How to choose a ventilation system for the house Bashny.Net

As you know the most important weather in the house. To create and maintain the optimum indoor microclimate will help the ventilation system. Most often natural ventilation is not enough to create a comfortable environment. For this reason, let us consider recuperation exhaust and ventilation system.





Forced flow with application of the suction fanair flow lies at the heart of the ventilation system. To ensure the functioning of the ventilation system will allow air valve, filter, heater, fan and muffler. To the network include air ducts, air intake grille and air distribution devices (grilles, diffusers, anemostate). In the system of ventilation necessary filter that allows you to not only clean the air coming from the streets from debris and dust, but also to maintain a comfortable microclimate. The heater serves for heating the air in the autumn-winter period. It is installed at the customer's request.

If mechanical is not only tributary, but also the exhaust air, it makes sense to install a system of air recuperation in order to save electricity for heating the supply air.

Ventilation system with heat recoverySupply and exhaust ventilation system with heat recovery is very popular. They serve to warm the cold air admitted from the street. When this takes minimal energy. This system allows to save up to 50% due to partial heat supply (cold) air exhaust (warm). Partly because exhaust air heat is not always enough to heat the cold supply air to +20 0C. In extreme cold, incoming air heats up the built-in heat exchanger of the heater.





If the house has air-conditioning system in the summer, incoming air is partially cooled, which will reduce the load on air conditioning system. So, chilled by the air-conditioning system exhaust air passing through the heat exchanger, cools the warmer supply air.

Types of ductsin order to separate supply and exhaust air in the room needed the air ducts.

In a round longitudinal ducts with the smallest resistance to movement of air in a rectangular more. The wiring duct fittings used: elbows, nipples, plugs and others. The ducts from the intake grate to the ventilation unit (or heater when typesetting system) must be insulated to prevent condensation.

General requirements for ventilation systemsExhaust air emitted to the outside above the ridge of the roof. With natural ventilation, all channels are output above the ridge of the roof. If mechanical exhaust ventilation duct in the same output above the ridge of the roof or inside the building or outside.





The fresh air intake in the mechanical system of ventilation is carried out through the intake grilles. It must be placed at least two meters above ground level.

Air movement must be organized in such a way that the air from the premises moved in the direction of areas with the release of hazards (bathroom, bathroom, kitchen).published
