The cold is not over yet this winter in the northern hemisphere, marked by climate change. However, it seems that at least something is cooling, and in some places they even began to light up. fireplaces and heaters. But precisely because climate change has hit us hard, it is inevitable to think about how we could heat the premises by reducing energy consumption. fossil fuel. And for that, a rather interesting alternative is canadian wellwhich is based on the use geothermal energyinside the earth.
Also known as provencal wellit is a mechanism that serves both for heating and for cooling houses with minimum contribution of external energy. And it’s easy to do Heat exchange between the air in the houses and the underground, which has a more or less constant temperature throughout the year.
Thus, it is possible to have heating and air conditioning with the same installation and with minimal contribution to global warming. In fact, it is so advantageous in this respect that World Meteorological Organization He chose it to acclimatize his rooms.
This is how a Canadian well works
Speaking of underground temperatures, it’s very hot. inside the earth. However, the Canadian well is not that deep. Basically, the pipes in which heat exchange takes place arrive at approximately from 2 to 5 meters, depending on the temperature you want to reach. At this depth, the temperature fluctuates between 18-24 degrees, so it is ideal for year-round living.
Now we must remember that heat is always lost, cold cannot be transported. Therefore, in winterwhen the air inside the houses is colder, it is passed through pipes, so that the underground air gives off heat.
While in summer, the air inside houses is much hotter. For this reason, it gives off heat inside underground pipes, so that when it circulates indoors again, it comes in much hotter.
It should be noted that if the installation was originally intended to heat houses in the winter, it is called a Canadian well. If, on the other hand, the original idea is to cool them in the summer, it will be a Provençal well. But since then the same setting is used for bothBoth concepts are interchangeable.
Not all floors are the same
The Canadian well will work optimally in soil with good thermal conductivity. This also contributes pipe materials. However, if the earth is not good, there is little sense from them.
For this reason, before making installations, it is necessary to carry out a survey of the ground. It is known that the worst drivers rocky, sandy or dry soilstherefore, in such cases, it may be necessary to look for another option.
What are the components of a Canadian well?
Without a doubt, the main components of the Canadian well are pipelines through which air passes. However, there are other important details for its operation.
For a start there should be air intake point, which captures air from outside the earth. It must be at a suitable height so as not to trap polluted air, and in addition, it must have a grating to prevent the entry of insects and other small animals that may nest or clog air ducts.
They are also used filters to purify the air for recirculation. And, of course, heat exchangerswhich are responsible for transferring heat from outside air to underground or vice versa, as needed.
Without a doubt, this is a type of heating that would be very useful in these rare winters that await us. And, of course, a way to cope with the suffocating summer heat without resorting to those fossil fuels that, little by little, will suffocate us more and more every day.
