Definitions

  • the present invention relates to improvements in a heating installation equipped with an absorption heat pump.
  • an absorption heat pump is sometimes used in order to improve the thermal efficiency of the heating.
  • the burner is used to boil the absorption solution used in the absorption cycle of the heat pump so as to separate the constituents of the solution and regenerate the absorption fluid used in the cycle.
  • the yield is poor because, taking into account the conditions of the heat exchange, the smoke leaves the installation at a generally high temperature above 200 ° C. à The chimney large amounts of energy that are lost.
  • the heat pump boiler exchanger comprises two stages arranged in series, the first forming a boiler serving to bring the absorption solution to the appropriate temperature, the second forming a recuperator serving to heat the fluid of heating in the vicinity of its entry into the installation.

  • a first exchanger for a heat pump boiler and a second recuperator exchanger placed in series with the first and serving to heat said fluid said first exchanger communicating with a separator in which the separation of the "distillate” and the "residue” takes place.
  • said burner comprises a combustion chamber in contact with which is placed a liner which communicates directly with the part of a separation column forming the aforementioned separator, said column being placed just above and into which are introduced the returns of the absorption solution to be regenerated.
  • the operating conditions of the installation are considerably improved as this not only improves heat recovery at the burner and for the benefit of the installation, but also increases the temperature of the absorption solution to be regenerated and simultaneously improve the efficiency of the separation, therefore the thermal efficiency of the absorption cycle.
  • said lining is divided into two adjoining chambers, the first in which said returns of the solution to be regenerated are admitted, before being introduced into said separation column, the second which communicates directly with the solution present at the base of said column by at least one large opening favoring heat exchanges by thermosyphon, such a construction design, of simple technique naturally and automatically ensuring excellent homogeneous heating of the absorption solution to regenerate directly at the base of the separation column.
  • FIG. 1 illustrating the overall diagram of an installation designed according to the invention.
  • the installation essentially comprises the cycle of the absorption pump comprising the boiler-regenerator 1, the condenser 2, the holder 3, the evaporator 4, the absorber 5, a circulation pump 6 for the solution, a heat exchanger 7 and an additional exchanger 8.
  • the regenerative boiler 1 consists essentially of a burner with its combustion chamber 9 comprising two respective heat exchangers in succession. ment 10 and 11 constituted by two twin tubes mounted in series, the inner tube 12 common to the two exchangers being traversed by the fumes produced in the combustion chamber 9 and which escape at 13 to the chimney (not shown).
  • the regenerative boiler 1 further comprises a separation column 14 which receives after their heating, in particular in the heat exchanger 10 and at the level of the part 20 of the lining 15 surrounding the combustion chamber 9, returns of the solution to be regenerated from the absorber 5.
  • the regenerating boiler 1 also comprises a so-called de-phlegmator apparatus 16 which receives the distillates produced at the head of the separation column 14 with a view to their drying in order to improve the efficiency of the absorption cycle.
  • FIGS. 2, 3 and 4 The installation being thus described in its entirety, reference will now be made to FIGS. 2, 3 and 4 with the help of which some specific apparatus used in the installation will be described in more detail.
  • the burner (not shown), the flame of which has only been shown diagrammatically 16 comprises a combustion chamber 17 surrounded by a liner 15.
  • the liner 15 is divided by a partition 18 into two chambers respectively 19 and 20.
  • the chamber 19 is in communication by two relatively large cross-sections 21, 22 with the base of the column 14. In this way it is established under the effect of the heating which takes place in the combustion chamber 17 efficient circulation in thermosyphon of the solution to be regenerated present up to the level marked 23 in column 14. This gives good homogenization of the temperature of the solution to be regenerated in column 14.
  • the conduit 24 opens through its upper orifice 25 at substantially mid-height of the column 14, which comprises a number of baffles 26, 27, 28 forming simplified distillation plates in this column.
  • the column 14 comprises a number of baffles 26, 27, 28 forming simplified distillation plates in this column.
  • the liquid residue leaves the separation column through line 29 at the base of the column, while the distillate leaves at the top of the column through line 30.
  • the distillates leaving the column 14 through the conduit 30 enter the deflegmator 16 at the upper part of a volume 31 formed between the vertical circular cylindrical wall 32 of the dephlegmator 16, and a more internal concentric wall 33.
  • A.1 'inside the volume 31 is also arranged a tubular helix 34 in which circulates as indicated by the arrows the fluid to be heated forming a refrigerant entering the de-phlegmator through the conduit 35 and leaving through the conduit 36 which forms the start heating of the installation.
  • the distillates introduced at 30 into the de-phlegmator are therefore channeled along a peripheral helical path descending against the current with the fluid to be heated traversing the propeller 34 and unblock towards the base of the apparatus in the volume marked 37.
  • the distillates are thus subjected to both a centrifugation effect and a refrigeration effect which tend to condense the parts of residue entrained with. distillates and to separate them from lighter distillates.
  • the condensed residues escape from the de-phlegmator through the conduit 38 located at the base of the apparatus while the distillates in gaseous form escape from the apparatus through the conduit 39, the outlet of which is placed at 40 in upper part of the appliance.
  • the separation column 14, the de-phlegmator 16, the heat exchangers 7 and 8 have all been housed inside the two twin-tube propellers constituting the heat exchanger 10 for the heat pump boiler and the heat exchanger 11 forming a heat recovery unit for the fluid to be heated.
  • the heat exchanges in the installation are improved, all the "hot" exchangers being placed inside the two hot exchangers 10, 11.
  • the absorber 5 and the condenser 2 find their place outside the exchangers 10, 11, the entire installation, excluding the evaporator 4, which can thus be housed in an envelope forming an external covering (not represented)
  • FIGS. 1 and 5 the operation of the installation and the various circulation circuits will be described.
  • the distillates are produced as mentioned above in the separation column 14 from the absorption solution coming from the absorption column 5.
  • the distillates escape at the top of the column 14 through the conduit 30 entering the de-phlegmator 16.
  • the distillates rid of their "humidity" (the heavy parts of "residue” entrained being returned to column 14 through the conduit 38) are brought by the conduit 39 inside the condenser 2 cooled against the current by the fluid circuit to be heated in which the condensation takes place.
  • the condensed distillates are then admitted via line 41 into the pressure reducer 3 in which their expansion and subsequent cooling takes place.
  • the evaporator 4 which can be an air exchanger exchanging heat with the ambient medium or for example water exchanging heat with waste water. It is at this device, as it is known that the heat is borrowed from the outside environment.
  • the distilled distilled thus warmed at the outlet of the evaporator 4 penetrate by the conduit 43 at the top of the absorption column 5. In this column, the distillates are absorbed by the heavy residues brought by the conduit 44 into the absorber and to which they mix, releasing heat, which is partly exchanged with the fluid to be heated as will be described below in relation to this circuit.
  • the mixing solution leaves the absorber via the conduit 45 from where it is taken up by the pump 6 to be brought back after crossing the heat exchanger 7 in counter current with the hot residues coming from the column 14, before entering in the exchanger 10 then the chamber 20 formed around the combustion chamber 17 before being introduced into the separation column 14 through the conduit 24.
  • the cold inlet due to the fluid to be heated which can constitute, for example, the cold returns of a central heating takes place at 48 at the end of the exchanger 11 by which the fumes 13 from the installation are evacuated.
  • the evacuation of condensates from the fumes the temperature of the cold returns generally making it possible to recover at least a large part of the heat of condensation of the fumes.
