Abstract
A refrigeration unit (26) for a printing machine is presented. It comprises a dryer interface (28) connectable to a dryer unit (18) of the printing machine in a heat conductive manner and a print interface (30) connectable to a printing unit (14) of the printing machine in a heat conductive manner, wherein the refrigeration unit (26) is adapted to transfer heat (32, 34) from the print interface (30) to the dryer interface (28). Furthermore, a printing machine is described. It comprises a printing unit (14) adapted for printing on a web of carrier material, a dryer unit (18) being adapted for drying printed web of carrier material, and a refrigeration unit (26) as mentioned above.
Claims18
A printing machine comprising:
- a printing unit adapted for printing on a web of carrier material, the printing unit including a printing drum;
- a dryer unit adapted for drying the web of carrier material;
- and
- a refrigeration unit comprising:
- a coolant circuit having:
- a first coolant circuit portion at least partially located inside the printing drum of the printing unit, wherein the first coolant circuit portion is adapted for absorbing heat originating from the printing drum of the printing unit, and
- a second coolant circuit portion positioned in the dryer unit or adjacent to the dryer unit, wherein the second coolant circuit portion is adapted for delivering heat to the dryer unit,
- wherein the refrigeration unit is adapted to transfer heat from the first coolant circuit portion adapted for absorbing heat originating from the printing drum to the second coolant circuit portion adapted for delivering heat to the dryer unit.
A printing machine comprising:
- a refrigeration unit comprising:
- a coolant;
- a first coolant portion at least partially inside a printing drum of a printing unit of the printing machine to transfer heat into the coolant from the printing drum of the printing unit of the printing machine;
- and
- a second coolant portion to deliver the transferred heat, from the printing drum of the printing unit by the first coolant portion, in the coolant to a dryer unit of the printing machine.
A printing machine comprising:
- a printing unit including a printing drum;
- and
- a refrigeration unit comprising:
- an evaporator for a printing unit of the printing machine, the evaporator to absorb heat from at least a portion of the refrigeration unit inside the printing drum of the printing unit to cool the printing drum of the printing unit;
- and
- a condenser for a dryer unit of the printing machine, the condenser to deliver the absorbed heat from the printing drum of the printing unit to the dryer unit.
