Modern household models of refrigeration units are significantly different from those that frosted a lot of ice and required frequent defrosting. Their differences in some parameters are substantial enough. Let's figure out what is best to choose - a refrigerator with drip defrosting system or with no frost system.
Main characteristics
Refrigerators with both defrosting systems are popular - know frost and drip. To make a choice, you should know the features, as well as the pros and cons of these models.
No frost
The advanced no frost technology has made it possible to produce refrigerators that do not require defrosting at all. Such refrigerators have a freezer and a refrigerator, as well as an evaporator and compressor. Cold air is constantly circulating thanks to the fans.
Uniform product cooling
The even distribution of cold air leads to the fact that ice practically does not form, allowing the maximum use of the useful volume of the device. In this case, the products receive uniform and rapid cooling.
For your information! To maintain maximum nutrients, almost all models are equipped with a special compartment with a constant temperature of 0 degrees.
There is no frost and freezing of ice in the chamber. Periodically, the fan stops working, at this time the heater starts, which defrosts the frost from the evaporator. The resulting water flows through special inclined systems into a container located behind the unit. There, the liquid simply evaporates, you do not need to remove it.
The principle of the drip system
Devices with such a system of work are very popular. The evaporator located on the rear wall cools the internal chambers. During its operation, moisture accumulates, which flows through a hole at the bottom of the refrigerator into a special container.

If the compressor is active, moisture can freeze, forming ice.
Harm of the know frost system: myths and reality
There are many myths and speculations about the no frost system.
Myth # 1: Health Hazards
The most common is the health hazard of such a system. This statement has no foundation. Equipment (compressors, etc.) in refrigerators with no frost uses the same as in devices with a drip system. The refrigerants in them are also the same.
Air flow
Myth # 2: Overdrying Foods
It is widely believed that the know-frost system overdries products. There is some truth in this statement. Continuous fan operation, which provide air movement through the chamber, accelerates the drying and oxidation of already chopped and cooked food. To preserve the products, it is necessary to cover them with cling film or store them in closed containers.
Myth number 3: defrosting is not needed
The instructions for the refrigerator of the no frost system indicate that the device works efficiently and without defrosting. In this case, it is advisable to turn off the refrigerator once a year in order to carry out a general cleaning in it.
Myth number 4: there is less space inside the no frost refrigerator than in a drip of the same size
This statement is true.Due to the nature of the device, the internal volume of the no frost refrigerator is slightly smaller. In order not to make a mistake with the choice, the dimensions of the cameras should be examined before purchase.
Comparison of two systems
To determine which refrigerator is better - with the frost or drip know system, it is recommended to analyze the table below.
| Characteristic | Refrigeration system | |
| Drip | no frost | |
| Price | Affordable | High |
| Assortment of models | Big | Not so big |
| The size of the cameras and their capacity | More | Smaller |
| Power consumption | More economical | Less economical |
| Noise | Silent work | Louder |
| Defrost | Is required | Seldom |
| It takes a long time to restore the temperature | Yes | Not |
| The temperature at the top and bottom is different | Yes, from 4 to 8 degrees | Not |
| Uniform temperature distribution across all compartments | Not | Yes |
| The complexity of the cooling mechanism | Low | High |
| Freezing speed | Average | High |
| Condensation on the back | Yes | Minimal |
Selection recommendations
- It is necessary to foresee a set of containers for storing products. Especially advice is relevant for refrigerators with the no frost system.
- At least once a year, thorough cleaning must be carried out in the refrigerator, regardless of its operating system.
- The noise level, energy saving class and capacity of the device must be taken into account.
- Additionally, you can study the rating of the best models in the desired price category.
Wet cleaning must be carried out.
On which model to choose, everyone determines based on personal preferences. No frost will cost more, but will create additional convenience. In addition to the price, other parameters should be considered. Each model has its pros and cons, so it is important to study all the important characteristics beforehand.
