Abstract

Claims (50)

1. A method for recycling non-reusable refrigerant transport containers, comprising:

receiving at least one intact refrigerant transport container into a chamber;

sealing the chamber;

evacuating non-condensing gasses from the chamber;

puncturing the at least one intact refrigerant transport container to release residual refrigerant therein;

removing and compressing the residual refrigerant released into the chamber; and

shredding and/or compacting the refrigerant transport container.

2. The method according to claim 1 , further comprising determining a type of refrigerant content of the at least one intact refrigerant transport container.

3. The method according to claim 1 , further comprising automatically determining a type of refrigerant content of the at least one intact refrigerant transport container by reading a machine readable code associated with the refrigerant transport container.

4. The method according to claim 1 , further comprising determining that a plurality of intact refrigerant transport containers contain a single type of refrigerant composition before being received into the chamber.

5. The method according to claim 1 , further comprising determining a type of refrigerant composition in a refrigerant transport container by performing an analysis of the refrigerant.

6. The method according to claim 1 , further comprising storing the removed and compressed the residual refrigerant released into the chamber in a storage vessel in dependence on a type of refrigerant released.

7. The method according to claim 1 , further comprising determining a purity of the residual refrigerant released into the chamber, and processing the residual refrigerant in dependence on the determined purity.

8. The method according to claim 1 , further reading a bar code on at least one intact refrigerant transport container.

9. The method according to claim 8 , further comprising processing the residual refrigerant at least in dependence on the bar code on at least one intact refrigerant transport container.

16. The system according to claim 11 , further comprising a plurality of storage vessels, wherein the compressed residual refrigerant is stored in a respective storage vessel in dependence on a determined type of residual refrigerant.

17. The system according to claim 11 , further comprising at least one of an automated refrigerant analyzer and an automated refrigerant transport container identification reader, and a plurality of storage vessels, wherein the compressed residual refrigerant is selectively stored in a respective one of the storage vessels in dependence on at least one of an analysis of the residual refrigerant and an identification of the at least one refrigerant transport container.

18. The system according to claim 11 , further comprising:

an encoding associated with the intact refrigerant transport container, having a residual refrigerant content;

a database storing a record relating to the encoded intact refrigerant transport container, said database record relating at least to a deposit charged for the encoded refrigerant transport container;
