随着城市的发展和人类工业活动的增加,人类的热环境正在悄悄地起着变化.城市中急剧增加的人口,每时每刻都在向大气中散发着热量;人类的生产和生活都要消耗能源,这些能源所释放出的能量除一部分被人们利用外,其余的都将转化为热散发到空气中,如锅炉、电动机、空调、电冰箱、汽车等在工作中都在消耗能量并向外放热;城市建设中大量使用混凝土和沥青,改变了地表的反射率和蓄热能力.所以,人类的活动时刻都在影响着环境的温度.
With the development of the city and the increase of human industrial activity, the human thermal environment is quietly changing. The rapidly increasing population in the city is radiating heat to the atmosphere every moment; human production and life are Consuming energy, the energy released by these energy sources will be transformed into heat and released into the air, in addition to being used by people. For example, boilers, electric motors, air conditioners, refrigerators, and automobiles all consume energy in their work. Exothermal heat; the use of concrete and asphalt in urban construction has changed the reflectivity and heat storage capacity of the earth’s surface. Therefore, human activities affect the temperature of the environment at all times.
