(54) СПОСОБ OCYUIKH БЛОКА ПЕРЕКЛЮЧАЮЩИХСЯ РЕГЕНЕРАТОРОВ ТУРБОХОЛОДИЛЬНОЙ УСТА1-ЮВКИ(54) OCYUIKH MODE OF SWITCHING REGENERATORS OF THE TURBO-CHOLODYLA UST1-SOUTH

Изобретение относитс к холодильной технике, в частности к способам осушки регенераторов воздушных турбохолодильных машин.The invention relates to refrigeration engineering, in particular, to methods for drying regenerators of aerial turbo-refrigerating machines.

Известен способ осушки регенераторов воздушных турбохолодильных машин при помощи воздуха, прошеашего компрессор и детанаер flj.There is a method of drying regenerators of air turbo-refrigerating machines with the help of air, a compressor and a de-aner flj.

Суш.ественный недостаток этого способа заключаетс в продолжительности осуш ки, а также в попадании капельной влаги на вход компрессора, что ухудшает услови его работы.The natural disadvantage of this method lies in the duration of drying, as well as in the ingress of drip moisture to the compressor inlet, which worsens the conditions of its operation.

Цель изобретени - повышение эффективности процесса осушки регенераторов, The purpose of the invention is to increase the efficiency of the process of drying regenerators,

Это достигаетс тем, что по предлагаемому способу сжатый воздух после компрессора дел т на два потока, один из которых направл ют в первый регенератор и далее выбрасывают в атмосферу, а BTOpoii - направл ют через детандер во второй регенератор, после которого к этому потоку подмешивают воздух, забираемый из атмос)еры, и полученную смесь подают па сжатие в компрессор. This is achieved in that according to the proposed method, the compressed air after the compressor is divided into two streams, one of which is sent to the first regenerator and then emitted into the atmosphere, and BTOpoii is directed through the detander to the second regenerator, after which air is mixed into this stream , taken from the atmosphere, and the resulting mixture is fed to the compressor.

На чертеже схематично представлена установка дл осуществлени способа осу11 ки регенераторов воздушной турбохолодильной машины.The drawing shows schematically an installation for implementing a method for inspecting a regenerator of an air turbo-cooling machine.

Машина содержит установленные на одном валу компрессор I и детандер ii, которые через периодически переключающиес клапанные коробки 3 и 4 соединены, с регенераторами 5 и 6 и с клапанной коробкой 7, отключающей во врем осушки холодильную камеру 8, а также дроссельный вентиль 9 и вентили 10 и 11, при помощи которых устанавливак т режим осушки регенераторов.The machine contains a compressor I and an expander ii mounted on the same shaft, which are periodically switched valve boxes 3 and 4 are connected to regenerators 5 and 6 and to the valve box 7 that turns off the refrigerating chamber 8 during drying and the throttle valve 9 and valves 10 and 11, by which the regenerator drying mode is set.

Машина в режиме осушки регенераторов работает следующим образом.The machine in the mode of drying regenerators works as follows.

Claims

Turn off the refrigerating chamber 8, close the valve 11, open the valves 9 and 10. Most of the air after the expander is directed through the valve boxes 7 and 4 to the regenerator. Drain the nozzle of the regenerator, the air is released into the atmosphere. A smaller part of the air is directed through the expander 2 to the regenerator 5, after which air from the atmosphere is squeezed into it through the valve 9. The resulting mixture is compressed into. compressor 1 The feasibility of applying the proposed method is to accelerate the process of complete drying of regenerators, as well as to provide normal conditions for the operation of the compressor and other engines, the claims, the method of drying the unit of switching regenerators of the turboholoil installation using air that has passed through the compressor and the expander It is also distinguished by the fact that, in order to reduce the efficiency of the drying process, the compressed air after the compressor is divided into two streams, one of which is directed to The second regenerator and aeler are emitted into the atmosphere, and the second is directed through the expander to the second regenerator, after which the aTONfy stream is mixed / g air taken from the atmosphere, and the resulting mixture is fed to the compressor for compression.
