Problems solved by technology
However, if, for example, the calibration of the outside air temperature and humidity sensor is inappropriate and there is an error between the actual temperature and humidity, it is impossible to set an appropriate state change prediction line.
In addition, as shown in Japanese Patent Application Laid-Open No. 11-83129, there is a possibility that unnecessary heating, humidification, and cooling may be performed by controlling to follow the predicted state change line.
Therefore, when controlling each device so that the supply air temperature and humidity follow the target temperature and humidity, the control becomes complicated.

Embodiment approach 1
[0027] (Embodiment 1) Hereinafter, an embodiment of the present invention will be described with reference to the drawings. use figure 1 The configuration of the air conditioner 1 according to Embodiment 1 will be described. The air conditioner 1 has an air-conditioning room 10 , an air supply port 2 provided at the entrance of the air-conditioning room 10 , and an air supply port 4 provided at the exit of the air-conditioning room. The air conditioner 1 supplies air-conditioned air obtained by taking in outside air from the air supply port 2 and air-conditioned by the air conditioning room 10 through the air supply port 4 to an area to be air-conditioned, such as a painting booth.
[0028] A front heater 12 , a rear heater 14 , a dust removal device 16 , a humidity adjustment device 20 , and an air blower fan 28 are installed in the air-conditioning room 10 . The front-stage heater 12 is provided on the upstream side of the humidity adjustment device 20 . In addition, the ...

An air conditioner (1) is configured to set the temperature and humidity at a point on a target curve as a target temperature and a target humidity, respectively, corresponding to at least one of a supply air temperature and a supply air humidity. In addition, the supply air temperature regulator (110) is configured to adjust in such a manner that based on the deviation between the supply air temperature (Tα) and the target temperature (Tt), the front heater (12), the humidity adjustment device (20) and the rear At least one of the stage heaters (14) is controlled so that the supply air temperature (Tα) follows the target temperature (Tt). In addition, the supply air humidity regulator (112) is configured to adjust in such a manner that based on the deviation between the supply air humidity (Mα) and the target humidity (Mt), the front heater (12), the humidity adjustment device (20) and the rear At least one of the stage heaters (14) is controlled so that the humidity of the supplied air (Mα) follows the target humidity (Mt).
Description
technical field [0001] The invention relates to an air-conditioning device and an air-conditioning control method, in particular to an air-conditioning device and an air-conditioning control method for adjusting the temperature and humidity of air supply. Background technique [0002] In paint booths for automobiles, it is required to maintain high paint quality. Therefore, it is necessary to install an air conditioner that can adjust the temperature and humidity in the painting room with higher precision. For example, Japanese Patent Laid-Open No. 11-83129 discloses a temperature and humidity control device for air-conditioned air, which has a main heating device with variable heating capacity in order to adjust the sucked outside air to a preset temperature and humidity. Adiabatic humidifier with variable humidification capacity, cooling device with variable cooling capacity, auxiliary heating device with fine adjustment of heating capacity, and auxiliary humidifier with ...
