HEATING AND COOLING SYSTEM USING HYDROGEN STORAGE ALLOY

摘要

PURPOSE: A heating and cooling system using hydrogen storage alloy is provided to prevent foreign matters flowing along flowing path of hydrogen from flowing into the hydrogen storage alloy charged in reactors and deteriorating performance of the hydrogen storage alloy. CONSTITUTION: A heating and cooling system includes a first reactor(110) and a second reactor(120) charged with hydrogen storage alloy; a hydrogen channel tube(200) connected with the first reactor and the second reactor, respectively; a pumping unit(300) connected to the hydrogen channel tube to forcibly feed hydrogen from one of the first reactor and the second reactor to the other; and a first foreign matter resolving unit(410) and a second foreign matter resolving unit(420) installed on a path through which hydrogen flows. The first foreign matter resolving unit is installed between the first reactor and the pumping unit, and the second foreign matter resolving unit is installed between the second reactor and the pumping unit. The first foreign matter resolving unit and the second foreign matter resolving unit are formed with metal meshes coated with Ti0_2 photocatalyst.
