Desiccant Heat Pump Storage • Solar heat in summer: • Evaporate water out of weak desiccant (1250 Btu/lb) • Makes strong desiccant – For cooling, and store for winter heat • Desiccant heat in winter • Condense water vapor onto strong desiccant (1250 Btu/lb) • Makes weak desiccant SEET Solar Thermal Seminar 7/26/07
