Cooling
Cooling
EDC Data Centres are designed to meet the demands of the latest high density server technologies with greater efficiency and cost saving benefits. This is achieved through hot and cold aisles, maximising equipment layout, balancing airflows as necessary and tailoring the cooling to your dedicated suites.
High density readiness
EDC expects high density readiness will soon be a major factor in data centre selection, based on new high power servers available on the market today and being installed at EDC's new facility. This challenge has been addressed via the provision of chilled water connections and space ready for the installation of the heat exchanger module and overhead cooling equipment. These chilled water connections could also be used for "in-rack cooling" or a combination of both. This would allow for the flexibility to choose your preferred method of deploying high density computing equipment in local areas within each data room.
Lowest carbon footprint
Many organisations are beginning to think "Green" and EDC has designed solutions that will minimise the carbon footprint of our facilities. The design takes advantage of a number of factors such as evaporative free cooling via the redundant chilled water loop and the dual coil CRAC units, very low energy chillers, ducted return CRAC unit selections for sensible cooling only, optional thermal energy storage and variable speed pumping systems.
Multiple alternative cooling sources
The system will not rely only on the chillers for cooling. Other cooling systems will come into play depending on the operating mode and ambient conditions. These other systems include;
- dual coil CRAC units;
- evaporative free cooling via the redundant chilled water loop; and
- optionally thermal storage of chilled water in the standby water supply tank.
Dual coil and chilled water distribution
The chilled water distribution system is separated into two individual redundant loops and each CRAC unit has two individual coils so that in the event of a major water pipe failure the redundant loop can be utilised to continue cooling supply without downtime. The redundant loop is used in appropriate weather for free cooling to minimise the demand on the chillers.
Modular design for expansion and maintenance without interruption
The data centres are designed for modular expansion and maintenance to prevent disruption from this work to the continuous operations of the data centre.
