1 The Radiant System For CEILINGS AND WALLS energy hydraulic solution Eco-enerdigm was built on the technology of Samyang System Group that was founded in Since 2003, Eco-enerdigm has been testing and researching radiant cooling and heating system and has adopted the European radiant cooling system that is eco-friendly. In year 2007, an Italian company, RDZ (the specialty company of radiant system), has offered their 40 years of knowledge and experience in radiant cooling system. Now Eco-enerdigm can offer both the best technology and local knowledge from the two companies above and provide every need from system designs, installations to after services.

2 U-Radiant : Radiant Introduction U-Radiant system is the newest technology that is proven to provide highest comfort level for human body and to be ecological. Radiant cooling system controls the temperature and humidity evenly without force of air thus keeps the comfort level of the indoor at its best condition. It is also designed to control humidity for 24 hours. It also opened up possibilities of interior design because the whole system is hidden behind walls, ceiling panels or under floor. Experience the new coolness! U-Radiant : Advantages of Radiant System Conditions for the Ideal Indoor air quality : Energy, comfort, Eco-friendly U-Radiant will reduce energy cost comparable to conventional AC system ENERGY High efficiency with heat transfer Cost reduction for maintenance Minimize the loss of heat No need to use forced convection for heat distribution U-Radiant can provide the best indoor condition adjusting both the temperature and the humidity gradually and sensibly. Healthier environment with less noise and micro-particles in the air Automatically controls the ventilation, temperature and humidity for 24 hours Prevents cold draft and discomfort due to convection such as AC system COMFORT U-Radiant is high-technology system using chilled water that is Eco-friendly ECO-FRIENDLY Heat source changes to chilled water which has higher efficiency for heat transfer Less energy needed to run the system Less CO 2 exhausted Produces less air pollution and safer for ozone layer U-Radiant is hidden in ceiling, wall, or floor No space for AC needed and frees option for interior design Floor to floor height reduction Smaller mechanical room required DESIGN 2 3

3 Invisible Comfort at all times. U-Radiant system is a climatic control system that can be installed in ceilings, walls and floors. This innovation is versatile and particularly ideal where the existing climatic control system is unsuitable or space is limited. Relatively low heat inertia, and high efficiency makes the system suitable for any habitats, renovated and new buildings. U-Radiant allows more space to be utilized by hiding the combined system in ceilings and walls. 4 5

4 U-Radiant : System Diagram Components for Radiant System Heat Source : Chiller, Geothermal, District heating or cooling Manifold : Main manifold, Sub-distributor Radiant panel : for ceiling, wall, and floor : Metal panel, Plasterboard panel Components for Air exchange & (De)humidification (De)humidifier : Adjust the humidity in the air and prevent any condensation or increase humidity. Heat Regenerator : Partial or total renewal of the air in a room and exchange exhaust air with supply air. Components for Intelligent Thermoregulation System Central Unit, sensors, Probe for outside temperature Constant control of dew point on the radiant surfaces Automatic activation of the heat generator or the heat source Activation of the circulation pump and various areas Activation of the (de)humidification system according to the requirements User interface Radiant System + Air exchange & (De)humidification system + Intelligent Thermoregulation System 6 7

5 U-Radiant : Plasterboard panel This panel is adaptable to be installed in ceilings and walls with 40 mm thickness and density of 30 kg/m 3. The panel with 27 mm is designed and produced to minimize the heat lost to the structure near it. Within the panel, a U-shaped hole is preformed so 6 mm tube can easily be laid. The panels and tubes are then covered with a special coat that increases the efficiency of heat transfer. Dimensions.
