PROBLEM TO BE SOLVED: To attain energy saving of an air conditioning system by a method wherein the air-conditioning system includes an air conditioner that circulates indoor air for air-conditioning and an outside-air-conditioning unit that treats and supplies the outside air into a room and is provided with a desiccant to absorb moisture in the outside air and a heat pump that serves as a heat source for regenerating the desiccant. SOLUTION: A room is air-conditioned by circulating the inside air via an air conditioner and additionally provided with an outside-air-conditioning unit to treat and supply the outside air into the room. The outside-air-conditioning unit has an outside air leading path A and an inside air discharge path B and is provided with a desiccant rotor 103 that repeatedly absorbs moisture and releases moisture (regeneration), a sensible heat exchanger 104 and a heat pump 200 that serves as a heat source for regenerating desiccant between the paths A and B. The outside air supplied by a fan 102 exchanges heat with the return air (regeneration air) and cools down at the sensible heat exchanger 104 after moisture in the outside air is absorbed by a moisture absorbent of the desiccant rotor 103, and is supplied into the space of the room through a path 111 after further cooled down by a cooler 210. |
