The integrated indoor unit adopts a central ceiling installation, and the cold and hot source fresh air is sent to each room through the indoor air supply pipeline. Centralized and decentralized flexible management is adopted, and each room can independently adjust and control the room air environment to achieve energy-saving measures allocated on demand. When the user only uses one room for a long time, only the temperature, humidity, CO2, and PM2.5 values ​​required by the room are set. The system will automatically open the room branch air valve of the room, and the room branch air valves of other rooms are closed. The air conditioner outdoor unit and the integrated indoor unit are operated at low gear and opened intermittently, and only the cold and hot source fresh air of the set room is supplied. This on-demand allocation scheme effectively saves the energy consumption of the machine.

[0027] like Figure 1-Figure 4As shown, a room air environment intelligent control system proposed by the present invention includes a fresh air device, a humidity sensor, a temperature sensor, an air quality sensor, an air quality adjustment device, a temperature control device, a pipe network 2, a human body detection module and a control module;

[0028] The output end of the fresh air device is connected to the fresh air connecting pipe 11, and a solenoid valve b13 is arranged on the fresh air connecting pipe 11. There is no air outlet of the fresh air device in the bathroom; the humidity sensor and the temperature sensor are arranged in the room, and are used to detect the humidity and temperature in the room respectively. At least one set of humidity sensor and temperature sensor is arranged in each room, and the humidity sensor and temperature sensor in each room are given different marking names. The bathroom is marked as bathroom temperature sensor and bathroom humidity sensor, and the room is marked as room temperature sensor and room humidity sensor; the temperature control device is arranged in the room, and the output end of the temperature control device is connected to the temperature control connecting pipe 12. The temperature control device is used to output cold air or hot air. A solenoid valve c14 is arranged on the temperature control connecting pipe 12; the pipe network 2 is arranged at the bottom of the roof 1 and above the suspended ceiling 6. The pipe network 2 is a plurality of groups of horizontal pipes 8 and a plurality of groups of vertical pipes 9 vertically connected to form a mesh pipeline. Both ends of the horizontal pipes 8 and the vertical pipes 9 are closed. The output end of the pipe network 2 is connected to the pipe network input pipe 15. The pipe network input pipe 15, the temperature control connecting pipe 12 and the fresh air connecting pipe 11 are connected through three The through valve 10 is connected, and an air outlet branch pipe 3 is arranged at the bottom of the intersection of the longitudinal pipe 9 and the transverse pipe 8. An electromagnetic valve a4 is arranged on the air outlet branch pipe 3. The air outlet branch pipe 3 cooperates to pass through the through hole 7 on the ceiling 6. A filter screen 5 is arranged at the air outlet end at the bottom of the air outlet branch pipe 3. The room is divided into multiple local spaces 16 with the air outlet branch pipe 3 as the center; a human body detection module is arranged in the room to identify human faces and detect the position of people, and to identify the mutual distance between multiple people. The human body detection module's face recognition is completed by a camera, and the detection of the position of a person is completed by an infrared sensor, and then the mutual distance between multiple people is calculated by graphic processing technology; air quality sensors and air quality adjustment equipment are both arranged in the room to detect the air quality in the room. The air quality sensors include carbon dioxide sensors, formaldehyde sensors and PM2.5 sensors; the control module humidity sensor, temperature sensor, air quality sensor and human body detection module are all connected for data transmission, and the control module is controlled and connected with the fresh air equipment, air quality adjustment equipment and temperature control equipment.

[0029] Working principle: Input different personal information and air environment intention parameters. Determine whether someone is bathing, and combine with the personnel detection before entering the bathroom to determine the specific person, control the operation of the fresh air equipment and temperature control equipment according to the air environment intention parameters set by the person, and adjust the air environment parameters in the room that the person is about to enter after bathing. When there are multiple people in the room, identify the specific person, call up the air environment intention parameters set for each person, and then judge the distance between the people according to their positions. When the distance is greater than the set distance, create a different temperature range for each local space 16 by adjusting the opening or closing of multiple solenoid valves a4. When the distance between the people is less than the set distance, the optimal air environment parameters in the room are obtained according to the air environment intention parameters of the two people and combined with a specific algorithm, and the temperature is controlled by the temperature control equipment. For example, the set distance is set to one meter. When the distance between the two people is greater than one meter, different solenoid valves a4 can be controlled to open to Different temperatures are created for different local spaces 16, because the airflow blows directly below the outlet branch pipe 3, the cold air or hot air in this area must radiate around with the local space 16 as the center, and the temperature change in this area is most obvious. When the distance between people is less than one meter, the algorithm is used to calculate the best room air parameters, which can only meet the personalized needs of different people as much as possible.
