Because most refrigerators, ice makers, and freezers are constantly running, it is normal for these kitchen appliances to make up roughly fifteen percent of your building’s total energy bill. Such a significant percentage means that improving refrigerator efficiency will result in cost savings for your business.
Improving Refrigerator Efficiency
Installing an evaporative fan controller is a great way to reduce energy expenditure. Most current refrigeration systems use a motorized fan that is in constant operation as long as the machine is turned on. Running a fan like this actually works against the refrigerator because it produces heat. This means that a traditional fan not only uses energy constantly to stay running; the refrigerator uses more energy than necessary trying to cool itself as the result of the increase in heat.
Ultimately all of this extra work will lead to a premature breakdown of your refrigerator. An evaporative fan uses a high-efficiency motor that solves many of these current problems and can reduce energy consumption by as much as 40 percent. Such a high reduction in energy means that you can recoup the cost of the installation in less than a year.
Other practices can help reduce your refrigeration system’s energy consumption:
- Keeping up with maintenance and making necessary repairs quickly
- Keeping the refrigerator coils clean
- Upgrading to an Energy Star- certified, solid-door unit
- Turning off door heaters
- Using night curtains on any refrigerated display cases
