中文摘要：

采用热排空法进行了复合吸附剂吸附脱附性能测试试验．该方法在不使用真空泵的情况下将空气排出，使得系统内空气分压力小于2Pa，符合国家标准对测试试验的要求．通过测定13X沸石原粉和整体成型复合吸附剂的吸附脱附性能得出：其测试值与文献值偏差小于8％，脱附过程和吸附过程中吸附床温度变化速率较高，分别为6．7℃／min和～13．7℃／min；对各个复合吸附剂性能的测试和比对得到复合吸附剂E，其脱附性能较好，将复合吸附剂E应用于太阳能冷管中的制冷系数COP约为0．24～0．28．

英文摘要：

The thermal vacuum method was used to test the adsorption performance of compound adsorbent. This thermal vacuum method, without vacuum pump, can expel the air of system up to its partial pressure, lower than 2 Pa, so it can meet the demands of the test. The adsorption performance of 13X zeolite and some compound adsorbent were tested and the following conclusions can be drawn, the adsorption capacity measured by this way has the less difference （〈8%） with the reference. In this experimental system, the adsorbent bed＇s temperature rising rate of desorption and adsorption process is about 6.7 ℃/min and --13.7℃/min respectively. With these tests, the compound adsorbent E, which has better adsorption performance, is used in a solar cooling tube system as adsorbent and the experimental coefficient of performance （COP） of the solar cooling tube can reach 0.24-0.28.
