The problem: existing facilities – new requirements

And in many cases, the often-used method of “heating and ventilation” also cannot solve the humidity problem. This principle makes use of the physical effect that environmental air can retain more humidity at higher temperatures. With this process, an extreme amount of energy must be used for heating and ventilation to attain the necessary temperatures and air circulation.

In any case, this method cannot be used in refrigerated areas and other low-temperature environments – and without a corresponding increase in air temperature, an increase in air circulation alone in these areas would have no effect on the rate of evaporation.

Refrigerated areas cannot be reduced to the desired humidity values without using dehumidification systems. Although the cooling systems reduce the temperature of the working areas to the required low temperatures of 0 to 12 °C, the functional principle of cooling systems has no relevant effect on air humidity, which cannot be reduced below 70 to 95 % relative air humidity by using the cooling systems alone.
