Claim 11:
12. The method according to claim 11, wherein
the at least one operational parameter comprises a compressor speed of the at least one piston compressor,
the adjusting of the at least one operational parameter of the at least one controllable pressure medium supplying device based on the difference between the selected value for the rate of cooling of the pressure medium in the treatment region during the cooling phase and the determined rate of cooling during the cooling phase includes
adjusting the compressor speed of the at least one piston compressor based on the difference between the selected value for the rate of cooling of the pressure medium in the treatment region during the cooling phase and the determined rate of cooling during the cooling phase; and

the method further includes
in response to a determination that the compressor speed of the at least one compressor is within a predefined compressor speed range subsequently to decreasing the piston stroke length of the at least one piston compressor from the first piston stroke length to the second piston stroke length, increasing the piston stroke length of the at least one piston compressor back towards or to the first piston stroke length.
