Abstract: The European Xray Free Electron Laser EuXFEL is operating since 2016. The technical systems for cooling and ventilation CV were designed, built and commissioned by the DESY work package WP34. The water cooling systems consists of 3 cooling systems: 30/45°C low conductivity water LCW for klystron, power converter and magnet cooling; 20/30°C LCW for tunnel rack cooling and 8/14°C for air conditioning and for air-drying. The ventilations of the tunnels are connected to a serial ventilation system. The air flow starts from the experimental hall in opposite direction of the beams until to the injector. The series ventilation system of the tunnels saves costs for air treatment like cooling, heating and air-drying. The tunnel walls are a good heat storage that increases the air temperature stability by a factor of ten. The advantages of this concept will be described.
