Exemplary method
On the basis of the above embodiment, the present invention also provides an indoor wind balance control structure for use in any one of the above embodiments, including:
step S100: obtaining the indoor and outdoor pressure difference value of the indoor air-conditioning area 1, wherein the pressure difference value is the difference value obtained by subtracting the outdoor air pressure from the indoor air pressure;
specifically, the indoor and outdoor differential pressure values are obtained through the differential pressure sensor 102 arranged in the indoor air conditioning area 1, specifically, the differential pressure sensor 102 can be installed by arranging an installation hole on a wall body for installing the indoor air conditioning area 1 or communicating an installation channel between the indoor and the outdoor, and the invention is not specifically limited, and the indoor and the outdoor pressure values are detected through detection heads arranged outdoors and indoors, and the differential pressure values are based on the indoor differential pressure and the outdoor differential pressure.
Step S200: and judging whether the pressure difference value is smaller than a preset pressure difference value or not, and when the pressure difference value is smaller than the preset pressure difference value, adjusting the ventilation quantity of the first ventilation pipeline 105 to allow outdoor air to enter the indoor toilet area 2 based on the pressure difference value.
Specifically, referring to fig. 3, the step S200 further includes:

Step S203: the electrically controlled regulating valve increases the ventilation of the first ventilation duct 105 into the indoor toilet zone 2 based on the percentage.
Specifically, the preset differential pressure value can be tested according to the actual installation environment to obtain preset storage, and the preset storage is called when needed. For example, the standard value of the indoor and outdoor pressure difference is 5 Pa. The preset differential pressure value is 5Pa, the differential pressure sensor 102 transmits a detected differential pressure signal to an automatic control logic unit (DDC), the control logic unit (DDC) converts the received differential pressure signal into a voltage signal, the voltage signal is transmitted to an air valve regulation control mechanism (electric regulating valve 104) to be received, the air valve regulation control mechanism (electric regulating valve 104) converts the voltage signal into a regulating valve opening signal, and the opening of the regulating valve is regulated through an executing mechanism so as to control the ventilation volume of the first channel.
Examples are: indoor and outdoor differential pressure is reduced to 4Pa (indoor and outdoor differential pressure is reduced by 20%), the differential pressure sensor 102 transmits the signal to an automatic control logic unit (DDC), the DDC outputs a corresponding voltage value according to the self range (the DDC transmission voltage is usually 0-10V, the set value of the indoor and outdoor differential pressure corresponds to the voltage value, when the indoor and outdoor differential pressure is reduced by 20%, an adjusting valve with the opening of 20% is correspondingly opened (the adjusting valve is an air valve), then the DDC outputs a 2V voltage signal), the voltage output by the DDC reaches an air valve adjusting controller (the adjusting range of the opening of the air valve is 0-100%, when the 2V voltage is received, namely the indoor and outdoor differential pressure is reduced by 20%, the air valve adjusting controller adjusts the opening of the air valve to 20%, and the opening of the air valve is controlled to 20%. When the indoor and outdoor pressure difference is greater than 5Pa, the DDC outputs a 0V voltage signal, namely, the DDC does not output a signal, the opening degree of the electric control valve is kept unchanged, the electric control valve is in a default closing state, and at the moment, the first channel does not enter outdoor air.

The electric control valve 104 is used as a control mechanism for the bypass outdoor air volume, the reduction of the frequency of the indoor variable frequency fan leads to the reduction of the air volume (the fresh air volume introduced into the second channel) sent into the room, and the air volume exhausted to the outside by the fixed frequency fan (the exhaust equipment 106 realizes exhaust through the fixed frequency fan) is constant, so the indoor and outdoor pressure difference is reduced under the condition, the pressure returns to the normal value again by the air outside the bypass room entering the room, the reduction range of the indoor and outdoor pressure difference is different, the bypass air volume is different, namely, the opening degree of the bypass valve (the electric control valve 104 in the second channel) is different, and the electric control valve 104 is used for adjusting the bypass air volume, so that the indoor and outdoor pressure difference is stable.
Obtain the indoor outer differential pressure value of indoor air conditioning district 1 through differential pressure sensor 102 to judge whether indoor outer differential pressure value is less than predetermineeing the differential pressure value, realize the detection to indoor outer differential pressure, work as when the differential pressure value is less than predetermineeing the differential pressure value, based on the differential pressure value is adjusted the air volume of first air pipe 105 lets in outdoor wind and avoids indoor outer differential pressure to the too big indoor air conditioning district malleation value of indoor outer differential pressure to be less than predetermineeing the differential pressure value or reduce and form the negative pressure and cause outdoor pollutant because the pressure differential gets into indoorly to 2 balanced indoor outer differential pressures in indoor bathroom.
Further, referring to fig. 4, on the basis of the above embodiment, the step S100 of obtaining the pressure difference value between the indoor air-conditioning area 1 and the outdoor air-conditioning area includes:
step S10: monitoring the concentration of carbon dioxide in the room;
step S11: and adjusting the air volume of the second channel based on the indoor carbon dioxide concentration.
The air volume of the second channel is adjusted by monitoring the concentration of indoor carbon dioxide and based on the concentration of the indoor carbon dioxide, so that the fresh air volume introduced into the room can be flexibly adjusted.
Specifically, the concentration of the indoor carbon dioxide is detected by a carbon dioxide concentration detector 103 provided in the indoor air conditioning section 1.
Specifically, the adjusting the air volume of the second channel based on the indoor carbon dioxide concentration includes: judging whether the carbon dioxide concentration is smaller than a preset indoor standard carbon dioxide concentration, and when the carbon dioxide concentration is smaller than the preset indoor standard carbon dioxide concentration, calculating a reduction value of the indoor carbon dioxide concentration based on the preset indoor standard carbon dioxide concentration; then, the ventilation quantity of the second ventilation pipeline 101 is adjusted to supply outdoor air to the indoor air conditioning area 1 based on the reduction value. The standard indoor CO2 concentration should not exceed 1000ppm, and the standard indoor CO2 concentration is set to 1000ppm (preset indoor standard carbon dioxide concentration). When indoor CO2 concentration detector detected indoor CO2 concentration and was less than 1000ppm, transmitted concrete numerical value to automatic control logic unit (DDC), the DDC converted this data into the signal of telecommunication, and the signal of telecommunication is received by the converter of frequency conversion fan (flat fan is used for control the new trend that lets in the second passageway), converts the signal of telecommunication into the frequency signal of adjusting inverter motor to adjust inverter motor's power frequency, inverter motor's rotational speed is with inverter motor's frequency positive correlation, inverter motor power frequency's change direct control inverter motor's rotational speed change.
Examples are: the indoor CO2 concentration is reduced to 800ppm (the CO2 concentration is reduced by 20%), the carbon dioxide concentration detector 103 transmits the detected concentration value to the automatic control logic unit DDC, the automatic control logic unit DDC outputs a corresponding voltage value according to the self measuring range (the DDC transmission voltage is usually 0-10V, 5V is an intermediate value, the corresponding CO2 concentration of the value is set to be 1000ppm, when the CO2 concentration is reduced by 20%, 4V voltage is output), the voltage output by the DDC reaches a frequency conversion fan frequency converter controller (the frequency range of a fan motor is 0-50Hz, when 4V voltage is received, namely the CO2 concentration is reduced by 20%, the frequency converter adjusts the power utilization frequency value of the fan motor to 40Hz), the frequency conversion fan motor frequency is controlled to be 40Hz, namely, the power frequency is reduced by 20%, and the rotating speed of the frequency conversion fan is correspondingly reduced by 20%. When the concentration value of CO2 is greater than or equal to 1000ppm, namely the DDC outputs 6-10V voltage, the fan frequency conversion controller controls the motor to run at the maximum frequency (50Hz), and the corresponding fan rotating speed is at the maximum value.
