AIR TURBO-COOLING PLANT (EMBODIMENTS), TURBOEXPANDER AND THE AIR TURBO-COOLING PLANT OPERATION METHOD (EMBODIMENTS) Russian patent published in 2018 - IPC F25B11/00 

FIELD: refrigerating equipment.

SUBSTANCE: invention relates to the refrigeration equipment and can be used in air conditioning systems, refrigerators, etc. Air turbo-cooling plant contains compressor located on one same shaft with the turboexpander, electric motor, two-cavity heat exchanger, recuperator, dehumidifier, refrigerating chamber with cooler and fan. Plant is equipped with the two-cavity heat exchanger-cooler, as well as the second and third dehumidifiers, by the output the compressor is connected to the heat exchanger first cavity, which is connected to the heat exchanger-cooler first cavity, through the second dehumidifier connected to the recuperator first cavity, through the first dehumidifier communicated with the input to the turboexpander, and through the third dehumidifier by the last output is connected to the heat exchanger-cooler second cavity, which is communicated with the cooler, and through the latter is to the recuperator second cavity, which is communicated with the compressor inlet.

EFFECT: enabling possibility to prevent the ice and frost formation on the turboexpander and pipelines internal cavities, which in turn allows to prevent the ATCP shutdown and to increase its cooling capacity.
