As will be appreciated, refrigerant piping is generally used in devices that perform cooling / heating or cooling using a refrigerant cycle such as an air conditioner or a refrigerator.

The refrigerant cycle generally consists of a series of cycles of compression-condensation-expansion-evaporation. Here, the refrigerant cycle is condensed and evaporated by a heat exchanger.

The heat exchanger includes a refrigerant pipe through which the refrigerant flows, and a blowing fan blowing outside air through the refrigerant pipe.

With this structure, the outside air passing through the outer surface of the refrigerant pipe by the blowing fan is heat-exchanged with the refrigerant flowing in the inside of the refrigerant pipe.

On the other hand, the heating water used in the boiler contains a foreign substance because it is not particularly purified and used. The foreign matter contained in the heating water floats and floats when the heating water circulates rapidly in the pipe, but when the boiler is stopped or the pipe is formed with a lot of bends, .

The foreign substances deposited and accumulated as described above are fixed in the pipe as the heat is repeatedly applied, and this causes a problem of interfering with the flow of the circulating hot water or corroding the pipe.

Therefore, as the time passes, the diameter of the pipe through which the heating water can actually pass gradually becomes smaller, so that the flow of the heating water is not smooth and the life of the boiler is shortened.

Particularly, there is a great problem that the various piping does not minimize the resistance of the fluid flow.
