An air changeover system (100) for a metal hydride heat pump is disclosed. The system (100) includes metal hydride reactor modules (102, 104) aligned and separated by a partition (118); a shell containing the reactor modules (102, 104), the shell is compartmentalized to define separate insulated chambers for each of the reactor modules (102 & 104); and a bearing assembly (110) supporting the modules (102, 104) at a location about the partition (118), wherein the bearing assembly (110) rotates said modules (102, 104) about an axis during the absorption and the desorption mode. The system (100) reduces thermal inertia and pressure drop in the heat transfer medium while flowing through the heat pump, to enhance the performance and conserve energy.
