The principle of centrifugal compressor structure Structure principle of centrifugal compressor <img src="{{media url="The_principle_of_centrifugal_compressor_structure.jpg"}}" alt="" /> Centrifugal compressor is composed of rotor, stator and bearing. The impeller and other parts are sleeved on the main shaft to form a rotor. The rotor is supported on the bearing and driven by the power machine to rotate at high speed.

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.
