What Causes The Snowflake Ice Machine To Turn On The Temperature Protection?

What causes the snowflake ice machine to turn on the temperature protection?

Most mechanical products, especially refrigeration machines, have temperature protection, and the same is true for snowflake ice machines. Providing crushed ice to the laboratory often requires long-term refrigeration. On the one hand, temperature protection is to protect the machine, and on the other hand, it also reminds users to pay attention to the possibility of malfunctions if they continue to work!

What are the reasons for the snowflake ice machine to turn on the temperature protection?
Reason 1: Defrost water flows into the sink

The water receiving tank is at the back of the refrigerator with a fixed capacity. If the defrosting water flows in, it may cause water accumulation in the refrigerator, thereby causing temperature protection. The front of the refrigerator can be raised slightly to prevent defrosting water from entering.

Reason 2: The throttle valve is not running smoothly or too smoothly

The refrigerant flow rate is controlled by the throttle valve, and if the throttle valve does not flow smoothly into the evaporator, the amount of refrigerant will be insufficient.

If it is too high, the pressure and temperature of the evaporator will rise, which will also trigger the temperature protection.

Reason 3: There is air and refrigerated oil in the evaporator

If there is more refrigerated oil attached to the evaporator, the heat transfer coefficient will decrease; if there is more air in the heat transfer tube, the heat transfer area will be reduced and the heat transfer efficiency will be reduced.

Reason 4: The evaporator should be cleaned

If the surface of the evaporator is not clean, there is dust or frost, the heat transfer effect will be reduced.

These are the reasons that will cause the snowflake ice machine to turn on the temperature protection!
