Axiomatization Decision Log
1
Identity-Giving Function
Function class
CoolingFunction
⊑ DesignedFunction
Realized in
CoolingProcess
⊑ HeatTransfer
Cooling is the identity-giving function that distinguishes coolers from other heat exchangers. A CoolingFunction specifically involves removing thermal energy from a target object or fluid to reduce its temperature, which is the essential capability that makes any heat exchanger a cooler.
2
Genus Determination
HeatExchanger
All three source definitions explicitly state that a cooler is a heat exchanger (ISO 15926: 'is a HEAT EXCHANGER', CFIHOS/POSC: 'A heat exchanger that...'). Heat exchanger is the most specific appropriate superclass and is already enriched in our ontology. The parent_candidates list includes 'HEAT EXCHANGER' from ISO 15926 which confirms this choice.
3
Necessary Parts
No necessary parts recorded (concept may be primitive at this level).
These are the minimal necessary parts inherited from heat exchanger design - surfaces for heat transfer and pathways for fluid flow. Specific cooling mechanisms (fins, coils, plates) vary by subtype.
4
Process Participation Signature ⟨I, O, T⟩
Inputs (I)
PortionOfFluid
— higher temperature process fluid
PortionOfFluid
— lower temperature cooling medium
Outputs (O)
PortionOfFluid
— cooled process fluid at reduced temperature
PortionOfFluid
— heated cooling medium
Transformation (T)
thermal energy transfer from process fluid to cooling medium
Coolers have a two-stream signature where thermal energy is transferred from a warmer process stream to a cooler utility stream, resulting in temperature reduction of the process fluid.
5
Axiom Mode Decision
Necessary + Sufficient
— modelled as a defined class
(≡, EquivalentClass). Automatic classification is
appropriate for this concept.
Disjointness Axioms
heater
C?: heater [kind_ambiguous]. Coolers and heaters have opposing thermal transformation signatures - coolers remove thermal energy while heaters add thermal energy to the process stream
Cross-Standard Observations
Excellent consistency across all three standards (ISO 15926, CFIHOS, POSC Caesar) - all define cooler as a heat exchanger intended for cooling. The definitions are nearly identical in CFIHOS and POSC Caesar, suggesting shared heritage or cross-referencing.
