ENERGY STAR certified commercial refrigerators and freezers are more energy efficient than standard models. They also come with a variety of energy saving features that help save money on your utility bill. Keeping your refrigerator and freezer clean of debris can help prevent your food from spoiling. They should also be kept out of direct sunlight and other heat sources. In this way, they can provide the best possible cooling performance for your food.
Commercial refrigerators must meet strict energy efficiency standards to earn ENERGY STAR certification. The regulations require that commercial refrigerators be at least 15 percent more energy efficient than the minimum federal efficiency standard. These refrigerators also need to contribute to reducing greenhouse gases and polluting emissions.
To be certified to service commercial refrigerators, you must first complete refrigeration training. There are a variety of refrigeration training courses available online. You can start with the Fundamentals of Refrigeration course taught by Chris Compton and move on to advanced courses taught by Dick Wirz. Online refrigeration courses include recorded lessons covering refrigeration principles, evaporators, condensers, compressors, measuring devices and motors. The training also covers common service issues.
Commercial refrigerators and freezers must be serviced regularly to maintain optimal cooling performance for your business. Commercial freezers have a larger capacity than conventional refrigerators, and interior shelves made of commercial-grade materials are easy to clean and resistant to bacteria. These units also have adjustable temperature controls and built-in incandescent lighting.
