What should be paid attention to when installing a chiller for cooling injection molding machines?
- Ventilation and heat dissipation: (Air-cooled chiller) Install in a well-ventilated and clean environment. Ensure that there is enough space between the air inlet and outlet (usually a certain distance is required in front, back, left and right according to the manufacturer's requirements) to avoid hot air backflow. High temperature environment will significantly reduce the cooling efficiency and reliability. (Water-cooled) Ensure that the cooling tower dissipates heat well.
- Pipeline design and insulation:
- Appropriate pipe diameter: Ensure flow and reduce pressure drop.
- Reasonable layout: Keep it as short and straight as possible and reduce elbows.
- High-quality insulation: Thorough and high-quality insulation of all chilled water pipes (especially those exposed to the environment) to prevent cold loss and condensation on the outer wall of the pipe is essential for energy saving and preventing moisture in the workshop.
- Horizontal placement and shock absorption: The chiller should be installed horizontally on a solid and flat ground, and shock-absorbing pads should be added if necessary. Avoid tilting operation to affect the life of the compressor and oil return.
- Power supply and grounding: Provide stable power supply (voltage, frequency, phase) that meets the requirements and ensure reliable grounding.
The benefits of using air-cooled chillers:
- No cooling towers.
- Better environmental stability-no water wastage.
- Low maintenance costs.
- Easier to operate and control-tower freezing and tower bypass absent.
- Chemical costs avoided.
- Water costs avoided, especially in cities.
