Sustainability and energy efficiency are one of the issues that attract attention in the real estate sector, something that has been accentuated by the rise in the price of electricity. Every day more people worry about making their home as green and efficient as possible. The Canadian, or Provençal, well is an air conditioning installation used in bioclimatic architecture projects that allows the use of subsoil energy. This system, considered low-temperature geothermal , hardly involves any energy expenditure, which is why it is considered an ecological, efficient and sustainable technology. How does it work? The system basically consists of taking advantage of the geothermal inertia of the ground to condition the air that we make flow into the house through pipes buried at a certain depth in the ground. That is, it is a kind of heat exchanger. If we take into account that the soil temperature at a depth of between two and five meters is practically constant throughout the year, we can take advantage of this temperature conservation to preheat or precool the air that we want to circulate inside, making it flow through pipes.
Buried in the ground, sucking it in and expelling it through ventilation grilles. In winter , the outside environment is cold and the air circulating through the buried pipe (air-soil heat exchanger) is heated before entering the interior. On the other hand, in summer , the outside air is hot and due to geothermal inertia we can lower the temperature of the natural ventilation before introducing it into the interior space. In summary, the air is the thermal Phone Lead conductor, the ground is the heat accumulator , the Canadian tube is the exchanger and our building is the beneficiary of temperate natural ventilation. In addition, these systems can also be connected to the artificial air conditioning system in order to heat the air they use, reducing the thermal jump and, consequently, energy expenditure. This factor is of vital importance in the most extreme climates, where bioclimatic ventilation is not sufficient to overcome the thermal loads of the building, both in summer and winter. In summer it is a perfect substitute for artificial systems and in winter it can work as a complement that helps improve the energy efficiency of conventional systems.
In frozen climates it allows these facilities to be kept defrosted naturally. However, there is a negative point in the efficiency of Canadian wells, which is their application in high altitude tropical areas (where the days are hot and the nights are cold). The origin of Canadian wells, or Provençal wells, as we know them today, originally comes from stone channels buried in the side of a hill. Evidently, these channels had much lower performance than current systems. Advantages of Canadian wells It allows users to achieve thermal comfort inside buildings. Reduces the need to use mechanical support equipment. They require very little operating energy. They only need the energy used to operate the extractor, if necessary. Reduces heating and cooling demand. It can be complemented with a double flow mechanical ventilation system with heat recovery. They require minimal maintenance, limited to periodic cleaning of the pipes. Creates a healthy and renewed environment inside the building.
