Proper ventilation in a private home - mechanical or natural?
- 13 Jun 05:00
Every room needs a well-organized system of ventilation - and the 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 process of breathing remains unchanged: with insufficient ventilation 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 consequence - fatigue, irritability and a general weakening of the body.Ventilation in a private home (as well as in a city apartment) must 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 organized in several ways, different structurally.
delve into the process air ↑
Depending on the way of air distinguish between the natural andmechanical ventilation.In any case, fresh air must be made through living rooms, and removal of contaminated technical areas (bathrooms, toilets, kitchen, pantry).Whatever the ventilation system was not used, be sure the device ventilation channels in the inner wall of the capital premises to avoid possible freezing of the channel, and as a consequence of "tipping" of the air flow (movement in the opposite direction) in the case of the device channel in the outer wall.Among the most polluted places of the house exhaust air through the ventilation channels is given out.
Natural ventilation in a modern country house ↑
Natural ventilation in a private home is made by the difference between the densities of air flow inside and outside.Inflow and venting can 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 and the penetration through the removal of air through small cracks in the walls, as well as in window and door openings.On the conservation of heat in this case, can not speak, as you know.
modern ventilation system of a private house has its own characteristics, as used in the construction of new energy-saving, but at the same steam-proof design and materials.Wall insulation with special insulating materials, the installation of sealed plastic boxes solves 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 of all the aforementioned consequences.More effective ventilation can be done in the house with his own hands.Arrange the air intake in the room where installed, and double-glazed windows sealed tight to the door frame entrance and interior doors can be through mandatory device in the window inlets and doors equipment special transfer unit for ventilation.
It solves the problem of lack of air and noise insulation (we are talking about window and door valves, preventing the penetration of noise, but the air was passed).Air outlet in the organization of natural ventilation in a modern house made through the hood equipped in the storerooms, in the bathroom and the kitchen.Natural ventilation does not depend on energy.In case of power failure running smoothly, though her work is largely dependent on climate and weather conditions.
ventilation with mechanical ventilation ↑
ventilation device in a private home can be done with a mechanical forcing air (this method is called mechanical ventilation).Through the use of air handling units with fans, filters and silencers made fresh air intake, its output can be carried out in a natural way and through the use of electric extractors.
device for mechanical ventilation with different venting
When mechanical ventilation in the room creates a positive pressure, stimulating the conclusion of contaminated air through vents to the outside.Correct ventilation is arranged in a private home gives the ability to change according to the needs of the airflow, because in addition to the inflow and discharge can be performed simultaneously heating, cooling, purification and ionization of air.
Effective ventilation in the frame house can be arranged only through the use of mechanical air-supply systems, due to the 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 down.Therefore, make sure the supply air cooling in summer and heating in winter to maintain the optimum temperature in the house.
Forced evacuation of contaminated air stimulates fresh: a vacuum is created, contributing to suck fresh air through windows or air inlets.This method is used in low efficiency natural draft in the summer, when the temperature difference between outside and inside the building low.
Often rational use of energy 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 - furnished with their own hands, or by the invited experts, shall be designed, based on an understanding of the processes of ventilation, taking into account the climatic characteristics of the region and the properties of materials used in construction.
