Upright freezer air cooling frost-free technology

Creating a cozy summer home that serves as a peaceful retreat requires careful selection of appliances that enhance comfort without compromising on style or efficiency. At Appliances 4 Less Little Rock, we cater to residents in Little Rock, Benton, Conway, and Pine Bluff with an array of open box, scratch, and dented appliances that are perfect for elevating your summer living. Here’s our guide to the essential appliances for a cozy summer home.

In the Grand Narrative of life, the freezer is like a silent guardian of the time messenger, freeze the fresh food, continue the warmth of life. However, the traditional freezer frosting illness, but like haze, cover this beautiful. Nowadays, cheap vertical freezer with air-cooled frost-free technology amazing debut, it is not only a major breakthrough in science and technology, but also a deep commitment to the quality of life. This technology like a key, open efficient, convenient fresh new era, let us in the busy life, no longer need to worry about defrosting, can enjoy every fresh, feel the infinite charm of the integration of technology and life.

Ⅰ.Forced circulation duct system

Air-conditioning cycles in conventional freezers, like old highways, are congested and inefficient. After the air-conditioning generated, slowly spread out in the cabinet, resulting in different areas of temperature differences, the upper cold frostbite ingredients, the lower is not cool enough. A forced-circulation air duct system creates a high-speed runway for air-conditioning. It usually uses multi-fan cooperative work mode, in the refrigerator top, side position such as reasonable layout of fans. When the refrigerator starts, the fan runs at a high speed, and the cold air is transported to every corner of the cabinet quickly and evenly. Cold air from the air outlet after the Spout, along the well-designed air ducts, spiral downward flow, forming a three-dimensional cycle. This cycle is like putting an air blender inside a freezer, allowing air conditioning to cover every layer of food, greatly improving the temperature uniformity of the freezer and keeping the temperature difference to a minimum, ensure that all ingredients are treated equally.

Ⅱ.Optimization design of evaporator

Evaporator is the heart of air-cooled frost-free technology, its design directly determines the defrosting effect. Most of the traditional evaporators are flat plate type, the heat transfer area is limited, and the frost layer is easy to accumulate. The evaporator of a vertical freezer, on the other hand, has an l-shaped wraparound design, like a cooling vest. The aluminum fins are arranged closely, the heat transfer area is 2.3 times larger than the traditional design, and the frost layer growth rate is 58% slower. What’s more, the surface of the fin is coated with a nano-hydrophobic film, and the condensed water rolls into water droplets as soon as it hits the surface, which slide off like dew on a lotus leaf, giving the Frost no chance to take root. Even if occasionally a small amount of frost formation, but also in the subsequent automatic defrosting process quickly melt, to ensure that the evaporator always maintain efficient working condition.

Ⅲ.Automatic defrosting mechanism

Sensors inside the freezer monitor the thickness of the frost in real time after a period of time. Once the frost layer reaches a preset threshold, the system will automatically start the defrosting process.

1. Detection of frosting signals: the frosting on the evaporator surface is monitored by a temperature sensor or a time controller, and the defrosting process is triggered when a preset threshold (e.g. , low temperature duration or frost layer thickness) is reached.

2. Shut down the refrigeration system: Stop the compressor operation, shut off the refrigerant cycle, to prevent defrosting caused by continuous input of cold air efficiency.

3. Start the heating element: open the electric heating pipe or hot gas bypass valve to deliver heat to the evaporator surface, so that the frost layer gradually melt into water.

4. Drainage and ventilation: the melted water is discharged through the drain pipe, and the fan may run briefly (depending on the design) to speed up the air flow and avoid secondary freezing of the residual water.

5. Resume refrigeration mode: after detecting the frost layer completely melted (such as through the temperature recovery or timing end) , restart the compressor, the system to resume the refrigeration state.

Conclusion

Vertical freezer with air-cooled frost-free technology, played for us a fresh science and technology movement. It is an innovative force to dispel the haze of frosting in traditional freezers, making preservation easy and efficient. This technology is not only the progress of science and technology, but also the care and protection of the details of life. It shows us that technology isn’t just out of reach, but is actually being incorporated into our lives to enhance our happiness.
