Trane Scroll Compressor

— Maximum Efficiency with Enhanced Reliability

General

The scroll compressor has two scrolls. The top scroll is fixed and the bottom scroll orbits. Each scroll has walls in a spiral shape that intermesh.

Inlet-First Orbit

As the bottom scroll orbits, two refrigerant gas pockets are formed and enclosed.

Compression-Second Orbit

The refrigerant gas is compressed as the volume is reduced closer to the center of the scroll.

Discharge-Third Orbit

The gas is compressed further and discharged through a small port in the center of the fixed scroll.

Scroll Principal Components

This is a cutaway view of a hermetic, scroll compressor, showing the relative positions of the principal components. Shown is a Trane 10-ton, 3600 rpm, 60 Hz [3000 rpm, 50 Hz] scroll compressor as an example.

The principle of operation of this example compressor is as follows: The suction gas is drawn into the compressor at A. The gas then passes through the gap between the rotor and stator, B, cooling the motor, before it enters the compressor housing, C. Here, the velocity of the gas is reduced, causing a separation of the entrained oil from the gas stream. The gas then enters the intake chamber, D, that encircles the scrolls.

Finally, the suction gas is drawn into the scroll assembly where it is compressed and discharged into the dome of the compressor. The dome of this example compressor acts as a hot gas muffler which dampens the pulsations before the gas enters the discharge line, E.
