Smart Ceiling with Hybrid Solution

Conditions

Low outdoor temperature part of the year or at night for night cooling.
Room with heating load from persons, lighting, IT (machinery), heat transmission through the building and solar irradiance through the windows.

Solution

Smart Ceiling controlled ventilation, cooling and heating supplied with Hybrid for direct cool-ing and using low outside temperature. The damper for the inlet air is closing (or the fan can be halted), when the Hybrid damper opens. Control of the air volume (VAV-Damper and Hybrid Damper) according to the temperature and/or the CO2 load.

Components

• Air inlet from the main ventilation system over the ceiling (no ducts)
• VAV-Damper
• Hybrid inlet with damper
• Smart Ceiling (Metal Ceiling)
• Inlet diffusers mounted in the ceiling
• Exhaust diffusers can be placed in the ceiling, in the wall or where it is best for the design of the room

Benefits
