Frost buildup in refrigerators affects cooling efficiency and increases energy consumption. There are two types of scientific defrosting methods:
① Automatic defrosting (air-cooled refrigerators use heating elements to evaporate frost, which is hassle-free but consumes slightly more energy);
② Manual defrosting (which allows the refrigerator to defrost naturally after a power outage, allowing for clearing of accumulated water. This is suitable for direct-cooled refrigerators).
It is recommended to adjust the defrosting frequency based on frequency of use and ambient humidity: defrost immediately if the frost layer exceeds 5 mm; if humidity is high or the door is frequently opened, perform a weekly inspection. Air-cooled refrigerators can rely on the automatic mode. Be careful to avoid scratching the interior walls with hard objects during defrosting to ensure safety.
