Abstract

The invention provides a method and system for testing room ventilation times based on a carbon dioxide release source, and the method comprises the steps: obtaining indoor personnel information, and determining a CO2 emission rate based on the personnel information; calculating a current indoor CO2 concentration calculation value based on the emission rate, the assumed room permeation air volume, the room volume and the currently detected outdoor CO2 concentration value; calculating an estimated value of the CO2 concentration based on the calculation value and the calculation error; and when the difference value between the estimated value and the currently detected indoor CO2 concentration value meets the preset condition, the number of times of room ventilation is calculated according to the assumed room permeation air volume. According to the method, the indoor ventilation quantity is iteratively solved under the condition that the maximum measurement error of the estimated value and the measured value is guaranteed, and then the ventilation frequency of the room is obtained. The workload of measuring the ventilation times in the room is simplified, the measurement cost is reduced, and the hourly ventilation times of the room can be conveniently detected.

Description

technical field [0001] The invention relates to the technical field of building energy-saving testing, in particular to a testing method for room ventilation times based on carbon dioxide release sources. Background technique [0002] In recent years, as my country continues to promote the development of building energy conservation, the airtightness level of buildings is getting higher and higher, and at the same time it also brings problems such as poor room air quality. Furniture, decoration, office supplies, etc. in the room will volatilize a large amount of pollutant gas, which is harmful to people's health; there is not enough fresh air in the room, and the concentration of carbon dioxide is high, which is not only not conducive to people's life, but also more likely to produce mold, mildew It will also accelerate the aging of the building when it is generated in the wet corner, and the fresh air entering the room will inevitably generate building loads and increase bu...
