Problems solved by technology
[0002] With the development of building technology, people's pursuit of comfort, high-grade and intelligent building indoor environment is getting higher and higher. At this time, the air tightness of residential buildings has become an important link to improve the quality and quality of buildings. The detection methods of building airtightness are tracer gas concentration attenuation method and air pressure method. However, these two methods measure the indoor airtightness by the number of air changes. inaccurate question

The invention discloses a residential building indoor air tightness detection method and system. When the scheme is applied, the method comprises the steps of: obtaining the air pressure data of the indoor space of the target building, performing feature extraction to obtain the air pressure distribution state, analyzing the air permeation state obtained in advance, and further screening out the first part with the updated air pressure distribution state; and extracting a second part in the air pressure distribution state to obtain a target air pressure distribution state, and further performing classification processing on the target air pressure distribution state so as to count the number of the data change curve graph; and finally, obtaining the mapping relation between the number of the data change curve graphs and the air pressure data in the same time period to obtain change information, judging whether an information description value corresponding to the change information issmaller than a preset threshold value or not, and judging whether the air tightness of the indoor space of the target building meets set conditions or not. The indoor air tightness can be measured without the need for the number of times of air exchange, so that the indoor air tightness of the building can be accurately detected.
Description
technical field [0001] The present disclosure relates to the technical field of indoor air tightness detection of buildings, in particular to a method and system for indoor air tightness detection of residential buildings. Background technique [0002] With the development of building technology, people are pursuing more and more comfort, high-end and intelligent building indoor environment. At this time, the air tightness of residential buildings has become an important link to improve the quality and quality of buildings. The detection methods of building airtightness are tracer gas concentration attenuation method and air pressure method. However, these two methods measure the indoor airtightness by the number of air changes. Inaccurate question. Contents of the invention [0003] In order to improve the technical problems existing in related technologies, the present disclosure provides a method and system for detecting indoor air tightness of residential buildings. ...
