EN 15780

Cleanliness of ventilation systems is considered important for human comfort and health, energy consumption, system service life and for cleanliness of operations or processes carried out in the ventilated area.

Benefits of a clean ventilation system

• Improved indoor air quality: A clean ventilation system helps to improve indoor air quality by removing dust, pollen, mold, and other pollutants from the air. This can lead to a number of health benefits, including reduced respiratory symptoms, improved sleep quality, and increased productivity.
• Reduced energy consumption: A clean ventilation system is more efficient than a dirty one. This is because clean ducts allow for better airflow, which reduces the need for the system to work as hard. This can lead to significant energy savings, especially in large buildings.
• Extended system life: A clean ventilation system is less likely to experience problems such as corrosion and clogging. This can extend the life of the system and reduce the need for costly repairs and replacements.
• Improved cleanliness: A clean ventilation system helps to keep the building itself clean. This is because dust and other pollutants that are removed from the air are not allowed to settle on surfaces. This can lead to a more pleasant and hygienic environment for occupants.

How to clean a ventilation system

The frequency of cleaning required for a ventilation system will vary depending on a number of factors, including the type of system, the environment in which it is operated, and the amount of use it receives. However, a good rule of thumb is to have the system cleaned at least once a year.

The cleaning process typically involves the following steps:

1. Inspection: The system is inspected to identify any areas that are particularly dirty or clogged.
2. Cleaning: The ducts and other components of the system are cleaned using a variety of methods, including brushing, vacuuming, and compressed air.
3. Disinfection: The system is disinfected to kill any bacteria or mold that may be present.
4. Inspection: The system is inspected again to ensure that it is clean and free of debris.

Additional tips for keeping your ventilation system clean:

• Change the furnace air filter every 1-3 months, or more often if you have pets or allergies.
• Use a doormat to trap dirt and dust before it enters your home.
• Vacuum and dust regularly, especially in high-traffic areas.
• Avoid smoking or burning incense in your home.
• Have your ventilation system cleaned by a professional at least once a year.

Cleaning procedures

The cleaning procedures that should be used to clean a ventilation system will vary depending on the type of system, the materials used in the system, and the level of cleanliness that is required.

In general, cleaning procedures should include the following steps:

Removal of dust and other contaminants from the ductwork.

Disinfection of the ductwork.

The removal of dust and other contaminants can be carried out using a variety of methods, including vacuuming, brushing, and washing. The disinfection of the ductwork can be carried out using a variety of methods, including the use of chemicals or heat.

Frequency of cleaning

The frequency of cleaning ventilation systems will vary depending on the type of system, the location of the system, and the level of use of the system.

In general, ventilation systems should be cleaned at least once a year. However, more frequent cleaning may be required in systems that are located in dusty or dirty environments, or in systems that are used heavily.

Conclusion

EN 15780 is an important standard that helps to ensure the cleanliness of ventilation systems in buildings. By following the guidance provided in the standard, building owners and operators can help to protect the health and comfort of occupants, and to improve the efficiency of ventilation systems.  A clean ventilation system is essential for maintaining good indoor air quality and protecting the health of occupants. By regularly cleaning the system, you can improve energy efficiency, extend the life of the system, and create a more pleasant and hygienic environment.
