Since the advent of electricity, our lives have become much richer and more diverse. Now, almost every household is filled with appliances such as refrigerators, washing machines, televisions, and air conditioners. With the increasing number of appliances we use, electricity bills have become a major concern, especially during holidays when power consumption skyrockets. Below, we'll discuss methods for saving electricity in convenience store refrigerators.
Surveys have found that many retailers, fearing higher electricity costs, are hesitant to stock their refrigerated display cases with too much food. This is incorrect. It's not that storing less food automatically saves electricity; rather, the key is to store a reasonable amount, generally around 80% full.
Before buying a refrigerator, you should determine the required capacity. Vegetable display cases are typically measured in effective liters. Assuming each family member needs 60-80 liters, a small single-door refrigerator is sufficient for working professionals, as they don't store much food. Families shouldn't be greedy and buy large refrigerators like three-door or side-by-side models; choose a size appropriate for your family's needs.
Furthermore, the placement of the kitchen freezer also affects power consumption. If the temperature around the freezer increases by 5°C, its internal power consumption will increase by 25%. Therefore, beverage freezers should be placed in well-ventilated, shaded areas away from heat sources.
During use, commercial freezers should be opened for short periods, and food should be taken out and placed in the freezer quickly. In case of a power outage, do not open the freezer door temporarily to prevent cold water leakage. Hot food should be cooled down before being placed in the fruit freezer, otherwise it will increase the freezer's power consumption. Food should not be overfilled; leave gaps between the food and the freezer walls to allow for air circulation. Frozen food should be thawed in the refrigerator before consumption.
Finally, freezer maintenance and cleaning are crucial. Fresh food freezers may develop frost over time. Since frost is a poor conductor of cold, the freezer compartment of milk freezers should be defrosted regularly. After cleaning, the freezer should be dried before powering on to prevent immediate frost formation. Regularly cleaning the dust off the compressor condenser can maintain cooling efficiency and extend the lifespan of the freezer.
