昆明城市太阳辐射资源及利用现状初探

A preliminary study on the solar radiation resources and actuality in use of the Kunming City

利用有关资料,对昆明城市太阳辐射资源和利用现状进行了初步探讨。分析得知,昆明地区太阳辐射具有独特的分布特征,为太阳能的利用提供了良好的环境条件;太阳能热水器在干季晴好天气时增温效果显著。通过对不同太阳能热水器普及率和不同增温率的太阳能热水器等的计算,可以看出昆明城市太阳能热水器的节能效应是十分显著的,但仍有较大空间。加大昆明城市太阳能热水器的普及工作对于城市太阳能利用将是十分重要的。

Based on observations of data,the solar radiation resources and actuality in use of Kunming have been studied.The results indicate that distribution characteristics of solar radiation in Kunming are unique,which can provide favorable environmental conditions for the use of solar energy,and result in marked rise of temperature in the solar-energy water heater when the weather is fine in dry season.By computing different popularization rate and temperature rise rate of the solar-energy water heater,it is seen that the effect of energy-saving is marked in Kunming in despite of limitations.It is important to utilize solar energy in cities by enhancing popularization rate of solar-energy water heater in Kunming.
