Multi-evaporation cooling system

A multi-evaporation cooling system, comprising:

• a reciprocating compressor (1) provided with two suction paths coupled to two distinct evaporation lines (Levap 1, Levap 2);
• wherein
• the first evaporation line (Levap 1) comprises a first expansion device (41), a first evaporator (51) and a first intermediate heat exchanger (61);
• the second evaporation line (Levap 2) comprises a second expansion device (42), a second evaporator (52) and a second intermediate heat exchanger (62);
• said multi-evaporative cooling system being characterized by the fact that:
• the first intermediate heat exchanger (61) of the first evaporation line (Levap 1) comprises a first segment of the first expansion device (41) physically disposed in contact with a portion of the second evaporation line (Levap 2), downstream of said second evaporator and upstream of a suction inlet of the reciprocating compressor (1);
• the second intermediate heat exchanger (62) of the second evaporation line (Levap 2) comprises a first segment of the second expansion device (42) physically disposed in contact with a portion of the first evaporation line (Levap 1) downstream of said first evaporator (51) and upstream of the suction inlet of the reciprocating compressor (1);
• and in that
• said first segment of the first expansion device (41) in the first intermediate heat exchanger (61) comprises a same capillary tube as a second segment of the first expansion device (41) arranged downstream of said first segment of the first expansion device (41) and upstream of said first evaporator (51);
• said first segment of the second expansion device (42) in the second intermediate heat exchanger (62) comprises a same capillary tube as a second segment of the second expansion device (42) arranged downstream of said first segment of the second expansion device (42) and upstream of said second evaporator (52);
• wherein the first segment of the first expansion device of the first evaporation line is individually and fluidically isolated from the first segment of the second expansion device of the second evaporation line.
