26. chilled beam work at site
In the IPB project Chilled Beams are being installed in second floor to sixth floor.
Chilled Beam Water in Temperature is 16° C and water out temperature is 20° C.
Room temperature maintained is 26 ±1 ° C.
Chilled Beams with Drain pan are used to drain out water droplets due to condensation during monsoon.
160 TR of air conditioning load of the Building is met through Chilled Beam system.

29. A geothermal heat exchange work at site
There are 180 vertical bores at the Depth of 80 meter all along the Building Premises. Minimum 3 meter distance is maintained between any two bores.
Each bore is lowered with HDPE pipe U-loop (32mm outer Dia.) and grouted with Bentonite Slurry.
Each U-Loop is connected to MS Header Pipe(100mm Dia.)which finally joins the Condenser Water Line in Plant Room.
Condenser hot water is sent at 100°F (37.8° C) & back at 900 F (32.2° C).
One U-Loop has 0.9 TR Heat Rejection capacity, so all together 160 TR of Heat rejection is obtained without using a cooling tower.
