Commercial freezers are commonly used in a variety of settings, including large hotels, supermarkets, small cold drink shops, fast food chains, convenience stores, and more. These freezers serve an important purpose in commercial establishments, but their energy consumption should not be overlooked. To reduce the energy usage of commercial freezers, it is important to follow some precautions while using them. A reasonable selection of freezer models is crucial. Various models of freezers have different powers. Choosing a freezer that meets your needs can help reduce energy consumption. For example, if you need to store a small number of products, you can choose a cooler with lower power to achieve energy-saving goals. The key to keeping

First: The difference between Air cooling and Direct cooling: Air-cooling refrigerators use frost-free technology for refrigeration. The principle is to use an internal circulation fan to disperse cold air to all corners of the refrigerator which can make the temperature smooth. This design prevents the air-cooling refrigerator from generating frost, thus preventing food from frosting. Direct cooling refrigerators cool down the temperature through the internal evaporator directly contacting the air in the refrigerator compartment. Therefore, direct cooling refrigerators require regular defrosting operations to ensure normal operation of the refrigerator. Second: Advantages and disadvantages of air cooling and direct cooling: Advantages of air-cooling refrigerators: 1. The internal temperature is more uniform and accurate than a direct cooling refrigerator, which is conducive to the preservation of food; 2.
