摘要
将能够同时制冷和制热的太阳能吸附制冷管组装成单元,再将8组单元组成一个太阳能空调系统,利用该太阳能空调系统与一个坡型屋顶办公建筑结合,通过该太阳能空调系统向房间提供冷量和生活热水。对该太阳能空调与住宅建筑的能量耦合进行试验研究,得到以下结论:在太阳能辐射量为21～23MJ·m^(-2)之间时,该太阳能空调系统可以向房间提供冷量约27MJ,最大送回风温差约为7℃,最大制冷功率约为1.1kW,同时该系统还可以向房间提供45℃热水约450kg,整体系统的COP约为0.15。该太阳能空调系统与建筑结合减少空调电力消耗约3kWh/d,减少热水耗用标准煤2.7kg/d,可以降低建筑对电力的消耗和依赖,实现构造绿色节能建筑的理念。
The solar collector was made up of 20 solar cooling tubes which can supply thermal and cooling mass in one tube. There were 8 such solar collectors on the slope roof in this system integrated with an office building. The solar air-conditioning system could reduce the electrical consume and construct a green building. The experiment results show that the solar air-conditioning system can supply cooling mass by 27MJ when the solar radiation intensity is about 21-23MJ·m^-2, the maxmium temperature difference between outlet and inlet is about 7℃, the maxmum power for the solar air-conditioning system is about 1. lkW. At the same time, the system can supply 450kg 45℃ hot water and its COP is about 0.15. The solar system can save 3kWh electricity and 2.7kg coal each day, and realizes sustainable green building.
