Chilled Ceilings

Chilled Ceilings principally cool through the process of Radiant Exchange - a heat transfer between surfaces of differing temperatures. In a room served by a Chilled Ceiling, the surface temperature of the ceiling would normally be in the range of 15°C to 18°C. This would provide a very pleasant radiant cooling effect to people in that room with minimal air movement. Typically, up to 60% of Chilled Ceiling cooling output is achieved through this Radiant Exchange mechanism.

Chilled Beams

Chilled Beams achieve their cooling effect by convection, using finned elements through which water is passed at around 15°C to 18°C. Passive beams work via natural convection, while active beams offer an increased cooling capacity by using a primary air supply to cause induced convection over the elements. The primary air is then supplied to the room through diffusers built into the beam. Chilled Beams can be installed flush with most false ceilings or fully exposed in aesthetic casings.

Fields of Application

Chilled Ceilings and Chilled Beams have been successfully used for comfort conditioning in a wide range of applications throughout the UK and mainland Europe. These include offices, banks, dealing rooms, retail outlets, public buildings and industrial processing plants. They are particularly suitable where high comfort levels are required with minimal noise or air movement.

Comfort with Care

Because Chilled Ceilings and Chilled Beams are energy efficient and need only minimal mechanical refrigeration, they are much more environmentally friendly than other building cooling systems.

Benefits compared with other systems:

• more modest chilled water temperature requirements
• enhanced scope for free cooling
• consume less electricity
• lower running and maintenance costs
• require less installation space

Providing

• Care for the environment
• Comfort for All
