< ' , b ' Precautions for purchasing a refrigerator:
'
'. There is a sticker on the refrigerator Some label analysis:
Power consumption and energy efficiency ratio signs. You can just ignore these two goals and ignore them. You will only know the actual energy efficiency after using it. Some refrigerators are marked with .3. If you believe that such a large refrigerator can use so much electricity in a day, you will not be able to use superconducting skills. ambiguity can be achieved.
Input power. If the input power is too small, the refrigerator compressor will not stop for a long time, which is the so-called small horse cart. This is similar to the selection of air conditioners. This indicator can be found on the nameplate on the back of the refrigerator body. The higher the power input, the better, especially for large-capacity refrigerators. For example, Meiling's two refrigerators have only one compressor power, but smaller compressors have more power. This is like installing one in a square house. The air conditioner is installed in another square room. Comparison of the functions of air conditioners.
Compressor brand and whether it is imported. Like air conditioners, the quality of the two units (condenser and evaporator) directly affects the function of the product, not the compressor, and many imported compressors are of poor quality. Nowadays, there are several major domestic brands such as Embrak, Gasibella, Zanussi, Panasonic, and Samsung.
Freezing ability. Compared with special needs such as commercial, medical, and scientific research, the target reference of household refrigerators has little meaning. The Bosch model I bought has a kilogram of freezing capacity, which seems a bit funny now.
Climate type. According to the operating climate and ambient temperature of refrigerators in China, they are divided into subtemperate type, the ambient temperature is ℃, temperate type, the ambient temperature is ℃, subtropical type, the ambient temperature is ℃, tropical type, the ambient temperature is ℃.
The insulation layer of the refrigerator is even more difficult to understand. The insulation layer can be either thick or thin. For example, the insulation layer of Boshi refrigerators is exaggeratedly thick, while the insulation layer of Panasonic and other Japanese refrigerators is exaggeratedly thin. This has been debated in the forum. I think the main thing is to look at the foaming layer materials and technology. Foaming materials include - and cyclopentane (), and vacuum materials (which have better effects than traditional foaming layers), etc. Due to the impact of old fluorine-containing foaming agents on the environment (it is not toxic to the human body, and its performance and safety are better than today's cyclopentane, but it is just because of environmental issues), the Montreal Protocol stipulated that it should be implemented in developed countries in 3 years. Screening, while developing countries can be extended to the year. Pentane series has excellent environmental performance, is cheap and easy to obtain. Cyclopentane has become popular in European and American countries and is also the trend of refrigerator foaming agents in the future. It can be seen that some mainstream domestic brands are still using the old foaming materials, but selling them at high prices. It is too common for selected products to be sold at high prices in the Chinese market. When purchasing a refrigerator, we might as well pay attention to the foaming agent materials of the refrigerator and compare them. Take a moment, so you have an idea in your mind. The main refrigerator foaming materials are as follows (for ozone consumption capacity).
. Evaporator
(In the freezer, open the rows of tubes in the drawer box)
Try using a magnet. If it can be attracted, discard the refrigerator immediately. Nowadays, the market is full of Bondi pipes, which are double-sided copper-coated coil-welded steel pipes. They are products that reduce costs. There are not many aluminum pipes in the market today. So if you don't want to use magnets, you can only buy an air-cooled one, because you can't see its evaporator.
Count how many roots there are in each row. Nowadays, the market is dominated by roots. Some have roots/roots, and many have roots (roots have basically disappeared from the market). Naturally, the more the better, the higher the density. , it shows that the heat absorption area is large and the cooling capacity is good. Under the same material and the same quantity of evaporation tubes, the wire tube evaporator has better performance (and higher cost) than the plate tube evaporator. However, because there are many Bondi tube wire tube evaporators in the refrigerator now, and the quantity simply cannot meet the requirements. , The thermal conductivity of aluminum is larger than that of iron, so it is still recommended to use aluminum tube plate and tube evaporators.
In recent years, due to the price of aluminum materials, aluminum plates have become thinner and thinner, and their strength is slightly insufficient. Compared with wire tube evaporators, plate tube evaporators (poor contact between tubes and plates) are more likely to cause large ice formation in the refrigeration tubes. It is difficult to pull out the drawer. It cannot be denied that Haier is the most successful domestic refrigerator company in using Lock rings. Other refrigerator manufacturers have to switch to welding due to the high leakage rate of Lock connections (the cost is relatively high). . If the coating of the wire tube evaporator is scratched, it is easy to rust, so sliding parts such as drawers are generally not in direct contact with the evaporator.
The evaporator will feel obviously cool after being turned on for a long time. A short time indicates that the evaporator is highly efficient. This is usually difficult to estimate in the market.
3. Condenser
First determine the location of the condenser. Direct cooling is usually located on the sides and back. Air-cooled refrigerators are usually located at the rear of the refrigerator, a bit like the outdoor condenser of an air conditioner.
< ' , b ' ! Touch it bit by bit with your hands: first touch, how long will it take after turning on the machine to clearly feel the heat? Second touch, whether the heat is uniform and how large the area is (some manufacturers cut corners and the condensation pipes are loosely placed) , so the heating is very uneven). Only when the condenser area is large and the temperature is high can the heat in the refrigerator be emitted.
