Since the air-cooled screw chiller uses a fan to dissipate heat, its installation and use environment must be in an open area with good air circulation. This will not only not affect the cooling effect of the air-cooled screw chiller, but also improve the work of the chiller. efficiency. The fan of the air-cooled screw chiller is installed on the top. Some customers choose to install it on the side of the chiller if they have special needs.

Causes and solutions for excessive fan noise:

1. The rotation speed is too fast: Reduce the rotation speed and check whether the fan noise is still too loud. If the noise is still too loud, you can only replace the fan with a new one.

2. Large gaps and worn parts: Adjust the gap to the appropriate position. Worn parts cannot be repaired and can only be replaced with new parts.

3. Valve flow is too high: adjust the valve.

4. Motor problems: Check whether there are problems with the motor and power supply, and solve them as soon as possible.

5. Lubricating oil: Too little lubricating oil or quality problem. Just fill the lubricant to the required position. If there is a lubricating oil quality problem, replace it with regular and qualified lubricating oil.

6. Bearing rupture: Contact the chiller manufacturer to replace the bearing with a new one.

7. Fan is clogged: Check the air inlet and outlet and clear the blockage.

If the heat dissipation effect of the air-cooled screw chiller is poor, the cooling capacity will also be insufficient, and it will also affect the manufacturer's requirements for chilled water.
