How to distinguish the quality of the freezer？
When we buy a refrigerator, we need to choose the right refrigerator through various conditions. But a lot of people do not know how to distinguish whether the quality of the refrigerator is good or bad, whether it is worth buying. Here are some ways to tell you apart:
The core of the refrigerator is its compressor, a refrigerator needs refrigeration to rely on the compressor operation. So the importance of the compressor can be imagined, so if the compressor quality is good, the quality of the refrigerator is completely different. We can drop a few drops of water on the evaporator to see if it turns to ice in seconds, and if so, then that means the compressor is of good quality. The Green&Health cooling commercial freezers adopts famous brand and high efficiency compressor, with features of fast refrigeration, low noise, safe and stable.
The foaming layer of the freezer. It is the insulation layer of the refrigerator. The foaming layer with good quality can preserve the cold air inside the refrigerator. Otherwise, it is easy to leak the air conditioning, and you can not refrigerate the food well. To distinguish whether the foam layer is good or bad, you need to use the hand to try, a good foam-layer pinch up is very real, the weight is also very heavy, and the preservation effect, energy-saving effect is better. Green&Health refrigerator is the whole polyurethane foaming, not only high density, but also safe, power saving and beautiful.
The evaporator of the refrigerator is a very important part. The evaporator determines the refrigeration speed and preservation quality of the freezer. ① Evaporator design: the design of the evaporator needs to give the evaporation temperature, overheat, and the liquid temperature before the expansion valve. All-copper tube evaporator has fast refrigeration and strong preservation effect.② Refrigeration capacity: the refrigeration capacity directly determines the effective evaporation area of the evaporator, namely, the number of fins, the size and the length of the pipe. The more reasonable the evaporator design, the better the refrigeration performance.
How to judge whether the refrigerator is operating normally？
Carefully observe the working situation of each component of the refrigerator, focus on the refrigeration system, electrical system, fan system these three parts, to judge whether they work normally.
1. Refrigeration system: observe whether there are cracks, damage, frost and dew in the refrigeration system. There is no collision or friction between refrigeration pipelines, pipelines and shell, especially at the welding place of refrigerant pipeline, there is no leakage at the joint connection. Any leakage there will be oil (there is a certain amount of refrigeration oil), can use clean soft cloth or soft paper to wipe the pipe welding and joint connection, observe whether there is oil, to judge whether there is leakage.
2. Electrical system: observe whether the fuse of the electrical system is fused, whether the insulation of the electrical wire is intact and undamaged, whether the circuit board is broken, whether the connection is loose, etc. Especially whether the electrical connection is in good contact, wiring screws, plugs are easy to loose resulting in poor contact.
3. Ventilation system: observe whether the air filter screen, heat exchanger coil and fins accumulate excessive dust. Air inlet and air outlet are unblocked. Whether the fan and fan blades operate normally. etc.
