SYSTEM DOCUMENTATION & REQUIREMENTS

What problem does it solve?

This Skill specializes in coil selection and thermal design, ensuring cooling/heating coils meet performance targets while optimizing hydraulics and cost.

Core Features & Use Cases

  • Coil Selection: Match capacity to loads derived from psychrometric outputs.
  • Thermal Analysis: Conduct heat transfer and flow calculations for coils.
  • Hydraulics & Performance: Evaluate water velocity, pressure drop, and circuiting.
  • Use Case: Given state/psychro and constraints, generate a coils.json with cooling/heating coil options.

Quick Start

Provide inputs from state/psychro.json and state/constraints.json to produce state/coils.json.

FAQPage Schema
How do I size cooling and heating coils for HVAC systems?

Coil sizing matches capacity to thermal loads using psychrometric inputs, face area, velocity, and flow calculations. This Skill selects coil types—chilled water, hot water, steam, or electric—and validates water velocity, pressure drops, and air-side hydraulics against performance targets to deliver optimized coil designs.

What inputs do I need to select AHU coils?

Provide psychrometric state data and design constraints including capacity requirements, available face area, allowable pressure drops, and circuiting preferences. The Skill processes these inputs to generate coil options with hydraulic performance validation and cost-efficiency optimization.

How do I evaluate pressure drop and velocity in coil selection?

Pressure drop and velocity analysis assess water-side and air-side hydraulic performance across candidate coils. The Skill calculates and validates face velocity, water velocity, and pressure drops to ensure designs meet system constraints while balancing thermal capacity and efficiency.

Can I use this for different coil types in HVAC design?

Yes. This Skill handles chilled water, hot water, steam, and electric coil types. It applies the same thermal and hydraulic selection logic across all types, delivering a structured dataset with validation checks tailored to each coil configuration.

What output does the coil selection process produce?

The Skill generates a coils.json dataset containing candidate cooling and heating coil designs with performance parameters, hydraulic properties, cost factors, and validation status. This structured output enables direct integration into AHU design workflows.
