    摘要:

    人體舒適度對人們的工作和生活具有重大的影響,研究不同天氣條件下的人體舒適度對公共氣象服務具有更重大的意義。在成都信息工程學院4種典型的空間,利用大氣探測技術和手段,獲得2013年6月至2014年3月每天3個時次(07:00、13:30、19:00)的氣溫和濕度資料。應用溫濕指數(THI)分析了典型陰天和晴天情況下,室內外人體舒適度差異,并對兩者的相關性進行研究。研究結果表明:①在晴天,人流較多的小型室內舒適天數最多,占總天數的61%;在陰天,室外舒適天數最少,占總天數的40%;②不同天氣舒適度區別最大的季節為夏季,晴天,人流較少的小型室內舒適度最好,室外舒適度最差;而陰天,室外舒適度最好,人流較多的小型室內舒適度最差;③陰天人流較少的小型室內與室外溫濕指數達到顯著相關,且相關性最好(〖WTBX〗R〖WTBZ〗2=0.97),而人流較多的大型室內與室外溫濕指數的相關性最差(〖WTBX〗R〖WTBZ〗2=0.92)。

    Abstract:

    Human comfort has a significant impact on people’s work and life, and studies of human comfort under different weather conditions are important in public meteorological service. Using the atmospheric detection technology and means, the temperature and humidity were obtained at three times (07:00,13:30,19:00) a day in four typical observation sites in the Chengdu University of Information Technology from June 2013 to March 2014. The difference of indoor and outdoor human comfort is analyzed under typical cloudy and clear days, and the correlation of indoor and outdoor human comfort is studied by using the temperature and humidity index (THI). The results show: (1) On sunny days, the number of comfortable days is the greatest in the crowded indoor environment, accounting for 61% of the total number of days; on cloudy days, the number of comfortable days is the least in the outdoor environment, constituting 40% of the total number of days. (2) The biggest difference in human comfort under different weather conditions is in summer. On sunny days, the human comfort in small rooms with less people is the best, while outdoor comfort is the worst. However, on cloudy days, outdoor comfort is the best, while the human comfort in big crowded rooms is the worst. (3) On cloudy days, a significant correlation is found in temperature and humidity indexes between less crowded small indoor and outdoor environment, the correlation being the best (〖WTBX〗R2 〖WTBZ〗=0.97), while the correlation is the worst (〖WTBX〗R〖WTBZ〗2=0.92) between large crowded indoor and outdoor temperature and the humidity indexes.
