In this process, the filter layer filters and dries particles and moisture in the outside air.
When the temperature inside the distribution box is less than the outside temperature and the inside air humidity is greater than the outside humidity. The first ventilation assembly is used as an exhaust assembly, the exhaust fan starts to rotate positively, the three-way regulating valve of the first ventilation assembly closes the filtering pipeline and opens the direct blowing pipeline, so that the high-humidity gas in the distribution box is discharged out of the distribution box through the direct blowing pipeline. In the process, high-humidity air in the distribution box blows the outer surface of the filter layer through the air blowing port, so that floating dust on the outer surface of the filter layer is blown off, and the filtering service life of the filter layer is prolonged.
Simultaneously, the second subassembly of taking a breath is as the subassembly of admitting air, and its exhaust fan begins to reverse, and the three-way governing valve of the second subassembly of taking a breath closes the direct-blowing pipeline, opens the filter pipeline, inhales the low-humidity air in the block terminal outside through the filter pipeline in the block terminal, realizes the dehumidification in the block terminal. Meanwhile, the heat dissipation and the temperature reduction of electronic components in the distribution box are realized through the air circulation flow. In this process, the filter layer filters and dries particles and moisture in the outside air.
When the temperature inside the distribution box is less than the outside temperature and the inside air humidity is less than the outside humidity. The first ventilation assembly and the second ventilation assembly are both inactive.
In the above process, the timer calculates the usage time of the first ventilation assembly continuously as the exhaust assembly and the second ventilation assembly continuously as the intake assembly.
If the service time of the first ventilation assembly continuously serving as the exhaust assembly and the second ventilation assembly continuously serving as the air inlet assembly exceeds the time threshold, the first ventilation assembly is used as the air inlet assembly, the filter layer on the first ventilation assembly is maintained, and the drying and/or filtering performance of the filter layer on the second ventilation assembly is maintained. The use mode can prolong the whole use time of the ventilation assembly and can also ensure the constant temperature and humidity in the distribution box.
Example 4
Based on the embodiments 1-3, the air circulation system of the distribution box is further disclosed in this embodiment with reference to fig. 3 of the specification.
In order to protect the filter layer 56 and the air blowing port 55, the ventilation unit 5 is installed in the ventilation space 13 at the lower part of the distribution box.
As is well known in the art, hot air is relatively light and often accumulates in the upper air, so that the exhaust fan 54 of the ventilation assembly 5 is disposed at the bottom of the distribution space 12, which affects the efficiency of exhaust and intake.
In order to avoid this problem, the present embodiment further installs a lower fan 15 on the upper surface of the partition 11, and an upper fan 14 on the lower surface of the top plate of the distribution space 12, where the lower fan 15 and the upper fan 14 rotate in one forward direction and in one reverse direction to circulate the air in the distribution space 12, so as to homogenize the temperature and humidity of the air in the distribution box, and ensure the ventilation efficiency of the ventilation assembly.

It is important to note that the gap between the wire of the second temperature sensor and the threading hole is sealed, so as to avoid the influence of the air in the distribution box on the measurement precision of the second temperature sensor.
Meanwhile, the lower case 71 is made of a heat insulating material to prevent the temperature on the distribution box from being transferred to the lower case 71 to affect the measurement accuracy of the second temperature sensor.
The top case 72 is made of a heat conductive material to ensure accurate conduction of the outside air suit to the sensing probe 73, to ensure measurement accuracy of the second temperature sensor, and to protect the sensing probe 73 from being damaged.
The second humidity sensor is disposed in a second sensing module (not shown), and the second sensing module is substantially identical to the first sensing module in terms of arrangement and structure, and is different in that the second sensing module does not have a top shell 72, and the second humidity sensor passes through a threading hole and enters the lower shell 71, so that the top of the sensing probe 73 is flush with the top of the lower shell 71, and the sensing probe can be protected from being damaged on the premise of ensuring the measurement accuracy of the second humidity sensor.
