After hundreds of years of development, the refrigerator has undergone tremendous changes in terms of form, performance and function. Despite the huge changes in products, the important criterion for measuring the actual value of refrigerators is storage space.
With the increasing consumer demand, users' demand for refrigerator storage space is getting higher and higher, but it is an indisputable fact that the growth rate of refrigerator storage space is far less than the growth rate of the whole machine volume. Why is there such a situation? Appeared? Who stole the storage space that should belong to the refrigerator? With questions we walked into today's content.
In order to let consumers more clearly understand the change range between the storage space of the refrigerator and the volume of the refrigerator, we selected a number of products from three different sections of 281L-450L, 451L-560L and 561L from Jingdong Mall for parameter comparison.
In order to let everyone more intuitively feel the relationship between the refrigerator volume and the refrigerator volume, we have converted the refrigerator volume by unit, that is, the refrigerator volume = depth * width * height, 1 cubic meter = 1000 liters.
Figure: Variable table of refrigerator volume and refrigerator volume of three mainstream refrigerator brands in Jingdong Mall
From the above table, we can see that the volume converted from the refrigerator volume is far from the actual volume of the refrigerator. From this point of view, the huge data gap is not explained by the space occupied by components such as internal compressors and evaporators in the refrigerator. In order to better display the volume change of the refrigerator, we have made the following table.
Schematic diagram of the volume change of the refrigerator volume and refrigerator volume of the three major refrigerator brands
It is not difficult to find through the above two charts that as the volume of the refrigerator increases, the volume of the refrigerator will increase to a different extent. However, in the "three major mainstream refrigerator brand refrigerator volume and refrigerator volume curve change schematic", the curve changes of the three brands are different, some rise gently, and some increase rapidly, especially in the same refrigerator volume, the volume of the refrigerator It is also different, so what is the cause?
In fact, in the case of the same volume of the refrigerator, the reason why the volume of the refrigerator is greatly deviated is mainly due to the difference in the material of the foaming agent used for the heat preservation function of the refrigerator. The following table is a common foaming agent material for the refrigerator.
Main material of refrigerator insulation foaming agent
For the majority of users, refrigerator insulation and insulation materials are often the most overlooked problems when purchasing refrigerators. It is understood that insulation and insulation materials have a direct impact on the refrigeration and preservation of refrigerators. The thicker the insulation layer, the better the insulation effect and the lower the power consumption. However, the problem is that as the thickness of the insulation layer increases, the overall volume of the refrigerator will also increase. If the volume of the refrigerator is not increased, the storage capacity inside the refrigerator is bound to decrease. This is obviously unacceptable for the current price of housing, so is there any other way to solve this problem?
The answer is definitely there. Next, we will show you the real shots of the inner walls of the two refrigerator products.
Figure 1: Thin-walled refrigerator
Figure 2: Thick-walled refrigerator
Through the above real shots, you can clearly see that the gap between the thickness of the refrigerators of the two products is very large. If you follow the introduction above, there will definitely be a significant gap between the insulation effects of the two products, but what about the facts?
Figure 3: Temperature curve of a thin-walled refrigerator
Figure 4: Temperature curve of thick-walled refrigerator
As shown in the figure, there is no significant difference in the insulation performance of the two products with different thickness of the refrigerator wall. What are the reasons? The main reason is that many companies use more scientific and advanced insulation materials to make the outer wall of the refrigerator. The most insured technology that is sought after by enterprises is vacuum insulation technology.
Manual fixed vacuum heat-breaking material process
Due to the higher thermal insulation properties, refrigerators with vacuum insulation materials are more energy efficient. Unlike most insulation materials, the vacuum insulation material is relatively thin, so the refrigerator wall using the material can be made thinner and can provide a larger internal volume of the refrigerator in the case of an external volume equivalent.
It is precisely because of the addition of these technologies that the physical properties of the refrigerator insulation layer are strengthened, thereby improving the insulation effect of the refrigerator while effectively reducing the thickness of the refrigerator wall. As a result, there is no longer any need to worry about the storage space of the refrigerator being ruthlessly stolen.
