How to choose a freezer
1. Make sure that a high-efficiency compressor is used. Like the human heart, it is a very important compressor. It is also the main energy-consuming component of the refrigerator. Using a high-efficiency compressor is a simple and effective way to save energy in the refrigerator.
2. Whether to adopt new type of energy saving. Different working media of refrigerators require different power consumption to achieve the same cooling capacity. This is directly related to the cooling effect of the freezer.
3, to achieve a high energy efficiency ratio. The energy efficiency ratio is the ratio of the actual cooling capacity to the actual input power during the freezer cooling operation under rated and specific conditions. The higher the energy efficiency ratio of the freezer, the more energy can be saved with the same cooling capacity.
Finally, pay attention to the protective measures of the freezer. With the above-mentioned energy-saving measures, after the refrigerator starts stable operation, power consumption is mainly used to overcome the temperature rise in the refrigerator to maintain the required low temperature. Therefore, energy-saving refrigerators should have relatively complete refrigerator protection measures, such as appropriate thickening of thermal insulation foam layers, improvement of foam materials and processes, and improvement of door sealing structures to reduce external heat transfer.
Second, the advantages of refrigerator components
If you can't see the advantages and disadvantages on the surface when you observe the refrigerator, you need to look at the interior of the refrigerator. How to judge the interior and exterior of the refrigerator?
1. Specific foam layer
The bubble layer is the heat insulation layer of the freezer. Its quality is directly related to the heat insulation effect of the freezer. The more practical the foam, the more practical the foam, the stronger the weight, the better the preservation effect and energy saving effect.
2. Dedicated evaporator
The quality of the evaporator determines the speed and preservation quality of the freezer.
3. Compressor comparison
The compressor is the core of the refrigerator. A good compressor can drop a few drops of water from the corner evaporator, and the water will turn into ice in a few seconds.
