Modern ventilation systems of a private house supply a stream of fresh air to the rooms and distribute it efficiently throughout the day. Supply ventilation filters the air supplied to the house; a conventional duct system is used for operation. Along with this, the installation ensures that the house receives clean and moist air at a temperature that is comfortable for the person.
Varieties of home air renewal systems
As a system for providing access to fresh air in a private house, you can use one of three options:
- natural ventilation;
- forced ventilation;
- mixed type ventilation system - natural ventilation together with a device where a hood is used.
Each of these options has its own advantages and disadvantages, so the choice is made by each owner of a private house, depending on their own wishes and some other factors.
Varieties of air handling units
The current supply ventilation systems can be divided into two main categories:
- natural;
- forced.
The intake of air in the home, which is due to the temperature difference inside and outside or as a result of exposure to wind, is a supply of natural ventilation in the room.
In the first case, the movement of the air mixture occurs as a result of heating the ventilation ducts. In the second case, the air flows move as a result of the influence of the wind, which directs the air into the room.
The advantage of operating this type of system is the lack of the need to install expensive equipment. In such a system, no moving elements are used - electric motors, fans and the like, which have a limited life. Thanks to this, the system continues to operate even when the power is cut off.
The use of forced ventilation is required when a constant active air exchange is necessary in the house.
Compulsory systems are able to supply heated or cooled air to the premises, which is especially important in cold and hot seasons. In addition, the supplied mixture before entering the house is completely cleaned of dust and various impurities. It should also be noted that such installations provide a uniform distribution of air throughout the house, which is an effective method of dealing with condensate on the windows.
This type of ventilation equipment is usually used in production and in office premises where it is necessary to ensure active air exchange all day. But in private homes, the use of air handling units is not at all uncommon.
What is a forced ventilation
This is the installation that provides the house with a clean air mixture; it consists of: air supply unit, grilles for channels and air ducts. The most stitched installation consists of:
- air filter;
- shut-off valve;
- a heater that makes the air mixture warm in winter;
- a fan;
- silencer, which ensures quiet operation of the device.
When such a device is used for a private house, fresh air mixture is supplied to the living quarters, and the exhaust air is drawn through the ventilation ducts of the bathroom, kitchen and bathroom. For the normal functioning of the system in the house, intake grilles must be installed on the doors.
It is clear that hoping only for natural ventilation in a private house is not rational, as a result of which the installation of such a system will ensure high-quality air exchange in the home by constantly supplying clean air to it.
Supply units of different power levels, which can easily be found on the modern market, are able to provide service for both compact and large-sized rooms. As a result of all this, all residents of the house receive air that is completely safe for their health, which is completely devoid of any harmful impurities, dust and unpleasant odors.
Thus, the supply ventilation in the house is a reliable guarantee of high-quality air exchange at a low level of electric energy consumption.
Main components and principle of operation
Among the main components of the ventilation type ventilation system are the following:
- Air valve. Due to its presence, the air mixture enters the house only if the device is turned on.
- A filter element that provides air purification from various odors, dust particles and other contaminants. The set of filters used and their quality determine the level of purification of the air mixture.
- Heater. Thanks to his work in the winter, the heated mixture will come into the room, and not cold. Such an element may be water or electric.
- One of the most important elements is the fan, which provides air supply to the house. This is carried out as a result of the pressure that he creates in the system.
- The silencer provides a reduction in the noise level that occurs during the operation of the system.
Therefore, the main purpose of using the air handling unit is the forced supply to the house of cleaned air of various toxins and dust, which is heated to the temperature of the required level.
The air mixture before entering the home lends itself to various degrees of purification from various pollutants. As for the temperature of the injected mixture, the supply ventilation of the method of both heating it and cooling to a suitable temperature - it all depends on the conditions under which the ventilation works.
It is precisely because of this that this type of air exchange system is very popular in private houses of various types, where it is important to provide conditions comfortable for a person. It is important to remember that using this type of device is allowed only in rooms without dampness, excess moisture and gas formations. Therefore, forced ventilation is not intended for bathrooms, kitchens, showers.
During the operation of such an air-cleaning system, increased pressure is created, which causes the exhaust air mixture to leave the house through the cracks of windows and doors, as well as free ventilation ducts. Thus, air is vented naturally.
Disadvantages of using a supply unit
Despite the significant number of advantages of using an air supply unit in private homes, it also has some disadvantages that are most noticeable when designing and installing the system in places where there is dense residential development. Such problems are associated with the lack of space for the normal installation of such a device, since it requires a certain free space to fulfill all the necessary requirements and standards.
Often the installation of this type of ventilation during its operation creates a certain noise, which causes certain inconvenience for residents.To qualitatively solve this problem, the use of vibration-proofing and soundproofing materials is required. However, the implementation of such work involves additional material costs.
Installation for rooms with plastic windows
As already noted, the air is vented from the room where the ventilation is installed, naturally. In the same private houses where hermetic plastic windows are used, such air exhaust is not possible.
For such cases, air handling units are designed. Their main difference from conventional air handling units is that they are able to provide both an influx of fresh air and an exhaust outlet. In addition, such systems also control the humidity in the room well.
Most often, air handling units are used in spacious public areas, however, compact installations for private houses that are easy to install can be easily found. You can mount them both from the outside of the room, and inside, making for this two through holes in the wall.
Such installations by means of recovery provide heating of the air mixture entering the house. This method involves reducing material costs for heating. In addition to recovery, air heating can be carried out by a conventional heater - water or electric.
In addition to the main components of the system, which has both a supply and a supply and exhaust device, the latter differs in some additional elements. Among them:
Ventilation grille. It is located on the outside of the room and prevents foreign objects from getting into the duct.
Air distribution devices that control the outflow and flow of air. There are a large number of installations of this type; all of them are characterized by their design and operational parameters.
A regulator that controls the speed of the fan. Thanks to this, the amount of air that is supplied to the room is regulated.
The regulator allowing to establish air temperature, comfortable for the person.
Temperature sensor that works with the regulator. It provides accurate maintenance of the required temperature level inside the home.
Thus, supply-type ventilation is a reliable and proven way to ensure a constant supply of clean air mixture to the house, which always has a comfortable temperature.
