Abstract

A component identification system and method, including an identifier associated with a replacement component, a memory to store one or more identifiers for each previously used component corresponding to the replacement component, and a processor to compare the identifier of the replacement component with the one or more stored identifiers of each previously used component. The replacement component is acceptable where the identifier of the replacement component differs from the one or more stored identifiers of each previously used component, and the replacement component is unacceptable where the identifier of the replacement component corresponds to one or more stored identifiers of each previously used component. Prior to accepting the replacement component, one or more predetermined validation operations can be performed on the identifier of the replacement component, with the identifier being formed in a serial number or code type scheme.

Claims

1. An air conditioning (AC) recovery unit, comprising:

a display of the AC recovery unit configured to prompt a user to replace an AC filter in need of replacement;

a memory of the AC recovery unit configured to store a first list of one or more identifiers for each AC filter that was previously used in the AC recovery unit, and a second list of identifiers associated with approved replacement AC filters;

an input device of the AC recovery unit configured to receive an identifier of a replacement AC filter; and

a processor configured to compare a portion of the identifier of the replacement AC filter with the second list of identifiers associated with the approved replacement AC filters and with the first list of one or more stored identifiers for each AC filter that was previously used in the AC recovery unit, wherein

the replacement AC filter is acceptable when the portion of the identifier of the replacement AC filter differs from the one or more stored identifiers on the first list of each AC filter that was previously used in the AC recovery unit and the portion of the identifier of the replacement AC filter matches one of the identifiers stored on the second list indicating that the replacement AC filter is approved and when the replacement component is acceptable, the processor causes the accepted identifier to be stored in the first list, and

the replacement AC filter is unacceptable when the portion of the identifier of the replacement AC filter corresponds to one or more stored identifiers on the first list of each AC filter that was previously used in the AC recovery unit or the portion of the identifier of the replacement AC filter does not match one of the identifiers stored on the second list, and when the replacement component is unacceptable, the processor causes the display to indicate that the replacement AC filter is not accepted, wherein the processor is further configured to allow reentry of the identifier of the replacement AC filter when the identifier was initially entered incorrectly.

2. The air conditioning (AC) recovery unit of claim 1, wherein the processor prior to accepting the identifier of the replacement AC filter performs one or more predetermined validation operations on the identifier to determine acceptability of the replacement AC filter.

3. The air conditioning (AC) recovery unit of claim 2, wherein the identifier of the replacement AC filter includes a plurality of elements, and the second list further includes the plurality of elements,

wherein the processor determines that the replacement AC filter is acceptable when the plurality of the elements of the identifier of the replacement AC filter matches the plurality of elements on the second list, and

wherein the processor determines that the replacement AC filter is unacceptable when the plurality of the elements of the identifier of the replacement AC filter does not match the plurality of elements on the second list.

4. The air conditioning (AC) recovery unit of claim 1, wherein the identifier of the replacement AC filter includes a plurality of elements, with one or more elements of the identifier indicating a total number of replacement AC filters to be associated with a corresponding identifier.

5. The air conditioning (AC) recovery unit of claim 1, wherein the identifier comprises a serial number in a hexadecimal format.

6. The air conditioning (AC) recovery unit of claim 5, wherein the identifier of the replacement AC filter includes a plurality of elements, and the second list further includes the plurality of elements,

wherein the processor prior to accepting the identifier of the replacement AC filter performs one or more predetermined validation operations on the identifier to determine acceptability of the replacement AC filter,

wherein the processor determines that the replacement AC filter is acceptable when the plurality of the elements of the identifier of the replacement AC filter matches the plurality of elements on the second list, and

wherein the processor determines that the replacement AC filter is unacceptable when the plurality of the elements of the identifier of the replacement AC filter does not match the plurality of elements on the second list,

wherein the processor prior to accepting the identifier of the replacement AC filter performs one or more predetermined validation operations on the identifier of the replacement AC filter.

7. The air conditioning (AC) recovery unit of claim 1, wherein the identifier comprises a serial number in a hexadecimal format.

8. An Air Conditioning (AC) recovery unit, comprising:

means for displaying configured to prompt a user to replace an AC filter in need of replacement;

means for storing configured to store a first list of one or more identifiers for each AC filter that was previously used in the AC recovery unit, and a second list of a plurality of identifiers associated with approved replacement AC filters;

means for inputting into the AC recovery unit configured to receive an identifier of a replacement AC filter; and

means for comparing configured to compare a portion of the identifier of the replacement AC filter with the second list of the plurality of identifiers associated with the approved replacement AC filters and the first list of identifiers for each AC filter that was previously used in the AC recovery unit wherein;

the replacement AC filter is determined acceptable when the portion of the identifier of the replacement AC filter differs from the one or more identifiers stored on the first list for each AC filter that was previously used in the AC recovery unit and the portion of the identifier of the replacement AC filter matches one of the plurality of identifiers stored on the second list indicating that the replacement AC filter is approved and when the replacement component is acceptable, the means for comparing causes the accepted identifier to be stored in the first list, and

the replacement AC filter is determined unacceptable when the portion of the identifier of the replacement AC filter corresponds to one or more stored identifiers in the first list for each AC filter previously used in the AC recovery unit or the portion of the identifier of the replacement AC filter does not match one of the plurality of the identifiers associated with the approved replacement AC filter stored in the second list, and when the replacement component is unacceptable, the means for comparing causes the means for displaying to indicate that the replacement AC filter is not accepted, wherein the means for comparing is further configured to allow reentry of the identifier of the replacement AC filter when the identifier was initially entered incorrectly.

9. The air conditioning (AC) recovery unit of claim 8, wherein the identifier comprises a serial number in a hexadecimal format.
