Refrigeration equipment for businesses such as grocery stores, convenience stores, and restaurants typically account for 25% to 60% of electricity consumption. Fortunately, there have been many advances in commercial refrigeration technology — many of which are extremely cost effective with improved product quality.
Your facility's size and type, and the needs of your business may determine the type of refrigeration system used.
Central refrigeration systems consist of refrigerated spaces connected to a remote condenser. These systems have the advantage of emitting waste heat outside of the conditioned space through the condenser.
Stand-alone refrigeration systems, often called merchandisers, usually have the case, evaporator and condenser packaged in a single unit, similar to your home refrigerator. These stand-alone units are commonly used in smaller facilities where a central refrigeration system is not justified.
There are many other efficiency opportunities in refrigeration. When working with a contractor or service provider, ask them to review and specify additional efficiency measures, such as:
