【摘要】 在地板送风实验室内建立了温度场测量系统,并对其进行了标定。通过对地板送风几种典型工况的实验, 结果显示水平方向上风口区以外的温度分布变化小,垂直方向上存在着类似于置换通风的温度梯度,并由实验数据分析得到送风温度和送风量对垂直温度梯度影响的程度。更多还原

【Abstract】 The temperature measuring system in the full - scale test room by underfloor air supply was set up. The Type T thermocouples were calibrated. The results of some typical experimental cases of underfloor air supply showed that the temperature distribution was symmetrical at level except the air discharge diffuser zone, and stratified at vertical just like displacement ventilation. Furthermore, tests were conducted to investigate the effects of supply air temperature and air supply volume on the vertical temperature gradient.更多还原
