AIR TREATMENT DEVICE, DEVICE FOR CONTROLLING AIR TREATMENT DEVICE, AND METHOD FOR CONTROLLING AIR TREATMENT SYSTEM AND AIR TREATMENT DEVICE

Provided are an air treatment device, a device for controlling an air treatment device, and a method for controlling an air treatment system and an air treatment device in which efficient absorption and release of moisture are realized using a moisture absorbing/releasing solution at a small quantity and a low concentration throughout the year, whereby a reduction in size and cost can be attained and durability can be obtained. This invention has: an air supply path 100 for supplying outside air to an air conditioned space R; a temperature adjustment unit 20 installed on the air supply path 100, the temperature adjustment unit 20 adjusting the temperature of the outside air so that the specific enthalpy of the outside air becomes equal to a prescribed value; a humidity adjustment unit 23 installed on the downstream side of the temperature adjustment unit 20 on the air supply path 100, the humidity adjustment unit 23 having a gas-liquid contact member to and through which the moisture absorbing/releasing solut
