Main types of ventilation systems: ventilation system, ventilation systems, types of ventilation, types of ventilation

In short, ventilation – is a system that is divided into three main types: exhaust, supply, supply-exhaust ventilation, including supply-exhaust installation and duct ventilation.

• Natural ventilation
• Mechanical ventilation
• Mixed (combined) ventilation

Each of these types of ventilation systems has its own characteristics, advantages and disadvantages. Let's take a closer look. Understanding the differences will help you choose the ventilation system that is best suited for you. This is the basis for proper ventilation design and further operation of the ventilation system.

It is also worth noting that the choice of a specific type of ventilation depends on many factors - climate, type of building, purpose of the premises and the owner's budget. Each of these aspects affects the efficiency and convenience of the ventilation system. Therefore, a comprehensive approach - the key to success in creating a comfortable microclimate in the room area.

Natural ventilation: how it works and where it is used in the room ventilation system

Natural ventilation — is the simplest and at the same time the oldest device for providing fresh air supply ventilation and removing exhaust air, odors, moisture and polluted air. Its operation is based on natural phenomena — temperature and pressure differences, wind and even air movement through open doors, windows or ventilation ducts, air ducts. It does not require complex equipment, valves or fans and is as environmentally friendly as possible. However, its effectiveness strongly depends on external conditions and the design of the building.

Natural ventilation usually works like this: warm air in the room rises and is removed through ventilation shafts, and fresh, colder air enters from the outside through special openings or open windows. This simple principle was the basis of ventilation in old buildings hundreds of years ago. It is now used where a high level of air control is not required. with it provides minimal operating costs.

Where is natural ventilation used, ventilation system, type of ventilation, types of ventilation?

It can often be found in old multi-storey buildings, country houses, cottages, garages and other premises where there is no possibility or need to install complex ventilation systems, forced ventilation, duct ventilation or local ventilation. It is suitable for premises with a small area and not too strict requirements for air quality. This type of ventilation allows you to reduce installation and maintenance costs. At the same time, it creates a natural microclimate without unnecessary noise and energy consumption.

Advantages of natural ventilation in ventilation systems, supply and exhaust ventilation, supply ventilation

• No electricity required — economy and simplicity.
• Easy to install without complicated installation work.
• Minimal maintenance costs.

This type of ventilation is ideal for those who value naturalness and minimalism. However, its effectiveness depends on the correct design of the building and the location of the ventilation holes.

Disadvantages of natural ventilation in ventilation systems, ventilation system

• High dependence on weather conditions — on a windless day or in winter, it works worse.
• Poorly adjustable — it is difficult to control how much air enters and exits.
• In sealed modern buildings, it may not provide the necessary air exchange.

Due to these disadvantages, natural ventilation does not always meet modern standards of comfort and safety. Therefore, in many cases it is supplemented or replaced by mechanical systems.

Thus, natural ventilation is a basic way of providing fresh air, which is especially suitable where it is not possible to install complex equipment or there is a desire to minimize costs.

Mechanical ventilation: types and principle of operation in ventilation systems, classification of ventilation systems

When natural ventilation becomes insufficient, a mechanical ventilation system comes to the rescue. These are modern systems where fans, supply and exhaust units, valves and other equipment are installed, which forced ventilation forcibly "drives" air in and out. They work regardless of weather, temperature or wind, so they provide stable and controlled air exchange.

Such systems, in particular duct ventilation, supply ventilation, local ventilation using air ducts, are especially important in offices, apartments and industrial premises with increased requirements for air quality.

Thanks to them, it is possible to maintain an optimal microclimate at any time of the year. Mechanical ventilation removes polluted air and provides an influx of fresh air, which significantly improves the quality of the air in the room.

Main types of mechanical ventilation, types of ventilation, types of ventilation, ventilation system

• Exhaust ventilation:It removes exhaust air from the premises. Used in bathrooms, kitchens and other places with high humidity or odors.
• Supply-exhaust ventilation:Provides simultaneous supply of fresh air and exhaust of exhaust air. This is a balanced system that provides a comfortable microclimate.
• Ventilation with heat recovery:The smartest and most economical system. It does not just change the air, but returns heat from the exhaust air to the room, which allows you to significantly reduce heating costs.

Each type has its own purpose and should be chosen based on the specific needs of the building. It is also important to consider the noise level that the system can create and its energy consumption.

Advantages of mechanical ventilation, supply and exhaust ventilation system, ventilation, fans, air ducts

• Works stably and regardless of external conditions.
• Ability to precisely control and regulate air exchange.
• No drafts and ensuring a comfortable climate.
• Ability to filter air from dust, allergens and contaminants.

These advantages make mechanical ventilation indispensable in modern premises with high requirements for air quality. It also increases safety by eliminating the risks of accumulation of harmful gases.

Disadvantages of mechanical ventilation in ventilation systems, types of ventilation systems

• Requires electricity — hence, electricity costs.
• Regular maintenance is required, filter replacement.
• More complex and expensive installation compared to natural ventilation.

It is worth considering that without regular maintenance, the system may work less efficiently. Also, the cost of installation and operation can be quite high, which must be foreseen in the budget.

Mechanical ventilation — this is already It is a complex solution that is suitable for those who value stability and comfort in any weather and season. It is indispensable in modern buildings where tightness does not allow natural ventilation to work effectively.

Recuperative ventilation systems

Recuperation — is a step forward in energy efficiency of ventilation. If you want not just fresh air, but also savings on heating, this is your choice. The recovery system uses a special recuperator – it is a heat exchanger that takes heat from the exhaust air and transfers it to the fresh air coming in from the outside. This approach significantly reduces heat loss and makes heating more rational. This is especially important in regions with a cold climate, where heating costs can be significant.

This means that in winter you will not have to heat the street through open ventilation ducts, and in summer — lose the coolness of the air conditioner. Recuperators help to significantly reduce energy consumption, maintaining a comfortable temperature in the room. They also help to improve air quality due to filters and humidification. Modern models are equipped with automation, which allows you to control the ventilation system as efficiently as possible, providing for the presence of various types of ventilation, including supply and exhaust systems and local exhaust ventilation.

Recuperative ventilation systems, ventilation system, classification of ventilation systems

• High energy efficiency.
• The ability to filter the air from dust, pollen, bacteria.
• Modern models are equipped with humidity and temperature sensors, and control via smartphone.
• Improve air quality and reduce heating/air conditioning costs.

Recuperators — This is not only saving money, but also increasing comfort, which is especially important for families with children and people with allergies. Thanks to modern technologies, they can be easily integrated into a «smart home» for maximum convenience. The classification of ventilation systems provides for the presence of different types of ventilation: natural, general exchange ventilation, supply and exhaust systems, as well as exhaust ventilation using duct devices, valves and ducts.

Given the rapid development of technology, recuperative systems are becoming more accessible and easier to operate, which makes them the best choice for those who want to have an environmentally safe and economical home of your house or apartment.

Mixed (combined) ventilation: what it is and when it is used in ventilation systems, types of ventilation

As the name implies, mixed ventilation — is a combination of natural and mechanical systems. This approach is often used to combine the advantages of both methods and minimize their disadvantages. For example, in the cold season, you can use mechanical ventilation with recuperation, and in the warm season - natural - to save on electricity. This allows you to adapt the supply and exhaust ventilation system to different operating conditions and increases its overall efficiency. Mixed ventilation creates a balance between comfort and energy efficiency.

Mixed ventilation is popular in office premises, shopping centers, large residential buildings and production facilities, where it is important to have flexibility and the ability to adapt to changes in climate and load. It also reduces the risk of accidents and unforeseen failures in work. Due to the combined approach, you can optimize electricity costs and ensure a stable microclimate. This is a solution for those who value innovation and reliability at the same time.
