Which refrigerator is better for cooling

Different cooling methods of refrigerators have different advantages, mainly depending on which cooling method is selected. The direct cooling refrigeration type is cheap, relatively energy-saving, and has good fresh-keeping and moisturizing properties, but the temperature is uneven, and it needs to be defrosted frequently.

Why is the refrigeration compressor always overheating protection?

Compressor overheating protection means to protect the compressor motor from being burned. When the motor temperature or the compressor's own temperature exceeds a certain value, some built-in or external protection devices are used to disconnect the compressor's working power supply to achieve protection The role of the compressor.
