COOLING > COOL DURING SUMMER
Radiant floors cooling system is not based on the convective criteria, but rather on irradiation. A non-conditioned environment is, during summer, very humid and its temperature can be above 30°C; for this reason, the human body, not being in comfortable conditions, is obliged to disperse most of the heat only through evaporation. Sweating is increased as well as the heart beat and breathing, and therefore the people are quite uncomfortable in such an environment.
On the contrary, if the floor is cooled at a temperature of about 18-21°C, the heat is absorbed, and the temperature of the entire environment is lowered. With a lower environmental temperature, the human body – which is in optimal conditions at 36,5°C – disperse heat by means of irradiation to the surrounding environment, in particular to the floor, which is cooler.
This comfort is determined by the law by which the irradiation rate grows exponentially at the increasing of the temperature difference between bodies. For this reason, by lowering the temperature of the surfaces, there is a thermal exchange, which leads to a comfortable feeling.
The floor cooling system alone, however, doesn’t get rid of the relative humidity in the air: in order to avoid dew on the floor, it is necessary to install an electronic unit with anti-condensation probes and a mixing valve to continually monitor the temperature of the water.
Furthermore, dehumidifying the environments it is possible to achieve the optimal comfort for the well being of the people.
