Abstract

A process for cooling a passenger compartment of a vehicle equipped with a hydrogen-consuming engine by mechanical refrigeration involves compressing a gaseous coolant, condensing the resulting compressed and heated gaseous coolant with heat removal to liquefy the coolant, and evaporating the liquefied coolant under the action of a pressure relief valve so that the cold generated during the pressure relief is used to cool the passenger compartment. This process is improved by removing additional heat from the compressed coolant by passing the coolant through a metal hydride cooler.
