中文摘要：

利用太阳能冷管作为制冷制热单元，并将该冷管单元应用于现有的大空间空调系统。在夏季晴好的天气状况下，该冷管系统可以提供260MJ／d冷量，满足部分的大空间建筑在夏季冷量需要，同时该系统每天可向大空间建筑内提供7000kg，47℃生活热水。利用太阳能光伏系统提供部分电力，可以为30支20W节能照明灯具提供连续2个夜晚的照明用电。冷管系统和光伏系统可以每日节省空调用电、电加热用电以及照明用电约230kW·h，同时建立示范性太阳能绿色，节能建筑。

英文摘要：

The solar cooling tube can serve with heat and cool loads alternatively and the solar energy hybrid system for the large space atrium air-conditioning system is introduced. On sunny days of summer, the solar energy hybrid system can supply cooling about 260MJ/d, decreasing part of electrical consumption of the system. Meanwhile, it can supply hot water of 7000kg in 47℃. The solar photovohaic system can generate electric power which can supply about 30 lamps of 20 Watt each for 2 nights. The two systems can save about 230kW·h. The solar energy collectors on the roof can also decrease the air condition load of the large space atrium. The building can be an energy saving demonstration.
