渡口位于金沙江河谷区,纬度较低,海拔较高,属于亚热带干热河谷气候,常年云雨不多,气温较高,无霜冻期,日照充沛,太阳辐射较强。根据渡口气象资料查证,日照时数全年变化于2600～2800小时,日照百分率为63%左右,太阳辐射强度为150.5千卡/cm~2年,有利于太阳能利用。为了发挥这一气候特点,渡口市科委给我们下达了“室外平板太阳能集热器热性能测试装置研制”课题。现已建成投入运转,效果良好,达到了预期目的,见图1。
The ferry is located in the Jinsha River Valley, with low latitude and high altitude. It belongs to the subtropical dry-hot valley climate. It has few clouds and rain, high temperatures, no frost, abundant sunshine, and strong solar radiation. According to the verification of ferry weather data, the number of sunshine hours varies from 2600 to 2800 hours throughout the year, the percentage of sunshine is about 63%, and the solar radiation intensity is 150.5 kcal/cm~2 years, which is favorable for solar energy utilization. In order to take advantage of this climate feature, the Science and Technology Committee of Dukou City gave us the topic of “Development of Test Equipment for Thermal Performance of Outdoor Flat Panel Solar Collectors”. It has been completed and put into operation with good results and achieved the intended purpose. See Figure 1.
