How to extend the practical life of the refrigerator

Creating a cozy and peaceful summer home requires carefully selected appliances that enhance comfort without sacrificing style and efficiency. Appliances 4 Less Sugarland offers residents of Alvin, Conroe, Texas City, Galveston, and more a selection of opened, scratched, and dented appliances that are perfect for summer living. Here’s our guide to the must-have appliances for a cozy summer home.

As the core equipment of food preservation in modern families, the service life of refrigerators and freezers directly affects the quality of life and economic costs. Many users find that the equipment often has problems such as reduced cooling efficiency and increased noise after several years of use, which is often closely related to the lack of routine maintenance. Below, I'll show you a few tips to extend the life of your refrigerator.

1.Prevent hot food from being put in directly

When high-temperature food directly into the low-temperature environment, it will trigger a violent heat exchange process. According to the Second law of thermodynamics, this abrupt temperature gradient causes a surge of current at the start of the compressor, accelerating the aging of the coils. In addition, hot food will produce a large amount of water vapor during the cooling process. These water vapors will condense into small water droplets when they meet the cooler inner walls of the refrigerator. Over time, bacteria are likely to grow, may also let the refrigerator freezer internal mold, affect the cooling effect. Therefore, such as hot food slightly cool, the temperature dropped to room temperature or so, and then placed in the refrigerator or freezer, is the best practice.

2.Lubricate moving parts

The directional wheel at the bottom of the refrigerator and the universal wheel at the back of the refrigerator are like the toes of two dancers, carrying the dual mission of equipment mobility and stability. And door body hinge is their open and close“Joint hinge”. It is recommended to lubricate refrigerator roller bearings quarterly with edible grade mineral oil, and to remove embedded stones of cast iron cast iron gimbals of refrigerators with soft brushes before spraying antirust lubricant. For hinge parts, the refrigerator door seals need to focus on processing near the shaft, the refrigerator is to pay attention to the top of the heavy-duty door pressure bearing. Regular maintenance can make both opening and closing smoothness increased by 60% , to avoid Cottonwood caused by the door seal tear.

3.Dust removal by heat sink

Remove the grille on the back of the refrigerator and the grille on the bottom, and you'll see two sets of densely packed fins-their 'breathing systems. ' . When dust covers more than 0.5 mm thick, the refrigeration efficiency of refrigerators will drop by 18% , freezers may be due to poor heat dissipation trigger overheating protection.

Cleaning should pay attention to: refrigerator condenser should be cleaned from top to bottom, to avoid dust falling into the compressor room; refrigerator is required to use vacuum cleaner with narrow suction head, focus on cleaning the bottom return air. For built-in freezers, dust should be removed monthly with a Compressed air tank.

4.Drain Hole and sink dredge

The drain holes in the refrigerator compartment and the defrosting sink at the bottom of the freezer make up the“Urinary system” of the cold chain equipment. When the refrigerator drain hole is blocked by food residue, it will cause the wall to freeze and thicken. If the bending radius of the freezer sink drain pipe is too small, it may cause water to accumulate on the ground of the freezer room. Warm water can be injected into the syringe to soften the ice block, and then insert a thin plastic hose (refrigerator with a diameter of 3 mm, refrigerator with 5 mm) rotating dredge. For the refrigerator, you need to check the drain every six months to ensure that no u-bend, if necessary, can be wrapped with insulation cotton exposed pipe section.

Conclusion

The refrigerator freezer is in our life indispensable good helper, it for we preserve food, bring convenience. As long as we master these simple longevity techniques and maintain them regularly, we can keep them in good working condition and with us for longer. Let us use these small actions, to express the love of the refrigerator, let it continue to add warmth and convenience to our lives.
