Radiant ceiling heat panels

·         A temperature-controlled surface that cools indoor temperatures by removing sensible heat 
·          Half of heat transfer occurs through thermal radiation.
·         provide radiant cooling or heating to the occupied space
·         air-and-water systems that separate the task of ventilation and thermal space conditioning
·         primary air distribution to fulfil the ventilation requirements
·         secondary water distribution system to thermally condition the space.



Benefits of  the Radiant Ceiling Heat Systems

  • Quiet, safe and clean
  • Superior heating comfort -gentle even temperature from floor to ceiling
  • Aesthetically pleasing design - system is completely concealed
  • Room temperature can be verified from anywhere in the building
  • Rooms can be programmed so that you minimize operating costs while maximizing comforthttp://cdncache-a.akamaihd.net/items/it/img/arrow-10x10.pngaccording to your lifestyle
  • Control system allows for customization of heated areas
  • 100% energy efficient
  • Maintenance free and easy to install
  • Excellent for spot cooling or heating, supplementary cooling or heating, or integrated with active chilled beam diffusers to provide a total comfort solution
·         Due to physical properties of water, the radiant cooling systems can remove a given amount of thermal energy using less than 5% of the fan energy that would otherwise be necessary
·         Duct work need only about 20% of the space requirements of conventional HVAC systems, reducing cost for hydronics cooling


Difference between cooled ceilings and air conditioning

·         Heat transport mechanism
·         Air conditioning uses convection only using air distribution through duct work

·         Radiant cooling uses a combination of radiation and convection.
