Indoor climate & air quality
Production facilities & warehouses
Advanced CFD simulations for HVAC and filtration system design
Optimizing indoor climate and air quality for people and processes
Indoor climate and air quality in production facilities and warehouses have a major impact on both employee well-being and the reliability of industrial processes. Certain manufacturing activities can generate heat, fumes, dust, or airborne pollutants that create uncomfortable or even unsafe working conditions.
Well-designed HVAC and filtration systems are therefore essential to maintain a healthy, productive, and energy-efficient indoor environment.
Our clients
We provide our analysis and consultancy services to:
- Owners or users of production facilities or warehouses
- Engineering and consultancy firms involved in building design
- HVAC engineers responsible for HVAC or filtration system design
Our services are mainly used during the design of new halls, renovation of existing facilities or when changing the use of the facility. The main goal of our work is to validate proposed HVAC/filtration system designs, reduce energy consumption and ensure compliance with client requirements, building codes and safety standards.
Our Services
We support clients in designing, validating, and optimizing HVAC and filtration systems in industrial environments.
Our services include:
CFD Flow Simulations
Visualize airflow, temperature, and air quality for objective workplace assessments conditions and the functioning of the HVAC or filter system. If required, we propose design improvements or operational adjustments to enhance indoor climate performance.
Technical support for HVAC and filtration suppliers
We support manufacturers and suppliers of HVAC systems, filtration systems, and air handling units by validating the performance of their solutions in specific industrial environments.
CFD simulations help demonstrate how systems perform under realistic operating conditions, supporting technical sales and project development.
Wind impact analysis for rooftop HVAC equipment
Large industrial buildings often use rooftop air handling units (AHUs) and chillers. These systems interact strongly with the outdoor environment, where wind and ambient temperature can significantly influence performance.
At Actiflow, we simulate the impact of:
- Wind flow around buildings
- Ambient outdoor temperature
- Building geometry and rooftop layouts
This allows us to assess:
- HVAC system performance under realistic wind conditions
- Ventilation short-circuiting between air inlets and outlets
- Cooling efficiency of rooftop chillers
- Optimal positioning of HVAC equipment
Where necessary, we propose design solutions to prevent or mitigate short-circuiting effects.
How we work
Our primary tool for analyzing indoor climate and air quality is Computational Fluid Dynamics (CFD). When required, we complement simulations with on-site measurements to accurately characterize existing indoor conditions.
Step 1 – 3D simulation model
We first develop a detailed 3D CFD model of the facility, including:
- Building geometry
- Machinery and equipment
- Workstations and personnel
- Storage racks and other airflow obstacles
- Ventilation and filtration system components
This ensures that the simulations accurately represent the real operating environment.
Step 2 – CFD simulation and analysis
The CFD model is then used to simulate airflow and air quality inside the facility. Typical outputs include:
Cross-sectional visualizations showing:
- Airflow patterns using streamlines and vectors
- Temperature distribution throughout the building
3D visualizations showing:
- Age of air (how long air remains inside the space)
- Particle or pollutant concentrations
- Local air change rates
Step 3 – Optimization and design recommendations
Based on the simulation results, we propose design improvements and mitigation measures for the ventilation and filtration systems.
When relevant, we evaluate the impact of proposed changes by performing additional CFD simulations, allowing clients to make informed design decisions with quantified performance improvements.
