What is Mechanical Ventilation Control?
Mechanical ventilation control (VMC) is a system that improves indoor air quality by exchanging stale air with fresh air, reducing the need for traditional window opening. This approach saves energy compared to using classical windows.
Why is Air Exchange Important?
Proper air exchange is crucial for maintaining comfort in enclosed spaces. Regular airflow helps prevent mold growth, regulates humidity and condensation, and reduces the risk of respiratory problems such as asthma, allergies, and headaches. When natural ventilation is insufficient, it’s essential to use mechanical systems like VMC.
How Does Mechanical Ventilation Control Work?
Mechanical ventilation control systems ensure constant airflow renewal, regardless of external weather conditions. These systems are designed to work autonomously, without manual intervention.
Types of Mechanical Ventilation Control Systems
There are two primary types of VMC systems:
- Autoregulable VMC: This continuous system regulates airflow based on demand.
- Igroregolable VMC: This system uses sensors to adjust airflow according to humidity levels, reducing unnecessary ventilation and energy consumption.
Benefits of Mechanical Ventilation Control
VMC systems offer several advantages:
- Constant airflow renewal
- Energy efficiency
- Reduced risk of respiratory problems
- Improved indoor air quality
Designing a VMC System
Proper sizing is crucial for achieving optimal performance. Factors such as lifestyle, infiltration rates, and building design influence the required ventilation rate.
Principles of Ventilation Design
1. Calculate the required ventilation rate
2. Consider factors like infiltration rates and airflow patterns
Recuperation of Heat in VMC Systems
Integrating heat recovery into VMC systems can increase efficiency by up to 90%. This technology reduces energy consumption and makes installation easier.
Costs of Mechanical Ventilation Control Systems
Prices vary widely depending on the system type, size, and features. A basic VMC system for a single room costs around €800. Larger homes or those requiring additional features may incur higher expenses, up to €7,000.
Key Features and Considerations
When selecting a VMC system, consider:
- Recuperation of heat
- Air filtration
- Humidity control
- System size and capacity
Choosing the Right VMC System for Your Needs
By understanding the benefits and principles of mechanical ventilation control, you can make an informed decision when selecting a system that meets your specific requirements.
Case Studies
