What Is a Scroll Compressor?

Scroll compressor is a kind of positive displacement compressor. The compression part is composed of moving scroll and static scroll. Includes many structural features that allow for a shunt flow of gas through the compressor housing to reduce entrained oil.

Scroll compressor

Scroll compressor is a kind of positive displacement compressor. The compression part is composed of moving scroll and static scroll. Includes many structural features that allow for a shunt flow of gas through the compressor housing to reduce entrained oil.

After entering the housing, certain gases flow upward to reduce the amount of gas flowing downward toward the oil. To achieve this, the motor of the compressor may be surrounded by a sleeve having upper and lower holes for directing airflow to the turns of the upper and lower stator ends of the motor. In some embodiments, the suction inlet is importantly positioned relative to the two gas passages between the stator and the motor housing. The location of the inlet allows a channel to receive the incoming gas and divide the flow into two opposite directions, i.e., upward and downward. The other channels only carry gas upwards. In addition, suction baffles, diffusers, streamlined weights, and suction pipe oil catchers can also help separate gas and oil or minimize entrained oil.

Features

Simple structure, small size and light weight

1. There is no reciprocating mechanism, so the structure is simple, small in size, light in weight, few parts (especially fewer wearing parts), and high reliability;

2. Small torque change, high balance, small vibration, and stable operation, which is easy to operate and easy to realize automation;

3. It has high efficiency in the range of its cooling capacity;

4. Low noise.

1. The surface of its moving parts is mostly curved. The processing and inspection of these curved surfaces are more complicated, and some require special equipment, so the manufacturing cost is higher.

2. Between the moving parts or between the moving parts and the fixed parts, the seal is often maintained by maintaining a certain movement gap. Gas passing through the gap is bound to cause leakage, which limits the

The turbo compressor was first born in 1905 and was invented by French engineer Leon Creux. Due to the limitations of processing technology? Mass production began only in the early 1980s. 1973 United States ADL. The company presented a research report on scroll nitrogen compressors, and proved that scroll compressors have advantages unmatched by other compressors. As a result, large-scale engineering development and research of scroll compressors has embarked on a rapid development path.

The core component of the air conditioner is the compressor. A compressor can account for 30% to 40% of the cost of the entire air conditioner. The quality of the refrigeration system is also the most closely related to the compressor. It is important to understand the compressors used. A good compressor will perform better in terms of service life, noise and energy efficiency.
