Metal hydride heat pumps.

Author(s) : DACOSTA D. H.


The paper describes metal hydride cold-production principles. The combination of the powder of some metals and hydrogen is a reversible reaction occuring with heat emission or absorption. A prototype is described, an air conditioner with a capacity of about 2.5 kilowatts, usable in road vehicles. Regeneration can be done using waste heat (for example from exhaust gas). Performances are given, indicated along with some price estimations and the areas in which the search for improvements can be directed.
