り制御が簡単になる。In the air conditioning method of the above (1), if the extension line of the line connecting the temperature and the target temperature of the air on the wet air line diagram intersects with the saturation curve of the wet air line diagram, the extension line and the saturation curve The temperature and humidity of the air changes toward the target temperature and humidity on the line connecting the air temperature and the target temperature and humidity on the psychrometric chart by showering the shower water with the temperature controlled to the temperature at the intersection of I do. Then, by controlling the amount of water in the shower to an amount such that the temperature and humidity of the air becomes the target temperature and humidity, conditioned air with the target temperature and humidity can be obtained. Therefore,
Since the air-conditioned air is obtained by showering the temperature-controlled shower water to the target temperature and humidity, the control becomes simpler than the conventional air-conditioning method. In the air conditioning method of the above (2), if the extension line of the line connecting the air temperature and the target temperature and humidity on the humid air chart does not intersect with the saturation curve of the humid air chart, Temporarily adjust the air until it reaches the temperature and humidity on the line that crosses the saturation curve after passing the target temperature and humidity, and the temperature at the intersection of the extension line of the line that connects the temporarily adjusted air temperature and humidity and the target temperature and humidity, and the saturation curve The temperature and humidity of the temporarily adjusted air are showered to the air, and the temperature and humidity of the temporarily adjusted air are set to the target temperature and humidity on the line connecting the temporarily adjusted air temperature and target temperature and humidity on the psychrometric chart. Change towards. Then, by controlling the amount of water in the shower to an amount such that the temperature and humidity of the air becomes the target temperature and humidity, conditioned air with the target temperature and humidity can be obtained. Therefore, the air-conditioned air is obtained by showering the temperature-controlled shower water on the temporarily adjusted air until the target temperature and humidity are reached,
Control becomes simpler than the conventional method. In the air conditioning method of the above (3), when the line connecting the temperature and the target temperature of the air on the wet air chart is parallel to or the same as the enthalpy line of the wet air chart, the shower water is showered to the air. Accordingly, the temperature and humidity of the air change toward the target temperature and humidity along the enthalpy line on the psychrometric chart. Then, by controlling the amount of water in the shower to an amount such that the temperature and humidity of the air becomes the target temperature and humidity, conditioned air with the target temperature and humidity can be obtained. Therefore, irrespective of the temperature of the shower water, the conditioned air can be obtained simply by showering the shower water to the target temperature and humidity, so that the control is simpler than the conventional method.

得られる。When the air-conditioned air is exhausted from the air-conditioned room 1, the temperature and humidity of the air-conditioned air are measured by a thermo-hygrometer 8. The measurement result is transmitted to the water volume controller 12 and compared with the target temperature and humidity. If the measured temperature and humidity match the target temperature and humidity, the current amount of water is maintained. When the measured temperature and humidity are on the line b ', a signal for increasing the amount of water in the hot water shower is transmitted from the water amount controller 12 to the pump 13, and when the measured temperature and humidity are on an extension of the line b'. Is the water flow controller 12
A signal for suppressing the amount of water in the hot water shower is transmitted to the pump 13. As a result, conditioned air having the target temperature and humidity O is obtained.
