If a refrigerant belongs to the 700 series in the refrigerant numbering system, it is classified as what type?

A refrigerant that belongs to the 700 series in the refrigerant numbering system is classified as inorganic. The 700 series typically includes compounds that do not contain carbon, and this classification is used to identify refrigerants that are primarily of a non-organic nature.

In the context of refrigerants, inorganic substances can include those like ammonia (R-717) and water (R-718), which do not fall within the organic hydrocarbon categories that include methane, ethane, or propane. This makes the identification straightforward; refrigerants from the 700 series are distinct from those in the other series that classify organic refrigerants by their carbon content and structure.

Thus, recognizing that the 700 series is specifically for inorganic refrigerants helps in understanding their properties and uses compared to hydrocarbon-based refrigerants categorized under different series.
