基于所设定的室内热舒适条件,通过Climate Consultant软件,利用湿度图来分析贵州省典型城市的居住建筑夏季自然通风和机械通风的有效性.研究结果表明:毕节地区采用自然通风结合适当的机械通风基本上可以取代夏季空调.贵阳和兴义地区夏季采用机械通风的有效时间比分别为85.13％和80.20％,通过设置合理的通风方式和气流组织形式,基本上可以用机械通风代替空调.遵义地区采用自然通风和机械通风的有效时间比分别为21.10％和51.60％,采用通风措施可以相对的减少遵义夏季空调的开启时间.%Based on the climate consultant software, this paper analyzes the effectiveness of natural ventilation and mechanical ventilation in summer on Guizhou residential buildings through calculating the psychometric chart. The results show that the natural ventilation combined with proper mechanical ventilation can basically replace the using of air-condition in Bijie. In Guiyang and Xingyi,the ratio of effective time using mechanical ventilation is 85. 13% and 80.20% respectively. Through establishing reasonable ventilation mode and airflow organization , the mechanical ventilation can replace basically the air-condition in summer. In Zunyi,the ratio of effective time using natural ventilation and mechanical ventilation is relatively lower, which is 21.20% and 51.60% respectively. The ventilation can reduce the open times of air-condition in Zunyi.
