Moisture is taken away, and drying speed is faster.
Frequency-changeable compressor includes that raising frequency stage, frequency keep stage, frequency reducing stage: after compressor start, compressor operation
Frequency gradually rises to the highest operating frequency (target setting frequency) from low frequency rather than directly transports with the highest operating frequency
Turn.Compressor frequency rises and also can divide multiple stage, rise to run after each frequency stage 0.5～3 minute steadily after again
Rising to another frequency stage, during rising, speed is 1Hz/s～1Hz/60s；(such as 28～40Hz/s；40～50Hz/s；
50～60Hz/s；), the most directly rise to maximum speed be in order to: prevent the oil within compressor at frequency i.e. rotating speed
After flying up, return to the oil mass of compressor less than the oil mass discharged from heat exchanger, cause lubricating bad, increase compressor
The abrasion of inner part.When preventing vaporizer from starting, cold-producing medium evaporates the most completely, makes liquid refrigerant enter compressor, dilution
Lubricating oil within compressor, causes lubricating bad.The raising frequency stage, compressor operating electric current I to be monitored, reflection condensation
The condenser surface temperature of temperature and the compressor exhaust temperature of reflection compressor internal temperature, if reaching the limit of requirement
Value, then frequency keeps, even if frequency does not rise to rotating speed of target, the most no longer rises.
