Manufacturer Data and Calculation Models in AHU Selection

AHU selection results depend on their inputs, data sources and calculation methods. A supplier library, a catalog table and an engineering model can serve different purposes; each needs a defined operating range and validation appropriate to the project.

Ask for the source and its limits

Identify the supplier, product range and version. Check the reference conditions and supported input ranges. Clarify whether the software calls a supplier library, reads catalog values, interpolates between points or uses a separate model.

A manufacturer's name alone does not establish certification, endorsement or a guarantee for a finished unit. Confirm the scope of any certification with its issuer and the responsible manufacturer.

Compare like with like

Use the same airflow, temperature, pressure basis and selected product in both the proposed workflow and the reference selection. Compare several representative operating points, including points near the permitted limits. Differences should be explained, not hidden by rounding.

Review conversions and missing information

Check units at each data boundary. A pressure stated in pascals is different from a value in kilopascals; a capacity in watts is different from a value in kilowatts. Incomplete data should be identifiable in the review process.

Agree project acceptance criteria

For AirSelect3D, discuss the required suppliers and product ranges during scoping. Integrations include Camfil, Ziehl-Abegg, Kruger, Nicotra, Comefri, Friterm, Hoval and Östberg, subject to the agreed scope and supplier permissions. Validate the required selections against reference data before using the workflow for customer commitments.
