As is clear from the above description of the embodiments, the present invention can realize an excellent dehumidifying / humidifying machine having the following effects. (1) When the space to be conditioned and the air other than the space to be conditioned are introduced, the operation is controlled by measuring the temperature and humidity. Therefore, the operation can be performed in the optimum mode, and the humidity of the humidified space can be quickly adjusted. (2) The operation mode includes a manual operation. Therefore, it is possible to respond to a user's request regardless of the state of air. (3) In the dehumidification mode operation, the dehumidification ventilation mode operation is performed at regular intervals. For this reason, air pollution in the humidified space can be reduced. Further, this ventilation dehumidifies the air supply, so that even if the introduced air is humid, the air in the humidified space can be ventilated without increasing the humidity. (4) The humidification ventilation mode operation is performed at regular intervals during the humidification mode operation. For this reason, air pollution in the humidified space can be reduced. Further, since this ventilation humidifies the supply air, even if the introduced air is low in humidity, the air in the humidified space can be ventilated while keeping the humidity. (5) The operation mode includes a preheat ventilation mode operation. In ventilation and the like in winter, since the supply air is heated and introduced, the temperature of the humidified space does not decrease, and the heating load can be reduced as compared with the case of only ventilation.
