Full Description
This book describes how a parabolic trough solar collector (PTSC) is capable of regenerating rotary desiccant wheel very easily in the pursuit of reducing indoor air pollution. It stresses experimentation on composite rotary desiccant wheels to dehumidify and regenerate. In this volume, regeneration rate and adsorption rate of rotary desiccant wheel for generating dry air is evaluated experimentally. An experimental study on PTSC for checking regeneration feasibility of silica gel rotary desiccant wheel and composite rotary desiccant wheels (90% silica gel-10% molecular sieves, 90% silica gel-10% LiCl and 80% silica gel-10% LiCl-10% molecular sieves) is performed. The adsorption and the regeneration rates at various air flow rate, various rotational speed of rotary desiccant wheel, in parallel flow arrangement and counter flow arrangement, at same and different sector angle of process and regeneration sides are verified. Various combinations of regeneration/process (R/P) ratios for the silica gel rotary desiccant wheel and composite rotary desiccant wheel, as well as wheel effectiveness for adsorption sector and for regeneration sector, are also studied. Ultimately, experimental results of silica gel rotary desiccant wheel are validated with the help of simulation results. The experimental results and simulation results of silica gel rotary desiccant wheel were analyzed and compared for different wheel speed, counter flow arrangement, same and different sector angle and different R/P ratio. From comparison of simulation and experimental results of silica gel rotary desiccant wheel at various parameters like process air inlet and outlet temperature, process air inlet and outlet humidity ratio, regeneration air inlet and outlet temperature, humidity ratio of regeneration air at inlet and outlet, it has been observed that there is good match between experimental and simulation results. The volume includes of the following sub-sections:-Potential biodegradable materials for binder and binder-based materials,
-Effect of biodegradable materials on fresh and hydration of construction materials,
-Strength gain in hardened formaldehyde-free binder based materials containing biodegradable binder,
-Durability of formaldehyde-free binder based materials,
-Inner-structure analysis of formaldehyde-free binder based materials.
