The table shows the energy consumption and cooling effect at different humidification methods.

Only when using steam for humidification there is no cooling effect because the evaporation energy is supplied in the shape of electricity, before the steam is supplied to the air. Humidification with steam will on the contrary result in a further temperature increase in the room during the summer period.

In each single case it is necessary to dimension the humidification system and calculate the humidity need throughout the year, depending on the actual ventilation, heat and recovery conditions, and of course the wanted temperature and humidity conditions.
