Axiomatization Decision LogRegistro de Decisões
1 Identity-Giving FunctionFunção Identitária
Function class
CompressionFunction ⊑ DesignedFunction
Realized in
CompressionProcess ⊑ PlannedProcess
The compression function is identity-giving - what makes a compressor a compressor is its designed capability to compress gases by adding energy to increase pressure. This distinguishes it from pumps (liquid handling) and other fluid machinery.
2 Genus DeterminationDeterminação do Gênero
Assemblybfo:Object (BFO_0000030)
No domain-specific superclass exists in parent_candidates that is more specific than the BFO/IOF-Core roots. While 'ProcessEquipment' appears in DEXPI hierarchy, it's too broad and not ontologically well-defined. Compressors are causally unified machines with removable subcomponents (impellers, casings, bearings, seals) that can be disassembled for maintenance - fitting the Assembly pattern. They are single maintainable units with one causal boundary.
3 Differentia SpecificaDiferença Específica
∃bearerOf.CompressionFunction

An assembly that bears the designed function of compressing gases by adding energy to increase their pressure.

The compression function is the minimal differentiating condition that distinguishes compressors from all other assemblies. Assembly already provides the material artifact and designed function constraints, so only the specific compression function type is needed.
4 Necessary PartsPartes Necessárias

No necessary parts recorded.

These parts represent the minimum physical components that every compressor must have to realize its compression function, regardless of the specific compression mechanism employed.

{'type': 'GasPortion', 'count': 1, 'constraints': 'higher pressure, same composition'}
TransformationTransformação
mechanical energy added to gas to increase pressure through compression
Compressors take low-pressure gas and output the same gas at higher pressure by adding mechanical energy. The gas composition remains essentially unchanged but pressure and often temperature increase.

Pump Turbine
C2: Pump, Turbine. Incompatible process signatures: Pump handles liquids not gases, Turbine extracts energy rather than adding it, Expander decreases rather than increases gas pressure
