Abstract

See full text

A refrigeration unit with dynamic air cooling is described. It includes a centrifugal compressor with an electric drive, whose outlet is connected to a working element, whose outlet is connected to the inlet of a turbine. The turbine is connected to an electrical energy generator, where the outlet of the turbine is directed towards a wall-pipe heat exchanger. The heat exchanger is connected to a pump. Between the centrifugal compressor and the working element there is a pipe-wall exchanger of the air-air type, to which a fan is connected. The working element of the unit has a cylindrical hollow profile comprising helical recesses with a substantially oval shape.
