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 heatin
