Claims
- 1. A plant for heating a liquid medium, comprising
a feed line for feeding the medium to be heated; a first thermal system having a first heat exchanger, said first heat exchanger having an inlet line adjoining the feed line, and an outlet line; a first control element arranged between the feed line and the inlet line; a bypass line equipped with a second control element running from the feed line to the outlet line; a line section running from the outlet line to the at least one second thermal system, and wherein the outlet line is connected to the inlet line through a recirculation line having a third control element and a first pump, said recirculation line being arranged parallel to the first heat exchanger.
- 2. The plant as claimed in claim 1, wherein the at least one second thermal system has a second heat exchanger and a tank for receiving a quantity of the medium in a liquid state, said second heat exchanger is connected to the tank through a supply line running from the tank to the second heat exchanger and through a return line running from the second heat exchanger back to the tank.
- 3. The plant as claimed in claim 2, wherein a fourth control element is arranged in the outlet line downstream of the point at which the recirculation line branches off from the outlet line.
- 4. The plant as claimed in claim 2, wherein the line section runs to the tank of the at least one second thermal system.
- 5. The plant as claimed in claim 2, wherein the line section opens into the supply line.
- 6. The plant as claimed in claim 2, wherein a circulation pump is arranged in the supply line.
- 7. The plant as claimed in claim 1, wherein the first pump arranged in the recirculation line is designed for delivery of the medium from the outlet line to the inlet line.
- 8. The plant as claimed in claim 1, wherein the first pump arranged in the recirculation line is designed for delivery of the medium from the inlet line to the outlet line.
- 9. The plant as claimed in claim 2, wherein a line opening into the outlet line and having a pump delivering in the direction of the outlet line and a control element is branched off from the second heat exchanger.
- 10. The plant as claimed in claim 2, wherein a line opening into the outlet line and having a further pump and a further control element is branched off from the tank.
- 11. The plant as claimed in claim 2, wherein a line opening into the outlet line and having a pump delivering in the direction of the outlet line and a control valve is branched off from the supply line.
- 12. The plant as claimed in claim 2, wherein a line opening into the inlet line and having a pump delivering in the direction of the inlet line and a control element is branched off from the at least one second heat exchanger.
- 13. The plant as claimed in claim 2, wherein a line opening into the inlet line and having a pump delivering in the direction of the inlet line and a control element is branched off from the tank.
- 14. The plant as claimed in claim 2, wherein a line opening into the inlet line and having a pump delivering in the direction of the inlet line and a control element is branched off from the supply line.
- 15. The plant as claimed in claim 2, wherein a line opening into the recirculation line and having a control element is branched off from the second heat exchanger.
- 16. The plant as claimed in claim 2, wherein a line opening into the recirculation line and having the control element is branched off from the tank.
- 17. The plant as claimed in claim 2, wherein a line opening into the recirculation line and having the control element is branched off from the supply line.
