FY 2017 Innovation with No Investment Project
Hub Room AC Switched off
Pre Scenario
20 Hub rooms
24x7 Air conditioning provided
Switches designed to operate in temperature upto 42°C
Switches not required to be
accessed after office hours
Post Implementation
Switching off of hub room AC s
during night & holidays
Temperature does not exceeds beyond 26 °C due to residual
cooling
No impact what so ever on the IT

Set points adjusted as per
seasonal variation

Innovative Project Auto Tube Cleaning System
Balls injected through condenser inlet, these balls descale the tubes
Impurities collected are discarded through condenser outlet
Innovative Project Auto Tube Cleaning System
Pre Project Scenario
With usage of water cooled
chillers there is fouling inside the
condenser tubes
Resulting in higher kW/ TR
Manual cleaning is difficult &
requires shut down of approx. 24
hours
Post implementation
ATCS is installed as a retrofit on
old chiller & it’s an integral part of
the chiller
Chiller efficiency is maintained
Investment
Projects
Electronically Commutated (EC) motors for AHUs
Features:-
• Low losses & hence 40% less input power to deliver same CFM
• Permits part load operations even at 10%
• Less noise & Elimination of VFD
• Smooth speed control

Tri-rotor water cooled chiller
Features:-
• Full & part load efficiencies are superior to twin rotor screw
technology
• Vastly reduces bearing loads
• Less moving parts – high reliability
• Very low inrush current
• Highly reliable operations even in worst operating conditions
• Specially designed environment friendly R-134a refrigerant
• Capacity control by VFD

Installed capacity reduced from
1820 TR to 1670 TR
New Chiller kW/TR 0.69
ROI 2.9 years
