Problems solved by technology

The forced mechanical ventilation of the kitchen and bathroom is used in Chinese residential buildings. The forced mechanical ventilation includes the kitchen smoke exhaust system (range hood), bathroom ventilation system (ventilation fan), etc., which are used to instantly remove the indoor accumulated smoke. Pollutants, but the design level of the current exhaust duct is uneven, and the residential exhaust has serious smoke, odor, and cross-contamination. When the kitchen and bathroom pollution sources are partially exhausted, the residence does not have a stable supply of fresh air.
In actual operation, the mechanical ventilation operates constantly under the design air volume, and the continuous mechanical exhaust consumes a lot of energy, which is contrary to my country's energy-saving requirements

Embodiment 1

[0026] The outdoor fresh air enters the room through the air inlet 1 for fresh air supply. The detectors are arranged in the parts with serious indoor air pollution: bedrooms, living rooms, kitchens, and bathrooms. The exhaust outlets are arranged in Figure 1. The indoor air quality signal is detected by the detector 2. The signal is an analog signal. Since the detected analog signal is weak, in order to convert it into a digital signal more accurately, the collected analog signal is first input to the linear amplifier and amplified for processing. Then the amplified analog signal is input to the A / D conversion module, and the digital signal output after the A / D conversion is transmitted to the processor 3 for numerical processing, and the current air condition is judged according to the numerical value. The quality status, thereby determining the current suitable switching status of the exhaust fan 8. This value is directly sent to the sending end of the wireless transmitter ...

Embodiment 2

[0028]The outdoor fresh air enters the room through the air inlet 1 for fresh air supply, and the indoor air humidity signal parameters are detected by the humidity detector 2. The signal is an analog signal. Since the detected analog signal is weak, in order to convert it into a digital signal more accurately, the collected The incoming analog signal is input to the linear amplifier, amplified to the maximum allowed by the processor 3, and then the amplified analog signal is input to the A / D conversion module, and the digital signal output after the A / D conversion is transmitted to Numerical processing is carried out in the processor 3, and the current air humidity is judged according to the numerical value, thereby determining the current suitable switching state of the exhaust fan 8. This value is directly sent to the sending end of the wireless transmitter 4 via the output interface of the processor 3, and then the sending end transmits the control signal to the wireless te...

Embodiment 3

[0030] The outdoor fresh air enters the room through the air inlet 1 for fresh air supply, and detects the indoor air carbon dioxide concentration and air humidity signal parameters through the carbon dioxide detector and humidity detector. The signal is an analog signal. Since the detected analog signal is weak, in order to convert more accurately To convert the digital signal into a digital signal, first input the collected analog signal to the linear amplifier, amplify it to the maximum allowed by the processor 3, and then input the amplified analog signal to the A / D conversion module, which will undergo A / D conversion The final output digital signal is transmitted to the processor 3 for numerical processing, and the current indoor air quality state is judged according to the numerical value, thereby determining the current suitable switch state of the exhaust fan 8 . This value is directly sent to the sending end of the wireless transmitter 4 via the output interface of the...

Abstract

The invention relates to a mixing ventilation and gas-exchanging device, which consists of an inlet air part, a signal detection analysis and conversion processing part, an exhaust air part, a transmission part and a receiving and execution part. The inlet air part is an air inlet; the signal detection analysis and conversion processing part consists of a detector and a processor; the transmission part is a wireless transmission device; the receiving and execution part consists of a wireless terminal, a frequency conversion controller and an exhaust fan; the exhaust air part consists of an air outlet and an exhaust fan; an output end of a probe is connected with the processor, and an output end of the processor is connected with the wireless transmission device which is connected with the wireless terminal through wireless signals; the wireless terminal and the frequency conversion controller are connected, and the frequency conversion controller is connected with the exhaust fan. By detecting the thickness and the humidity of indoor carbon dioxide, and utilizing the wireless transmission to control the operation condition of the exhaust fan, the device realizes mutual conversion of natural ventilation and mechanical ventilation, thus meeting such requirements as energy conservation, improvement of air quality and thermal comfort condition, reduction of transport cost of air conditioner as well as prolonging service life of facilities etc.

Description

(1) Technical field: [0001] The invention relates to a hybrid ventilation control device for civil buildings, which is to intelligently control the conversion between natural ventilation and mechanical ventilation by detecting indoor air quality parameters and transmitting signals through wireless transmission equipment to control the operation of the system, which belongs to ventilation and ventilation devices. (two) background technology: [0002] The purpose of residential ventilation design is to eliminate residual heat, residual humidity and air pollutants in residential rooms; to maintain indoor thermal balance and air volume balance by introducing fresh air and removing dirty air. [0003] The traditional residential ventilation methods in my country are mainly natural ventilation and forced mechanical ventilation. Natural ventilation is an economical ventilation that does not require any energy costs. However, with the development of building energy conservation, the...
