【Abstract】 The research and advancement on the structure and performance of a solar cooling tube were presented. Evacuated solar collector and selective coatings are used to enhance the solar absorptivity and decrease the heat dissipation. Solidified composite adsorption block is used to improve the adsorption capacity and the heat conduction of the adsorbent bed. The experimental investigation of desorption dynamics of the tube indicates the improvement of vacuum in affecting desorption rate. A model refrigerator of the solar cooling tube was also described. Consequently a new kind of multifunction solar cooling tube, which is designed to supply both heating and cooling simultaneously, was tested. Its cooling coefficient is about 0.193 and the whole performance coefficient of heating and cooling is about 0.692.更多还原
