Scroll compressor structure diagram <img src="{{media url="Scroll_compressor_structure_diagram_Scroll_compressor_advantages_and_disadvantages.jpg"}}" alt="" /> Scroll compressor is a positive displacement compression compressor, the compression component is composed of moving scroll and static scroll. Its working principle is to use the relative orbital motion of the movable and static scrolls to form a continuous change in the enclosed volume, so as to achieve the purpose of compressing gas. Mainly used in air conditioning, refrigeration, general gas compression, and used in automobile engine supercharger and vacuum pump, etc., it can replace traditional medium and small reciprocating compressors in a large range. <img src="{{media url="Scroll_compressor_structure_diagram_Scroll_compressor_advantages_and_disadvantages2.jpg"}}" alt="" />

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.
