TRIL Info park is part of Ramanujam IT city which is a mixed use development consisting of above commercial and residential areas.

Customer requirement:

Due to the mixed use requirement of the site, customer wanted to go for high delta T system which could serve both residential and commercial users.

Project development was planned in 2 phases, Carr and Hardy tower were developed in 1st phase and the rest in 2nd phase. Chilled water is distributed in a closed pipe net to energy transfer stations located in each of these individual towers.

THE SOLUTION

Air-conditioning:

Being a certified Green building customer required all pumps to have a minimum efficiency of 80% or more. Grundfos offered LF, LFE range of end suction pumps for primary, condenser & tertiary pump duties and for secondary pumps of 4600 usgpm horizontal split case pumps of KP models were offered.

Control MPC EF version with Grundfos CUE drives of 110 kW was offered to control secondary chilled water distribution pumps.

Mixing loop controllers located at these energy transfer stations ensure that these towers are supplied with chilled water at right temperature for optimum cooling comfort. Tertiary pumping systems of Control MPC EF were offered with Grundfos CUE drives of 30 kW combined with mixing loop controller MLC 3000.

Data from secondary, tertiary and mixing loop control systems were hooked up to the building management system through Modbus protocols.

THE OUTCOME

Now with all 4 towers commissioned, TRIL Info Park has become the first Indian commercial building to get ISO 50001 certification for energy management.
