Note:
The channel data is representative of the IR signal detected. It is not representative of
any specific refrigerant, is not measured as a % by weight and only indicates an optical response.
Channel data should be used as a reference to help improve accuracy of Identified Refrigerants.
Diluted Refrigerant:
Refrigerant analyzed and found to be diluted will have the expected base components with
any level of Air present in the sample. This refrigerant would have a yellow screen to indicate
the Air has contaminated the sample
(Figure 17)
. Air can be removed from refrigerant but
can be harmful if present inside a system. Air left in a system can alter P/T curves, lead to
moisture accumulation and acid buildup. Both will cause a system to work inefficiently and
lead to possible system failure. In this example, Diluted R-410A is contaminated with Air.
Identified Refrigerant:
Refrigerant analyzed and found to be an identified gas will not display composition of the
refrigerant. Instead, the analyzer confirms the refrigerant matches the expected identified
gas with a green screen and provides channel data to reference as a “fingerprint” model of
that gas (
Figure 18)
. In this example, R-1234yf is Identified as R-1234yf. The channel output
provides a “fingerprint” of this gas. This channel data can be documented and used for future
cross reference to confirm the quality of the identified refrigerant.
