Keep Your Data Centre Cool with Our Air Conditioning and Cooling Units
Ensuring your data centre is running at the correct temperature is a very important consideration.
We are specialists in the design and installation of critical close control air conditioning for data centre environments, including chilled water, glycol free cool, direct expansion and more recently, air cooled systems.
The design of the air conditioning system is critical to the efficiency and reliability of the site as the power requirements for air conditioning alone can be up to a third of the overall power consumption.
Increasing attention has to be paid to the efficiency of any data centre cooling system, with local authorities in particular requesting an energy conservation report to be submitted as part of any planning process. It is therefore imperative that the design optimises efficiency while still supplying the required cooling loads.
Various measures can be taken, including :-
- Making use of outside air for cooling when the ambient temperature does not exceed a set level. This saves on running costly air conditioning equipment.
- Items of equipment more tolerant of running in higher ambient temperatures may be segregated and supplied with vented non air conditioned air, making further savings.
- Correct setting out of computer racking into a hot and cold aisle configuration will ensure a direct hot air path back to the air handling equipment.
Chilled water systems can be used throughout larger data centres and computer rooms, when conditions allow they may be run in a compressorless free cool mode.
Chilled water systems utalise a single piperoute run throughout the facility to serve all data centre air handling units. This introduces a single point of failure within the facility which can be mitigated by using a tier 4 system.
Tier 4 will employ two sets of pumps and pipework supplying alternate air handling units through out the facility.
A cooling medium, typically gas, air or water from the data centre is passed through a heat exchanger, typically a cooling coil in the case of water.
Water is sprayed onto the heat exchanger which evaporates drawing heat out of the cooling medium.
The cooled medium is then recirculated back into the data centre.
The advantage of adiabatic cooling include reduced running costs compared to conventional air conditioning due to having no compressors involved in the cooling process and reduced maintenance costs due to the simplified nature of the equipment.
We are able to offer advice on the installation of these units either in a new data centre or replacing old conventional units in an existing data centre.
