommended not to lengthen the piping. But short distances like yours are allowed, but it's best to add extra fluoride.

The performance of different brands of split air conditioners is not the same, and the copper pipe of the same air conditioner is definitely not as easy to use as the copper pipe is not lengthened, because the pipe of the copper pipe will lose energy, of course, it is no problem if it is not very long. Haier's words generally cannot exceed 15 meters long, and the cooling effect and life are generally not affected within 5 meters, and the air conditioning copper pipe generally does not need to be refrigerated within 7 meters, so don't worry too much. Hehe.

In the past, the manufacturer's air-conditioning connecting pipe was 5 meters, but now the manufacturer has changed the connecting pipe to 3 4 meters in order to reduce costs.

In the past, the total length of the lengthened pipe of the air conditioner did not exceed 7 meters, and freon should be added if it exceeded 7 meters. Nowadays, some air conditioners do not add freon to the connecting pipe below 30 meters. (The lack of freon affects the heat dissipation of the air conditioner compressor and affects the life of the air conditioner).

If you look at the manual, you will know whether you want to add freon.

Generally speaking, of course, it is better not to lengthen it. But you don't have to worry, the impact of lengthening 1m will not be great, and the manufacturer has taken this aspect into account when designing. If the air duct is optimized or a new type of refrigerant is used in a large-horsepower air conditioner, the amount of refrigerant injected may be reduced.

Pay attention to whether there is any loss of refrigerant during installation. (For example, there is air in the refrigerant exhaust machine) if there is one.

No. Generally speaking, the length should not exceed 5mYou don't need to add it. As for the amount of storage at the factory, it is related to his design, and users should not care too much. Theoretically, a short connecting tube would work a little better. But the difference of 1-2m will not feel coming.

It will be lost a lot in the process of cold air transmission, which is why copper pipes can not be used alloy pipes.
