Humidity control in data centres
Evaporative cooling in data centres
It is estimated that data centres consume 1 to 1.5% of global electricity, with some projections suggesting by 2030 this figure could be 3 to 4%. Cooling typically accounts for 30 to 40% of this energy use.
Direct and indirect evaporative cooling systems offer data centres a 30-70% energy reduction when compared to compressor-driven refrigeration. Evaporative cooling can enhance free-air cooling when outdoor temperatures exceed indoor requirements and can improve heat rejection in hybrid liquid cooling systems.
Condair provides standard and custom evaporative cooling solutions for data centres. The Condair ME in-duct system offers efficient, scalable cooling, while Kuul Evaporative Media can be used in AHUs or OEM cooling products to maximise evaporative performance.

Data centre humidification
Low indoor humidity can lead to electrostatic discharge, potentially damaging electronics and affecting server performance in data centres. For this reason, standard data centre design commonly specifies a minimum humidity level of 20%RH.
To achieve this humidity alongside a supply air temperature of 18°C, any data centre in a climate that drops to 0°C will need to use humidification at some time of the year.
Condair has a comprehensive range of humidifiers for data centres, ranging from steam units for CRAC systems to fully customised evaporative technologies for penthouse ventilation of hyperscale data centres.

Data centre dehumidification
High humidity in data centres presents a risk of condensation on cold surfaces, such as server racks, underfloor air plenums and chilled water lines. This in turn could lead to short circuits and equipment failure, or mould growth and structural damage.
ASHRAE recommends a maximum 80%RH humidity in A1 and A2 data centres for this reason. However, typical design condition is often a maximum of 60%RH.
Condair works with major data centre operators around the world to keep humidity levels optimal whilst minimising energy consumption. Desiccant technologies can be employed with heat recovery options to make the most of the waste heat generated in data centres, whilst condensing systems offer flexibility and ease of installation.

Use cases
Anti-static and ESD prevention
Low humidity increases static build-up because dry air is an insulator, making electrostatic discharge (ESD) more likely. Maintaining 40–60% relative humidity helps dissipate charges and significantly reduces ESD risk.
In-duct evaporative cooling
Condair in-duct evaporative cooling provides adiabatic cooling and humidification in AHUs, reducing cooling load and energy use for data centres, HVAC and industry.
Indoor evaporative cooling with humidification
Adiabatic evaporative cooling with additional air humidification lowers the room temperature, saves energy and improves the indoor climate – ideal for industrial, office environments and data centers.
Humidification boosts the immune system
Controlled humidity in buildings protects the self-cleaning function of the mucous membranes, reduces the risk of infection and strengthens the immune system. Dry air promotes respiratory diseases. Additional humidification ensures healthy indoor air and strengthens the immune system.

Microsoft, Ireland
Microsoft Dublin uses an "open air cooling" system rather than mechanical chillers to maintain the low internal temperatures required around its servers. Fresh air is continuously introduced into the building and mixed with recirculated indoor air.
35 Condair evaporative humidifiers provide up to 8°C of energy-efficient evaporative cooling to its huge data rooms. This combined use of fresh air and evaporative cooling has enabled the data centre to eliminate the need for mechanical cooling for 95% of the year.

Cork Internet Exchange
The Condair ME evaporative humidifier is providing adiabatic cooling in an innovative indirect cooling system from EDPAC at the Cork Internet Exchange (CIX) in Ireland. EDPAC's indirect air-to-air evaporative cooling system will be maintaining the temperature across CIX's data halls without using any chillers and with 75% less energy than a traditionally cooled data centre. The EDPAC air handling system cools without chillers by creating two airstreams one internal and one external. The internal airstream circulates air to and from the data halls and the external airstream draws in, then vents, ambient outside air. Both airstreams pass through a series of heat exchangers to transfer cool thermal energy from the external to the internal airstream, without either physically mixing.In order to boost the cooling capacity of the system, and keep the data halls at 24°C all year round, evaporative cooling is used to reduce the temperature of the external airstream below that of the ambient outdoor air.
Apple Campus, Cupertino
Cupertino, California, located close to San Francisco, is home to the headquarters of American technology company Apple. The building was designed by British architect Norman Foster, who realized the idea of an oversized ring in connection with the former Apple Campus at Infinite Loop No. 1 in Cupertino.
At a diameter of almost half a kilometre (461 m), the building complex offers a gigantic usable area of 260,000 m2 and space for 12,000 employees. The ring contains a 130,000 m2 park with rest areas, cafés, sports facilities and a rainbow-coloured festival stage, which was inaugurated by Lady Gaga in 2018. Powered entirely by renewable energy,
the building features a 17-megawatt rooftop solar energy system and energy-efficient evaporative cooling from Condair.
