Известны способы получени  холода в абсорбционных холодильных установках путем отвода теплоты абсорбции хладагента водой в нижней части абсорбера, а в верхней - крепким раствором, раздел емым на два потока , один из которых при температуре кипени  подают на разделение в ректификационную колонну на уровне, превышающем ввод второго потока.There are known methods for obtaining cold in absorption chillers by removing the heat of absorption of the refrigerant by water in the lower part of the absorber, and in the upper part by a strong solution divided into two streams, one of which at boiling point is fed to the separation in a distillation column at a level exceeding the second flow.

Целью изобретени   вл етс  повышение теплового к.п.д. установки.The aim of the invention is to increase the thermal efficiency. installation.

Это достигаетс  тем, что по предлагаемому способу из потока при температуре начала кипени  отбирают часть, подогревают ее слабым раствором, подаваемым из куба ректификационной колонны, а затем смешивают со вторым потоком перед вводом его в ректификационную колонну.This is achieved in that according to the proposed method, a part is taken from the stream at the initial boiling point, heated with a weak solution supplied from the bottom of the distillation column, and then mixed with the second stream before entering it into the distillation column.

На чертеже схематически изображена абсорбционна  холодильна  установка, содержаща  ректификационную колонну без обратной подачи слабого раствора в ней.The drawing shows schematically an absorption refrigeration unit comprising a distillation column without a reverse feed of a weak solution therein.

Установка работает следующим образом.The installation works as follows.

Хладагент из испарител  1 через переохладитель 2 поступает в абсорбер 3 двум  потоками , в котором поглощаетс  слабым раствором . В нижней части абсорбера теплота абсорбции отводитс  водой, а в верхней - крепким раствором, который из куба абсорбера 3 насосом 4 подаетс  в регенеративную частьThe refrigerant from the evaporator 1 through the subcooler 2 enters the absorber 3 in two streams, in which it is absorbed in a weak solution. In the lower part of the absorber, the heat of absorption is removed by water, and in the upper part, by a strong solution, which is fed from the cube of the absorber 3 by pump 4 to the regenerative part.

5 абсорбера 3, где подогреваетс  теплотой абсорбции хладагента.5 of the absorber 3, where it is heated by the heat of absorption of the refrigerant.

При подогреве крепкого раствора до температуры начала кипени  его дел т на два потока , один из которых выводитс  из аппарата , а другой продолжает кипеть с образованием парол идкостной смесн и подаетс  на разделенне в ректификационную колонну 6.When a strong solution is heated up to the initial boiling point, it is divided into two streams, one of which is removed from the apparatus, and the other continues to boil to form passwords and liquid mixtures and is fed to the fractionation column 6.

Выведенный из регенеративной части абсорбера первый из потоков крепкого раствора в свою очередь делитс  на два потока (части), один из которых подают, например, в теплообменник 7 на подогрев слабым раствором, смешивают после теплообменника с парожидкостной смесью, выводимой из верхней части абсорбера 3, и направл ют в ректификационную колонну 6.The first of the strong solution streams withdrawn from the regenerative part of the absorber, in turn, is divided into two streams (parts), one of which is fed, for example, to the heat exchanger 7 for heating with a weak solution, is mixed after the heat exchanger with a vapor-liquid mixture withdrawn from the upper part of the absorber 3, and sent to distillation column 6.

Втора  часть потока при температуре кицени  направл етс  непосредственно на разделение на уровне, превыщающем ввод парожидкостной смеси.The second part of the stream, at a Kizena temperature, is sent directly to the separation at a level that exceeds the input of the vapor-liquid mixture.

Такое распределение потоков крепкого раствора сннлсает флегмовое число, что повыщает тепловой коэффициент установки.This distribution of flows of a strong solution increases the reflux number, which increases the thermal coefficient of the installation.
