How to operate the industrial chiller correctly, are you doing it right

The following are the points summarized by the editor on how to operate industrial chillers correctly and safely to share with you, I hope it will be useful to everyone!

　　 1. First of all, during the installation, we must check whether the industrial chiller is damaged, and choose a suitable place to facilitate installation and future maintenance.

　　2. The place where the unit is installed must be the floor, installation mat or foundation, whose levelness is within 6.4mm, and can bear the operating weight of the unit.

　　3. The unit should be placed in a computer room with a room temperature of about 5 degrees, and there should be enough space around and above the unit to allow the equipment to dissipate heat during operation and perform routine maintenance afterwards.

　　4. At one end of the unit, there should be a space for pipe extraction to clean the condenser tube bundle, and door openings or other suitable openings can also be used.

　　5. Select the water pipe with the appropriate pipe diameter, the cooling system and the cold water system when the unit is running at maximum power, and connect them accurately.

　　6. ​​For common applications, the water flow speed through the evaporator and condenser should be between 1.0-3.6m/s.

　　7. Under any load conditions, the water flow should be kept intact.

　　 8. The design and installation of all chilled water and cooling water pipelines should be carried out according to conventional methods, and the chilled water pump should be located on the inlet pipe of the unit to ensure the positive pressure and flow in the unit. When piping, damping pipes should be installed to ensure proper flexibility, and to prevent water from the evaporator from being drained when the pump is stopped.

　　 9. The pipeline should have a firm support independent of the industrial chiller to avoid stress on the components of the chiller. The hanger should be set to facilitate pipe alignment.

　　 10. In order to reduce noise and vibration, it is best to install vibration isolators on the pipeline.

11. In order to use industrial chillers economically and effectively, we recommend that water treatment experts analyze the quality of the water supplied to the evaporator and condenser. Poor water quality can cause scale deposits and affect heat transfer, or produce erosion and precipitation, breed organic matter, and affect the unit’s performance. Function, increase the cost of operation and maintenance.

12. Generally speaking, accurate water treatment and regular cleaning of the tube bundle can maintain its good performance. If the existing water quality cannot be improved by appropriate methods, then it is necessary to consider allowing the tube bundle to have a larger fouling coefficient or specify Special structural materials or water pipe inlets are equipped with filters and cleaned up on schedule.

　　13. After the leak test is completed, all nozzles must be rust-proofed.
