In the event of partial blockage, the
system's performance drops in proportion
to the size of the blockage. If completely
blocked, this prevents the circulation of
the refrigerant and consequently it stops
working.
1.2 - Antifreeze
Antifreeze is extremely harmful to
the refrigeration system, especially for
the compressor.
Firstly, because of its corrosive
characteristics and high water content.
Some of the main effects are: oxide
formation (carbon) on the valve plates,
weakening and destroying the motor
insulation and corrosion of the aluminum
evaporators.
Secondly, because it does not have the
power to neutralize the effects of the water.
Antifreeze only prevents the capillary from
being blocked by ice, because it lowers
the freezing temperature of the water.
Thirdly, because it attacks the desiccants
of the filter drier.
