Design
In order to get the more comfort possible, it is important to design the system in a very precise way. For a correct design it is necessary to consider the UNI EN 1264 norm.
First of all, it is necessary to know the characteristics of the building, especially the exposition respect to the cardinal directions and the insulating grade in order to be able to calculate the heat dispersions. Inside each room the comfortable temperature is usually 20°C with a maximum superficial temperature of 29°C.
Fundamental is the covering chosen for the different rooms: it’s important to know the material and the thickness of the covering. The ceramic tiles offer a minor insulating, while the wooden coverings have a major insulation.
It is preferable to install the manifold in a central position, in order to optimize the distribution of the inflow and return circuits. This distribution can be done in two configurations: “spiral” or “snake”. The first solution is preferable: the heat distribution is more homogeneous, because the return circuit runs in the middle of the inflow circuit. On the contrary, with the “snake” distribution there is a gradual diminution of the superficial temperature, moving from a side of the room to the other. The pitches are the distance between two subsequent pipes. The more utilized are the 15 cm and 10 cm pitches. Sometimes in buildings where there are big glass surfaces it is possible to have different pitches in the same room.
For designing tasks Giacomini’s technicians use a particular software, developed internally and named giacoklima® Tool, that is distributed also to thermo-technicians and designers.
