Saving begins to be programmed from the ground up. Although this is a maxim that at first glance seems exaggerated, the truth is that planning the way in which we want to air-condition our home from the moment it is built will save us from costly and unnecessary renovations. Firstly, energy efficiency begins with insulation: there is no point in heating our home thoroughly if that heat escapes through the window slits or through the walls. Orientation also has an impact on air conditioning: a south-facing facade will be much warmer in winter, but also much more expensive to cool in summer.
Even from the decoration you can take steps towards the ideal temperature of the home: paint the walls light if you live in a warm climate, and dark if you live in a cold area.The most demanded conventional appliance, due to its low cost, is the wall split, which can be placed in a strategic point so that it cools a suitable place in the house and, furthermore, it does not require any building work and can go unnoticed placed in an attic. However, it is a very unsophisticated system, with only one air source, so most of the house is not air-conditioned. Conversely, theduct system covers the entire surface of the home, and its only disadvantage is its installation, which requires major work to distribute the pipes so that they run through all the rooms. Therefore, if we decide before having built the house completely, we only find advantages.
The first and most important one is the saving, because this system allows us to decide which room or zone we are interested in heating or cooling, so we can activate the air only where it is necessary and, by means of the domotics, program it so that no energy is wasted at any time of the day or night. The estimated saving, with an optimal use of the system, can reach 50%, which means a quick amortization of the investment made in the installation, which, if it has been foreseen from the beginning, is not complicated. Once the zones to be air-conditioned have been determined, an optimum temperature is estimated for each site, which is controlled by a central panel. The air is then distributed differently throughout the ductwork by means of a system of motorised grilles and diffusers, pressure relief dampers and local modules.
