Proper ventilation in a private home - mechanical or natural?

Proper ventilation in a private house

Every room needs a properlyOrganized ventilation system - and a city apartment and a country cottage. The constant change of the entire volume of air is vital to maintain an optimum microclimate. Physiological feature of the breathing process remains unchanged: in case of insufficient ventilation of the exhaled carbon dioxide builds up every second, exceeding the permissible concentration promotes the growth of mold and pathogenic fungi, as well as adversely affect the performance of the respiratory system and hematopoiesis. As a result - lack of energy, irritability and a general weakening of the body. Ventilation in a private home (as well as in a city apartment) has to be arranged and to develop the project, in accordance with the existing rules and on the basis of calculations carried out air. Effective ventilation in a country house can be arranged in several ways, different structurally.


  • In depth process air
  • Natural ventilation in a modern country house
  • Ventilation with mechanical ventilation

In depth process air

Depending on how the organizationdistinguish natural ventilation and mechanical ventilation. In any case, the fresh air supply should be made through the living rooms and the removal of contaminated technical areas (bathrooms, toilets, kitchens, pantries). Whatever the ventilation system is not used, be sure the device vents in the inner wall of the capital premises, to avoid the possibility of freezing the channel and as a consequence of "tipping" the air flow (movement in the opposite direction) in the case of a channel device in the outer wall. Among the most polluted places on the house exhaust air is discharged to the outside air ducts.

Driving properly organized air exchange in a private house should be like this

Natural ventilation in a modern country house

Natural ventilation in a private houseIt is made by the difference between the densities of air flows inside and outside. Inflow and venting may be made formal and informal way. Since ancient times, the ventilation in a wooden house made unorganized way: the air is, even with the windows closed by infiltration and venting through small cracks in the walls and in window and door openings. On the conservation of heat in this case not to speak, as you know.

The modern system of private house ventilationhas its own characteristics, as used in the construction of new energy-efficient, but at the same steam-proof design and materials. Wall insulation with special insulating materials, the installation of sealed plastic boxes to solve the problem of drafts, but at the same time, a new problem - the lack of air flow, and as a consequence, a significant deterioration of the microclimate with all the above effects. More effective ventilation can be done in the house with his own hands. Arrange air flow in the room where installed, and windows sealed tight to the door frame entrance and interior doors can be through binding device in a window air-supply valves and special equipment door transfer grille for ventilation.

Special window for air intake valve

Supply window valve is required for the organization of air flow in areas with plastic windows

This solves the problem of lack of air andsound insulation (it comes to window and door valves that prevent the penetration of noise, but the air-permeable). Air outlet in the organization of natural ventilation in a modern house made through the hood equipped in storerooms, in the bathroom and in the kitchen. Natural ventilation system does not depend on power consumption. In the event of a power cut it runs smoothly, though her work is largely dependent on climatic and weather conditions.

Ventilation with mechanical ventilation

ventilation device in a private home maycarried out with a mechanical forcing air (this method is called mechanical ventilation). Through the use of air handling units with fans, filters and silencers made of fresh air intake, its output can be carried out in a natural way and through the use of electric suction devices.

The device of mechanical ventilation with different venting

When mechanical ventilation in the roomIt creates a positive pressure that stimulates the conclusion of contaminated air through vents to the outside. Correct ventilation is arranged in a private home provides the ability to change according to the needs of air flow parameters, because in addition to the inflow and discharge can be performed simultaneously heating, cooling, or air ionization purification.

Effective ventilation in the frame house canbe arranged only through the use of mechanical air supply system, which is due to lack of its own heat capacity at the walls. When airing the room of the house in the summer heats up very quickly in the winter just as quickly cools. So make sure the cooling air entering in summer and heating in winter to maintain the optimum temperature in the house.

Apparatus for Ventilation devices

The scheme of forced ventilation installation unit providing heating and air filtration

Forced evacuation of polluted airIt stimulates the flow of fresh: a vacuum is created, contributing to suck fresh air through windows or air inlets. This method is used when lack of effectiveness of natural draft in the summer, when the temperature difference between the outside and inside the room is small.

Often, the rational use ofenergy efficiency and ensure proper ventilation in winter and in summer is used to combine the above methods. Modern air handling unit can be, in fact, energy-saving technologies, in fact allow for air exchange with the simultaneous recovery.

As you can see, ventilation country house - hishands invested, or the forces of the invited experts, shall be designed, based on an understanding of the essence of ventilation processes, taking into account the climatic characteristics of the region and the properties of materials used in construction.
