Abstract
A system, and method for the dehumidification of airstreams for processes, production areas or residential buildings. The system comprises a conditioner for absorbing moisture from air into a liquid desiccant. The system comprises a desiccant dryer for evaporating the absorbed moisture from the liquid desiccant to evaporated moisture. The system comprises a condenser for condensing the evaporated moisture. The system comprises a heat transfer medium flow circuit arranged such that heat removed from the evaporated moisture during condensation in the condenser is absorbed by the heat transfer medium, and such that said heat is used in evaporation of the absorbed moisture from the liquid desiccant.
Claims29
An air dehumidification system, comprising:
- a conditioner for absorbing moisture from air into a liquid desiccant;
- a desiccant dryer for evaporating the absorbed moisture from the liquid desiccant to evaporated moisture;
- a condenser for condensing the evaporated moisture;
- a heat transfer medium flow circuit arranged such that heat removed from the evaporated moisture during condensation in the condenser is absorbed by the heat transfer medium, and such that said heat is used in evaporation of the absorbed moisture from the liquid desiccant, the heat transfer medium comprising a refrigerant;
- wherein the condenser comprises at least one cooling tube forming part of the heat transfer medium flow circuit and having a first surface for condensation of evaporated moisture thereon,
- wherein the heat transfer medium flow circuit comprises a compressor downstream of the at least one cooling tube.

A method for dehumidifying air, the method comprising:
- absorbing moisture from air into a liquid desiccant;
- evaporating the absorbed moisture from the liquid desiccant to evaporated moisture;
- and
- condensing the evaporated moisture;
- wherein heat released during condensation of the evaporated moisture is absorbed by a heat transfer medium, the heat transfer medium comprising a refrigerant, and wherein said heat is used in evaporation of the absorbed moisture from the liquid desiccant, the method further comprising compressing the heat transfer medium subsequent to condensing the evaporated moisture, wherein the heat transfer medium is pressurized such that heat transfer medium can change from vapour to liquid.
