A scroll compressor is a device that produces compressed air by rotating a spiral-shaped rotating plate (scroll).
The features of a scroll compressor are as follows:
An example of an application for scroll compressors is home air conditioner.
Compression makes the air hot. The hot air is cooled by a fan in the outdoor unit. As it cools, it turns into liquid water. The pressure then drops, and the water vaporizes.
The vaporized water then removes heat from its surroundings due to the heat of vaporization. The air becomes cold because of the heat loss. By replacing the cooled air with the indoor air in a device, a cool breeze enters the room. This is how cooling works, and the opposite cycle is used for heating.
The moving part of scroll compressors consists of two scrolls: the first is a fixed scroll; the second is a swirling scroll.
When gas enters through the inlet port, the swirling scroll rotates. The rotation compresses the air, which accumulates in the gap between the stationary scroll and the swirling scroll. When a certain amount of air is accumulated, compressed air is pushed out from the discharge port at the center. Once the compressed air is pushed out, the swirling scroll returns to its initial position. This cycle is repeated to deliver compressed air continuously.
As the compressor continues to be used, water will accumulate due to condensation. If the accumulated water is left unattended, it will lead to rust, and the air tank will no longer serve as a tank. Further rusting can lead to the failure of the compressor itself. Therefore, regular cleaning is important.
The temperature of the surrounding environment also has an effect on the compressor. Placing the compressor under extremely low or high temperatures can shorten its service life, so proper temperature control is necessary.
