8.3 Principle of Digital Scroll Compressor
Scroll system controls refrigerant output by the ratio of loading and unloading time of compressor,
and adjustment of loading time could be “stepless”. Furthermore, no need to change speed, and no
need to worry about lubrication failures, which realizes the wide-range capacity adjustment of
compressor. This can save the transformer cost and consumption, decrease the interference of
higher harmonic wave upon power transmission system, enlarge the work condition range of
compressor.
