Energy usage

Humidifiers with a low energy usage
For humidifying energy is required. The energy required to evaporate water is always 0.68 kW per litre water per hour. This energy can be supplied conventionally by producing steam in the humidifier itself or can be taken from the air like an adiabatic humidifier does. The right choice of the humidifier can result in savings of 75% or more on the energy costs, especially when there is an internal heat load available!For humidifying energy is required.

Isotherm or adiabatic

For adiabatic humidification the energy to evaporate the water is taken out of the environment. Worst case this means that you have to provide additional heating, where the energy is provided by a high efficient heating in contrast to steam humidification.

In the best case you are pleasantly surprised because you get free cooling (for example in a production hall with heat producing machinery). With isothermal humidification steam is produced, in general using electricity and sometimes with gas fired humidifiers or industrial steam boilers.

Energy savings

Before you can save money, you have to spend some. Cumulus® her goal is to offer the most energy efficient humidification for your specific situation. We investigate in which manner you can offer the best service to your customer by for example supplying an energy comparison. The amount of energy, required to evaporate water, is a physical fact. However the way this energy is supplied, makes a big difference, Based on this route, two principal design exist; adiabatic humidification and isothermal humidification.

Concretely speaking, this has the following consequences for an averag office building:

The Energy Performance Coefficient goes up with 1% for adiabatic humidification and 8% for electrical steam humidification

 

The energy costs are for adiabatic humidification 4x (!) lower than electrical steam humidification

 

The CO2 emission is for adiabatic humidification 3x (!) lower than electrical steam humidification
