Computer Room
Computer Rooms can be controlled in various ways, however when installing a system some important considerations must be taken into account.
Basic Computer/Server Control
These smaller computer/server room applications can be cooled with certain ‘comfort cooling’ air conditioning systems.
These systems can cool down to 21°C, which is more than sufficient for the computer equipment and have the following features:
- head pressure control – allowing for cooling throughout the winter
- auto power restart – the system would restart after a power failure
Dedicated Close Control
The 'comfort cooling' systems outlined above have a few drawbacks especially in the larger computer rooms, as follows:
- lower sensible heat ratio – dedicated units have a higher SHR
- they continually cool with no humidity control – low humidity can cause static issues
With the use of a ‘close control system’ we could offer full heating, cooling, humidification and de-humidification control.
These console units can be configured in three major ways, listed in order of preference:
- down flow - blowing conditioned air through a floor void and up through floor grilles
- up flow - utilising ductwork above the ceiling or ‘on show’ suspended
- free blowing – simply blowing directly into the room
Close control systems are ideal where accurate control of temperature and humidity within given parameters are required.
