[0025] The filtering and dust removal chamber 5 is provided with a first filter 501, a plasma dust removal module 502, an electrostatic dust removal module 503 and a second filter 504 which are vertically arranged side by side; the first filter 501 and the second filter 504 are both arc-shaped structures, and the concave surfaces of the first filter 501 and the second filter 504 correspond to the air inlet direction.

[0026] A nano water ion sterilization module 19 is also provided in the outlet static pressure chamber 8 .

[0027] The air inlet 2 is connected to a return air duct 201 and a fresh air duct 202 via pipelines.

[0028] like Figure 2 As shown, the controller 13 is also connected to the heat exchanger 9, the humidifying device 10 and the fan 11 respectively.

[0029] A method for using a digital air handling unit, wherein the device adopts the aforementioned digital air handling unit, and comprises the following steps:

[0030] S1. Set the processing parameter index of the air handling unit;

[0031] S2. Monitor the outside air through the air monitoring sensor group at the air inlet and upload the monitoring data to the controller:

[0032] S3. The controller controls the corresponding processing equipment in the dehumidification chamber, the filtration and dust removal chamber, the heat exchange chamber, the humidification chamber and the outlet static pressure chamber to perform corresponding processing work according to the monitoring data and the set processing parameter indicators;

[0033] S4, the air is discharged from the air outlet after being processed, and the air monitoring sensor group at the air outlet monitors and uploads the monitoring data to the controller;

[0034] S5. The controller displays the air monitoring data before and after entering the air handling unit through the display screen and uploads it to the remote control center.

[0035] The heat exchange monitoring sensor group includes a flow sensor, a temperature sensor at the inlet and outlet of the heat exchanger, and an electric control valve arranged at the inlet and outlet of the heat exchanger.

[0036] Furthermore, the first filter screen and the second filter screen are multiple in number and are arranged side by side in the filtering and dust removal chamber.

[0037] Preferably, the first filter screen and the second filter screen both include an upper filter screen and a lower filter screen that cooperate with each other, and the upper filter screen and the lower filter screen are rotatably connected to the filter and dust removal chamber.

[0038] The inner top surface and the inner bottom surface of the filtering dust removal chamber are both provided with accommodating grooves corresponding to the shapes of the upper filter screen and the lower filter screen, a rotating shaft is provided on one side of the accommodating groove, and a pull-out slide groove is provided on the rotating shaft; the sides of the upper filter screen and the lower filter screen are both provided with pull-out sliders that cooperate with the pull-out slide grooves.

[0039] The cross sections of the pull-out slide groove and the pull-out slider are both T-shaped structures.

[0040] With the above structure, on the one hand, the corresponding number of first and second filters can be selected in parallel according to the actual air processing volume, and by setting the first and second filters as a rotating two-stage split structure, the upper filter and the lower filter are hidden in the accommodating groove when not in use, and the two are rotated 90 degrees when in use, and the two cooperate with each other to form the first filter or the second filter, thereby meeting the processing requirements of different quantities. On the other hand, the upper filter and the lower filter are connected to the rotating shaft in a plug-in manner, so that the upper filter and the lower filter can be easily replaced, and the arc-shaped filter is also convenient for collecting dust.

[0041] The use process of the present invention is as follows: when in use, the outside air enters the inlet static pressure chamber from the air inlet (the air equalization treatment is performed in the inlet static pressure chamber), and the air is monitored by the air monitoring sensor group. When the humidity is greater than the set value, the air enters the dehumidification chamber for dehumidification, and then enters the filter dust removal chamber for dust removal. When the humidity is less than the set value, the dehumidifier in the dehumidification chamber does not work; then, when cooling treatment is required, the air enters the heat exchange chamber, and the refrigerant circulates in the heat exchanger to perform cold treatment on the air; when heating is required, the heat medium flows in the heat exchanger to perform heating treatment on the air; then, the air enters the humidification chamber, and if humidification treatment is required, the humidification device performs humidification treatment, and then enters the outlet static pressure chamber, and after the sterilization treatment by the nano water ion sterilization module, it is discharged from the air outlet under the action of the fan.

[0042] Humidity sensors are provided in the dehumidification chamber and the humidification chamber; a temperature sensor is provided in the heat exchange chamber.

[0043] Working process of the filtering and dust removal chamber: When air enters the filtering and dust removal chamber, it is first filtered by the first filter, then filtered by the plasma dust removal module and the electrostatic dust removal module, and finally filtered by the second filter to complete the filtering and dust removal operation of the air.

[0044] When the air needs to be humidified, the humidification device in the humidification chamber will perform humidification so that the air humidity reaches the set value.

[0045] The wall panels of the box body are made of double-layer colored copper plate or cold-rolled steel plate powder sprayed (the inner side of the base is sometimes made of stainless steel), and the middle insulation material is made of high-quality polyurethane foamed wall insulation material. Polyurethane foamed wall insulation material is more suitable for the occasions where the air handling unit is running at high speed and the box body vibrates greatly.
