摘要
夏季太阳能辐射强度与空调负荷有很好的一致性,这使得太阳能辅助空调具有独特的优点。根据郑州地区夏季太阳辐射和空调负荷特点,针对某一太阳能辅助吸收式空调系统进行了理论分析,该系统供冷对象为200m2别墅,采用60m2平板式太阳能集热器和一个带有辅助加热装置的集热水箱作为热源。在发生器温度为70—100℃,蒸发温度5—15℃的范围内计算了系统性能系数和太阳能利用率。计算结果表明,在5—9月份,太阳能可以提供建筑冷负荷的76—122%。
The synchronizing of cooling loads with solar radiation intensity is a particular advantage when solar energy is used in cooling or air conditioning in residential buildings. Combined with the characters of cooling loads and solar radiation in summer in Zhengzhou, the theoretical behavior of thermal parameters and interaction in absorption cooling systems powered with solar energy is investigated. A flat plate solar collector and a thermal storage tank with auxiliary heaters are adopted in this system, and a computer program is developed to calculate the COP and useful solar energy with the generator temperature from 70 to 100℃ and the evaporation temperature from 5 to 15℃. The results indicate that solar energy can provide 76 to 122% cooling load for the villa with 200m^2 in Zhengzhou.
