Abstract

The present invention relates to a method for filling a fluid (2) into the cooling circuit (1) of air-conditioning systems, in particular into those of motor vehicle air-conditioning systems, in which method the fluid (2) which is to be filled in is stored at approximately atmospheric pressure in a container (3), in which method a filling line (11) is connected to the cooling circuit (1), which filling line (11) can be connected by means of an initially closed valve (10) to a riser line (7) which dips into the fluid (2) which is to be filled in, in which method the filling line (11) is then evacuated, and in which method the valve (10) is subsequently opened such that the fluid (2) which is stored under approximately atmospheric pressure rises through the riser line (7) into the evacuated filling line (11). The invention is based on the problem of preventing the undesired infiltration of moisture into the cooling circuit (1). In order to solve said problem, the fluid (2) which is stored in the container (3) is closed off in an air-tight fashion by means of a cover (4) which is in contact with the fluid (2). The air-tight closure prevents moisture from the atmosphere from infiltrating into the cooling circuit (1) via the hygroscopic fluid (2).
