The design, performance, and cost of a solar-powered metal hydride heat pump and power system for use on a residence are presented. This system was first conceived of and its feasibility demonstrated by Dieter Gruen, et al, at Argonne National Laboratory. The system design, which is limited by heat transfer, was optimized via an iterative computer program. The design process starts with optimizing the thermal transport properties of the hydride-bed-heat exchanger, then traces temperatures and pressures through the operating cycles. The coefficient of performance (COP) of the overall system is then determined from the thermal losses due to cycling the hydride beds and due to the auxiliary power consumed by freon pumps and air-moving fans. The system, using high temperature solar collector input at 210/sup 0/F to 280/sup 0/F, provides heating with a COP of approximately 1.6 and cooling with a COP of approximately 0.6, and electrical power during spring and fall, all for a cost comparable to a solar absorption cooler.
