Реферат: An apparatus (100) for recovering and depurating a cooling fluid that comprises at least one passage duct (12, 16), in particular two passage ducts (12, 16) of cooling fluid that extend entering or exiting the apparatus (100). Each passage duct (12, 16) has a distal end (13, 17) arranged to be connected to a high and/or low pressure connection (23, 27) of respective of high and low pressure lines (22, 26) of a refrigeration circuit (50) and a proximal end (14, 18) arranged to be connected to a coolant inlet/outlet fitting (32, 34) of the apparatus (100). The apparatus (100) also comprises a coolant recovery and depuration pathway (60), and a collection container (80) of accumulated cooling fluid that receives depurated cooling fluid from the recovery and depuration pathway (60). The apparatus (100) comprises a bypass pathway (90) between the collection container (80) and a bypass fitting (95, 96), configured to be connected to the distal end (13, 17) of a passage duct (12, 16) such that the flow direction of the cooling fluid drawn from the collection container (80) flows towards the recovery and depuration pathway (60). Furthermore, a program washing means is provided arranged to recirculate the cooling fluid drawn from the collection container (80) through respectively the bypass pathway (90), the passage ducts (12, 16), the recovery and depuration pathway (60) and again towards the collection container (80) in order to wash the passage ducts (12, 16) when the respective distal end (13, 17) are connected to bypass fittings (95, 96), in order to form a closed circuit with the apparatus (100). This way, residues of lubricant or other dust that normally remain in the passage ducts (12, 16) can be eliminated completely, owing to previous recovery and depuration steps.
