SYSTEM DOCUMENTATION & REQUIREMENTS

What problem does it solve?

This Skill performs high-level AHU configuration and sizing, establishing the preliminary arrangement, cabinet dimensions, and sections for downstream engineering tasks.

Core Features & Use Cases

  • Configuration Selection: Determine horizontal/vertical/penthouse configurations and fan arrangements.
  • Section Layout: Plan section sequence for draw-through or blow-through configurations.
  • Preliminary Sizing: Calculate face areas, cabinet dimensions, and section lengths.
  • Use Case: Produce a concept.json with initial design decisions to guide subsequent coil, airflow, and QA steps.

Quick Start

Provide customer requirements and constraints to output state/concept.json.

FAQPage Schema
How do I configure and size an air handling unit for my HVAC project?

Configure and size air handling units by selecting horizontal, vertical, or penthouse configurations, planning section layout, and calculating cabinet dimensions to meet performance and energy constraints. This Skill outputs a concept.json with preliminary design decisions for downstream engineering tasks.

What does AHU design configuration involve?

AHU design configuration determines fan arrangement, section sequence for draw-through or blow-through airflow, face velocity validation, and access provisions. It establishes the cabinet dimensions and preliminary section arrangement before detailed coil and airflow engineering.

Can I use this for commercial, industrial, and healthcare HVAC projects?

Yes, this Skill applies to commercial, industrial, and healthcare HVAC projects. It handles configuration selection, section layout planning, and preliminary sizing tailored to performance, energy, and space constraints across these sectors.

What input data does the AHU sizing process require?

Provide customer requirements and constraints via state/request.json and state/constraints.json. The Skill reads these inputs and outputs state/concept.json containing design decisions, cabinet dimensions, sections, and design notes for subsequent engineering steps.

How does AHU cabinet sizing work with space constraints?

Preliminary sizing calculates face areas and cabinet dimensions while validating envelope fit and access provisions against space constraints. The output ensures the AHU arrangement meets geometric and operational requirements before detailed design.

What happens after AHU configuration is complete?

After configuration, the concept.json guides downstream tasks including coil selection, airflow analysis, and quality assurance validation. Subsequent agents use the preliminary design decisions, section arrangement, and cabinet dimensions for detailed engineering.
