For example, the residual amount of chemical liquid, the concentration of chemical liquid in the working space, etc. are analyzed and compared with the current state of the corresponding chemical liquid vaporizer, and if excessively operated, the amount of operation is reduced. Unlike this, if the corresponding chemical liquid vaporizer is operated insufficiently, the amount of operation is controlled to increase.

Of course, for this purpose, a lookup table may be configured in advance in the database 12-1 of the management server 12. If this is represented in a table, it is as follows. Of course, there are identification numbers for distinguishing the first to nth chemical vaporizers 300a to 300n and the first to nth work spaces, which are stored in a database or chemical vaporizer in advance. Also, for the sake of understanding, it is assumed that one chemical liquid vaporizer is installed per work space.

Through the above data management module 920, as a result of the analysis, the concentration of the current chemical solution in the first workspace, the second workspace, the fourth workspace, and the n-th workspace is higher than the reference concentration of the vegetable solution stored in the database in advance. .

Of course, this control information may include the operation time and operation period of the air compressor 100 and the vibration generator 200. For example, the operation time may be about 10 minutes and the rest period for stopping the operation may be about 20 minutes, and an operation cycle repeating this four times may be mentioned.

In addition, the control information may include information for controlling the operation time based on the spray amount by calculating the spray amount of the liquid medicine tank 400 in advance. That is, it is possible to calculate the injection amount per minute as an experimental value in advance, store it in the database, and set the operating time for several minutes in order to eject a certain amount of injection amount. To elaborate, if 2 ml per minute, it can be mentioned that continuous operation for 30 minutes produces a spray volume of 60 ml.
