The fresh air dehumidification system performs a dehumidification mode.

When it is detected that H≥H1, as shown in Figure ₂ , the air intake damper 51 and the exhaust damper 52 are controlled to be in the closed state, the circulation damper 53 is in the open state, and the indoor air passes through the wind direction regulator 4 and the downwind outlet 3. After the circulating damper 53 flows into the processing unit 1 and is processed, it is discharged by the wind direction regulator 4 through the upper air outlet 2 .

When H ₁ ≥ H ≥ H ₂ is detected, as shown in Figure 3, the air intake damper 51, exhaust damper 52 and circulation damper 53 are not fully opened at this time, and the indoor air passes through the air direction regulator from the lower air outlet 3 4 and the circulating damper 53 flow into the treatment unit 1 for treatment, and then are discharged through the wind direction regulator 4 through the upper air outlet 2.

It should be noted that the temperature factor may not be considered at this time.

Example 2:

The difference between Embodiment 2 and Embodiment 1 is that the fresh air dehumidification system executes the ventilation mode at this time.

If the detected harmful gas density is greater than the air density, as shown in Figure 4, control the air intake damper 51 and the exhaust damper 52 to be in an open state, and the circulation damper 53 to be in a closed state, and the indoor air passes through the air direction regulator from the lower air outlet 3 4 and the exhaust damper 52 are discharged, and ambient gas enters the room from the upper air outlet 2 through the air intake damper 51 through the processing unit 1 and the wind direction regulator 4 .

If the detected harmful gas density is lower than the air density, as shown in Figure 5, control the air intake damper 51 and the exhaust damper 52 to be in an open state, and the circulation damper 53 to be in a closed state, and the indoor air passes through the wind direction regulator from the upper air outlet 2 4 and the exhaust damper 52 are discharged, and ambient gas enters the room from the lower air outlet 3 through the air inlet damper 51 through the processing unit 1 and the wind direction regulator 4 .

It should be noted that temperature and humidity may not be considered at this time.

Example 3:

The difference between Embodiment 3 and Embodiment 1 is that the fresh air dehumidification system implements the temperature adjustment mode at this time.

If it is detected that _T >TS, as shown in Figure 6, the system adopts the method of downdraft and updraft, and the gas processed by the processing unit 1 is discharged into the room through the upwind port 2, and the indoor air is drawn out through the downwind port 3 .

If it is detected that _T <TS, as shown in Figure 7, the system adopts the method of upward draft and downward air intake, and the gas processed by the processing unit 1 is discharged into the room from the lower air outlet 3, and the indoor air passes through the upper air outlet 2 pull out.

It should be noted that, at this time, the humidity and air quality can be ignored, and only the circulation damper 53 is set to be in an open state in the air intake regulator 5; The exhaust damper 52 is in an open state, and the circulation damper 53 is in a closed state.

Or, when the fresh air dehumidification system is in use, it can also be set that the user can control the fresh air dehumidification system to switch between different working modes, for example: when the fresh air dehumidification system is in the dehumidification mode, if the humidity meets the corresponding dehumidification requirements , the dehumidification action will be performed normally, otherwise the system will automatically enter the standby state; when the fresh air dehumidification system is in the ventilation mode, if the indoor air quality meets the ventilation requirements, the ventilation action will be performed normally, otherwise the system will automatically enter the standby state; When the fresh air dehumidification system is in the temperature adjustment mode, if the indoor temperature meets the temperature adjustment requirements, the temperature adjustment operation will be performed normally, otherwise the system will automatically enter the standby state.

Or, considering that the outdoor air may be polluted, an outdoor air detection device (used to detect the outdoor air quality, such as PM2.5 concentration or whether it contains harmful gases such as sulfur dioxide, etc., is provided outside the setting, the detection device is prior art) , when it is detected that the outdoor air quality is lower than the set air quality requirement, the system controls the air intake regulator 5 to perform an internal circulation action.

The above is only a specific embodiment of the present invention, but the scope of protection of the present invention is not limited thereto. Anyone skilled in the art can easily think of changes or substitutions within the technical scope disclosed in the present invention. Should be covered within the protection scope of the present invention. Therefore, the protection scope of the present invention should be determined by the protection scope of the claims.
