PROBLEM TO BE SOLVED: To realize energy saving in a dehumidification system for dehumidifying a humidity controlled space using a dehumidification unit including an adsorption heat exchanger and an adsorption rotor.SOLUTION: A dehumidification system (10) comprises: an adsorption rotor (31) extending over an air supply path (40) and a regeneration air path (50); and a dehumidification unit (20) including a refrigeration circuit (20a) in which two adsorption head exchangers (22, 24) are connected. The dehumidification system (10) includes a refrigeration circuit (50a) that includes: a heat collection heat exchanger (68) provided downstream of a regeneration-side adsorption heat exchanger on the regeneration air path (50); and a regeneration heat exchanger (65) provided upstream of the adsorption rotor (31) on the regeneration air path (50), and circulates refrigerant between the heat exchangers (68, 65) so that the heat collection heat exchanger 68 collects heat from regeneration air to transfer the heat to refrigerant, and so that the collected heat is conveyed to the regeneration heat exchanger (65) to transfer the heat to the regeneration air. |
