REFRIGERATING PLANT Russian patent published in 2012 - IPC F25D13/00 F25D11/00 

FIELD: power industry.

SUBSTANCE: refrigerating plant contains heat-insulating body of hopper type with refrigerating chamber, heat-insulating cover, two chilling machines, outer het-insulating body with heat-insulated refrigerating chamber installed in working volume. Chilling machines are of vapour compression type. The first chilling machine serves for chilling of refrigerating chamber useful capacity, the other one serves for chilling of heat-insulating body inner volume which forms heat screen. Evaporator of the first chilling machine is brazed to inner wall of heat-insulating body while evaporator of the second chilling machine is brazed to inner wall of outer heat-insulating body along its all height. Chilling machines contain compressors (6), (12), condensers (7), (13), recuperative heat-exchangers, throttlers and evaporators which layout and connections are specified in patent application.

EFFECT: this invention allows reduction of plant dimensions due to reduction in thickness of required insulation.
