Abstract
Disclosed is a humidity control apparatus which ensures a sufficient dehumidification amount without increasing an area of a gas-liquid contact portion in a dehumidification unit, regardless of the type of liquid absorbent used. The humidity control apparatus includes an absorbent circuit connecting a liquid-based dehumidification module, a recovery module, and a liquid-cooling heat exchanger which cools, with a refrigerant, a liquid absorbent before being used in the liquid-based dehumidification module. A refrigerant-cooling-based dehumidification module is positioned upstream of the liquid-based dehumidification module in a flow direction of target air, and cools and dehumidifies, with the refrigerant, the target air before being dehumidified in the module. The liquid-cooling heat exchanger and the refrigerant-cooling-based dehumidification module are connected to a single refrigerant circuit together with a liquid-heating heat exchanger.
