Occurrence read out from the recording chart
When the moisture in the cargo is excessive,
the cooling capacity becomes insufficient
during pull-down operation since frosting
occurs excessively. Since the temperature
rises before reaching the set point
temperature, defrosting is repeated at outside
of the in-range temperature.
Abnormal content and abnormal point
The operation is not abnormal. Until the
amount of the frost on the evaporator is to be
reduced, defrosting with the frost detection is
repeated. In 2 to 3 days, defrosting interval will
return to normal.
