RADIANT COOLING TECHNOLOGY
Implementation of Radiant Cooling Technology & integration with Central Command Center at Infosys EC 53 Building, Bangalore
INFOSYS EC 53 Building, Bangalore
Software Development Park: 2.7 Lacs Sq.ft temperature conrolled area
Dual operating Temperatures: Elevated and Lower

– Low Temperature latent Cooling Capacity: 200 TR
OBJECTIVE
-
Optimum Energy Use
-
Improved Comfort
-
Operational Efficiency
-
Lower Breakdown
Radiant Cooling system works on radiation & convection heat transfer, using Radiation as technology and Water (3400 times more cooling than air) as medium for cooling. Radiation is the fastest mode of heat transfer (^4 faster than conduction & convection)
RADIENT COOLING
Radiant system works on radiation & convection heat transfer.
Between conduction, convection and radiation, radiation is the fastest mode of heat transfer.
It is ^4 faster than conduction and convection.
Use Radiation as technology and Water (3400 times more cooling than air) as medium, as compared to Convection and air as medium for cooling.

THE RESEARCH
Mock up panel was built in our factory. A mock up room was created along with mini chiller, Tank and circulation system. Space heaters for adding load in the conditioned space
Thermal Imager was used to check uniformity of cooling across the entire surface area of the panel and balance the same. We recorded a absorption of 8 watt/Sqft on the panel which was ideal as per our calculation.
