How to properly and professionally maintain a chiller?

1、 Protection of chiller:
1)Check if the voltage is normal and if there is a phase loss
2)Check and record the operating current
3) Measure and record whether the high and low pressure and temperature control are normal
4)During the political party, the high pressure is 1.5MPa and the low pressure is 0.45MPa4. Check if the interlock control circuit device is loose and if the chiller is aging
5) Check if the oil level and temperature are normal
6) Check for any abnormal sounds or vibrations in the compressor
7) Testing of refrigerant system
8) Overall trial and testing
9) Regularly check whether the quality of chilled water and cooling water is normal. When the water source becomes polluted or degraded, please replace the water source in a timely manner
2： Maintenance of chiller
Basic cleaning:
The main task is to clean the panel and dust filter, which should generally be cleaned once a month. The panel can be cleaned with clean water or neutral cleaning agent, and then dried before installation (do not expose to sunlight or barbecue). Remember not to use hot water above 40 degrees Celsius, and strictly prohibit the use of gasoline, volatile oils, mixed solvents, friction powder, disinfectants, and cleaning agents to clean plastic parts such as the panel. The dust filter can filter out dust in the air. If the dust clogs the mesh, it will reduce the air flow in and out, and the cooling effect will be poor. When cleaning the dust filter, first remove the dust filter according to the instructions, brush it with a soft brush dipped in neutral cleaning agent, rinse it with clean water, then dry it with a soft cloth or air dry it in a cool place. After that, close the dust filter according to the instructions. The internet
