How to identify the performance of refrigerated display refrigerator?

How to identify the performance of refrigerated display refrigerator?

Undoubtedly, the vast majority of consumers pay special attention to the performance of the product when purchasing other household appliances. So, how should consumers check the performance of the freezer? In fact, there are many methods, and one of the more common and simple methods is to check with electricity. The editor teaches you how to identify the performance of refrigerated display cabinets!


First, adjust the temperature controller knob of the refrigerated display cabinet to a certain position, and then connect to the power supply. It can be started once. After the refrigerated display cabinet has been running for a few minutes, you can touch the condenser of the refrigerated display cabinet with your hands. It means that the performance of the refrigerated display cabinet is better. If the refrigerated display cabinet has no cold feeling, it means that the performance of the freezer is poor. If the refrigeration is added too much, there will be frost on the air return pipe during the power-on process, which will not accumulate large power consumption, and the cooling effect will not be very good.


After the refrigerated display cabinet has been running for 20-30 minutes, check whether there is a thin and uniform layer of frost on the surface of the evaporator inside the refrigerated display cabinet. If there is, the refrigerated display cabinet has better refrigeration performance. Press the switch of the fan with your hand, and cold air is coming out of the air outlet at this time.


In addition, the noise of the refrigerated display cabinet is also one of the main performances to judge the performance of the freezer. The noise of the refrigerated display cabinet mainly comes from the resonance of the compressor with the pipeline and the cabinet when it is running. However, when buying a refrigerator in a store, due to the relatively high environmental noise, it is difficult to distinguish the noise of the refrigerated display cabinet, but the low fan rotating sound can be heard around. But if you touch the cabinet with your hand, you will feel a slight vibration, which is because most compressors have little noise.
