CD 30 ÷ 5207.3 Principle of Digital Scroll CompressorScroll 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 noneed to worry about lubrication failures, which realizes the wide-range capacity adjustment ofcompressor. This can save the transformer cost and consumption, decrease the interference ofhigher harmonic wave upon power transmission system, enlarge the work condition range ofcompressor.Summuruzing: Widen capacity range from 10% to 100%; Stepless energy adjustment with higher SEER and lower energy consumption; The PWM solenoid valve can be used 40 million times on average, about 30 years; High reliability and compressing ratio by utilizing axial flexible sealing technology; Outstanding SEER approved by JIS and ARI; With the unique flexible technology, remarkably enhancing the abilities of anti-liquidpumping and anti-rubbing, which can prevent the compressor from liquid pumping in mostof cases; Free of electromagnetic disturbance; Free of additional oil recycling equipment, achieve longer pipeline and higher dropdifference design.8. Features• Easy assembling Each module has independent structure, protect function, refrigeration system, powersupply and control system. When some problems occur in one of unit (auxiliary unit),others can keep running normally. Unit can be assembled by variable modules (up to 8) according to different capacityrequirement and the capacity can reach to 480kW (8×60kW). Modules can be installed closely or within a certain distance according to differentspace requirement. Compact structure, easy maintenance.21
