It is understood that the air-cooled precision air-conditioning system equipped with EC fans can greatly improve the PUE value of the data center. The base station precision air conditioner of INVT Network Power adopts Fans-tech or Ziehl-Abegg's EC fan, which is designed with large air volume, small enthalpy difference, and a high sensible heat ratio. Compared with traditional fans, it is more energy-efficient and can meet the temperature control requirements of server rooms, so as to bring a better user experience to the Dalian Border Control Station.
