ABSTRACT:
TECHNICAL FIELD
The present invention relates to the field of the thermoregulation of a room by means of radiant panels.
BACKGROUND OF THE INVENTION
Generally the conditioning of a room is carried out letting an air current into it with continuity and removing an equal quantity thereof. This is the principle of the conditioning by convection.
However, the comfort of the man in a room derives, at least to a large measure, from the transfer of heat or energy by radiation. The heat transfer by radiation is caused by the giving up of heat of a warm surface to a colder surface. By regulating the transfer of radiant heat and the air temperature by convection, one can achieve an unsurpassable degree of comfort.
Thereby conditioning systems have been developed based on radiation instead of convection. Through radiation one can carry out both the heating and the cooling of a room. The radiation is carried out through radiant panels with electric conductors or pipes for air or water. By “radiant panels” panels are meant in the art that carry out a heat transfer at least for 50% under radiant form.
However the radiant panels presently known are floor or ceiling panels, and the percentage of heat transferred by radiation and not by convection is not high and in any case to operate efficiently they need considerable temperature difference between the panels and the room, which involves energy expenses.
OBJECTS, CHARACTERISTICS AND ADVANTAGES OF THE INVENTION
It is the object of the present invention to provide a system for the thermoregulation of a room with radiant panels operating with a liquid that carries out an energy transfer by radiation to a proportion greater than those available at the present day, and that is energetically more efficient, particularly that can operate with small temperature differences between the thermovector liquid and the room to be thermoregulated, and having a faster response.
To transfer energy in the manner as efficiently as possible, it is provided that in the radiant panels the water or the liquid is in direct contact with an entire radiant surface, or an entire area thereof, of the panels, preventing the convective motions of air from lowering the temperature of the radiant surface itself.
It is, moreover, the object of the present invention to provide such a system, that is particularly advantageous from the point of view of the energy saving.
For feeding the liquid it is particularly provided the use of water of the undersoil. In fact, it turns out to be cool also when the external temperature is high, from a thermic inertia effect of the undersoil itself. In particular one can use a buried water cistern for the supply of water of a habitation, but eventually also a well, or also a purposely realized cistern.
It is an important advantage of the present invention that for its efficiency it can be put in operation with alternative, ecologic energy sources, such as for instance also solar energy, by virtue of the fact that the operating temperature of the panels is much lower than conventional systems.
SUMMARY OF THE INVENTION
Therefore, the subject of this invention is a system for the thermoregulation of a room with radiant panels, comprising a source for feeding thermal exchange or thermovector liquid; radiant panels in which a thermovector liquid passes; means for inletting and means for outputting a thermovector liquid into/from said radiant panels; said radiant panels comprising a rear wall; a front or radiant wall for thermal exchange with a room to be thermoregulated and, between said radiant wall and said rear wall, a gap space in which said thermovector liquid passes in direct contact with the entire radiant wall; said radiant panels comprising means for the mounting thereof onto a wall of said room to be thermoregulated; the improvement wherein in said gap space of said radiant panels baffles are arranged bonded with said radiant and said rear wall by respective edges thereof confining channels which, together with their linear development, sweep all said radiant wall of a radiant panel completely covering the area thereof from behind, for a passage of said thermovector liquid so guided as to uniformly sweep the radiant wall of a radiant panel contacting its area entirely from behind; which channels are vertical channels arranged in parallel, the thermovector liquid being fed thereto from said means for inletting and removed therefrom to said means for outputting by a top and a bottom horizontal manifold in liquid communication with said vertical channels by respective ports; said radiant panels being connected in parallel by putting the top and the bottom manifold of each panel in liquid communication with the top and bottom manifold respectively of another radiant panel or panels;
the sum of the volumes of said ports putting said vertical channels into liquid communication with said top manifold being less than the volume of said top manifold and the sum of the volumes of the ports putting said vertical channels into liquid communication with said bottom manifold being less than the volume of said bottom manifold;
thermal exchange promoting twisted strips being arranged in said vertical channels, and
said radiant panels being built from aluminum box elements.
