Patent ID: 8505317

Claim:
A refrigerating device comprising: a main compressor; a condenser downstream of and in fluid communication with said main compressor; main expansion means downstream of said condenser; an evaporator downstream of and in fluid communication with said main expansion means; and a turbocompressor unit in fluid communication between said evaporator and said main compressor and in fluid communication with at least one heat exchanger, said at least one heat exchanger having: a hot branch connected upstream, via an inlet line, to said condenser and downstream, via an outlet line, to said main expansion means; and a cold branch connected, upstream, to an expansion means mounted on a branch of said inlet line to said condenser and connected, downstream, to a turbine portion of said turbocompressor unit, wherein said cold branch being connected downstream to said turbine portion enables fluid communication between said at least one heat exchanger and said turbocompressor unit.
