DC Variable Frequency Air-Cooled Direct Expansion Packaged Air Conditioning Unit

DC Variable Frequency Air-Cooled Direct Expansion Packaged Air Conditioning Unit

SINO KING DC Variable Frequency Air-Cooled Direct Expansion Packaged Air Conditioning Unit is a new generation of high-efficiency product developed by SINO KING with advanced design concepts and technology. Based on packaged purification air conditioners, the unit offers higher precision in temperature and humidity control. The rapid heating/cooling and continuous operation under low loads make it an energy-saving, wider-temperature-range, and quieter high-end product.
Product Features
  • More efficient and quieter operation

      More efficient and quieter operation

      Employs AMCA certified double-intake multi-wing high-efficiency centrifugal fans and specialized anti-vibration measures for stable performance and more efficient, quieter operation.
  • Uses AMCA certified double-intake multi-wing high-efficiency centrifugal fans

      Uses AMCA certified double-intake multi-wing high-efficiency centrifugal fans

      The indoor unit adopts AMCA certified double-intake multi-wing high-efficiency centrifugal fans, and is equipped with anti-vibration measures for stable performance and more efficient, quieter operation. Customers can also opt for variable frequency motors based on actual variable air volume needs; if so, the noise would be lower when the air volume is reduced.
  • Meeting extreme load demands

      Meeting extreme load demands

      Intelligently adjusts linear output under varying loads based on actual air conditioning needs for energy savings; The wide frequency range of 15Hz–260Hz can meet extreme load demands.
  • Compressor automatic oil return + system intelligent oil return

      Compressor automatic oil return + system intelligent oil return

      Adopts the compressor automatic oil return + system intelligent oil return technology to achieve dynamic oil balance of parallel compressors, balance the oil volume of each compressor, ensure the system oil volume is within an appropriate range, and ensure the efficient operation of the unit.
  • Improves heating/cooling capacity attenuation issues

      Improves heating/cooling capacity attenuation issues

      Optimized outdoor heat exchanger circuit design, combined with high-efficiency stainless steel plate heat exchangers, enables secondary subcooling. With subcooling reaching up to 30°C, it significantly improves the unit efficiency, effectively prevents refrigerant flash evaporation in long pipelines, and reduces heating/cooling capacity attenuation.
Suitable for
Especially suitable for places with higher requirements for temperature and humidity, such as operating rooms, electronic factories, pharmaceutical factories, data centers, etc.
