What is the system for defrosting a refrigerator?

No Frost literally means “no frost.” That is, during the entire operation of the device, no snow and ice build up on the inner walls of the refrigerator. Therefore, such a defrosting option, as for a classic refrigerator, is simply not needed for such a device. Why is this happening? It's all about the work of the unit itself.

Manufacturers of refrigeration appliances offer models with two types of defrosting: drip or crying and windy or No Frost. How profitable is the purchase of a LV Nou Frost refrigerator?

Drip thawing

With such a defrosting system, a flat evaporator that cools the rear wall of the chamber is located on its back side. When the compressor is operating, frost forms on this part of the chamber. Ice melts during breaks between freezing cycles, and water flows out of the chamber through special grooves into a container that is located near a warm compressor. Under the influence of warm air, it evaporates. This type of defrosting has refrigerators familiar to most people.

Wind defrost

No Frost type defrost is based on the circulation inside the air chamber. This is done thanks to a special built-in fan, which contributes to the even movement of cold air. An evaporator is integrated in the housing behind the rear wall outside the chamber. It is constantly blown with air, which is supplied by the fan through the air ducts. Moisture generated during operation of the unit settles on a cold surface. In between compressor operations, the frost defrosts and evaporates using a low-power heater. After that, the cycle repeats again.

Important! Manufacturers of eastern countries, such as Japan and Korea, equip both chambers of a household appliance with a wind defrosting system: freezer and refrigerator. This is due to the marine climate of Southeast Asia, because such a system is simply ideal for working in conditions with high humidity.

European manufacturers make refrigerators, both with full No Frost, and with partial. That is, only the freezer has a wind defrost, and the refrigerator compartment is equipped with a drip system.

Benefits of LV Fridges with No Frost

What are the main advantages of such units? Is it worth replacing a familiar appliance with an LJI Nou Frost refrigerator? - The instruction manual will help to understand this.

Consider the main advantages of equipment with a wind defrosting system:

• Such refrigerators have virtually no ice inside both compartments, which contributes to a significant increase in net volume.
• The walls of the chambers due to the operation of the fans are less wet, which reduces the risk of growth and development of harmful microorganisms.
• Maintenance of such appliances is simpler than drip-type refrigerators.
• After loading a new batch of products into the unit, the uniform temperature inside the chamber is restored very quickly. At the same time, the packages do not freeze to each other.
• For a longer preservation of the freshness of products, many refrigerators have special compartments with a temperature of about 0C in them, the so-called FreshZone.
• If the system breaks down, the device does not require shutdown. He will continue to fulfill his function until the arrival of the master.

Disadvantages of No Frost Refrigerators

Like any other equipment, devices with such a defrosting system have their drawbacks:

• Due to the constant flow of air in the refrigerator, the products dry quickly enough. This problem is solved by packing products in film or by placing them in containers.
• The system itself conceals a lot of space - about 20 liters per camera.
• Inexpensive refrigerators with such a system are characterized by additional fan noise. But now it is rarely possible to meet a model with this drawback.
• Such a system increases the cost of the refrigerator. Therefore, devices like No Frost are more expensive than drip units.

Important! You must understand that the system in no way affects the quality of freezing and storage of products, it is designed to facilitate the maintenance of the unit. Therefore, whether your convenience is worth the extra cash costs is up to you.
