Is the scroll air compressor okay?

Scroll air compressor shows good performance in many aspects. The following is a detailed analysis of its advantages:

efficiency: Scroll compressor has no suction and exhaust valves, which reduces airflow loss and improves efficiency. It leaks less gas, making it most efficient in domestic compressors. At the same time, its compression process is continuous, and the torque variation is small, which also helps to improve efficiency.

Small size and light weight: The scroll compressor has a compact structure. When the capacity is the same, its main components only account for 1/10 of the reciprocating compressor, the volume is reduced by about 40%, and the weight is reduced by about 15%. This makes it particularly suitable for applications where space is limited or where lightweight equipment is required.

Low vibration and low noise: Since the suction, compression, and exhaust processes of the scroll compressor are carried out continuously at the same time, the pressure rises slowly, so the torque change amplitude is small and the vibration is small. This makes it run smoothly, low noise, and has the reputation of "ultra-static compressor. At any frequency, the vibration and noise of the scroll compressor are lower than those of the piston compressor and the rolling rotor compressor.

High reliability: The axial and radial flexible mechanism of the scroll compressor improves the sealing effect, and can effectively reduce friction and wear, so that it can have higher reliability and sealing performance at high speed. In addition, the design without suction and exhaust valves also increases the reliability of its operation.

Good thermal performance and regulation performance: The scroll compressor performs particularly well in the heat pump air conditioning system, and has the characteristics of high heating performance, good stability and high safety. At the same time, it can achieve large displacement, and the operation is simple, the torque change is weak, and it is easy to realize automatic control.

However, scroll air compressors also have some disadvantages:

the manufacturing cost is high: because the surfaces of the moving parts of the scroll compressor are mostly curved, the processing and inspection of these curved surfaces are complicated, so the manufacturing cost is high.

High compression ratio limit: scroll compressor is difficult to achieve a large compression ratio, most of which are more suitable for use in air conditioning conditions. Increasing the number of turns of the scroll gear will cause the increase of the size of the whole machine and the aggravation of mechanical wear.

In summary, scroll air compressors have significant advantages in terms of efficiency, volume, weight, vibration and noise, and are suitable for a variety of applications. However, the manufacturing cost thereof is high and there are limitations in a high compression ratio. When choosing whether to use a scroll air compressor, you need to consider these factors and specific application requirements.
