2.2.12 Installation of radiant ceiling cooling

2.2.12 Installation of radiant ceiling cooling Description Radiant ceiling cooling systems, also known as “chilled beam” systems, incorporate pipes in the ceilings through which chilled water flows. The pipes lie close to the ceiling surfaces or in panels, and they cool the room via natural convection and radiation heat transfer. [...]

2.2.10 Installation of ground-air heat exchangers

2.2.10 Installation of ground-air heat exchangers Description Also known as earth tube, this system takes air from the exterior to introduce to the ventilation system or directly in interior spaces, after the air passes through pipes installed underground. Ventilation air is simply drawn through underground pipes at 1.5m deep which pre-heats the [...]
