Based on the database of typical weather condition in northern cold region of China, this paper compares different function buildings' cooling and heating load's imbalance rate. The effect of different building functions on cooling and heating load is analyzed. On the above basis, underground heat exchanger pipe group model of ground source heat pump (GSHP) is established. As a monthly time step to...
This study attempted to find the typical concentration levels of bacterial and fungal bioaerosol in gymnasia in China. The air samples were collected using the 6-stage Andersen impactor inside and outside of buildings. It was found that the total concentrations of outdoor airborne bacteria and fungi were 342 CFUm-3 and 287 CFUm-3, respectively. The typical levels of bacterial and fungal aerosol indoors...
This paper described an application of artificial neural networks (ANNs) to predict the indoor air quality (IAQ). Six indoor air pollutants and three indoor comfort variables were used as input variables to the networks. An occupant symptom metric (PIAQ) was used as the measure of indoor air quality, and employed as the output variable.Pollutant concentration, comfort variable, and PIAQ data were...
