Data and Switch Centers

Introduction

Enova has been at the forefront of designing cooling systems for Data Centres.

We have used water-cooled centrifugal chillers with dual piping network. We have also used air cooled chillers with ring main, PHE and Precision type air handlers.

​

Key considerations

​

• Use of several High Delta T air-cooled chillers with inlet and outlet temperatures being 18 degrees C and 26 degrees C respectively,

• Ease of scalability.

• Evaporative cooling pads on condensers to reduce power consumption.

• Chillers with Quick Start feature.

• Water supply to CRAH units through PHE that allows for different Data Halls to maintain different temperatures.

• Positive pressurisation of Data Halls and ancillary spaces to prevent corrosion of IT equipment thereby enhancing their durability and reliability.

• Use of DX system for effective moisture removal from fresh air to control Room RH.

• Hot or Cold aisle containment.

• Provision for adding thermal storage system in future.

• Project target PUE: 1.30.

• Comfort cooling of office spaces with VRF system.
