A, refrigeration
Ninety percent of consumers enter the store after the first will ask the refrigerator performance issues. And this cooling effect has a lot to do with its refrigeration method. Which refrigeration method used by the current refrigerator refrigeration method is divided into direct cooling, air-cooled, wind direct cooling three ways.
1, direct cooling, also known as frosty refrigerator, using natural evaporation heat absorption, so that the hot and cold air in the natural circulation inside the box. This method has a rapid cooling, low noise, low production costs. However, the disadvantage is that the temperature at the refrigeration tube (freezer inside the refrigerator) is low, such as placed in the case of more storage objects to affect the circulation of cold air, which will lead to uneven temperatures inside the refrigerator box, and frozen vegetables on the moisture, then it will be frost. Currently on the market, all brands such as Siemens, Haier, Bosch, Panasonic, Rongsheng, etc. have launched the use of direct cooling method of refrigerators, the price point from 500 yuan to 6,000 yuan of products are sold.
2, air-cooled, also known as frost-free refrigerator. Refrigerators using this cooling method through the built-in fan will be cooled by the cooling tube to create a cold air circulation blowing, can avoid the frost problem brought about by the direct cooling method, but the higher cost, higher power consumption, complex structure is not easy to repair become the shortcomings of the air-cooled refrigerator. Unlike direct-cooled refrigerators, there are not many low-priced refrigerators on the market that use air-cooling, but Panasonic, Haier, Hisense, Midea, and Konka brands have launched related products.
3, wind direct cooling hybrid. Direct cooling and air-cooled two cooling methods have obvious advantages and disadvantages, so the refrigerator brand launched a high-end refrigerator products tend to use the wind direct cooling hybrid technology, such as the freezer room for direct cooling, can be quickly frozen to lock the water, to avoid the loss of food moisture, and the freezer room is used in the air-cooled, able to keep vegetables and other storage items frozen, do not have to suffer for the frost. The complete cooling system of the compressor refrigerator is composed of the compressor, condenser, anti-dew tube, capillary tube, evaporator filter drier, refrigerant and connecting piping. We are here mainly mainly introduced is very concerned about the compressor and condenser two parts.
Two, the compressor
Mainly crankshaft, piston, cylinder, rotor, body and other components. Currently on the market the mainstream compressor brands are Zanussi compressor, Embraco compressor, Toshiba Carrier compressor, Panasonic compressor, Hitachi compressor, LG compressor and domestic Haili compressor, Gasparilla compressor. In addition, a refrigerator refrigeration is good or bad with the refrigerator box insulation materials, insulation, door seals and internal air duct design has a close relationship. Although the compressor is the key to refrigerator refrigeration, but the average consumer in the purchase of refrigerators do not have to pursue the brand of the compressor, the purchase of the refrigerator to observe the overall design capabilities.
Three, condenser
The same brand of different positioning of the refrigerator products will be used in different forms of condenser, the current market condenser is mainly used in bonded tube or galvanized copper tubes, divided into external condenser, built-in condenser, the advantages and disadvantages of its different.
1, external condenser. External condenser hanging in the back of the refrigerator, the overall appearance of the refrigerator will have some impact on the design, and in the placement of the refrigerator with external condenser needs to be a distance from the wall to ensure that the heat dissipation performance is good. However, the advantages of external condenser are simple process and good heat dissipation.
2, built-in condenser. Built-in condenser is divided into the box on both sides of the installation method and back installation method, in which the box on both sides of the built-in condenser high cost, process complexity, but the heat dissipation area is large, intelligent effect, and beautiful appearance. Back mounted built-in low cost, beautiful appearance, but the heat dissipation area is not large, less effective, complex process. Although the condenser is a consumer needs to understand the purchase of indicators, but as the compressor, refrigeration evaporator, such as aluminum plate tube, silk tube evaporator and filter drier and other components, consumers do not need to be too concerned about which form of condenser. Because the next refrigerator for you to buy indicators in the freezing capacity, is the overall cooling effect of the refrigerator to a clear national standard data for you to show, we do not need to care about the refrigerator using which technology, only need to care about this refrigerator to bring the freezing capacity is how high can be.
Four, quality
Refrigerators are usually used for a long time, we are choosing a refrigerator with the intention of using for a long time, so it is very important to choose a good quality, durable refrigerator. Differences in manufacturing quality between brands have gradually disappeared with the development of the refrigerator industry. Therefore, design, technology and raw materials become the main reference for us to consider the quality of refrigerators. The design should be humanized and meet the needs of life. Manufacturers with a high technological base tend to have more guaranteed quality of refrigerators. In the selection of materials, pure steel pipe, imported coated steel plate and other high-quality components is the refrigeration system life of the finger
Five, reasonably low energy consumption
In the purchase of refrigerators there is another issue to consider is the future use of electricity will be generated in the process of use, which is not a small but easy to let a person ignore the spending. With consumers shopping more and more rational, the energy consumption of the refrigerator has attracted widespread attention, manufacturers have launched an energy-saving refrigerator. But it is not the lower the better, some manufacturers in order to achieve the purpose of energy saving and simply take the increase in insulation or the use of new technologies, but this energy saving is to increase the price of the price, while the performance will also be affected.
