AIR TURBOREFRIGERATION PLANT Russian patent published in 2005 - IPC

FIELD: cooling equipment, particularly refrigerators including turbo-expanders operating within wide range of cooling temperatures.

SUBSTANCE: turborefrigeration plant comprises turbo-expander, multi-compartment dynamic heat-exchanger, user of refrigeration, power source and centrifugal turbocompressor. Centrifugal turbocompressor is divided into low-pressure and high-pressure centrifugal stages. Low-pressure stage is mechanically linked with power source. High-pressure stage is mechanically connected to turboexpander. The first heat-exchanger compartment inlet communicates with outlet of user of refrigeration through channel, outlet thereof communicates with atmosphere. The second heat-exchanger compartment inlet is connected to low-pressure turbocompressor stage outlet and outlet thereof is linked with high-pressure turbocompressor stage inlet. The third heat-exchanger compartment inlet is connected to high-pressure turbocompressor stage outlet, outlet thereof is linked with turbo-expander inlet.

EFFECT: increased refrigeration performance, increased reliability of plant actuation and operation, simplified structure, increased operational economy.
