摘要
It is important to analyze the indoor temperature field for Gravity air-conditioning, which is a new technology. This paper investigates the vertical and horizontal temperature distribution by experiment. The result shows that in working area, the maximum temperature gradient is about 3 虋Cand PD is less than 4%, which can meet the thermal comfort requirement. The temperature in working area is in the range of 23 虋C鈭?8 虋C in the experiment, which can meet the cooling requirement. The indoor temperature field presents uniform temperature distribution in the horizontal level and layered distribution in the vertical direction, which is consistent with the normal distribution of displacement ventilation.
