地下工程既具有冬暖夏凉、适当开阔空间可供开发利用的优点,也有在夏季凝露极为潮湿的弊病。通风空调虽可消除地下建筑的结露并降低潮湿,但进一步判断通风换气的效果,则有赖于对空气质量的评价,以便创造适宜的舒适环境,有利于人们坚持地下生活和工作,并为开发地下空间用作第三产业的可行性提供依据。一、方法和指标(一)方法 Underground engineering has both winter and summer cool, suitable for the development of open space advantages, but also in the summer condensation extremely damp ills. Although ventilation and air conditioning can eliminate the condensation of underground buildings and reduce the humidity, further judgment on the effectiveness of ventilation depends on the evaluation of air quality in order to create a comfortable environment conducive to people’s subsistence and work life Provide a basis for the feasibility of developing underground space for use as a tertiary industry. First, methods and indicators (a) method
