Abstract

The purpose of this invention is to ensure a sufficient amount of dehumidification regardless of the type of liquid absorbent used without increasing the area of the gas-liquid contact unit in a dehumidifying unit. A liquid dehumidification module (21), a regeneration module (31), and a liquid cooling heat exchanger (46) that cools, using a refrigerant, a liquid absorbent before the liquid absorbent is used in the liquid dehumidification module (21) are connected to an absorbent circuit (15). A refrigerant cooling dehumidification module (48) is located further on the upstream side in the flow direction of the air to be processed than the liquid dehumidification module (21) and cools and dehumidifies the air to be processed before the air is dehumidified by the module (21) with the refrigerant. The liquid cooling heat exchanger (46) and the refrigerant cooling dehumidification module (48) are connected to a single refrigerant circuit (40) along with a liquid heating heat exchanger (44).
