A theoretical thermal model for a heat pump module using evacuated tube solar adsorption
In collaboration with Dr. Phelan, a recent study delves into the innovative design of a solar adsorption cooling module, blending an adsorption heat pump with an evacuated glass tube solar collector. This sophisticated module, outlined in a theoretical framework based on solid experimental data, features a division of an adsorbent bed and an evaporator/condenser within a single evacuated glass tube.
The analysis indicates optimal design points for key components to maximize energy efficiency. Zeolite 13X and silica gel type-RD are identified as effective adsorbents, with the thermodynamic assessment yielding a solar coefficient of performance (COP) of 0.11 and 0.2, respectively.
Curbing concrete’s carbon emissions with innovations in cement manufacturing
Discover how Arizona State University’s innovative research is revolutionizing the cement and concrete industry, a major source of CO2 emissions. With the National Science Foundation’s support, ASU experts are developing methods to reduce the carbon footprint of cement manufacturing. As concrete ranks as the world’s second most used material, ASU’s work is critical in addressing global environmental challenges. Their groundbreaking approaches aim to decrease CO2 emissions from limestone processing, a key step in cement production. Join ASU in their journey to transform one of the largest contributors to global carbon emissions and foster eco-friendly infrastructure.
