Scroll machine and refrigeration system

A scroll machine (2) comprising

• a housing (10), a first spiral unit (14) arranged in the housing (10) and having first spiral channel, and a second spiral unit (18) arranged in the housing (10), wherein the first spiral unit (14) can be moved relative to the second spiral unit (18) along an orbital path, wherein the first spiral unit (14) and the second spiral unit (18) are arranged so as to axially interlock for forming pressure chambers, and wherein the second spiral unit (18) comprises:
• a second spiral channel,
• a second spiral rib (26) extending along a spiral path curve (82) and having rib flank (28) radially delimiting the second spiral channel,
• a second spiral channel floor (30) axially delimiting the second spiral channel, and
• at least one medium channel (32, 54, 66) extending within the second spiral rib (26) for guiding a working medium,
• wherein the rib flank (28) has at least one outlet opening (68) through which the at least one medium channel (32, 54, 66) opens into the second spiral channel,
• characterized in that
• the at least one outlet opening (68) is arranged, in an axially spaced manner, at a floor distance (70) from the second spiral channel floor (30).
