refrigerant flow in Scroll Compressors
The internal operation of a scroll compressor contain basically two parts: a stationary scroll and an orbital scroll. The stationary scroll (Figure 1.1) is attached to the rear of the compressor by four bolts (Figure 1.2), while the orbiting scroll (Figure 1.3) is attached to the clutch via a crank shaft and continuously orbits inside the stationary scroll. (See Figure 1.4)
The orbital movement (shown in figure 1.4) shows refrigerant being compressed between the orbital and fixed scroll. The inlet opening draws in the gas. This gas is then compressed into the center of the scroll, where it is discharged. As the scroll orbits, and the opening becomes smaller, the pressure rises and is forced out the rear of the compressor.
