How to maintain industrial chillers in winter?

The maintenance of industrial chillers in winter is particularly important, because the low temperature environment will have a certain impact on the operation of the equipment. The following are some suggestions for the maintenance of industrial chillers in winter:

1. Check antifreeze measures

Antifreeze of cooling water system: If the cooling system of the chiller uses water as the cooling medium, be sure to ensure that the water will not freeze in winter. You can use antifreeze or add appropriate antifreeze to prevent water pipes from freezing and causing equipment damage.

External pipe insulation: For exposed pipes, insulation materials can be added to reduce the direct impact of low temperature on the pipes.

2. Clean the condenser and evaporator

Before using in winter, check whether there is dust, oil or debris on the surface of the condenser and evaporator. If there is, it needs to be cleaned to ensure that the heat exchange efficiency is not affected.

Clean the filters and heat exchangers in the system regularly to prevent scaling and clogging.

3. Check the compressor and electrical system

Compressor oil level: Check the oil level of the compressor oil, confirm whether the oil quality is normal, and replace it as needed.

Electrical wiring: Check whether the electrical wiring is tight to prevent poor contact or electrical failure.

4. Monitor system pressure and temperature

In low temperature environments, the pressure of the chiller system may change, and it is necessary to regularly check whether the refrigerant pressure is normal.

Check whether the temperature control system is operating normally and ensure that the temperature setting is reasonable.

5. Prevent cooling water from freezing

In low temperature environments, ensure the fluidity of cooling water. If the cooling water stops flowing for a long time or the temperature is too low, freezing may occur. Consider using a water pump to circulate the water flow regularly to avoid the water temperature being too low.

6. Add antifreeze or replace refrigerant

Depending on the type of chiller, check the use of refrigerant in a timely manner to ensure that its concentration, quantity and performance meet the standards. Insufficient refrigerant may cause poor system operation.

If water is used as the cooling medium, consider replacing or adding antifreeze before winter to prevent the cooling water from freezing.

7. Avoid long periods of non-use

If the chiller is not running for a long time in winter, consider starting it regularly and running it for a period of time to avoid the system being in a static state for a long time and causing failure.

8. Check the external environment

Keep the environment around the chiller clean and free of debris. Avoid freezing of the chiller surface due to cold weather, and keep the air flowing to help the equipment dissipate heat.

9. Regular inspections

In winter, conduct regular inspections of the equipment to ensure that all components are working properly and prevent malfunctions caused by cold weather.

10. Use thermostats

You can install thermostats to monitor the ambient temperature and ensure that the working state is automatically adjusted when the outside temperature is too low to avoid equipment damage.

Maintaining industrial chillers in winter can not only extend the service life of the equipment, but also ensure efficient operation of the equipment in cold seasons. If conditions permit, it is best to conduct a comprehensive inspection every quarter.Jialis machinery is a professional industrial chiller manufacturer from China with 15 years experience,Whatsapp+86-14748203674,Email:Johnny@jlschiller.com.
