As a refrigeration device, the main components of an industrial water chiller include a compressor, evaporator, condenser, capillary throttle valve, etc., thereby achieving the refrigeration effect of the unit. In the actual use process, it is inevitable that some faults will occur in the cooling system of the water chiller, leading to the alarm of the water chiller. What are the common factors that cause the alarm of the cooling system of the water chiller?
1. Insufficient refrigerant leads to high exhaust temperature;
2. Compressor motor fault (overcurrent protection, overheat protection, etc.), resulting in high exhaust temperature; (General situation)
3. The condensation pressure is too high, causing the exhaust temperature to be too high. (General situation);
4. The opening of the expansion valve is too small or too large, causing high exhaust temperature;
5. The evaporator frosts seriously, affecting the heat exchange effect;
6. The throttling device is dirty or blocked (expansion valve, capillary tube);
7. The suction pressure is too low; (There is air in the return pipe);
8. The suction pipeline leaks when the compressor is running;
9. The oil separation core of the compressor is blocked or there are impurities in the oil;
10. Excessive refrigerant charge;
11. Pipeline leakage causes a large amount of refrigerant to escape;
12. The environment is harsh (such as hot weather).
