      The principle of central air conditioning refrigeration

      The principle of central air conditioning refrigeration The liquid Freon enters the evaporator through the capillary. The space suddenly increases and the pressure decreases. The liquid Freon will vaporize and absorb a lot of heat. The evaporator will become cold. The indoor unit fan will remove the indoor air from the evaporator. Blow through, so the cold air blows out from the indoor unit. Let's take a look at the cooling principle of the central air conditioner with the editor for your reference<img src="{{media url=&quot;magefan_blog/The_principle_of_central_air_conditioning_refrigeration.jpg&quot;}}" alt="" />

      Scroll compressor structure diagram <img src="{{media url=&quot;Scroll_compressor_structure_diagram_Scroll_compressor_advantages_and_disadvantages.jpg&quot;}}" 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=&quot;Scroll_compressor_structure_diagram_Scroll_compressor_advantages_and_disadvantages2.jpg&quot;}}" alt="" />
