2.7.1. Removing Transportation Fixing Plate of Compressor
Damping cushions are added to the base of compressor to reduce the vibration and noise during operation.
However, such method cannot best resist the vibration while transporting the unit and may result in loosening
connections and wearing of certain parts. Hence to ensure the rigidity of the compressor during transportation,
three L-shaped xing plates are added to the compressor bases.
