Humidifying device

A humidifying device comprising:

• a first thermometer configured to measure a temperature inside the humidifying device;
• a first hygrometer configured to measure a humidity inside the humidifying device;
• an air inlet;
• an internal air passage through which air taken in from the air inlet passes;
• an air outlet from which the air that has passed through the internal air passage is discharged;
• a cooler installed in a path of the internal air passage;
• and
• a hardware controller configured to execute at least one program to control the cooler,
• wherein the hardware controller changes a cooling intensity of the cooler in a case where values measured by the first thermometer and the first hygrometer are out of a predetermined range,
• wherein hardware controller is further configured to execute a program to:
• store a preset target humidity;
• calculate a water content per unit substance amount based on values measured by the first thermometer and the first hygrometer, respectively;
• calculate a target temperature by using the value calculated and the value stored by the target humidity storing unit;
• estimate a temperature that is reachable in a case where air at the temperature measured by the first thermometer is cooled by the cooler;
• and
• notify a user, and
• wherein the hardware controller is configured to control the notification to the user in a case where the target temperature calculated for the target temperature is higher than the temperature estimated by a predetermined value or more.

A humidifying method comprising:

• measuring a temperature by a first thermometer installed in a humidifying device;
• measuring a humidity by a first hygrometer installed in the humidifying device;
• determining whether the temperature measured by the first thermometer and the humidity measured by the first hygrometer are within a predetermined range;
• and
• controlling intensity of a cooler installed in a path between an air inlet and an air outlet,
• wherein the humidifying method further comprises:
• installing a second thermometer between the cooler and the air outlet;
• installing a second hygrometer between the cooler and the air outlet;
• detecting that dew condensation has occurred in the humidifying device, by using the temperature measured by the first thermometer, the humidity measured by the first hygrometer, the temperature measured by the second thermometer, and the humidity measured by the second hygrometer, and
• calculating a water content per unit substance amount by using the temperature measured by the first thermometer and the humidity measured by the first hygrometer, and
• calculating a water content per unit substance amount by using the temperature measured by the second thermometer and the humidity measured by the second hygrometer,
• wherein it is determined that the dew condensation has occurred in a case where a difference between 1) a value calculated for the water content per unit substance amount by using the temperature measured by the first thermometer and the humidity measured by the first hygrometer and 2) a value calculated for the water content per unit substance amount by using the temperature measured by the second thermometer and the humidity measured by the second hygrometer, is equal to or greater than a predetermined value, and
• different cooling intensities are set for the cooler in a case where it is determined that the temperature and the humidity are within the predetermined range and in a case where it is determined that the temperature and the humidity are out of the predetermined range.
