         16 . A refrigerant exchange arrangement with a first oil-trapping chamber and a second oil-trapping chamber, the second oil-trapping chamber being located inside the first oil-trapping chamber, wherein a gas path out of the second oil-trapping chamber is limited by a wall of the first oil-trapping chamber and that an insert is arranged in the second oil-trapping chamber, which limits the gas path together with the wall of the first oil-trapping chamber. 
     
     
         17 . The refrigerant exchange arrangement according to  claim 16 , wherein the outside of the insert has at least one spirally shaped groove. 
     
     
         18 . The refrigerant exchange arrangement according to  claim 16 , wherein the insert is made of a plastic material. 
     
     
         19 . The refrigerant exchange arrangement according to  claim 16 , wherein at least one outer wall of the first oil-trapping chamber is made in one piece with a bottom plate. 
     
     
         20 . The refrigerant exchange arrangement according to  claim 19 , wherein a dividing wall between the first oil-trapping chamber and the second oil-trapping chamber is made in one piece with the bottom plate. 
     
     
         21 . The refrigerant exchange arrangement according to  claim 20 , wherein a covering plate is arranged on the side of the first oil-trapping chamber, which is opposite to the bottom plate, the dividing wall engaging said covering plate. 
     
     
         22 . The refrigerant exchange arrangement according to  claim 21 , wherein the insert engages the covering plate. 
     
     
         23 . The refrigerant exchange arrangement according to  claim 21 , wherein the outer wall has a fixing flange in the area of the covering plate. 
     
     
         24 . The refrigerant exchange arrangement according to  claim 16 , wherein the outlet of the second oil-trapping chamber is connected to a refrigerant collector. 
     
     
         25 . The refrigerant exchange arrangement according to  claim 24 , wherein a main pipe is connected via a first valve arrangement to the first oil-trapping chamber and via a second valve arrangement to the refrigerant collector, the main pipe having at least one outer connection. 
     
     
         26 . The refrigerant exchange arrangement according to  claim 25 , wherein the main pipe is connected to a vacuum pump via a third valve arrangement. 
     
     
         27 . The refrigerant exchange arrangement according to  claim 25 , wherein the main pipe is connected via a fourth valve arrangement to a marking substance source. 
     
     
         28 . The refrigerant exchange arrangement according to  claim 25 , wherein the main pipe is connected via a fifth valve arrangement to an oil reservoir.
