Removing Non-Useful Energy Consumption Compressed Air
Facilities that have compressed air systems as part of their operation may want to look into these possible issues:
- Equipping your air compressor with a shut off valve could allow the compressor to be isolated from the compressed air network, thus, eliminating leakage and standby losses during non-operational hours.
- Check psi settings, these are sometimes set to higher pressure than is required because of leakage in their air compression system. Installing a receiver close to the working equipment so the air compressor set point can be reduced may help save energy. Receivers act as a buffer and storage medium between the primary compressor and the working equipment.
Energy Efficiency Upgrades
Compressed Air Ducting
If your air compressor’s intake is drawn from indoor, the ambient air temperature surrounding the air compressor is much higher than outdoor air temperature. Installing an air duct so that air is drawn in from outside can help reduce energy consumption. Cooler air is denser allowing it to compress easier and reducing total heat generated during compression.
Verify that the pump is correctly sized for the pool’s usage. Using an oversized pump for a pool can result in higher than necessary electrical consumption. If a pool water filter pump operates continuously, a variable frequency drive (VFD) could also be added to the existing pump motor to slow down the speed of the pump. A turbidity meter could be combined with the VFD to further increase the filter pump’s efficiency.
