DC Variable Frequency Multi-Split Central Air Conditioning Unit

DC Variable Frequency Multi-Split Central Air Conditioning Unit

SINO KING DC Variable Frequency Multi-Split Unit adopts DC inverter vapor injection compressors combined with intelligent frequency drives and high-efficiency oil separators, creating a central air conditioning unit with superior power output, high efficiency, and stable operation.
Product Features
  • Wide capacity coverage range

      Wide capacity coverage range

      Single module 10-34HP, maximum combined capacity up to 102HP (≤3 units), meeting load capacity requirements ranging from 25KW to 285KW.
  • Anti-liquid return control system

      Anti-liquid return control system

      The multi-point sensor monitoring and precise superheat control functions ensure that the refrigerant returning to the compressor remains in gaseous state. Besides, the high-efficiency gas-liquid separator effectively separates liquid refrigerant from returned gas and prevents liquid from being suctioned in by the compressor.
  • DC Variable Frequency Enhanced Vapor Injection Compressor

      DC Variable Frequency Enhanced Vapor Injection Compressor

      The DC variable frequency compressor has a high-rigidity casing and employs the anti-overcompression and anti-liquid slugging technology. It directly suctions air into the compression chamber, achieving high volumetric efficiency. Additionally, the unique enhanced vapor injection technology of the compressor, paired with the advanced secondary subcooling technology of the system, increases refrigerant circulation at low temperatures, significantly improving the low-temperature heating capacity.
  • High-efficiency subcooling technology

      High-efficiency subcooling technology

      The unit adopts an optimized outdoor heat exchanger circuit design to achieve primary subcooling, combined with a high-efficiency stainless steel plate heat exchanger for secondary subcooling. After deep subcooling, the subcooling degree can reach up to 30°C, significantly improving the unit efficiency while effectively preventing refrigerant flash evaporation in long pipelines, reducing heating/cooling capacity attenuation, and enhancing practical performance of the unit.
  • Wide-range stepless frequency modulation

      Wide-range stepless frequency modulation

      The advanced DC variable frequency control (VFC) technology enables continuous stepless adjustment of compressor speed and intelligently adjusts system output under varying loads to truly achieve on-demand capacity regulation. The wide capacity adjustment range and 45Hz~390Hz broad frequency range are sufficient to meet extreme load variation demands.
  • Intelligent defrosting technology

      Intelligent defrosting technology

      The "auto-sensing" intelligent defrosting technology automatically adjusts defrost conditions based on real-time outdoor unit temperature and pressure parameters, ensuring accurate defrost settings for optimal energy efficiency. It implements a precise control of "more frost more work, no frost no work," maximizing the normal heating operation time and effectively avoiding heating loss during defrost mode.
