Where to start
Businesses like groceries and restaurants spend heavily on energy for refrigeration. In fact, more than 50% of a large groceryís energy budget goes to refrigeration, and restaurants spend about 15% of their budget this way.
Choosing energy-efficient refrigeration equipment can help reduce utility bills dramatically, but thatís just the start. The newest refrigeration technology not only uses less energy, but it can improve performance and extend the life of the unit, making it easier than ever to control operational costs.
Where to look for savings
There are several common refrigeration applications, but the following list is an excellent place to start saving with energy-efficient systems and strategies.
- Grocery store refrigeration systems (their display cases and central refrigeration systems) use about one-third of the energy required for refrigeration by the commercial sector.
- Walk-in coolers and freezers account for about 18% of refrigeration energy use.
- Reach-in refrigerators and freezers are responsible for about 12% of overall consumption.
- Refrigerated vending machines consume about 13% of the sectorís refrigeration energy.
- Ice machines account for about 10% of refrigeration energy use.
There are significant opportunities for improving energy efficiency with a commercial refrigeration system. This chart shows an estimate of the savings potential for each technology with payback in five years or less.
