Problems solved by technology

However, if the fresh air volume introduced is not adjusted and controlled, and it is always operated at the maximum air volume, there will be two negative effects
On the one hand, the filter element of the fresh air fan needs to be replaced soon, which is costly, and it is even more unfeasible to postpone the replacement. During this period, the filter element will become a source of air pollution instead, resulting in poor indoor air quality
On the other hand, introducing too much fresh air into the room will bring a great burden to the indoor air conditioner, which not only does not save energy, but also cannot ensure a suitable temperature and humidity for the indoor environment.

Abstract

The invention discloses a control method for automatically adjusting the blowing rate of a fresh air ventilator. The control method includes the following steps that S1, the indoor CO2 concentration value P is detected; S2, the detected indoor CO2 concentration value P is compared with a preset threshold value, and the threshold value interval range of the CO2 concentration value is judged; and S3, according to the interval range obtained in the step S2, a control unit accordingly adjusts the opening degree of a fresh air valve, and if the value within the interval range is larger, the corresponding opening degree of the fresh air value is larger. Through the control method, the fresh air quantity introduced into a room is automatically adjusted, the service life of a filtering element isprolonged, and the use cost is lowered.

Description

Technical field [0001] The invention relates to the technical field of indoor air quality control, in particular to a control method for a new fan to automatically adjust the air volume. Background technique [0002] At present, with the rapid development of cities, the air quality in cities continues to decline, and new fans are becoming more and more popular, becoming a common household appliance after air conditioners. After being filtered by the filter element of the fresh air blower, the outdoor air becomes clean fresh air and is sent indoors, effectively improving the indoor air quality. However, if the introduced fresh air volume is not adjusted and controlled, and it has been running at the maximum air volume, there will be two negative effects. On the one hand, the filter element of the new fan needs to be replaced soon, which is costly, and delayed replacement is even less feasible. During this period, the filter element will become a source of air pollution, resulting...
