Abstract

Heating and cooling systems based on hydrogen sorption in metallic alloys have attracted researchers due to their advantages such as environmental friendliness, ability to utilize low-grade waste or renewable energy, wide operating temperature ranges, and availability of a plethora of alloys to choose from. These heat-operated systems offer a viable alternative to conventional electrically driven HVAC systems. In this paper, a metal hydride-based heating and cooling system (MHHCS) which can cater to the year-round comfort air-conditioning of locations with extreme climatic conditions is proposed. The paper describes the cyclic operation of the MHHCS for application in buildings through the different seasons of a year. The performance of the system is studied using a matched alloy pair of Zr0.82Mm0.09Ti0.09Fe1.4Cr0.6 � LaNi4.6Al0.4 chosen based on thermodynamics and reaction kinetics. This paper discusses the effects of system parameters and operating conditions on the year-round performance of the MHHCS. © 2021 Elsevier B.V.
