New NF series DC fan–cooled condensing unit adopts the world famous brand-Danfoss, Copeland, Tecumseh compressor.-Danfoss Refrigeration components, ABB electrical equipment- Optimization design system- Equipped with condensing temperature controller make the units works always at the best conditions.- Panasonic energy-efficient direct current fan motor- High COP- Compliant with the latest EU standard-Refrigeration capacity: 1.5kw-15kw-Refrigerant : R404a R134a

The energy consumption and performance of DC Fan-cold condensing unit
  • Designed based on the requirement of Europe
    - Applicable refrigerant:R404A,R134A,R22
    - Set outlet temperature of condenser :35℃,(R404a, condensing pressure/gage pressure 15kg)
    - Max rpm: 680rpm. Motor input energy consumption :85w
    - Min rpm:100rpm, Motor input energy consumption:2.5w
    - Auto-adjust temperature and rpm
     
  • Fan energy consumption
    - The rpm of the fan is 190rmp when the ambient temperature below 17℃. motor input energy consumption is 5w
    - When the ambient temperature exceed 25℃,the rpm of the fan is full speed 680rpm. Motor input energy consumption is 85w
     
  • Condensing pressure(R404a, measured value)
    - When the ambient temperature below 25℃,gage pressure is 15kg. Condensing temperature is 35℃
    - When the ambient temperature exceed 25℃, the condensing temperature will rise
    - When the ambient temperature is 40℃,the gage pressure is 21kg. Condensing temperature is 48℃
    - When the ambient temperature is 43℃,the gage pressure is 22.5kg.Condensing temperature is 51℃
     
  • Condensing pressure(R134a calculated value)
    - When the ambient temperature below 25℃,gage pressure is 8kg.. Condensing temperature is 35℃
    - When the ambient temperature exceed 25℃, the condensing temperature will rise
    - When the ambient temperature is 40℃,the gage pressure is 10.05kg. Condensing temperature is 45℃
    - When the ambient temperature is 43℃,the gage pressure is 12.5kg, Condensing temperature is 51℃
     
  • When at the max rpm, noise will be lower obviously than outer-rotor fan. And can auto-adjust the temperature and rpm.
