    Invention o l iiocmoii to tsp. kpc chi.icke and iipuxieiKMio can be used when using the heat content of weak solutions formed during desorption of the working medium and; 1 and during thermal separation, especially when absorbed 11, ion1x or desorption processes with vapor of the working substance for refrigeration and in sorbic heat pumps used for heating and air conditioning.
    A known method of using the heat of a weak solution by recirculating the solution in absorption chillers, thereby eliminating excess heat in the boiler itself and preliminary evaporation of the strong solution of Gesamte Kalteiridustrie, Vol. 20, 1913, p. 1-9. 114-111, 150-161 and t: 21, 1914, p. 7-14, 21-24).
    The disadvantage of this method is that its 1p-1zka thermodynamic efficiency is due to the possibility of realizing () L1, as with the use of rallying pavivk (rude, KOTOpiJC are unreliable in operation.
    There is also a known method of using the heat of a weak solution by ocyiiiecTBJie- 1 of the backflow in the oron phase during film flow around the mixture inside the vertical 1) of tube bundles and heated outside the interstitial pipeline {-li iUe, t 2, 28th ed., P. 244).
    The disadvantage of this method is that the low efficiency of the Fewst 1-; evisoko1- () heat transfer coefficient between weak and strong solutions.
    The most important to the invention but technical support and the achieved result is crioco6 using the heat of C. pabo) solution by means of reheperative heat exchange between weak and cramped solutions, which have a significant difference in concentrations (GDR patent No. 1249.46, class F 25 J 3/02, Ozublnk. 1977).
    The disadvantages of the method - or |) ain-ineH ie cooling the coolant and bo; nlna temperature difference between the el | | m and strong solutions.
    The purpose of the invention is the understanding of ecopromicity by more no,: inoro ispol1) 3po-pipe heat of a weak solution.
    This goal is achieved by the fact that our method of using a solution of c.-ia6oro solution by means of regenerative heat exchange between weak and strong solutions, having an impressive concentration of 1 pp, strong solution is divided into two parallel streams, one of which they are directed into the boiler and the other into the boiler of the partial flow, irrigate these streams, respectively, one heating beam in the boiler and one or more heating beams in the boiler of the partial flow with the formation of weak solutions, combine both flowsin the general note of a weak solution and served in the regenerator



    55827.
    The partial heat exchanger of the partial flow is countercurrent to a strong partial flow heat exchanger. In addition, another stream of strong solution is additionally heated by an external heat carrier in the beam 5 of heating.
    The drawing shows the installation diagram that implements the method.
    The installation contains a boiling unit 1, a boiling unit 2 of a partial flow, a copreciprocal column 3, heating nooks 4 and 8, a separation device 5, a mass exchange device 6, a regenerative heat exchanger 7, an inlet 9 of extraneous heat. liquid collectors, 10-sided heat carrier output, withdrawal of a weak solution 11, supply of a 12 fixing solution 12, selection of 13 refrigerant vapors, distributor 14, supply of cooling medium 15, cooling selection 16, its medium and a reflux condenser 17.
    The adjustment is as follows.
    A strong solution after the supply of 12 enters into) as11re, ae. 1.l. 14 and is divided into two streams, one and: -; to (; then |) they are sent to the boiler 1, and the second - to parallo vk, 110chipn1 1Y kinn gnlyshchk 2 partial flow. 1- separation takes place according to the relevant; 1 salt, Yergan1 to c; ia6oro solution, collecting in the lower parts of the boiler 1, and the boiler 2 partially - the I -o stream ripn of insignificant and economically justified differences in temperature. between the general flow of the weak solution in 30 as the medium of heating in the regenerative heat exchanger 7 of the boiler 2 and the second flow of the strong solution. After that, a strong solution through the separation device 5 will flow into the boiler and the boiler 2 partially in the flow. Separation of a solid solution 35 flows: it can 1) oisch (, 1dit and after .. passing through) without masses (} exchange device 6.
    A strong solution flows in the film nid through the device 6 and the beam 4 in the boiler 1, respectively, through the device 6 and the heat exchanger 7 or the heat exchanger 7 and the beam of the 8 n boiler 2 of the partial flow. The light components are thermally separated, and the resulting weak solution is collected in the lower parts of the boiling bodies of peaks 1 and 2. Then the two flows of the weak heating section are united, and the total flow as a heating medium is directed to the heat exchanger 7 The boiler 2 is counterflowed against the top-down strong solution and at the same time cools down. After 50 seconds, the solution through tap 1 is removed from the plant.
    Separate components (refrigerant) are also passed in countercurrent to a strong solution, but in direct contact with it, through mass transfer devices 6, where 55 their concentration increases, which grows in the upward direction. Depending on the concentration of supplied crepe 40

    Of which solution or the required purity, a steam coolant having an inlet 9 and a refrigerant at the selection 13 is set to conc. 10.
    A centric column 3, placed by you-Economic efficiency, will invent the supply of a strong solution. For this marriage, the reflux condenser 17 serves as a rational consumption, with the supply of foreign coolant and selection 16 of the cooling medium. 5Arranged by results
