Abstract

Invention m. B. used in refrigeration. The purpose of the invention is to increase the cooling capacity of the screw using the screw expander. The gas is compressed in compressor 1, cooled in cooler 2 to ambient temperatures and separated in separator 3 into gas and liquid phases. After separation, the liquid phase is directed to the inlet of the screw expander 6 for co-dispersing it with the gas and removing heat from the latter, and the mixture obtained in the expander is fed to the cooled object. 1 il.

The invention relates to refrigeration technology, more specifically to gas refrigeration units.

The purpose of the invention is to increase the cooling capacity when using a screw detander.

The drawing shows a diagram of the gas refrigerating machine, which implements the proposed method.

Gas refrigerating machine contains Compressor 1, cooler 2, separators 3 1 4, recuperative heat exchanger 5, screw expander 6, cooling object nach if Dsos 8.

The procedure is carried out as follows. i

The gas is compressed in compressor 1, cooled in cooler 2 to ambient temperature, and separated in separator 3 into gas and liquid phases. The liquid phase is directed to the gas stream at

The expander 6, and then into the cooled object 7, where the mixture is heated, and after separating it in the separator 4 into the gas and liquid phases, the latter is directed by the pump 8 to the inlet of the screw expander 6 to expand with the gas when the latter is supplied with heat. The gas phase after the separator 4 is fed back to the recuperative heat exchanger 5 and further to the inlet of the compressor 1.
