3. SAFETY PRECAUTIONS

4. SYSTEM COMPONENTS AND FUNCTIONS

This section describes the various air conditioning components, their purpose and operation. This

section is only a guide and does not consider all components that could be found on an air conditioner in

the field.

Generally, liquid refrigerant is suspected if valve damage occurs. Some compressors can tolerate the

gas gives it the name of “low-side” shell compressor

The scroll compressor used a helix (similar in shape to a snail shell)

within a similar stationary helix, the moving helix rotates so that the space between the two constantly

decreases as the gas moves toward the center of the Scrolls. The returning refrigerant gas first cools the

motor, then flows into the suction intake of the compressor scroll. The discharge gas leaves from the

center of the helix and exits the compressor. The lower part of the shell should be cool to the touch.
