Abstract

The present invention relates to a system for controlling humidity in a defined space and a method for controlling humidity in a defined space using the system. More specifically, the invention relates to a system for controlling humidity in a defined space, the system comprising: an active air conditioner fluidly connected to the defined space; a control device operably coupled to the active air conditioner; at least one hygrometer arranged in the defined space and operably coupled to the control device; a passive dehumidifier and humidifier comprising hygroscopic material, which passive dehumidifier and humidifier is configured to be accommodated in the defined space and in contact with the air in the defined space. The present invention also relates to a method for controlling humidity in a defined space using such a system.Background artDehumidifiers, such as sorption dehumidifiers and condensate dehumidifiers, are used for separating and removing moisture from air. A sorption dehumidifier typically comprises a dehumidifying element in the form of a wheel or rotor holding desiccant material, which is effective in attracting and retaining water vapour. The desiccant rotor may be divided in two sections, a process section and a regeneration section. The airflow to be dehumidified, process air, will pass through the process section of the desiccant rotor, the desiccant material in the rotor extracts moisture from the process air, so that it can leave the rotor as dried air.Simultaneously, the desiccant material is regenerated by another air stream, which flows through the regeneration section, all the while the desiccant rotor may rotate slowly about its longitudinal axis. By means of the simultaneous dehumidification of the process air and regeneration of desiccant material, the dehumidifier can be operated continuously.US2007056307 discloses an example of a dehumidifier having a desiccant wheel.Document US20200408425A1 discloses a device adapted to control temperature and humidity of the air in a room. The device consists of elements of a quantity of hygroscopic material and means for passing air past or through the elements. A fan provides forced convection of air in a desired path over or through the hygroscopic material in the elements. The system may stabilize variations in temperature and humidity by cyclic absorption and evaporation matching the changes in external humidity.
