Description#

Declares what a piece of cooling equipment removes heat with. An asset that satisfies this feature states its nominal cooling capacity and carries the liquid connection points its equipment class implies, so a facility thermal model can place it in a loop and compute a result that follows from the asset rather than from a template default.

The feature applies to equipment whose class declares a cooling loop — CDU and CRAH today. Which classes those are, and which connection point prefixes each one must carry, are declared per class in config/aif-equipment-<class>.json rather than in the validator. Compute rack equipment produces heat but has no cooling-specific attributes of its own, so the feature does not apply to it.

Use Cases#

Products or workflows that consume this feature:

  • StratumSim datacenter physical simulation, for steady-state facility thermal models.

  • DSX / AI Factory operational twin, for cooling capacity planning.

  • Cooling equipment manufacturers publishing datacenter assets: Vertiv, Trane, Schneider.

Thermal-Cooling-Connection-Points

Implementation

TC.002 identifies connection points by prim name under the v0.1.0 vocabulary. Under v0.2.0 the same connections are found by querying simready:connectionPoint:domain.

Version 0.2.0#

Details

Identical requirements to v0.1.0, rebased onto the v0.2.0 Connection Points vocabulary. A v0.2.0 profile selects this version so that only one version of Connection Points is pulled into the evaluation.

Pipelines#

Source file type:

  • .usd, .usda, .usdc

    • Via the AIF pipeline samples, which convert vendor CAD to USD and author the metadata.

Validation or runtime pipeline:

  • simready-validate — checks the thermal contract against the AIF-Entity profile.

  • StratumSim — consumes the declared values in a facility thermal model.

Samples#

Sample assets carrying thermal connection points, under sample_content/aif/:

  • Synthetic_CRAH — CRAH, liquid supply and return

  • Generic_CDU — CDU, facility and technology water loops at primary and secondary

  • gb300 — compute rack, liquid supply and return

Benchmarks#

  • None registered. The thermal benchmark is specified on the Connection Points capability, which owns the connection vocabulary this feature layers on.

Adapters#

None.
