Refrigeration
Save 10% - 25%
- Increase set points. Do not set temperatures lower than necessary.
Increasing the set points by one degree can save five percent running
costs.
- Install electronic expansion valves. Installing electronic
expansion valves on refrigeration plant can save up to 20 percent, by
varying the refrigeration cycle to match that of the load on the
refrigeration plant.
- Organise your fridges. Ensure material is not stacked in front of vents of fans.
- Keep condensers clean. Keeping condensers clean ensures an
adequate supply of clean cold air, which makes the chilling process
more efficient.
- Maintain refrigeration. Check the system routinely to ensure
that there is sufficient refrigerant change that there is o refrigerant
leakage. An undercharged system will cost more to run and may not
maintain consistent temperature.
- Upgrade your equipment. Energy efficient ice machines can save 6 percent on energy costs; vending machines and beverage merchandisers can save 9 percent; reach-in refrigerators can save 12 percent and reach-in freezers can save 16 percent.
