Natural ventilation potential analysis of rural residential buildings in China

International Conference on Electric Information and Control Engineering (2011)

Lei Ya-ping Zhongping Lin Fu Xiao

This paper presents the method of natural ventilation potential analysis of rural residential buildings based on the relationship between the building external climate and the indoor acceptable thermal environment, and the basic theory of natural ventilation. The natural ventilation potential of rural buildings was calculated in ten different areas covered five climate areas in China. Finally, the different effective factors of natural ventilation potential such as acceptable indoor air temperature, building orientation and heat gain were discussed.

Uncertainty Analysis on Air Flow Rate Measured by Multiple Nozzles in Chamber for Test Rig for Air Filter

Journal of Tongji University (2012)

Lei Ya-ping

The paper presents an uncertainty analysis on air flow rate measured by multiple nozzles in chamber for the test rig for air filter.The results show that the precision of the nozzles' diameter is remarkable to the systematic uncertainty.Different nozzle combinations will result in different uncertainties.Adopting the appropriate nozzle with smaller diameter at the same air flow rate can reduce the measurement uncertainty effectively.The manufacturing precision of nozzles should be validated simultaneously.The accuracy of the instruments influences the measurement the most,while instruments for dry bulb temperature and atmospheric pressure influence little.It is recommended to use the instruments of higher accuracy.On the other hand,the static pressure gauge and relative hygrometer can meet the basic requirement for their insensitivity to the uncertainty of measurement results.

Analyses of channel regulation of the Dongping Waterway and effects of sand-borrow on riverbed

Hydro-Science and Engineering (2003)

Lei Ya-ping

The Dongping Waterway with a wide and shallow riverbed is dominated by fluvial and tidal currents. According to its features, regulation works with two regulating stages were carried out with satisfactory effects. Based on the analysis of the relationship between the fluvial process and regulation works and sand-borrow on riverbed, it can be seen that the regulation works and heavy sand-borrow have made combined effects of regulation and dredging, and that the sand-borrow activity should be reasonably managed and adjusted.
