1. A respirator comprising: an inspiration branch;an expiration branch receiving an expired fluid flow;a breathing gas cooler for cooling gas in said expiration branch, at least a portion of said breathing gas cooler being exposed to only said expired fluid flow in said expiration branch; anda control means for controlling activation of said breathing gas cooler such that an amount of condensation formed in said expiration branch is controlled via said control means, said breathing gas cooler comprising a Peltier element having a warm side and a cold side, said inspiration branch receiving an inspired fluid flow, said warm side being exposed only to said inspired fluid flow in said inspiration branch, said cold side being exposed to only said expired fluid flow, wherein said warm side is not in direct fluid communication with said expired fluid flow, and said cold side is not in direct fluid communication with said inspired fluid flow. 2. A respirator in accordance with claim 1, wherein said warm side of said Peltier element is positioned in contact with gas in said inspiration branch, said inspiration branch comprising an inspiration line, said expiration branch comprising an expiration line, said warm side being arranged in said inspiration line, said warm side being in contact with the inspired fluid flow in said inspiration line such that said inspired fluid flow is heated via said warm side, said cold side being arranged in said expiration line, said cold side being in contact with said expired fluid flow in said expiration line such that said expired fluid flow is cooled via said cold side, wherein said cold side removes heat from said expired fluid flow such that condensation of water forms, wherein said control means controls power supplied to said Peltier element to control a transfer of heat from said cold side to said warm side, whereby a temperature of said cold side and a temperature of said warm side are controlled via said control means. 3. A respirator in accordance with claim 2, wherein said expiration branch has an additional Peltier element with a warm side and a cold side as an additional breathing gas cooler, said cold side of said additional Peltier element being exposed to at least one expired fluid flow in said expiration branch. 4. A respirator in accordance with claim 3, wherein said warm side of said additional Peltier element is arranged in a channel, through which cooling air flows. 5. A respirator in accordance with claim 2, wherein said breathing gas cooler is part of a respiration system that can be coupled with respirator components. 6. A respirator in accordance with claim 2, wherein said inspiration branch and said expiration branch comprise a flexible breathing tube system and said breathing gas cooler is a component that can be coupled with said flexible breathing tube system. 7. A respirator in accordance with claim 2, further comprising: a power supply for supplying power to said Peltier element in a breathing flow-controlled manner. 8. A respirator in accordance with claim 2, wherein said Peltier element receives control data from said control means. 9. A respirator comprising: a breathing tube system with an inspiration branch and an expiration branch, said inspiration branch receiving an inspired gas flow, said expiration branch receiving an expired gas flow;a means for supplying breathing gas to the inspiration branch;a breathing gas cooler for cooling gas in said expiration branch, wherein said breathing gas cooler cools said expired gas flow such that moisture in said expired gas flow condenses to form water condensation; anda control device controlling activation of said breathing gas cooler, wherein said control device controls an amount of water condensation formed in said expiration branch, said breathing gas cooler comprising a Peltier element having a warm side and a cold side, said warm side of said Peltier element being exposed to only said inspired gas flow in said inspiration branch, said cold side being arranged in said expiration branch, said cold side being exposed to only said expired gas flow, wherein said warm side is not in direct fluid communication with said expired gas flow, and said cold side is not in direct fluid communication with said inspired gas flow. 10. A respirator in accordance with claim 9, wherein said control device controls an amount of electricity supplied to said Peltier element such that said control device controls a transfer of heat from said cold side to said warm side, wherein a temperature of said cold side and a temperature of said warm side are controlled by said control device. 11. A respirator in accordance with claim 10, further comprising a water condensation collecting line, said water condensation collecting line receiving said water condensation, wherein said expiration branch has an additional Peltier element with a warm side and a cold side as an additional breathing gas cooler, said cold side of said additional Peltier element being exposed to at least one expired gas flow in said expiration branch. 12. A respirator in accordance with claim 11, wherein said warm side of said additional Peltier element is arranged in a channel, through which cooling air flows. 13. A respirator in accordance with claim 12, further comprising: a power supply for supplying power to at least one of said Peltier element and said additional Peltier element in a breathing flow-controlled manner. 14. A respirator in accordance with claim 13, wherein one or more of said Peltier element and said additional Peltier element receives control data from said control device. 15. A respirator system comprising: a respirator with respirator components;a breathing tube system with an inspiration branch and an expiration branch connected to said respiration components, said inspiration branch receiving an inspired gas flow, said expiration branch receiving an expired gas flow;a breathing gas cooler module for cooling gas in said expiration branch, said breathing gas cooler module being coupled with said respirator components and being disconnectable therefrom, said breathing gas cooler module comprising a Peltier element having a warm side portion and a cold side portion, said warm side portion being arranged in only said inspiration branch, said warm side portion being exposed to only said inspired gas flow, said cold side portion being arranged in only said expiration branch, said cold side portion being exposed to only said expired gas flow such that heat is removed from said expired gas flow via said cold side portion to form water condensation, wherein said warm side portion is not in direct fluid communication with said expired gas flow, and said cold side portion is not in direct fluid communication with said inspired gas flow; anda control means for controlling power supplied to said Peltier element such that said control means controls an amount of heat transferred from said cold side portion to said warm side portion, wherein said control means controls an amount of said water condensation formed in said expiration branch. 16. A respirator system in accordance with claim 15, wherein said Peltier element thermally couples said expiration branch with said inspiration branch, said inspired gas flow having a first inspired gas temperature, said warm side portion being in contact with said inspired gas flow, said warm side portion heating said inspired gas flow such that said inspired gas flow has a second inspired gas temperature, said expired gas flow having a first expired gas temperature, said second inspired gas temperature being greater than said first inspired gas temperature, said expired gas flow being cooled via said cold side portion such that said expired gas flow has a second expired gas temperature, said second expired gas temperature being less than said first expired gas temperature. 17. A respirator system in accordance with claim 16, wherein said expiration branch has an additional Peltier element with a warm side and a cold side as an additional breathing gas cooler, said cold side of said additional Peltier element being exposed to at least one expired gas flow in said expiration branch. 18. A respirator system in accordance with claim 16, further comprising: a power supply for supplying power to said Peltier element in a breathing flow-controlled manner, wherein said Peltier element receives control data from said control means.
