In some countries they are applying new building systems aimed at reducing energy consumption and respecting the environment.
It involves passing ante, s entering the house, renovated part of fresh air through pipes buried in the soil to a depth of about 1 to 2 meters. In winter, the ground at this depth, is hotter than the outside temperature: cold air is preheated during its passage through the pipes. With this system, the air sucked into the system vetilación not taken directly from outside (through the window vents), thereby resulting in savings of heating. In summer, conversely, the ground is colder than the external temperature: in that case the relative freshness of the soil is used to temper the air entering the housing. Geothermal energy is a well-known ancient system in the past
Energy, environment, low power and comfort
The renewal of fresh air necessary for the safety of buildings and our own health is a major source of heat loss in our hogares.Una Once the house is well insulated thermally insulating even, it is estimated that losses from ventilation a 20 to 30% .The introduction of cold air through a simple flow ventilation systems even if used in periods of a few seconds, leads to energy losses that our current and future homes can no longer afford, on especially if we are to achieve low power consumption habitat and preserve as much as possible the potential energy needs. Therefore, the ventilation double recovery system energy flow is one of the reference systems for a house under consumption if the air captured by the ventilation system is preheated by the heat of the earth, bringing the system ventilation is optimized for minimal energy expenditure.0 1 2 3 4 5 6 7 8
