Common Refrigerator knowledge
General Knowledge of Refrigerators (II)
The running of the compressor and circulation of refrigerant are used
to lower the temperature in the refrigerator, thus keeping food fresh
and nutritious. A little noise may break out during operation. Do not
worry, since it is normal and will not interfere with your use of the
refrigerator.
Humming noise
When the compressor is running, the noise
may be higher when it starts. The humming
noise of the highly effective refrigerator may be
somewhat higher due to the powerful working
condition of the compressor.
"Clicking" noise
This is caused by the temperature controller
when the compressor is turned on or turned off
the compressor.
Whirring noise
This is caused by the air flow when the fan
of a frost-free refrigerator or fan-equipped
refrigerator is running. Fan rotating ensures
a quick decrease and an equilibration of
temperature, and also it is vital for keeping
food fresh and nutritious.
Bubbling and gurgling noise
The inner temperature would fall down quickly
when the refrigerant is flowing through the
refrigeration tubing. Slight noise may come out
during flowing, since two forms of refrigerant
exist, gaseous and liquid.
