The copper pipe joint connecting the internal and external machines is not sealed, resulting in fluorine leakage. After using for a period of time, it can not be used normally. In the case of slow leakage, the air conditioner can not be cooled and heated normally after one year. In the process of installation, the connection copper pipe is broken due to improper operation, which leads to the increase of pressure in the system, resulting in the heating and abnormal shutdown of the compressor, or the burning of the compressor in serious cases. During the installation process, improper operation led to the rupture of the connecting copper pipe and Freon leakage, resulting in complete failure of refrigeration and heating.
