Keep away from heat sources and maintain adequate space.
For every 5°C increase in the ambient temperature around the refrigerator, its internal energy consumption increases by 25%. Therefore, it should be placed away from heat sources, ideally in a well-ventilated and shaded area. Do not place hot food directly into the refrigerator; allow it to reach room temperature first. Food in the freezer compartment should ideally be packaged in small plastic bags for quick freezing, preventing it from drying out and turning into frost. Food should not be packed too full; leave space between the food and the refrigerator walls to allow for air circulation. Frozen food should be transferred to the refrigerator compartment to thaw before consumption.
Avoid frequent door opening.
Frequent door opening significantly increases the refrigerator's energy consumption and reduces its lifespan. Because the refrigerator door is large, frequent opening allows cold air to escape while warm, humid air enters, raising the internal temperature. Simultaneously, the humid air entering the refrigerator accelerates frost formation on the evaporator surface, resulting in a thicker frost layer. Because the thermal conductivity of frost is much lower than that of the evaporator material, it hinders heat conduction, resulting in a slower temperature drop inside the refrigerator, increased compressor operating time, accelerated wear, and increased power consumption. If the frost layer on the evaporator surface is thicker than 10 mm, the heat transfer efficiency will decrease by more than 30%, causing a significant reduction in cooling efficiency. Furthermore, when the refrigerator door is opened, the interior light turns on, consuming electricity and dissipating heat, which is clearly detrimental to energy conservation.
Power Outage Preservation and Off-Peak Electricity Use
If you are concerned about power shortages during peak hours, it is recommended to use a refrigerator with "time-of-use electricity metering and power outage preservation" functions. Such refrigerators can still cool and preserve food even during power outages or sudden power cuts lasting up to 20 hours; moreover, their "time-of-use electricity metering" function can avoid cooling during peak electricity hours when electricity prices are high, automatically achieving "off-peak electricity use."
