Comfortable microclimate indoors without drafts it is possible, having established the plenum ventilation. Valves of the plenum ventilation can be both window, and wall execution. The simple device and simple service in combination with available cost, have made this adaptation demanded in owner-occupied dwellings and city apartments. Operation of the incoming valve does not require the electric power, the natural movement of air masses is used here.
Can tell formation of condensate that the room is insufficiently aired at windows, it is especially noticeable during the cold period of season.
The modern technologies applied in construction create the high level of tightness of window and door assemblies therefore indoors at insufficient ventilation the close air can accumulate, amplify humidity that the discomfort in turn brings and leads to distribution of harmful microorganisms.
Airing by means of opening of shutter creates strong air flow, drafts that also does not bring benefit. The most optimal variant is mounting of the valve of the plenum ventilation in wall or plastic window.
Device of the valve of the plenum ventilation
Today there are several similar systems, but the operation principle at them is identical. The following elements enter the device of the valve of the plenum ventilation:
- heat-insulated pipe;
- protective screen with mosquito grid;
- the valve with the regulator.
The difference in exterior and design of parts depends on type and installation site of the valve (on wall or on window).
The principle of operation of this device idle time, at difference of indoor temperature and on the street arises air pressure difference that the valve of the forced-air and exhaust device puts in action.
Thanks to the simple device, the valve can serve long time, at the simplest leaving:
- Cleaning of grid;
- Replacement of mosquito grid.
Features of work of systems of the plenum ventilation
The main task of vent systems of the incoming type is providing the room with continuous inflow of fresh air and removal of the exhaust air saturated with carbonic acid and vapors of moisture.
The arriving air, passing through delivery pipe, previously it is cleaned from garbage and dust. At the same time, unlike windows or window leaves, via the ventilation system foreign sounds do not get.
Dopolnitelya thermal insulation, keeps stable air temperature in the channel of pipe. It is possible to regulate force of ventilating stream special blinds at the output of the channel to the room.
If the wall valve is located over heating radiator, then the air in the winter arriving heats up previously the rising thermal waves.
Installation of the valve of the plenum ventilation demands certain skills, the special equipment and experience of carrying out these works.
Mounting of ventklapan
Before installation of the valve, the master deletes part of the basis (walls or windows) where special consolidation, layer the employee directly for installation works will be placed subsequently.
The plenum ventilation belongs to passive type, it does not require the electric power, the air pressure difference on the street and indoors is used. This technology is energy saving, economic and eco-friendly.
After the correct installation of ventilation device, fresh air will begin to drag on independently to the room, and fulfilled to be thrown out through exhaust ventkanala. This valve works not only for inflow of fresh air, but also for extract.
Important! Naturally, circulation of air streams is possible only at street temperature no more than 5 degrees. At higher rates it is necessary to involve mechanical ventilation on power supply.
Types of valves of the plenum ventilation
There are only two types of the ventilation valves intended for installation in premises – wall and window.
The valve wall is the pipe equipped with thermal insulation, protective screen and directly the valve with possibility of adjustment of the arriving air mix.
Various modifications of devices can have both manual, and automatic way of adjustment. If the automatic incoming valve is installed, then the following processes will be regulated:
- air pollution;
- the increased humidity;
- non-uniform pressure.
These devices need to be powered from electric energy source.
Some features of wall incoming valves
Wall the valve have certain features:
- possible power – 72 meters cubic in hour;
- integration of the filter of deep cleaning;
- installation has certain difficulties (opening in wall, etc.).
It is necessary to do justice, the valve of wall execution can provide the best air circulation indoors, than window. Besides it has raised heat and noise isolation and does not pass humid air in the room.
Air from the street, getting to pipe of ventkanal, it is cleaned from impurity and pollution, via the labyrinth channel, undergoes additional cleaning and accepts stable speed. Then the cleaned mass of air regulated by special valve with hand or automatic control comes to premises.
But these ventilation devices have also some shortcomings:
- it is necessary to clean filters regularly;
- the system can be chilled at achievement of certain negative temperatures;
- cost is rather high;
- installation demands additional expenses.
Important! This installation can be mounted in rooms with the low level of ceiling. / It significantly increases range of application of the incoming valve of wall installation.
Features of the window incoming ventilation valve
Window devices, thanks to simpler design and mounting mode have gained mass popularity.
It is possible to refer to distinctive features of window plenum ventilation:
- simple device;
- air is purified and arrives round the clock;
- performance of one valve up to 7 m3/hour.
The window valve of the plenum ventilation is the slot-hole device equipped with special valves for regulation.
Mounting of these valves is possible not only in plastic windows, and in any window designs, just plastic windows are most widespread. The device has to be placed in upper part of window system.
- necessary conditions for normal operation of the window incoming valve:
- there has to be additional exhaust ventilation. Unlike wall systems, there are no aspiration ducts here;
- the maximum street temperature is +5 degrees;
- hermetic door to the room or the main room not to allow mixing of other air streams from entrance for the purpose of maintaining efficiency of the incoming window valve.
To air all room, air has to move freely between all rooms. For this purpose it is necessary either to open doors, or to create slot between door cloth and floor.
Responses of the people who have installed this device in the windows demonstrate that the valve is inclined to freezing. But, often, the reason of it, misplacement and adjustment of the device is. There are separate recommendations of experts which should be used during strengthening of frost, for example, to stick the valve or its part with adhesive tape.
The models of valves equipped with automatic equipment have additional functionality:
- the hygrometer, carries out adjustment of air flow on humidity;
- adjustment on humidity;
- adjustment on pressure.
From shortcomings it is possible to note:
- the additional extract is necessary;
- flow capacity not high;
- there are no preliminary filters;
- the valve freezes at low temperatures.
All models of the incoming ventfiltr which are available in the market have the general scheme of work. These devices cope with the task in the conditions of providing with fresh air household, inhabited and other types of rooms.
