The invention relates to a method for drying a chamber comprising a predominantly protective-gas atmosphere in the chamber under positive pressure, which has an operating pressure p1 and a predetermined minimum pressure pmin, wherein the minimum pressure pmin of the gas chamber is monitored and the operating pressure p1 is greater than the minimum pressure pmin, wherein the method comprises the following steps: a) removing of a partial quantity Vi of the protective gas from the chamber, wherein the partial quantity Vi is equivalent to the pressure differential Δp, which is smaller or equal to the differential between p1 and pmin, b) introducing a partial quantity V2 of a dry or dried protective gas into the gas chamber up to a gas pressure p2, which is greater than pmin and c) repeating method steps a) and b) after a predetermined waiting time Δt. The invention further relates to an arrangement for carrying out the method.
A method for drying a gas space with a protective gas atmosphere prevailing in the gas space under a positive pressure with an operating pressure p1 and a predetermined minimum pressure pmin, wherein the predetermined minimum pressure pmin of the gas space is monitored and the operating pressure p1 is greater than the minimum pressure pmin, wherein the method comprises the following steps:
An arrangement comprising a first and a second gas space (1, 2) filled with a protective gas, a line system (12) connecting the first and the second gas spaces (1, 2), at least one compressor (3) arranged in the line system (12), at least one gas drying unit (4) arranged in the line system (12), means for detecting the gas pressure inside the line system (12), valves (5.1, 5.2, 5.3, 5.4), which can be controlled in such a way that the compressor (3) can alternately convey gas from the first gas space (1) into the second gas space (2) and can convey gas from the second gas space (2) into the first gas space (1), means for controlling the compressor as a function of the pressure inside the line system (12) and means for controlling the valves (5.1, 5.2, 5.3, 5.4) as a function of the desired direction of conveyance of the gas.
