Air Handling Simulation Software

Design Ventilation Systems as Part of the Full HVAC System

Stop treating air handling as a separate calculation. With Hysopt, you model and simulate ventilation, air treatment, and hydronic systems together — giving you full visibility on performance, energy impact, and system interaction from day one.

Go beyond static calculations — simulate real ventilation performance

Ventilation design is often reduced to simplified assumptions. But real system behaviour depends on airflow dynamics, thermal conditions, and interaction with the rest of the HVAC system.

Hysopt allows you to simulate air handling systems in a physics-based environment — so you can move from rule-of-thumb design to measurable performance.

  • Visualise airflow rates and pressure drops across your duct network
  • Analyse thermal conditions using Mollier (psychrometric) diagrams
  • Evaluate system behaviour under both winter and summer design conditions

From assumptions to insight.

Automatically design and validate air handling systems

Designing AHUs and air treatment components manually is time-consuming and error-prone. Hysopt automates key design steps while keeping full transparency into the underlying physics. This allows engineers to move faster — without compromising on accuracy or control.

  • Automatically design pre-heating, cooling, and post-heating coils
  • Model humidification and full air treatment processes
  • Analyse heat recovery strategies (thermal wheel, cross-flow, mixing)

Faster design decisions.

Understand how ventilation impacts the full system

Ventilation systems don’t operate in isolation. Their behaviour directly affects heating and cooling loads, system sizing, and overall energy performance. Hysopt makes these interactions visible — allowing you to design systems that work together, not against each other.

  • Combine air systems with hydronic heating (e.g. underfloor heating)
  • Simulate CAV and VAV control strategies in a full system context
  • Quantify the impact of heat recovery on total energy demand

One integrated model.

Stop designing ventilation in isolation

Model, simulate, and optimise your full HVAC system — including ventilation and air handling — in one integrated platform.

Frequently asked questions

What can Hysopt simulate for ventilation systems?

Hysopt allows you to simulate airflow rates, pressure drops, thermal conditions, and full air handling processes. You can analyse AHU behaviour, heat recovery systems, and performance under dynamic conditions.

Can Hysopt model both air and hydronic HVAC systems together?

Yes. Hysopt combines ventilation and hydronic system modelling in one environment, allowing you to analyse system interaction, energy impact, and overall performance in a single model.

How does Hysopt support air handling unit (AHU) design?

Hysopt automates the design of key AHU components such as coils, humidifiers, and heat recovery systems. This reduces manual work while ensuring accurate, physics-based sizing.

Can I analyse heat recovery systems in Hysopt?

Yes. You can simulate and compare different heat recovery strategies — including thermal wheels, cross-flow exchangers, and mixing — and quantify their impact on system efficiency and energy use.

Who is this solution for?

HVAC engineers and consultants who want to design, validate, and optimise ventilation systems as part of the full HVAC installation — not as isolated calculations.
