Benefits of direct air humidification for new and existing buildings
A lack of maintenance of central air-conditioning systems and the associated issues with building hygiene have, in some cases, brought air humidification into disrepute. However, it is often overlooked that an alternative humidification method has long proven its worth, particularly in industrial applications: in-room air humidification. This means that any building, including office buildings, can be fitted with a professional humidification system – whether installed directly in new builds or retrofitted in existing buildings is irrelevant.
The direct alternative:
The simple and flexible installation of in-room humidification makes these systems particularly attractive for retrofitting. For buildings where there is no central ventilation system, or where humidification within a ventilation and air-conditioning system (HVAC system) is not feasible due to insufficient humidification distances or excessive costs, in-room humidification offers an ideal and cost-effective solution. Compared to other centralised humidification technologies, high-pressure nozzle systems with an energy consumption of 0.7 kW also incur very low energy costs.
The complete absorption of the micro-fine atomised water droplets in the air causes additional heat to be extracted from the room. This is a positive side effect, as many modern buildings, particularly office buildings, suffer from excessive heat loads today. The adiabatic cooling effect can effectively support the use of air conditioning. For every kilogram of water that evaporates into the air via the nozzle humidification system in one hour, a cooling capacity of 640 W can be achieved.
Comparison of the basic principles
Direct air humidification
In-room humidification, standalone humidification systems are installed in the room to be humidified and operated individually via atomisers.
Indirect air humidification
The air is humidified in the chambers of a ventilation and air-conditioning system and fed into the work areas via ducts and outlets.
A sensible combination
However, the general question of whether the required humidity is best provided indirectly via the HVAC system or via direct humidification cannot be answered in a generalised manner in all cases.
Depending on the on-site structural conditions and the building user’s requirements, a combination of indirect and direct humidification may also be sensible: Indirect humidification then ensures the basic humidity level, whilst direct humidification provides additional spot humidification in defined areas.
The advantage of in-room air humidification lies fundamentally in the more targeted humidity control. This allows areas with different uses to be humidified individually and according to need. This ‘spot humidification’ is particularly cost-effective for the client when only specific areas, such as floors, departments or work areas, are to be humidified. However, there are further advantages to direct air humidification.
