Abstract : This invention relates to a cycle for a heat driven heat pump using two salts CaC12.8NH3 and ZnC12.4NH3 which may reversibly react with ammonia with the addition or evolution of heat. These salts were chosen so that both ammoniation processes occur at the same temperature so that the heat evolved may be used for comfort heating. The heat to drive system need only be slightly hotter than 122 C. The low temperature source need only be slightly warmer than 0 C.
