Is the quality of the freezer measured by the price of the freezer

People are used to the fact that the quality of any item is determined by its price. In many cases, the quality of expensive goods is not necessarily very good, but there are also some to make up the number. For example, in the refrigeration industry, is the quality of the freezer measured by the price of the freezer? In fact, in addition to the price of the freezer, there are many factors that affect the quality of the freezer, such as the environment used, whether it is regularly maintained, and whether it is cleaned up on time. In fact, the quality of the freezer is to determine whether the refrigeration effect of an freezer is normal. The main purpose is to check the temperature inside the freezer. If the temperature inside the freezer meets the requirements of the manual, the freezer is normal. Because the manufacturing process of the freezer requires that some parts do not have evaporation tubes, the parts here may not frost, and because the temperature in the freezer is gradually transferred to each position, the temperature in the freezer will reach the equilibrium state after a period of time, and the temperature difference between each part is not large, so the local frost-free or frosting amount cannot be used as the standard to judge the refrigeration of the freezer.

Now that we know that the price of the freezer is not the only standard, how can we judge the cooling effect? And if use is correct. At the same time, it is also important for users to master the correct use of the freezer. For example, the cold food in the cabinet should not be too full. There should be a gap between the cold food and cold food to facilitate the circulation of cold air. The freezer should be placed in a well-ventilated place without direct sunlight. Only correct use can ensure the normal operation of the freezer. Because most freezers do not have automatic frost function, it is necessary to disconnect the power supply, take out the food in the freezer, open the door cover, and slowly defrost. The defrosting time is long. You can put a basin of warm water at about 50 ℃ into the cabinet, cover the door cover, and heat it with warm water to accelerate the defrosting speed. The amount of frost inside the freezer is related to the humidity inside the freezer. For example, putting food with high moisture in the freezer or opening the door too many times can cause too much frost on the inner wall of the freezer. The more frost on the inner wall of the freezer is not the better, but the less frost is the better, because the heat transfer coefficient of the frost is low. If the thickness of the frost layer exceeds 10 mm above the ground, its cooling effect will be significantly reduced. Therefore, As a refrigerator, if the frost layer on the inner wall is more than 10mm thick, it should be defrosted. Once these can meet the user's requirements, it is basically a qualified freezer. So in the future, when you choose and buy refrigerators, you must not only look at the price, but also pay attention to the essential functions.
