Description

Как видно из табл. 1 и 2, давление насыщенных паров воды над растворами отличаютс  незначительно, однако при (температура абсорбции) кристаллизаци  CaCpj aa водного раствора начинаетс  при 51,3%, а смеси . Ca(NOi), ( et 5/1) при 60,2%. Следовательно, предельна  рабоча  Область концентраций раствора НчО (МО j)j , по сравнению с раствором - CaCPj, будет увеличена, примерно на 9 абс.%, что свидетельств ет о большей эксплуатационной надежности машины, использующей раствор HjO - ,-Ca{N05)i по сравнению с хлористокальциевой АХМ.As can be seen from the table. 1 and 2, the pressure of saturated water vapor above the solutions differs slightly, but at (absorption temperature) the CaCpj aa crystallization of the aqueous solution begins at 51.3%, and the mixture. Ca (NOi), (et 5/1) at 60.2%. Consequently, the limiting working area of the concentration of the NCHO solution (MO j) j, as compared with the solution — CaCPj, will be increased by approximately 9 abs.%, Which indicates a greater operational reliability of the machine using the solution HjO -, -Ca {N05) i compared to chloride calcium AHM.

шин показало уменьшение кратности циркул ции и, как следствие, уменьшение тепловых нагрузок на теплообменник и абсорбер АХМ, использующей раствор HjrO - CaCSj,- Са(МО), по сравнению с хлористокальциевой АХМ. При этом сохран етс  термодинамическа  эффективность на уровне хлористокальциевой АХМ. Увеличение зоны дегазации , по сравнению с раствором Hj O-CaCC позвол ет использовать дл  предлагаемой АХМ греющие источники более низкого потенциала.tires showed a decrease in the rate of circulation and, as a result, a decrease in heat loads on the heat exchanger and the AXM absorber using the HjrO – CaCSj, –Ca (MO) solution, as compared to the chloride-calcium AHM. At the same time, thermodynamic efficiency is maintained at the level of chloride-calcium AXM. The increase in the degassing zone, as compared with the HjO-CaCC solution, allows the heating sources to use a lower potential for the proposed AHM.

Технико-экономическа  эффективность заключаетс  в повьвиении эксплуатационной надежности мгопины и в расширении диапазона получаемых температур .Technical and economic efficiency consists in improving the operational reliability of the system and in expanding the range of temperatures obtained.
