Ventilation of the cottage: the choice of an economical solution

Dachas and country houses need high-quality and regular ventilation, regardless of the size and degree of equipment. High humidity and stale air create an environment conducive to the development of pathogens and mold. These same factors lead to damage to property and premature wear of the structure, corrosion of metal parts and inventory.

Requirements for ventilation of summer cottages

The arrangement of private houses in most cases does not allow them to be considered completely environmentally friendly, even if they are located in an area that is favorable in this regard. Extraneous unpleasant odors, stale air and lack of oxygen are the consequences of:

  • the use of plastic windows and hermetically sealed doors;
  • saturation of the atmosphere at home with harmful and toxic compounds emitted by building materials and structures, paint, floor coverings and even bedding;
  • lack of outflow of exhaust air masses due to a violation of the supply of fresh ones.

According to building codes and regulations, the air in living rooms must be completely renewed 1 time per hour. For common areas (kitchens, bathrooms), the requirements are even more serious. Neither valves for ventilation, nor even vents open in the warm season, are able to cope with the task of fully ventilating the dacha.

How are cottages ventilated?

Ventilation of the cottage: the choice of an economical solution

There are two main ways to create the required level of air exchange in suburban housing.

  1. Natural air exchange depends on weather conditions and the season, the presence, speed and direction of the wind. The high-quality operation of the draft requires a significant temperature difference between indoors and outdoors and a height difference between the holes for air intake and its output to the atmosphere of at least 3 m.
  2. The organization of forced ventilation requires the use of technological solutions and devices that ensure the movement of air masses in the room, regardless of external conditions and the height of the pipes.

Extraction of exhaust air with fans and ducts

The simplest option for organizing forced ventilation is to use a fan for an exhaust duct. It helps to remove exhaust air from the premises, subject to the natural influx of fresh atmospheric masses through gaps, cracks, ajar windows and vents.

In bathrooms and kitchens, such devices can be used on an occasional basis, equipped with motion sensors or connected to a light switch. At the construction stage, it is possible to lay a more rational mechanism for ventilating the dacha, especially after winter, by installing a single exhaust fan in the utility room or attic. Structurally, for the centralization of the hood, a centrifugal scheme is used, suitable for processing air flows from several pipes.

Such systems do a good job of airing the dacha in spring and summer, but in winter the cold air coming from the street becomes a source of drafts and can lead to cooling of the rooms and significant heat loss. They are also not designed to get rid of dust and odors.

Supply and exhaust systems

In order to ensure full air exchange in the premises and get rid of the disadvantages associated with the use of imperfect exhaust ventilation, it is preferable to install a modern system of supply and exhaust ventilation. The equipment presented on the market also allows you to heat the supplied air, if necessary, and clean it from impurities and dust.

The removal of exhaust air masses is carried out in the usual way with the help of fans. The air supply unit is mounted outside the house or in the attic, the placement of pipes should be provided for at the design stage of the building. The operation of the supply and exhaust equipment must be carried out synchronously, otherwise, the pressure in the rooms will be unstable.

Specialized ventilation equipment requires the allocation of considerable sums for its purchase and installation, as well as an uninterrupted connection to the power supply network. Reducing the cost of heating the incoming air can be achieved by using rotary heat exchangers or plate cross-flow heat exchangers. In general, such systems most often turn out to be the most expensive options used to ventilate summer cottages and are not suitable for small houses, change houses and trailers.

The use of air collectors allows you to solve several issues related to the arrangement of a forced ventilation system at once.

  1. The functioning of the ventilation system based on solar panels does not depend on a stable supply of electricity and does not overload the network.
  2. The airing of the dacha is carried out automatically and does not require constant monitoring of the operation of the equipment.
  3. Air solar collectors are fireproof.
  4. The cost of the equipment is relatively low, besides, the money spent is quickly paid off by saving on electricity bills.
  5. The device operates year-round, allowing you to extend the life of the building and prevent its early wear, as well as damage to property.
  6. Installation of air collectors is simple and does not require registration of permits in state supervisory authorities.

Dachas and country houses need high-quality and regular ventilation, regardless of the size and degree of equipment. High humidity and stale air create an environment conducive to the development of pathogens and mold. These same factors lead to damage to property and premature wear of the structure, corrosion of metal parts and inventory.
