Controlled Mechanical Ventilation (CMV) is a ventilation system used in buildings to ensure adequate air exchange.

This system controls and regulates the airflow inside the building, expelling stale air and introducing fresh air from outside. CMV improves air quality, reduces moisture buildup, odors, pollutants, and allergens. It can be used in both residential and commercial environments, helping to create a healthy and comfortable environment. CMV consists of fans and ducts that regulate airflow, and it can be either a single-flow or a double-flow system.

CMV regulates the airflow based on the needs of the building and its occupants and can be equipped with sensors to monitor air quality and automatically adjust the flow. Some CMV systems can also recover the heat from the expelled air to preheat or pre-cool the fresh air. The advantages of CMV include improving indoor air quality, reducing moisture, and dispersing odors and pollutants. Additionally, it helps reduce condensation on windows and improve the energy efficiency of the building. Regular maintenance of the CMV is important to ensure its proper functioning.

Here are some key points to consider:

  • Operation of CMV: CMV uses fans and ducts to regulate airflow inside buildings. Stale air is expelled from humid areas, such as bathrooms and kitchens, while fresh air is introduced through air intakes in the main rooms.
  • Types of CMV: There are different types of CMV, including single-flow and double-flow CMV. Single-flow CMV only expels stale air and introduces fresh air, while double-flow CMV uses two separate flows to expel stale air and draw in fresh air from outside.
  • Airflow control: CMV regulates airflow based on the needs of the building and its occupants. It can be equipped with sensors to monitor air quality, temperature, and humidity, allowing it to automatically adjust airflow based on desired levels.
  • Heat recovery: Some CMV systems can be connected to a heat recovery system. This allows preheating or pre-cooling of fresh air using the heat from the expelled air, helping to improve the building’s energy efficiency.
  • Advantages of CMV: CMV offers several advantages, including improving indoor air quality, reducing moisture, and dispersing odors and pollutants. Additionally, it helps reduce condensation on windows and improves energy efficiency by reducing the need to open windows for ventilation.
  • CMV maintenance: To ensure optimal operation, CMV requires regular maintenance. This includes cleaning filters and ducts, as well as checking the proper functioning of fans and sensors.

CMV is particularly important in well-insulated and energy-efficient buildings, as well as in living spaces recently rehabilitated from wall moisture problems and infrequently used, insufficiently ventilated homes, where air could otherwise become trapped and cause moisture, mold, condensation, and poor air quality. CMV helps ensure a healthy and comfortable indoor environment, contributing to the well-being of occupants and the reduction of health risks.

In conclusion, CMV is a system that helps ensure a healthy, comfortable, and energy-efficient environment in buildings.
