Save energy with cogged V-belts

May 28, 2015 | Posted in HVAC

Heating and cooling costs add up to approximately 12% of total commercial building electricity use1, so any plays to make HVAC systems more efficient can help businesses score savings that translate to real dollars on the bottom line. Cogged V-belts, also known as notched V-belts, can help businesses save 2-3% of energy used by HVAC systems using a standard smooth V-belt. DP&L recently announced a partnership with AEP Ohio, Midwest Energy Efficiency Alliance (MEEA) and Argonne National Laboratories in a pilot program to encourage local distributors to educate customers about energy efficient cogged V-belts.

The pilot program, which runs through October, is attempting to transform the market and move businesses toward the use of cogged V-belts, which run cooler, last longer and use less energy. Allied Supply, with locations in Dayton, Lima and Columbus serving DP&L customers, is the local distributor participating in the pilot program.

How can cogged V-belts help you save?

Belts are often used to transfer power from the motor to pumps and fans. Standard V-belt drives, the lowest-cost option, are found in the majority of belt applications. When new, V-belts typically achieve efficiencies in the range of 90 to 95 percent. A worn belt, however, can considerably reduce the efficiency due to slippage caused by slackening and worn grip surfaces.

Cogged V-belts are similar to standard V-belts, except that the normally flat underside has longitudinal grooves in it, allowing better grip and less slip than standard V-belts. This results in efficiency improvements of 2 to 3 percent over a standard V-belt.

Cogged V-belts are primarily used in HVAC applications, but are used in power train applications as well. According to the U.S. General Services Administration, businesses typically see a payback time of less than one year due to energy savings and reduced maintenance costs2.
