How to Store Your Water Chiller Safely During Holiday Downtime

As the long holiday approaches, proper care for your water chiller is essential to keep it in top condition and ensure smooth operations when you’re back to work. Remember to drain the water before the holiday. Here’s a quick guide from TEYU Chiller Manufacturer to help you protect your equipment during the break.

1. Drain the Cooling Water

In winter, leaving cooling water inside the water chiller can lead to freezing and pipe damage when temperatures drop below 0℃. Stagnant water can also cause scaling, clogging pipes, and reducing the performance and lifespan of the chiller machine. Even antifreeze can thicken over time, potentially affecting the pump and triggering alarms.

How to Drain Cooling Water:

① Open the drain and empty the water tank.

② Seal the high-temperature water inlet and outlet, as well as the low-temperature water inlet, with plugs (keep the filling port open).

③ Use a compressed air gun to blow through the low-temperature water outlet for approximately 80 seconds. After blowing, seal the outlet with a plug. It is recommended to attach a silicone ring to the front of the air gun to prevent air leakage during the process.

④ Repeat the process for the high-temperature water outlet, blowing for about 80 seconds, then seal it with a plug.

⑤ Blow air through the water-filling port until no water droplets remain.

⑥ Drainage finished.

Note:

1) When drying pipelines with an air gun, ensure the pressure does not exceed 0.6 MPa to prevent deformation of the Y-type filter screen.

2) Avoid using an air gun on connectors marked with yellow labels located above or beside the water inlet and outlet to prevent damage.

3) To minimize costs, collect antifreeze in a recovery container if it will be reused after the holiday period.

2. Store the Water Chiller

After cleaning and drying your chiller, store it in a safe, dry spot away from production areas. Cover it with a clean plastic or insulation bag to protect it from dust and moisture.

Taking these precautions not only reduces the risk of equipment failure but ensures you’re ready to hit the ground running after the holidays.

How Does Refrigerant Cycle in the Cooling System of Industrial Chillers?

In industrial chiller cooling systems, refrigerant cycles through a series of energy transformations and phase changes to achieve effective cooling. This process comprises four key stages: evaporation, compression, condensation, and expansion.

1. 1. Evaporation:

2. In the evaporator, low-pressure liquid refrigerant absorbs heat from the surrounding environment, causing it to evaporate into a gas. This heat absorption lowers the ambient temperature, creating the desired cooling effect.

3. 
   

2. Compression:

The gaseous refrigerant then enters the compressor, where mechanical energy is applied to increase its pressure and temperature. This step transforms the refrigerant into a high-pressure, high-temperature state.

3. Condensation:

Next, the high-pressure, high-temperature refrigerant flows into the condenser. Here, it releases heat to the surrounding environment and gradually condenses back into a liquid state. During this phase, the refrigerant temperature decreases while maintaining high pressure.

4. Expansion:

Finally, the high-pressure liquid refrigerant passes through an expansion valve or throttle, where its pressure drops suddenly, returning it to a low-pressure state. This prepares the refrigerant to re-enter the evaporator and repeat the cycle.

This continuous cycle ensures efficient heat transfer and maintains the stable cooling performance of industrial chillers, supporting various industrial applications.

Industrial Chiller Winter Anti-Freeze Maintenance Tips

As the winter chill sets in, it's crucial to take extra care of your industrial chiller to ensure its longevity and optimal performance. Here are some essential tips to keep your chiller running smoothly throughout the colder months.

1. Add Antifreeze When Temperatures Drop Below 0℃

1)Why Add Antifreeze?——When temperatures fall below 0℃, antifreeze is essential to prevent freezing of the coolant, which could cause cracks in the laser and internal chiller pipes, damaging seals and affecting performance. It's important to choose the right antifreeze, as the wrong type could damage the industrial chiller's internal components.

2)Choosing the Right Antifreeze: Opt for antifreeze with good freeze resistance, anti-corrosion, and anti-rust properties. It should not affect rubber seals, have low viscosity at low temperatures, and be chemically stable.

3)Mixing Ratio: To ensure optimal performance and prevent damage, It's recommended that the antifreeze concentration does not exceed 30%.

2. Winter Operating Conditions for Chillers

To ensure proper chiller operation, maintain the environment temperature above 0℃ to avoid freezing and potential damage. Before restarting the chiller in winter, check if the water circulation system has frozen.

1)If Ice Is Present: ①Turn off the water chiller and related equipment immediately to prevent damage. ②Use a heater to warm the chiller and help the ice melt. ③Once the ice has melted, restart the chiller and carefully check the chiller, external pipes, and equipment to ensure proper water circulation.

2)For Environments Below 0℃: If possible and if power outages are not a concern, it is advisable to leave the chiller running 24/7 to ensure water circulation and prevent freezing. 

3. Winter Temperature Settings for Fiber Laser Chillers

Optimal Operating Conditions for Laser Equipment

Temperature: 25±3℃

Humidity: 80±10%

Acceptable Operating Conditions

Temperature: 5-35℃

Humidity: 5-85%

Do not operate laser equipment below 5℃ in winter.

TEYU S&A CWFL Series fiber laser chillers have dual cooling circuits: one for cooling the laser and one for cooling the optics. In intelligent control mode, the cooling temperature is set to 2℃ lower than the ambient temperature. In winter, it's recommended to set the temperature control mode for the optics circuit to constant temperature mode to ensure stable cooling for the laser head based on the user’s requirements.

4. Industrial Chiller Shutdown and Storage Procedures

When the ambient temperature is below 0℃ and the chiller is unused for a long period, drainage is necessary to prevent freezing damage.

1)Water Drainage

①Drain Cooling Water: Open the drain valve to empty all water from the chiller.

②Remove Pipes: When draining the internal water in the chiller, disconnect the inlet/outlet pipes and open the fill port and drain valve.

③Dry the Pipes: Use compressed air to blow out any remaining water. 

*Note: Avoid blowing air at the joints where yellow tags are pasted near the water inlet and outlet, as it may cause damage.

2)Chiller Storage

After cleaning and drying the chiller, store it in a safe, dry location. Use a clean plastic or thermal bag to cover the chiller to prevent dust and moisture from entering.
