Vent pipe to the hood

Today, let us consider a few original ways of ventilation, the reader learns how to extract in a private house in the absence of a central riser. Touch on common issues to be considered when installing the ducts. If in a residential apartment building ventilation pipe required for extraction, in the implementation of their own projects there is much more variation (and difficulties). Want to know how to increase the efficiency of the ventilation system in the cottage at the stage of laying communications, read on.


Ventilation ducts are known two types:

  • Metal.
  • Plastic.

In the garage is much more appropriate to apply a tube of slate. Durability and resistance to adverse conditions the material will give one hundred points handicap Shop Solutions.

Vent pipe to the hood

Ventilation for subfloor or cellar

Consider how to properly equip the hood to the cellar in the garage and the house. First you must determine the location for the inlet and outlet pipes. It needs to clearly understand the basics of the project. Thus, the outlet pipe under the ceiling begins cellar and goes to the roof without bending. Top is covered with a conical stainless steel canopy painted. How to attach a metal tube, decide on site. Choose metal corners, bolts, profiles and more.

Important to the visor was laying pipe with a margin, and the bottom edge was below the level of the upper edge of slate. This will protect the ventilation branch of precipitation, wind gusts, bullies and the occasional visitors, like birds. Acceptable close the outlet rare metal lattice. As for the height of upper edge of the roof of the house or garage, enough for half a meter, otherwise refer to aesthetic considerations. When selecting a diameter of 10 cm (from the inside) is sufficient.

Inlet and outlet pipe possible fabricate a single size of a material. This will ensure the normal functioning of the process.

Inlet pipe draws air near the floor of the first floor. When it comes to the garage, the air is taken away from the gate to avoid subfreezing fruits and vegetables in the cellar. Regarding the apartment house, you should choose a place in the cavern, where there are no pets and children. Login cover the grill. Acceptable sink to the floor and zadekorirovat architectural element. The second end of the inlet pipe down into the cellar as low as possible. Ideally well be placed at the opposite end of the duct space finding walking on the roof. The proper functioning of the ventilation holes are located at the level of half a meter from the floor.

The scheme works on the principle of natural impulses. Log in or near the garage floor of an apartment house and canopy on the roof form a closed loop with a differential pressure, due to which the air is moving in the right direction, refreshing and draining cellar. The process is not enough. Stock up on the exhaust fan and insert it into the output path. In the worst case it is permissible to do cooler system unit of a personal computer. If frost fell on in the garage cellar protect from the fresh air intake, closing the inlet ordinary cloth or polyethylene.

Pipe under the hood

Ventilation private cottage

It is quite logical for ventilation. Pipes under the hood are suitable for constructing ventilation systems. In private houses, these two branches of the total Tree closely intertwined and are mounted in parallel. Ducts and networks are close together in the loft area. It is appropriate to consider comprehensively and ventilation systems.

It mentioned that the pipes are available in two types, plastic and metal. For exhaust and ventilation of a private house builders and sellers vote for plastic:

  1. Easy to install.
  2. Have a low weight, high strength and durability.
  3. Easy to process.
  4. Low resistance to air.
  5. The good performance of noise and heat insulation, the latter is particularly important.
  6. Resistance to aggressive media and corrosion.
  7. The relatively low price.

Reliable tube for drawing

We tend to view ads skeptical resin evinces a tendency to break down into components. The process is accompanied by release of harmful substances to humans. Moreover, the polymerization will not today, but in 10 years, households have already forgotten that it was time to change the exhaust pipe of the gas boiler. To avoid difficulties and at the same time to save, be sure to output paths of networks made of plastic, and the input of metal or slate. Consider technique.

In light of this, network recycle not seem the best solution, in spite of the demonstrated high efficiency. If the window is winter, taken from outside air ventilation will be frosty, therefore, will have a fresh approach at first heat. Engineering thought is not static, it is suggested to make today an underground heat exchanger. It is known that the temperature of groundwater is 4 degrees Celsius, if it is possible to heat the intake air to a specified temperature, will help the air heating and ventilation system.

Modes of operation of air heating and ventilation

Doctors recommend to maintain the house in winter and summer temperature of 18 degrees, a maximum of 20. Do not forget about the humidity, which is placed in the range of 45 - 60%. In this case there is a sharp decline in the incidence of households, increase immunity. Underground heat exchanger will be a good decision - it is an extensive network, to construct quite amiss slate pipe for exhaust.

Immunity decreases with falling relative humidity. Mucous membranes are covered with antimicrobial mucin. While antibacterial cover protects the lungs and nasal passages, one is invulnerable. Low humidity dries out the mucus. Bacteria and viruses reach the epithelium develops airway disease.

Corrugated pipes of the exhaust system

The underground heat exchanger bursts at a depth below the soil freezing and represents a communications network with a horizontal input and output. Simply put, it's a half-dozen slate pipes laid in parallel. Inputs and outputs are combined tees and other elements. We do not recommend plastic, the explanation stated in the article. Metal disappears at once, and is slate in the soil for a long time. When this thermal conductivity is higher than that of plastic (but lower than that of metal) is perfect as the material for the underground heat exchanger.

To increase durability, it is advisable to treat lightly slate penetrating insulation. Either have to get hold of tar and bitumen to protect products from water. These materials, along with cement mortar, used for mounting. In underground heat exchanger surface has vent pipe for drawing, for example made of slate. With regard to the temperature set length of the section air taken length of 10 meters. Underground passage is branched, air velocity in each of the pipes is reduced, which assures high efficiency.

Given the constant movement of air in the system, the condensate will not become a big problem.

Construction of heating, ventilation and exhaust inside the house

First of all, you need a project. If the apartment is only corrugated pipe for exhaust can take the air above the hob and give ventilation, will not work in a private house. It is better, if the project is executed organization to create projects of private houses. In an extreme case, if not affected by load-bearing structures, distribute drawing on their own. Argued then never need.

For complex systems used tees and other connectors, connections for which the hoods have a little larger internal dimensions than that of linear ducting. It provides the convenience and ease of installation. You can do without sealant. Take the trouble to choose plastic ducts with special antistatic, or ventilation and exhaust become dust collectors. Electrical charges will accumulate in and attract solid particles from flowing stream.

for kitchen hoods plastic pipes are allowed, provided that there is available designed ventilation system. It is not necessary to combine paths systems. Extractor fan does not replace the ventilation. Possible to use kitchen lattice with special valves, then allowed to have both systems in a common hole located near the ceiling dishes, as was done in high-rise buildings. Note that each turn of the duct 90 degrees reduces the efficiency of the system by 10%, exhaust fan adding operation.
