Adsorption Performance of Compound Adsorbent Using the Thermal Vacuum Method
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. the adsorption performance of 13X zeolite and some compound adsorbent were tested by this way. Conclusions can be drawn as following: the adsorption capacity of 13X measured by this way has the less difference (<10%) with the reference. In this experimental system, the compound adsorbent, which has better adsorption performance and mould performance, was used in a solar cooling tube system as adsorbent and the experimental coefficient of performance (COP) of the solar cooling tube can reach about 0.26.
