Description

Technical Field

[0001] The present invention relates to the technical field of fresh air purification, and more specifically, to a ductless intelligent fresh air system. Background Art

[0002] Currently, the control logic of existing fresh air systems mainly focuses on manual, timed, and fixed-point air exchange, lacking a dynamic perception and response mechanism for indoor environmental quality. Especially in scenarios where there are differences in air quality in different rooms, the system cannot adjust the ventilation strategy in real time. Moreover, traditional control methods can also cause the indoor temperature to decrease or increase when the fresh air is working in winter and summer, resulting in a waste of energy.

[0003] In addition, the installation of traditional fresh air machines also requires pre-burying complex fresh air ducts in advance. The duct layout occupies the indoor floor height, which is extremely likely to damage the aesthetics of the building. Moreover, it is difficult to transform a decorated house, and there are problems such as high construction costs and long cycles.

[0004] For the above problems, there is currently no effective solution. Summary of the Invention

[0007] Further, the indoor air quality includes formaldehyde, benzene, toluene, xylene, ammonia, total volatile organic compounds, oxygen, carbon dioxide, air temperature, air humidity, and PM2.5.

[0008] Further, the communication connection method is at least one of a data line, Wi-Fi, or Bluetooth.

[0009] Further, the room temperature fluctuation is controlled within the range of ±1°C.

[0010] Advantages of the present invention: The present invention compares and analyzes the detected data with the set room temperature value through the main controller, and sends the analysis result to the partition wall-mounted fresh air fan and the main exhaust fan to control the air volume, achieving precise ventilation and air exchange. Moreover, the main controller also collects real-time weather data through networking, and automatically adjusts the temperature by comparing the real-time weather data with the set room temperature value. At night in summer, it compares the real-time weather data with the indoor temperature, effectively avoiding waste of resources and large fluctuations in room temperature. This application solves the problems of complex construction technology, high cost, and energy waste during use in traditional fresh air control systems, and reduces the construction difficulty and cost. It is also suitable for installation in rooms that have been renovated. BRIEF DESCRIPTION OF THE DRAWINGS

The main controller 1 gives a working signal through data analysis and sends it to the partition wall-mounted fresh air fan 3 and the main exhaust fan 4.

[0020] The partition air quality detector 2 detects the indoor air quality and transmits it to the main controller 1 through data transmission (such as data line, Wi-Fi, Bluetooth, etc.).

[0022] Considering that the temperature is low in the summer evenings, the room ventilation is poor, the indoor is stuffy and the outdoor is cool, an air temperature adjustment function is added. The main controller 1 is connected to the network to collect real-time weather data. The real-time weather data is compared with the indoor temperature, and the fresh air replacement volume in the room is automatically adjusted to achieve the purpose of temperature adjustment. The main controller 1 sets the cooling and heating modes. By comparing the real-time weather data with the room temperature set value, through the partition wall-mounted fresh air fan 2 and the main exhaust fan 4, the indoor temperature is automatically adjusted.

[0023] The main controller 1 of the present invention can also be replaced. The partition air quality detector 2 detects data and directly controls the wall-mounted fresh air fan 3. Each partition air quality detector 2 has the functions of the main controller 1.

Moreover, it can be installed before or after the decoration, reduces the labor construction period, prevents large fluctuations in the indoor temperature, and avoids waste of energy.

[0025] In summary, with the above technical solutions of the present invention, the detection data is compared and analyzed with the room temperature set value by the main controller, and the analysis result is sent to the partition wall-mounted fresh air fan and the main exhaust fan to control the air volume, realizing precise ventilation and air change; moreover, the main controller is also connected to the network to collect real-time weather data, and the fresh air replacement volume in the room is automatically adjusted and the temperature is adjusted by comparing the real-time weather data with the room temperature set value.
