6.2. longfresh compartment
6.2.1.Sensors
The longfresh compartment is also equipped with two NTC resistors, the longfresh evaporator
sensor and the longfresh air sensor. The longfresh air sensor measures again the actual
temperature, the longfresh evaporator temperature the evaporator temperature. The air
sensor is again responsible for controlling the compressor and fan, the evaporator sensor for
ending the defrost process and for fault diagnosis.
6.2.2.longfresh-fan
The longfresh compartment is equipped with a 230V shaded-pole motor with radial fan. During
normal operation, the longfresh-fan runs parallel to the comp10 min overrun. The
circulating air creates a layer of air around the longfresh shelves to ensure even temperature
distribution on the outside of the longfresh compartment. Without fan, very low parallel
temperatures would result which would lead to condensation or ice build-up.
In certain modes of operation such as
-
warm refrigeration temperatures (see point 5.2.4) or
-
fast cooling,
the longfresh fan within the refrigerator runs in cycling mode (1 min ON; 2 min OFF). The
cooling performance within the longfresh compartment is therefore reduced and compressor
run-time prolonged.
