11 is a block diagram showing a configuration for controlling a module and an air conditioning module according to an embodiment of the present invention. 12 is a flowchart for operating the thermoelectric module of the module according to an embodiment of the present invention.

Hereinafter, a control method between a module for introducing air into a module and an air conditioning module will be described with reference to FIGS. 11 and 12 .

The lower cabinet according to the present embodiment can grasp the relative humidity between the module and the air conditioning module, and control the structure of the module and the air conditioning module to operate in conjunction with each other.

Referring to FIG. 11, the lower cabinet 10 according to the present embodiment includes a first humidity sensor 410 that detects the humidity of air sucked into the suction part of the air conditioning module 300 and A second humidity sensor 420 detects the humidity of the air, and a third humidity sensor 430 detects the humidity of the internal space 202 of the module 200.

Referring to FIG. 12, the control unit 400 determines whether the humidity inside the module detected through the third humidity sensor 430 is equal to or greater than the third set humidity (S100), and the humidity inside the module is When the humidity is equal to or higher than the third set humidity, a step of operating a fan disposed at the module inlet 260 (S110) is performed. When the fan 290 disposed at the module inlet 260 is operated, air outside the module 200 is introduced into the module.

However, in the case of a module in which air must be continuously introduced into the module, the step of (S100) is omitted and the fan 290 inside the module 200 can be continuously operated.

The control unit 400 determines whether the humidity of the air sucked into the suction unit 310 of the air conditioning module 300 is equal to or less than the first set humidity (S130). The humidity of the suction part 310 of the air conditioning module 300 is detected by the first humidity sensor 410 disposed in the suction part 310 .

Since the air introduced into the suction part 310 of the air conditioning module 300 flows into the module suction port 260 of the module 200, when the air flowing into the suction part 310 of the air conditioning module 300 is dry air This is because the thermoelectric module 230 does not have to operate.

The control unit 400 determines whether the air conditioning module heater 370 is operating when the humidity of the air introduced into the suction unit 310 of the air conditioning module 300 is equal to or greater than the first set humidity (S200). This is because when the air conditioning module heater 370 in the air conditioning module 300 is operating, the air flowing inside the air conditioning module 300 is heated and the relative humidity is lowered.

When the air conditioning module heater 370 is not in operation, the controller 400 operates the thermoelectric module 230 inside the module 200 (S210). When the thermoelectric module 230 operates, the air introduced into the module inlet 260 passes through the thermoelectric module 230 in the drying passage and is discharged into the space of the module in a warm and dry state.

When the air conditioning module heater 370 is operated, the control unit 400 determines whether the humidity of the module inlet 260 is equal to or less than the second set humidity (S300). The humidity of the air sucked into the module inlet 260 is sensed through the second humidity sensor 420 . This is to prevent the thermoelectric module 230 from operating separately when the air conditioning module heater 370 operates and the relative humidity of the air introduced into the module is low.

When the humidity of the module inlet 260 is equal to or greater than the second set humidity, the controller 400 operates the thermoelectric module 230 . When the thermoelectric module 230 is operated, moist air introduced into the drying passage 220 of the module 200 is discharged into the module in a warm and dry state.
