1. 3min intelligent defrosting technology:
Ultra-low temperature full DC stepless inverter heating&cooling heat pump uses self-developed patented intelligent defrosting technology. If the frost layer coverage is more than 85%, it will switch into defrosting mode, ensuring the machine frost-free.
2.Ultra-low temperature full DC stepless inverter heating&cooling heat pump, the compressor of which uses EVI technology. 20% increase in amount of refrigerant flow, on the one hand, makes the operating
temperature range more wider as from - 30 ℃ to 50 ℃, and on the other hand, realizes two-stage compression function, which solving the problem of poor heating effect at ultra-low temperature, such as at -30℃.
3. 33dB low frequency silent cruise technology: ultra-silence
Ultra-low temperature full DC stepless inverter heating&cooling heat pump uses the self-developed 1 Hz DC stepless frequency modulation technology, and realize real-time precision control of various running parameters. When reaching the set temperature, the units automatically switch into low frequency cruise mode, and the volume is only 33 dB(in door), just as the sound of opening books in the library, which supplies you the most comfortable and quiet environment.
