Definitions

  • the invention relates to a two-substance compression heat pump or refrigeration machine with a degasser and a resorber which are connected to form a solution circuit in which a two-substance working medium, preferably formed by an ammonia / water mixture, is circulated.
  • a two-fluid compression heat pump or refrigeration machine (DE-PS 35 36 953) of this type is known, which already has a significantly improved performance figure compared to the corresponding machines working without additional degassing of the poor solution supplied to the temperature changer.
  • the invention has for its object to further increase the performance figure of the known two-fluid compression heat pump (or refrigerator).
  • this object is achieved in that in the first line branch of the solution circuit which promotes the poor solution from the degasifier to the resorber, at least two pumps which increase the pressure in the poor solution gradually to the resorber pressure are switched on and the additional degasifier in the one running between the two pumps, is arranged on an intermediate pressure section of the first line branch, and that the gaseous working fluid component additionally expelled from the poor solution in the further degasser at the level of the intermediate pressure by means of a separate compressor or by feeding into a medium pressure stage of the gaseous working fluid component from the main degasser to the resorber multi-stage compressor is promoted to the resorber.
  • the poor solution is additionally degassed by transferring heat from the rich solution and the poorer solution in the resorber is able to absorb a comparatively larger proportion of gaseous working fluid component and thus also a comparatively larger amount of absorption heat is generated.
  • the additional degassing of the poor solution at the medium pressure can either be carried out at the pressure level of the degasser instead of the additional degassing provided in the known heat pump or refrigerator, or - preferably - in addition to the degassing at the low degasser pressure level .
  • the heat pump according to the invention illustrated in FIG. 1, designated in its entirety by 10, has a degasser 12 in which, at a low pressure level PE, gaseous working fluid component is expelled from a rich two-substance working solution by supplying thermal energy at a low temperature level. If the preferred ammonia-water mixture is used as the working medium, the degasser 12 is therefore Gaseous ammonia is expelled from the solution.
  • the thermal energy of low temperature levels required for degassing the rich solution can be taken, for example, from the ambient atmosphere or from a stream. If available, waste heat from another technical work process can of course also be used.
  • the degasifier 12 is supplied with water taken from a river via a line 14 and - after the removal of thermal energy for the degassing of the rich solution - is removed again via a line 16 with a correspondingly lower temperature.
  • the resulting poor solution of the working fluid in the degasser 12 is pumped via a first line branch 18 to a resorber 20 while increasing the pressure to a pressure p R , while the gaseous working fluid component is fed to the resorber via a line 22 with the multi-stage turbo-compressor 24 switched on.
  • the heat of absorption occurring in the resorber 20 during the absorption of the gaseous working medium in the poor solution at a high temperature level can then be used, for example, to produce hot water from colder water supplied via a line 26.
  • the hot water discharged from the resorber 12 via a line 28 can then be used, for example, for heating purposes.
  • the solution, which is rich again due to absorption of the gaseous working medium, is returned from the resorber 20 via a second line branch 30 to the degasifier 12 by reducing the pressure to the pressure level PE in a throttle element 32.
  • the poor solution emerging from the degasser 12 is further degassed in a further degasser 34 connected downstream in the line branch 18 at the pressure level p E , by using the pressure flowing through the line branch 30 and still at the pressure level p R contained rich solution contained heat is transferred to the poor solution.
  • the additionally expelled gaseous working medium component, ie the additional ammonia, is fed via line 22a into the section of line 22 located in front of turbo-compressor 24.
  • two pumps 36a and 36b are provided, by means of which the pressure in the poor solution first of all from the pressure PE prevailing in the degasifier to an intermediate pressure p z and then from this intermediate pressure to the resorber pressure p Ft is increased.
  • a temperature changer 38 is connected to the sections of the two line branches 18 and 30 located at the absorber pressure p R.
  • the heat pump 10 - except for the two-stage pressure increase of the poor solution by means of two separate pumps 36a and 36b - corresponds to known two-material compression heat pumps.
  • a further degassing of the poor solution by means of heat contained in the rich solution at the pressure level of the intermediate pressure p z is provided in a further development of the known heat pumps.
  • a further degasifier 40 is switched on in the section of the poor solution line 18 which runs between the pumps 36a and 36b and the section of the rich solution line 30 which runs between the resorber 20 and the throttle element 32, in which a further degasser 40 is connected
  • a further portion of gaseous working medium component ie ammonia
  • Compressor 24 is promoted. In the section of the lines 22 connected downstream of the compressor 24 and leading to the resorber 20, a quantity of gaseous working medium composed of the sum of the partial quantities expelled in the degassers 12, 34 and 40 flows, but the drive power for the turbo-compressor 24 driving motor 42 only with respect to the partial quantities from the degassers 12 and 34 for the total pressure difference between the resorber pressure p R and the degasser pressure p E , with respect to the partial quantity expelled in the degasifier 40, however, only for the pressure difference between the resorber pressure p R and the intermediate pressure p z must be interpreted.
  • the changes in the state variables of the working fluid in the heat pump process of the above-described heat pump are schematically illustrated in a p, diagram. If the amount of gaseous working fluid component expelled by the external amount of heat Q E supplied in the degasser 12 is assumed to be additional in the degasser 34 and in the degasser 40 without additional external energy being supplied from the poor solution Quantities x and y are expelled from the gaseous working fluid component, for which heat energy still contained in the rich solution after exiting the resorber is used.
  • the gaseous amount y corresponds approximately to the amount y ', which would have been degassed with the heat of the rich solution in the additional degassing to degasser pressure PE .
  • the quantity y does not need to be compressed from the pressure p E , but only from the pressure p z > p E to the absorber pressure p R , which improves the performance figure.
