Beyond this, there are other key differences between close control and comfort cooling systems:
Close control systems are designed to handle high density heat loads - they move significantly larger volumes of air compared to comfort cooling systems.
Close control systems provide control of relative humidity - data centres have very specific relative humidity requirements. Too high and condensation and corrosion can occur, too low results in an increase in static electricity. Close control systems are designed to provide an accurate ratio of cooling, humidification and dehumidification to meet these needs, whereas comfort cooling systems generally offer no control over relative humidity.
Close control systems offer greater filtration - equipment housed in data centres is highly sensitive to dust and other particulates. As such, close control systems use much higher grade filters than their comfort cooling counterparts.
Close control systems are designed for continual operation - as cooling is a constant requirement in mission critical environments, they’re capable of running 24/7 year round, unlike comfort systems which are designed for limited daily use in the summer months.
Close control systems are designed to handle high density heat loads. They have a higher sensible heat ratio, and are used on a constant basis for close control of temperature and relative humidity.
Comfort air conditioning is designed for both sensible and latent cooling at low density heat loads. It is made for intermittent use to create comfortable conditions for people.
