摘要(Abstract):

以西安市作为研究地点,利用太阳能发电驱动以干空气能作为驱动势的蒸发冷却空调进行应用研究。通过试验得出,500W光伏系统,年发电量约456.25k W·h,可节约标煤164.25kg,减少碳排放454.88kg。8月测试日室外温度34.3~39.6℃时,空调机组的二次风排风温度为29.1~30.7℃,温差5.2~8.9℃,可利用这部分冷量给光伏板降温、除尘,以提高发电量。经优化方案,分布式系统综合效益可观、应用前景广阔。文章并对西北地区资源情况进行初步评估。
Taking the city of xi 'an for example,application research on using the solar power to drive evaporative air conditioning which uses the dry air energy as driving force. Through the experiment,500 W photovoltaic( PV) system,outputs about456. 25 k W·h,annually saves standard coal about 164. 25 kg and reduces carbon emissions of 454. 88 kg. When outdoor temperature is 34. 3 ~ 34. 3 ℃,the secondary air exhaust temperature of the air conditioning unit is 29. 1 ~ 30. 7 ℃,the temperature drop about 5. 2 ~ 8. 9 ℃,on a testing day in August. In order to improve the capacity of,we can use the energy to cool the PV panel and remove dust. After optimization,grid- connected power generation system has considerable comprehensive benefits,and application prospect. The paper also carries on the preliminary assessment of resources situation in northwest.
