Solar collectors and adsorption materials aspects of cooling system

The selection of solar collector and adsorbent-adsorbate materials are crucial to improve the solar cooling system. Different type of solar collectors are integrated with different sorption chillers. Traditional flat plate, evacuated tube and high efficient parabolic trough collector can provide temperature of 60-80 °C, 80-150 °C and 150-400 °C respectively. Solar collector selection and optimization is of paramount options in adsorption refrigeration system. Different adsorbents have different equilibrium reaction pressure, which is related to different refrigeration performance. Several studies were discussed about selection and optimization of adsorbent-adsorbate materials both theoretically and experimentally. Some of them focused on cost effective materials and improving efficiency of the systems. The current investigation summarize an overview of traditional and emerging collector technology, sorption materials as well as state-of-the-art developments.
