  • Patent number: 6634183
    Abstract: In a chemical heat pump a substance is used which within the temperature range for which the heat pump is intended has a transition between a solid phase and a solution phase. The substance can for a solar driven chemical heat pump comprise magnesium chloride hexahdrate. In an accumulator part of the heat pump a heat exchanger (21) is provided enclosed by a net (23). The solid phase is primary located inside the net in contact with the heat exchanger while the solution phase flow out of the net and is collected in space (24′) below the heat exchanger. From this space the solution phase is pumped and sprayed over the heat exchanger from a spray bar (25). Thereby, all the time equilibrium is maintained. The advantage including the constant temperature step and the relatively large energy content of solid substance is thereby combined with the high power of liquid substances.

  • Publication number: 20020017380
    Abstract: In a chemical heat pump a substance is used which in an efficient way interacts with a volatile liquid such as water. The substance is selected considering among other things the magnitude of its &Dgr;T and its energy content so that the heat pump becomes suited for converting low grade heat energy such as solar energy to cooling for airconditioning and also for a simultaneous production of heat for example for use as hot tap water in houses. The heat pump can also be used in a refrigerating box. Suitable substances comprise barium hydroxide, lithium hydroxide, strontium bromide and cobalt chloride. The substance is applied as a layer (23) on the surface of a heat conducting wall (22) by applying a slurry-like mixture of the substance with the liquid when being vibrated to the wall between heat conducting flanges 25). The mixture is dried under a vacuum and is heated and is simultaneously compressed by applying an exterior pressing force.
