 at least one evaporating channel separated from the cooling channel by a transfer wall and having an inflow opening which is connected for medium throughflow to the outflow opening of the cooling channel, and an outflow opening, and 
 means for wetting the side of the transfer wall directed toward the evaporating channel, and 
 a drying device for drying the airflow, comprising: 
 a drying channel with an inflow opening for the airflow for drying and an outflow opening for the dried airflow, 
   characterized in that   the outflow opening of the cooling channel of the cooling device and/or the outflow opening of the evaporating channel of the cooling device is connected for medium throughflow to the inflow opening of the drying device.   
     
     
         2 . The system as claimed in  claim 1 , wherein the outflow opening of the drying device is connected for medium throughflow to the inflow opening of the cooling channel of the or a cooling device. 
     
     
         3 . The system as claimed in  claim 1 , comprising two cooling devices, wherein the outflow opening of the drying device is connected for medium throughflow to the inflow opening of the cooling channel of the one cooling device, and wherein the outflow opening of the cooling channel of the other cooling device and/or the outflow opening of the evaporating channel of the other cooling device is connected for medium throughflow to the inflow opening of the drying device. 
     
     
         4 . The system as claimed in  claim 1 , comprising a heat exchanger which is connected on the one side for medium throughflow to the outflow opening of the cooling channel of the cooling device and/or the outflow opening of the evaporating channel of the cooling device, and which is connected on the other side for medium throughflow to the inflow opening of the drying device and/or the inflow opening of the cooling channel of the cooling device. 
     
     
         5 . The system as claimed in  claim 4 , wherein the heat exchanger is connected on the one side for medium throughflow to the outflow opening of the cooling channel of the cooling device and connected on the other side for medium throughflow to the inflow opening of the cooling channel of the cooling device and/or the inflow opening of the drying device, and wherein the outflow opening of the cooling channel and/or the outflow opening of the evaporating channel of the cooling device is connected for medium throughflow to the inflow opening of the drying device. 
     
     
         6 . The system as claimed in  claim 5 , wherein the system is a closed system in respect of at least the airflow. 
     
     
         7 . The system as claimed in  claim 6 , wherein the value for the air pressure in the system is between 0.5 bar-3 bar. 
     
     
         8 . The system as claimed in  claim 1 , wherein the drying device comprises drying means for drying the airflow. 
     
     
         9 . The system as claimed in  claim 8 , wherein the amount of moisture which the drying means can absorb relative to the dry weight of the drying means increases with a rise in the relative air humidity. 
     
     
         10 . The system as claimed in  claim 9 , wherein from a determined value of the relative air humidity the amount of moisture which the drying means can absorb relative to the dry weight of the drying means increases at least more or less exponentially with a rise in the relative air humidity.
