How does the Air Conditioner Compressor work through its internal mechanisms (such as piston or screw, etc.)?

Air Conditioner Compressor, that is, air conditioning compressor, works through its internal mechanism such as piston or screw to realize the compression and circulation of refrigerant. How the compressor works through these internal mechanisms is explained in detail below.
For a piston compressor, its interior mainly includes piston, cylinder, crankshaft and other mechanisms. The motor drives the crankshaft to rotate, and the crankshaft drives the piston to reciprocate in the cylinder. When the piston moves downward, the volume in the cylinder increases, forming a low-pressure environment, allowing refrigerant vapor to be inhaled; when the piston moves upward, the cylinder volume decreases, compressing the refrigerant vapor, causing its pressure and temperature to increase. In this way, the reciprocating motion of the piston realizes the suction, compression and discharge process of refrigerant.
The screw compressor works through the meshing motion between the main screw and the auxiliary screw (or the main screw and the inner wall of the housing). When the main screw rotates, the auxiliary screw or the groove on the inner wall of the housing sucks the refrigerant from the inlet and pushes it forward as the screw rotates. Through the continuous rotation of the screw, the refrigerant is compressed in the screw cavity, and the pressure and temperature gradually increase until the required compression state is reached. The compressed refrigerant is then discharged through the exhaust port and enters the condenser for cooling.
Whether it is a piston or a screw compressor, the core principle is to compress the refrigerant through the movement of the internal mechanism to increase its pressure and temperature. In this way, the compressor can promote the circulation of refrigerant in the refrigeration system to achieve the refrigeration effect. At the same time, in order to ensure the stable operation and efficient refrigeration of the compressor, it is also necessary to equip the corresponding cooling system, lubrication system and control system.
In summary, the Air Conditioner Compressor compresses the refrigerant through the movement of its internal mechanisms such as piston or screw, pushing it to circulate in the refrigeration system to achieve the cooling effect. The design and operating status of these internal mechanisms directly affect the performance and efficiency of the compressor. Therefore, the characteristics and requirements of its internal mechanisms need to be fully considered when selecting and using a compressor.
