Energy Saving Fresh Air Intake

  • ENERGY SAVING FRESH AIR INTAKE
  • In a building where there are many occupants, carbon dioxide content will grow higher and higher since people take in oxygen and expel carbon dioxide. The resulting decrease in oxygen and increase in carbon dioxide may cause some occupantsdizziness due to low oxygen. SAIJO DENKI has provided an intelligent solution to indoor air quality by using a maximized energy saving method to take fresh air into the building.
    The Energy Saving Fresh Air Intake system has been developed to introduce fresh oxygenated air into the building in aenergy efficient way by making use of the principle of exchanging the high-temperature air coming into the building with the lower-temperature air coming out of the building. This results in reduced temperature of the incoming air, allowing the air conditioning system to work less hard and be able to save more energy

  • General System (Direct Fresh Air Intake)
  • Outside the building

  • Reduction of Air Temperature before Entering the Building
  • The energy-saving system helps reducing the temperature of oxygenated outdoor air before being drawn into the building, thus, allowing the air conditioner to work less hard.
    If fresh air is directly taken into the building, the air conditioner will have to work hard since it needs to reduce the air temperature down from 40 C to 25 C to be equal to room temperature and make the room occupants feel comfortable. This means that the air conditioner has to reduce the air temperature by 15 C

  • Maximized Energy Saving and Noise Reduction with DC Motor


  • Bring Fresh Air into building with Energy Saving Technology
