Title: Solar Assisted Heat Pump Program Overview and Summary of Work at Brookhaven National Laboratory
Abstract: Four generic paths for avoiding the high utility power demand for solar-assisted heat pump systems when the sun is not shining and storage is depleted are described. These include the bimodal solar-assisted heat pump (SAHP) system, direct-expansion solar collector/heat pump systems, volume-dominated ground-coupled systems, and area-dominated ground coupled systems. Work at BNL on heat pump development, ground coupling, and low-cost collectors for use with these systems is reviewed. (WHK)
