Aerodynamics for R&D
HVAC systems
Analysis and design of high-efficiency HVAC systems
Optimizing housing and system lay-out for minimum energy consumption
An HVAC system typically consists of a housing that contains key components such as a fan, heat exchanger, filters, and heating or cooling elements. The performance and energy efficiency of the system strongly depend on the internal layout and the aerodynamic design of the housing.
We help our clients minimize pressure drop across the system and select the most suitable components. By optimizing the housing geometry and defining the most effective system configuration for a given airflow rate, we ensure optimal performance within the physical design constraints.
Our clients
We support manufacturers of HVAC systems (Heating, Ventilation and Air Conditioning) in the development of high-efficiency air handling solutions for a wide range of applications. In some cases, we also collaborate with suppliers or end users to determine the best HVAC configuration for a specific building, room, or industrial environment. For more information about optimizing indoor environments, please visit our page on Indoor Climate and Air Quality.
Our clients range from small and medium-sized manufacturers with limited R&D capacity to large international companies with extensive engineering teams. Depending on your needs, we can:
- Support your R&D department with specialized expertise in airflow simulation and measurement
- Perform independent analyses of HVAC performance
- Design complete HVAC systems from concept to validation
Our services
Our services range from airflow analysis to the complete design and optimization of HVAC systems. By measuring or simulating airflow and heat transfer inside HVAC units, we provide detailed insight into system behavior and efficiency. In many cases, the key challenge is to reduce pressure drops, which directly affects energy consumption and operating costs. Pressure drop is influenced by factors such as:
- Positioning of components inside the housing
- Housing geometry and internal aerodynamics
- Airflow rate through the system
- Design of air inlets and outlets
- Selection of fans, filters, and heat exchangers
Depending on the available design freedom, we optimize these parameters to achieve minimum pressure drop and maximum energy efficiency.
Our expertise can be applied during new product development, but also when performance issues occur in existing HVAC systems In such cases, we identify the root cause of the problem, propose targeted design improvements, validate solutions using CFD simulations and/or measurements and support implementation to ensure performance targets are achieved.
When involved in the full system design process, we can also assist with the selection and sourcing of components, including fans, heating elements, filters, etc.
How we work
Our primary tool for HVAC system analysis and design is CFD simulation (Computational Fluid Dynamics). CFD allows us to visualize airflow patterns, pressure distribution, and heat transfer phenomena inside complex geometries.
Simulation results enable us to:
- Understand system performance in detail
- Compare design alternatives
- Predict energy efficiency
- Detect potential issues early in the design process
In selected projects, we also perform measurements. Measurement data can be used as input for simulations or to validate simulation results, ensuring a high level of reliability.
Our projects typically follow an iterative engineering process:
Analysis → Concept development → 3D modelling → CFD simulation → Validation → Optimization
The number of iterations depends on system complexity. Thanks to our extensive experience in HVAC development, we are able to achieve optimal results efficiently, minimizing both development time and cost.
