Air feed air channel 6 is connected with, electric heater 4 is installed in air feed air channel 6, humiture collection device 2 is installed on the end of air feed air channel 6
Air outlet at, the port of export of humidifier 3 is connected with humidification pipeline 7, and humidification pipeline 7 is filled with electric heater 4 and humiture collection
The air feed air channel 6 put between 2 is connected；The one side of control module 1 is electrically connected with humiture collection device 2, on the other hand respectively
Electrically connected with humidifier 3, electric heater 4 and refrigerating plant 5.
In the present invention, humidification pipeline 7 and air feed air channel 6 are perpendicular.
The sectional area for humidifying pipeline 7 is consistent with the sectional area in air feed air channel 6.
Below in conjunction with accompanying drawing, the present invention is further illustrated：
The refrigerating capacity of refrigerating plant 5 is linear adjustable (and provided with minimum input amount, that is, opening the cold at least put into), and electricity adds
The power of hot device 4 is linear adjustable, and the humidification amount of humidifier 3 is linearly adjustable, and the rated power of electric heater 4 is slightly larger than or is equal to
The rated cooling capacity of refrigerating plant 5, the specified humidification amount of humidifier 3 should be enough.It is linearly adjustable to refer to allowing the model of adjustment
Enclose, control signal and maximum, minimum value one-to-one corresponding that output quantity is proportional relationship, control signal and output quantity.Control
Module 1 is that by the module of function of the present invention, and it should comprise at least two input quantities (temperature, humidity), three output quantities
(linear control signal, the linear control signal of electric heater 4, the linear control signal of humidifier 3 of refrigerating plant 5) is specifically adjusted
Section according to water capacity formula, calculates inlet and outlet water capacity by control module 1, to determine whether to put into refrigerating plant, according to going out
