A humidity control system (10) includes a refrigerant circuit (50) in which an adsorption heat exchanger (51, 52) carrying an adsorbent thereon is connected. During a regeneration action of a humidification operation of the humidity control system (10), outdoor air passes through the adsorption heat exchanger (51, 52) from upstream towards downstream in the flow of refrigerant. Therefore, the air can be effectively increased in temperature at the air inflow end of the adsorption heat exchanger (51, 52), thereby preventing freezing of dew condensation water. |
