A novel solar adsorption refrigeration system is established and experimented by using a bed of evacuated glass tube. Towards the application in air conditioning the system has adopted ZSM-5 zeolite and water as the work-ing pair of the adsorption. With the close relation to the solar radiation intensity, the temperature of the bed reached 130℃ during the experiment. The distribution of the temperature in the bed was detected variable drastically along the tube axis, while the variation was much less along the circumferential direction. From the refrigerant inlet of the bed to the bottom the adsorption process put forwards step by step and there was a time delay. The bed temperature impacted the adsorption seriously. The COP of the adsorption system was revealed to be in between 0. 02 to 0. 05.
