居住建筑通风净化软件IAQS研发及验证鉴于人们对居住建筑室内空气品质的

Residential building ventilation purification IAQS software development and validation <br><br>Given the importance of indoor air quality of residential buildings and residential buildings for indoor PM2.5 concentrations forecasting, analysis and evaluation software is more scarce, user-friendly, simple operation residential building ventilation purification Software (IAQS ) was developed in this study, and software building thermal environment DeST (BAS) and ventilation (Ventplus) analysis module is calculated based to simulate and predict the different forms of ventilation purification ventilation purification strategies at room temperature, CO2 concentration, PM2.5 concentration and building heating energy consumption of air conditioning and ventilation purification energy consumption. <br>Natural ventilation is further an example, each room in a building and a room for two simulation object, comparison and verification between IAQS EnergyPlus software, results showed that: both the room for a building, and EnergyPlus used IAQS 1) the average relative deviation calculation results when the CO2 concentration by 7.0%, average relative deviation calculation results when PM2.5 concentrations by 11.0%; 2) for two rooms of the building, two software calculation results by the average CO2 concentration the relative deviation is 18.9%, average relative deviation calculation results when PM2.5 concentrations by 20.6%. Calculates a deviation between the two substantially within reasonable limits, IAQS software reliability of the results thus confirmed. <br>[Key words] residential building; ventilation purification; PM2.5 forecasting; IAQS software; contrast verification

Research and development and verification of IAQS ventilation purification software for residential buildings<br><br>In view of the importance people attach to the indoor air quality of residential buildings and the lack of software for the prediction and analysis of PM2.5 concentration in residential buildings, the interface-friendly and simple operation of residential building ventilation purification software (IAQS) was developed in this study, and the DeST software's building thermal environment (BAS) and ventilation (Ventplus) computational analysis module sits to simulate the prediction of different forms of ventilation and ventilation ventilation and ventilation ventilation strategies under the indoor temperature, CO2 concentration, PM2.5 concentration and building heating and air conditioning energy consumption and ventilation purification energy consumption.<br>Taking natural ventilation as an example, the comparison between IAQS and EnergyPlus software was carried out as a simulation object for a room and two rooms, and the results showed that: 1) for a room building, the average relative deviation of the CO2 concentration of IAQS and EnergyPlus software was 7.0%, and the average relative deviation of PM2.5 concentration was 11.0% for two room buildings, and 2) for two rooms. The average relative deviation of the time-by-time calculation results of the two software CO2 concentrations was 18.9%, and the average relative deviation of the PM2.5 concentration-time-by-time calculation was 20.6%. The calculation deviation between the two is basically within a reasonable range, and the reliability of the IAQS software simulation results is confirmed.<br>Residential buildings; ventilation purification; PM2.5 prediction; IAQS software; comparative verification
