Embodiment Construction

[0028] attached figure 1 Shown is a schematic diagram of a refrigerant replacement device 1 that can be used to remove refrigerant from a schematically shown air conditioner 2 , process the refrigerant, and reintroduce it into the air conditioner 2 .

[0029] The refrigerant replacement device has a main line 3 connected to two or more external joints 4, 5. The connection to the air conditioner 2 is established through the external connections 4 , 5 and the valves 4 a , 5 a corresponding to the external connections 4 , 5 . The main line 3 is connected to the oil separation unit 7 via a first valve arrangement 6 . The valve arrangement has an electrically operable valve 8 , eg a solenoid valve, and a non-return valve 9 which opens towards the oil separation unit 7 .

[0030] The oil separation unit 7 has a first oil separation chamber 10 and a second oil separation chamber 11 . The first oil separation chamber 10 is connected to the main line 3 via the first valve device 6 ....

Abstract

A refrigerant exchange arrangement is claimed with a first oil-trapping chamber (10) and a second oil-trapping chamber (11). A refrigerant exchange arrangement of simple construction is to be realized. For this purpose, the second oil-trapping chamber (11) is disposed within the first oil-trapping chamber.

Description

technical field [0001] The invention relates to a refrigerant replacement device, which has a first oil separation chamber and a second oil separation chamber. Background technique [0002] The present invention will be described below in conjunction with the replacement of refrigerants in automotive air conditioners. The present invention can also be used in other applications with similar problems. [0003] When maintaining a car air conditioner, the refrigerant needs to be replaced in most cases. The concept of "replacement" does not necessarily refer to the complete replacement of the refrigerant contained in the air conditioner with a new refrigerant. In most cases it is sufficient to dehydrate the refrigerant and / or replace the oil contained in the refrigerant with new oil. In addition, of course, during this type of maintenance, it should be checked whether some parts of the air conditioner are to be replaced, and whether the air conditioner is sealed. [0004] Wh...
