Definitions

  • the invention relates to a chemical heat pump that is heated by heat, i.e. is driven by thermal energy, for pumping anergy from a room of reference temperature into a room of higher temperature according to the preamble of claim 1.
  • the annual consumption figure ⁇ defined as the ratio of exergy supplied to total thermal energy given off this corresponds to the Carnot factor of the heating task averaged over the heating period.
  • the relationship also applies if the ratio of stored exergy E to the heat generated by pumps (E + A) is referred to as the annual consumption figure cp.
  • ⁇ has values for one location of the heat pump in the climate region of Central Europe around 0.07; Due to the unavoidable losses of exergy, the values of the annual consumption figure that can actually be achieved are between 0.25 and 0.7.
  • the prior art for heat pumps with storage are characterized by zeolite storage heat pumps.
  • Zeolites are solids that can absorb water vapor while releasing energy. Zeolites can therefore be used as sorbents when water is used as the refrigerant; absorption and desorption of the two reactants in the strict sense are not a chemical reaction but rather a physical adsorption process.
  • the zeolite heat pumps are nevertheless mentioned because chemical heat pumps with chemical storage have not been described so far. (Chemical heat pumps without storage are not quite correctly called absorption heat pumps, because they are also used for desorption processes. In the conventional heat pumps, it is not water, but NH 3, for example, that is the refrigerant, which is why they are eliminated compared to the invention.)
  • Zeolite storage heat pumps pose a number of fundamental problems due to the fact that the sorbent is a solid.
  • the heat transfer to the water-saturated zeolite, for example via heat exchangers, requires a large number of surfaces and reliable contact with the solid; Because of the low partial pressure of the refrigerant water, the entire desorption process must be carried out in a fine vacuum. Since the zeolite can only be poured to a limited extent, the distinction between desorber and storage (as well as between absorber and storage) becomes obsolete: the storage itself with the zeolite supply is both absorber and desorber.
  • the invention has for its object to enable the storage of the exergy of the thermal drive energy for the heat pump over a longer period of time, sufficient for one season, chemically inexpensively, with minimal technical effort and minimal exergy requirement for auxiliary units, which should be pointed out da8 desorption and absorption can also run in parallel with different outputs if required.
  • the advantage of solving this problem is when a simple and inexpensive liquid with extremely low vapor pressure at ambient temperature and water as the refrigerant is used as the sorbent, for example air as a heat transfer medium and water vapor transport means for both desorption and absorption can, the free reaction enthalpy should be high in the reaction of sorbent and refrigerant.
  • this eliminates in particular with aggressive sorbents such as. e.g. Sulfuric acid is in direct contact with the heat exchanger, since, for example, the drive heat is supplied to the air and the heat is extracted from the air.
  • the desorption can be carried out at a relatively low temperature at ambient pressure, since the partial pressure of the water vapor loading is now almost independent of the absolute pressure in the desorber.
