Axiom type
LLM classification basis: function-based → ≡
The definitions consistently emphasize the cooling function achieved through air circulation and heat exchange. While there are constructive elements (tall structure, convection air flow), the primary identity is given by the cooling function rather than the specific physical configuration.

Identity-Giving Function
✓ done
CoolingFunction → CoolingProcess ⊑ HeatTransfer
▼
COPI-Core operation
HeatTransfer via process parent HeatTransfer
LLM rationale:
The identity-giving function is cooling - specifically removing heat from a process fluid (typically water) through heat exchange with ambient air. This is what makes a cooling tower a cooling tower rather than just any tall structure or heat exchanger.

Genus Proximus

Genus (genus proximum)
Most specific superclass — may be a domain class like "Valve" or an IOF-Core root.
BFO/IOF-Core Root
bfo:Object branch
bfo:ObjectAggregate branch
bfo:ImmaterialEntity branch
LLM rationale:
A cooling tower is a cooler: it is a heat exchanger bearing a CoolingFunction, which is exactly the definition of Cooler. The subsumption was already entailed but never declared (ODR-022 §17); naming Cooler as the genus makes it explicit and keeps the tall-tower/air-circulation differentia as what distinguishes it from other coolers.

Conditions that distinguish
Cooling Tower
from sibling classes under genus
Cooler.
Only what is not already entailed by the genus.
Differentia expression
Differentia (natural language)
LLM rationale:
The differentia captures the unique aspects: the tall tower structure that enables enhanced convective air circulation, and the use of ambient air as the cooling medium. This distinguishes it from other heat exchangers that may use different geometries or cooling media.

Necessary Parts
✓ done
no necessary parts
▼
Consider part-whole relations beyond subsumption:
hasComponentPartAtAllTimes (universal, structurally essential)
· hasComponentPartAtSomeTime (contingent, optional component)
LLM rationale:
These parts represent the minimal necessary components for any cooling tower: the tower structure itself, surfaces for heat exchange, and air flow paths for convective circulation.

Process Participation Signature ⟨I, O, T⟩
✓ done
PortionOfLiquid + PortionOfGas → PortionOfLiquid + PortionOfGas
▼
Inputs (I)
Outputs (O)
Transformation (T)
LLM rationale:
Cooling towers have a characteristic two-fluid signature: process fluid (usually water) is cooled while ambient air is heated and potentially humidified. The transformation is purely thermal - no chemical change occurs.
