Scroll compressors, twin-rotor compressors, and oscillating compressors each have their own features and benefits, and the choice of which compressor is better depends on the specific application and needs.
Scroll compressors have the characteristics of high efficiency, low noise, low vibration and low wear, so they are widely used in some high-end air conditioning and refrigeration equipment. Its continuous unidirectional suction, compression, and exhaust process results in less gas leakage and high volumetric efficiency. However, scroll compressors have high requirements for machining accuracy and assembly accuracy, and the manufacturing cost is high.
Dual-rotor compressors have the advantages of simple structure, small size, light weight, high reliability and long life, so they are widely used in some household appliances and automotive air conditioners. Its two rotors mesh with each other, resulting in a smoother compression process and less vibration and noise. However, dual-rotor compressors are relatively inefficient and can increase noise and vibration during high-load operation.
Oscillating compressors have the advantages of simple structure, small size, light weight, high efficiency and low noise, so they are widely used in some small refrigeration equipment and air conditioners. Its oscillating mechanism causes the piston to reciprocate in the cylinder, thus completing the compression process. However, oscillating compressors have high requirements for wear resistance and sealing, and also have certain requirements for the quality of lubricating oil.
In summary, each of the three compressors has its own advantages and disadvantages, and choosing which one is better needs to be evaluated according to the specific application scenario and needs. For example, in high-end air conditioning and refrigeration equipment, scroll compressors may be more suitable; In household appliances and automotive air conditioners, dual-rotor compressors may be more suitable; For small refrigeration equipment and air conditioners, oscillating compressors can be a good choice.
