THE TEST TO AIR DISTRIBUTION PERFORMANCE IN BIG MARKETS

摘要

The objectives of this study were to evaluate the air distribution in big markets with floor area varying from 3890 to 5760 m2 based on measured data and to analyze the effect of some factors in air distribution. The tests for temperature, air velocity and humidity in the air conditioning environment in three big markets in Wuhan, China were made. The standard deviation of temperature and air velocity and ADPI were calculated. Correlation of the variables with the macroscopic numbers describing air distribution including the mean velocity, temperature difference between the mean inlet temperature and the mean temperature in the occupied spaces and the difference between the maximum value and minimum value in the story were obtained. It was found that there is a serious uneven temperature and air speed distribution in big markets.
