Residential building ventilation New York

Zero energy buildings , 16.10.2019г.

             Today, we invite you to consider a topic such as residential buiding ventilation New York.  Inhabitants the USA are increasingly beginning to be interested in the basics of residential building ventilation New York.
             Building ventilation contributes to comfort and air quality, removing contaminants (odors, moisture, combustion products from heaters, germs, etc.).  It also helps to preserve the building, avoiding disturbances due to insufficient ventilation: condensation and mold development.  There are differences between natural or mechanical ventilation, as well as other systems that also allow the air to cool: free cooling, re-radiation in summer.
              Residential building ventilation New York.  Natural ventilation.
              It is provided with two openings, one low, through which there is fresh air, and the other high through which the extinguished air in the room flows.  The fresh air inlet at the bottom can be placed under the heater to prevent cold air.  Everything happens naturally.  The main advantage of using open windows for natural ventilation is that the energy costs are zero, since there are no injectors and extractors.  The disadvantage of natural ventilation is that it is insufficient in itself in many applications.
              Residential building ventilation New York.  Mechanical ventilation.
              Aeration systems with controlled mechanical ventilation fans are used to control the extraction of fresh air.  Single-flow systems allow stale air to be exhausted by a fan located on the roof of a collective duct.  Distribution ducts connect the collective duct to the exhaust openings located indoors and in the kitchen.  In dual flow systems, fresh air enters the room through ducts and a fan.
              Residential building ventilation New York. Free cooling.
              Free cooling directly uses the outside air to ventilate and cool the room.  This allows the room to be cooled without conditioning until the outside temperature is lower than the desired room temperature.  It can replace the heat transfer distributed by the compressors by means of three-way valves when the ambient air temperature permits.  It consumes much less energy than (air-conditioning).
