Humidification for data centers

In data centers, humidifiers primarily ensure that electrostatic discharges and damage
to sensitive hardware are prevented. In addition, evaporative coolers can be used in the exhaust air cooling system, thus significantly reducing operating costs for cooling the servers. The cooling effect achieved in the exhaust air is carried over to the intake air. Conventional cooling machines and cooling batteries can therefore be designed to be significantly smaller and more cost-effective. In addition to this, the ongoing operating costs for building cooling are reduced.

Reduce energy costs

Indirect evaporative cooling in air conditioning systems is one way of generating regenerative cooling capacity. The reduction of the capacity and power requirement of a cooling machine for mechanical cooling through indirect evaporative cooling is based on the thermodynamic principle that air cools when it is humidified through the evaporation of water. The evaporation heat needed for the phase change of water is removed from the air and causes the desired cooling.

The potential energy savings of this efficiency measure can be determined using an energy simulation calculation based on exemplary system parameters and meteorological data for the location. The cooling effect achieved in the exhaust air is carried over to the intake air. Conventional cooling machines and cooling batteries can therefore be designed to be significantly smaller and more cost-effective. In addition to this, the ongoing operating costs for building cooling are reduced significantly.

Static charges

Static charge can occur during maintenance work, or on ungrounded components in the data center. This can lead to uncontrollable discharge shocks and the destruction of sensitive electrical components.

At a relative humidity of 50–55%, damp air increasingly settles on ions, making them heavier and less mobile in the electric field. The conductivity of the air and the material surfaces then increases, so that electrical charges are dissipated, which prevents the formation of potential differences.
