Descripción del proyecto
Nuevos fotomateriales para la gestión térmica
El objetivo del proyecto PHOTHERM, financiado con fondos europeos, es cambiar radicalmente la forma de generar calefacción y refrigeración mediante el desarrollo de una nueva clase de materiales que capturen, almacenen y liberen tanto el calor solar como el ambiental. Los materiales de gestión de la energía solar térmica incluyen fotointerruptores moleculares que capturan y almacenan la luz solar, los denominados sistemas MOST, así como materiales de cambio de fase (MCF) que contribuyen a la gestión térmica. Los sistemas MOST capturan los fotones de la luz solar y el calor ambiental, mientras que los MCF pueden absorber el calor del entorno. La combinación de MOST y MCF tiene el potencial de alterar la forma de controlar la temperatura en una amplia gama de aplicaciones, como la producción local de energía, los sistemas electrónicos, los automóviles y las viviendas.
Objetivo
Since the beginning of civilization, humanity has built houses to sustain comfortable living conditions throughout the seasons. In our modern society, about 50% of the total energy consumption is used for heating and cooling. Growing demands for thermal management in many different sectors, from electronics to housing, inevitably means increased energy consumption. The primary source of heat is coming from the combustion of fossil, bio, or waste-based feedstocks, all contributing to emissions. This project seeks to fundamentally change how we generate heating and cooling by developing a new class of materials that capture, store, and release both solar and ambient heat. The solar thermal management materials are a unique combination of molecular photo-switches that capture and store sunlight, so-called MOST systems, together with phase change materials (PCM) that can contribute to thermal management. The two classes of materials operate at fundamentally different principles. The input of MOST system is photons, whereas the output is heat. The PCM materials can absorb heat from the environment. By combining the two materials into one, we can harness and upgrade two of the most abundant renewable sources of energy on the planet: ambient heat and sunlight. The materials function will be demonstrated in heat to power devices that can operate 24/7 without the need for traditional batteries. The MOST-PCM combination has the potential to disrupt how we control the temperature in a broad range of applications, from local power production to heating and cooling in electronics systems, to temperature control in automotive and housing. The materials developed in this project have the potential to radically change thermal comfort and energy consumption and give new design opportunities to thermal management systems from the 10-9 to 10 m length scale.
