Organization of ventilation in premises: noise reduction and efficiency of work in the ventilation system

Why is proper ventilation installation important

High-quality ventilation organization directly affects people's health and comfort in the room. Incorrect installation of the ventilation system can lead to reduced efficiency, increased noise levels, additional repair costs and even disruption of the system as a whole. Ventilation should provide sufficient air exchange, maintain the necessary humidity and temperature parameters, clean the air from dust, harmful impurities and ensure comfortable breathing with oxygen.

• It is recommended to install exhaust fans with optimal power to ensure the correct flow of fresh air and maintain proper draft in the ventilation system, which is important for the microclimate in the building.

• For effective operation of the ventilation system, exhaust devices are installed, connecting them to the air ducts and installing the exhaust fan at the required height, which ensures proper pressure and air circulation in the room.

Mistake No. 1: lack of a ventilation system design

One of the common mistakes is to start installation without a clear design. Without proper planning, it is difficult to calculate the correct amount of air, determine the diameter of the air ducts and select the appropriate installations. The lack of a project often leads to poor air distribution, unnecessary processing costs and additional noise in the ventilation system.

• The lack of a ventilation system project can lead to improper organization of air ducts and insufficient fan power, which negatively affects the efficiency of ventilation and the microclimate in the premises.

• Incorrect selection or installation of exhaust fans can lead to insufficient draft or excessive noise, which worsens the comfort and efficiency of the ventilation system.

Mistake #2: Using poor-quality ventilation system materials

In order to save money, some contractors use cheap air ducts, connections or filters of questionable quality. This leads to rapid wear of elements, air leaks, ventilation problems and even the need for complete dismantling after a few years. Particular attention should be paid to the tightness of connections and the durability of materials.

• The use of poor-quality materials for the ventilation system can negatively affect the efficiency of the fan, reduce the exhaust capacity and shorten the service life of the entire system.

• The choice of materials for ventilation is of great importance, since poor-quality air ducts or exhaust devices can lead to energy consumption, reduced draft and even damage to equipment.

Mistake No. 3: incorrect location of air ducts in the ventilation system

Air ducts must be located taking into account the minimum length and number of bends. Excessive length or incorrect installation can lead to reduced air speed, increased noise and increased energy consumption. For example, excessively long exhaust ducts or 100 mm cross-sections at high loads can become a bottleneck for the airflow.

• Incorrect location of air ducts in the ventilation system affects the operation of the exhaust hood, reducing the flow of fresh air and the efficiency of heating the room.
• We recommend installing air vents and supply and exhaust ventilation devices at the optimal height to ensure correct connection and stable pressure in the system.

Mistake #4: ignoring noise and vibrations of ventilation systems

The importance of noise reduction is often forgotten. Installing systems without silencers or vibration isolation leads to mechanical and structural noise that spreads throughout the house. Noise levels above 30-35 dB can cause discomfort and sleep disturbances. To avoid problems, it is necessary to provide flexible inserts, high-quality soundproofing materials and optimal design of ventilation systems.

• Ignoring noise and vibrations in the ventilation system can lead to a decrease in comfort in the room and rapid wear of the hood and other devices.
• The optimal option is to install supply and exhaust devices at the appropriate height and control the gas pressure through a properly equipped opening.

Mistake No. 5: insufficient maintenance of ventilation and  efficiency of ventilation systems

Even the best installed system requires regular maintenance: cleaning filters, checking fasteners and fan operation. Otherwise, serious problems with ventilation can arise - from reduced performance to complete failure of the installation. Untimely maintenance can also lead to dust accumulation and contamination of ventilation shafts.

• Insufficient is maintenance of the ventilation system reduces its efficiency and can cause failure of the hood or supply and exhaust device.
• We recommend regularly checking the device installed at the appropriate height to maintain stable ventilation.

Mistake No. 6: incorrect selection of equipment, height
of the ventilation system

Mismatch of equipment with the volume of the room or type of use can lead to the fact that the ventilation system will not provide the necessary air exchange. For example, choosing a low-power hood for a large kitchen will lead to the accumulation of odors and humidity. It is important to consider the parameters — performance in m³/h, noise characteristics, energy efficiency and type of installation (supply or exhaust).

• Incorrect selection of equipment or incorrectly calculated height of the ventilation system can seriously impair the operation of the hood and the efficiency of air exchange.
• To avoid problems, we recommend that you determine in advance the optimal installation height of the device and correctly select the ventilation system for a particular room.

Mistake No. 7: lack of filtration in the rooms, basic rules

Air filtration — a mandatory stage of any modern ventilation system. Ignoring the installation of filters leads to the ingress of dust, allergens and pollutants into the room. This is especially true for supply ventilation systems, where filters trap external contaminants.

• The lack of filtration in the premises leads to the accumulation of dust, bacteria and harmful substances in the ventilation system.
• The main rule is to choose a ventilation system with high-quality filtration that will ensure the flow of clean air and protect the microclimate in the building.

Recommendations - how to avoid problems in the ventilation system to reduce noise

• Design ventilation professionally - involve specialists at the planning stage.

• Choose high-quality materials - pay attention to the certification and guarantees of manufacturers.

• Follow the basic installation rules - minimize the length and number of bends in the ducts.

• Consider the noise level — install silencers, use the correct diameters of the ducts.

• Plan regular maintenance — create a service schedule.

• Choose the right units — according to the area and functionality of the room.

• Ensure proper filtration — use high-quality filters and change them on time.
