What is the reason why the radiator of the ice maker in the tea shop freezes?

When the weather is hot, there is a high probability that the ice machine in the tea shop will break down, and everyone who has opened a tea shop knows it. If it is not solved for a long time, the life of the machine will be shortened, which will affect the operation of the store. What is the reason why the radiator of the ice maker in the tea shop freezes? The milk tea equipment is matched with the teacher Lan Xin's kitchen utensils to answer your questions, and the troubleshooting of the evaporator freezing of the water bar ice maker:

1, insufficient refrigerant. Due to long installation or use time, refrigerant leakage or leakage may occur. After the refrigerant in the refrigeration system is reduced, the evaporation pressure is too low, which causes the evaporator to freeze, and the freezing position is generally in the front of the evaporator. The elimination method is to deal with the leaking part first, and add enough refrigerant to eliminate the fault;

2. The gas pressure of the temperature sensing package of the mechanical thermostat with temperature failure changes with the temperature change, which drives the thermostat contact to act. Due to contact adhesion, insufficient spring elasticity and other reasons, the contact is normally closed, and the ice maker continues to open, resulting in icing. Replace the thermostat and troubleshoot;

3. Long-term compressor failure, compressor compression efficiency reduction, or compressor gas distribution system damage, resulting in low pressure and icing. The freezing position is also at the front of the evaporator. The former is supplemented with some refrigerant, and the fault can be eliminated. If the fault still exists, the compressor must be replaced;

4. Too much refrigerant. Some air conditioners are refilled with refrigerant due to replacement, leakage and other reasons, and maintenance personnel add more refrigerant due to improper operation, resulting in excessive refrigerant flowing to the evaporator and evaporation and freezing. This kind of ice mainly freezes around the evaporator and compressor oil return pipe. Discharge excess refrigerant, and the fault will be eliminated;

There is a lot of dust on the evaporator. After the ice maker is used for a period of time, dust in the air or microorganisms generated by the evaporator will accumulate on the evaporator, which will hinder air circulation and reduce heat exchange. If the temperature is too low, the evaporator will freeze. The freezing position is at the rear of the evaporator. After the ice melts, rinse the evaporator with water and brush along the fins with a soft brush. Be careful not to wet the electrical parts. After cleaning, the fault will be eliminated.

If you know some basic knowledge of ice machine, you can avoid many problems. Especially in the operating milk tea and drink shop, if the machine breaks down, it will not only lose one machine, so everyone should know more about the basic knowledge of ice makers and know how to maintain their own machines.
