空气相对湿度是与人们生活、生产密切相关的重要环境参数之一。室内湿度过低或过高，会引起室内人员不适，空气相对湿度是衡量室内环境的一项重要参数，对人体健康、室内空气质量以及物品的存放都有重要意义。国家空气质量标准规定室内相对湿度标准值，夏季空调房间为40％～60％，冬季采暖房间为30％～60％。加拿大学者Anthony V.Arundel等综合了各种因素,考虑湿度对微生物生长、人体发病以及物品变质等各种影响后，推荐最佳的相对湿度范围在40％～60％之间。The relative humidity of the air is one of the important environmental parameters closely related to people's life and production. If indoor humidity is too low or too high, it will cause discomfort to indoor personnel. Relative air humidity is an important parameter to measure the indoor environment, which is of great significance to human health, indoor air quality and storage of items. The national air quality standard stipulates the standard value of indoor relative humidity, which is 40%-60% in air-conditioned rooms in summer and 30%-60% in heated rooms in winter. Canadian scholar Anthony V. Arundel and others integrated various factors, and after considering the various effects of humidity on microbial growth, human disease, and deterioration of goods, the best relative humidity range is recommended to be between 40% and 60%.
