This paper presents the development of a new solar-powered adsorption cooling tube. It uses zeolite13X-water as a working pair. The operating principle of this solar-powered adsorption cooling tube, which consists of four major components: solar collector, adsorbent bed, condenser, and evaporator, all in one glass tube, is also presented. The experimental investigations of three generations of the solar-powered adsorption cooling tube were carried out to evaluate the system coefficients of performance (COPsys). The experimental results show that the COPsys values were 0.094, 0.161, and 0.182 for the first, second, and third generations of the solar-powered adsorption cooling tube, respectively.
