1. A method of operating a pressing arrangement, the pressing arrangement including a pressure vessel configured to hold pressure medium therein during use of the pressing arrangement, the pressure vessel including a treatment region therein, wherein the treatment region is configured to accommodate at least one article, wherein the pressing arrangement is configured to subject the at least one article to a treatment cycle including a cooling phase, wherein the pressure vessel is configured to direct the pressure medium to enter and exit the treatment region, the pressing arrangement further including at least one controllable pressure medium supplying device configured to transport the pressure medium during the cooling phase from another region in the pressing arrangement to the treatment region, wherein a temperature of the pressure medium in the other region is lower than a temperature of the pressure medium in the treatment region during at least part of the cooling phase such that the temperature of the pressure medium in the treatment region decreases based on the transport of the pressure medium during the cooling phase from the other region to the treatment region, wherein the at least one controllable pressure medium supplying device is controllable at least with respect to a pressure medium supplying rate, to control a rate of transport of the pressure medium from the other region to the treatment region, based on control of at least one operational parameter of the at least one controllable pressure medium supplying device, the method comprising:
obtaining at least one value indicative of at least one temperature in the pressure vessel during the cooling phase; and
based on the at least one value indicative of the at least one temperature in the pressure vessel during the cooling phase, adjusting the at least one operational parameter of the at least one controllable pressure medium supplying device to adjust the pressure medium supplying rate of the at least one controllable pressure medium supplying device to adjust the rate of transport of the pressure medium from the other region to the treatment region during the cooling phase,
wherein the at least one controllable pressure medium supplying device comprises at least one compressor, the at least one compressor being configured to cause the pressure medium to be transported during the cooling phase from the other region to the treatment region based on operation of the at least one compressor,
wherein the at least one operational parameter of the at least one controllable pressure medium supplying device is at least one operational parameter of the at least one compressor.
