Are you Losing Costs Due to Energy Inefficiencies?
There are many ways to improve overall energy efficiency for commercial refrigeration and HVAC equipment.
Typically, 30% of the energy used to heat and cool a supermarket or commercial building is wasted. Wasted energy can be caused by; older outdated commercial refrigeration equipment, outdated refrigerants, leaks in the system, over-sized compressors and improperly installed commercial refrigeration units or HVAC equipment.
Refrigeration and HVAC techs can assist supermarkets with money saving improvements and preventive maintenance. They can catch smaller issues before a breakdown that could severely impact energy efficiency and your bottom line. Ultimately, a good place to start is to review your energy saving strategy and align it with your preventive maintenance plan. This should be consistent across store locations, so all maintenance members are aware of what plan is implemented.
6 Ways to Improve Energy Efficiency in Supermarkets:
1. Use Energy Efficient Lighting
Install LED and fluorescent fixtures – LED lighting lasts longer and consume less energy than incandescent light fixtures
2. Update System Technology
Use programable thermostats and modern control units to help optimize energy. Installing variable speed motors or a smart motor system to only run when needed can make an impact on your commercial refrigeration equipment.
3. Invest in Night Covers & Refrigerated Display Cases with Doors
Night covers for open refrigerator cases can reduce the daily load and keep products colder. While retrofitting open refrigerator display cases with doors may reduce the energy output of medium-temperature cases– putting less tension on the system.
4. Eliminate the Risk of Unchecked Leaks
Invest in preventive measures such as installing monitoring devices or injecting UV fluorescent dye. Having certain areas routinely checked and monitored will lower this risk. A more expensive option is to retrofit units with new refrigerants and upgrading to a more energy efficient compressor.
5. Plan Regular Maintenance on Refrigeration & HVAC Equipment
Schedule refrigeration equipment maintenance regularly to minimize clogged filters and leaks. These can cause strain on a system, forcing it to work harder and use more energy. Not to mention create discomfort for shoppers if not properly cooling.
6. Schedule an Energy Audit
Contact an energy expert to examine the commercial refrigeration system in the supermarket to perform an Energy Audit and identify poor energy usage. They can recommend what changes to implement.
