Prefabricated ventilating panel including heat transfer means

A prefabricated ventilated panel for supplying temperature-modified air to an enclosure, comprising

• a. a vertical core member (1) formed of heat-insulating material;
• b. a vertical planar outer facing member (2) formed of heat conducting material, said facing member being connected in parallel spaced relation with said core member;
• c. means defining at least one generally vertical passage (4) between said facing and core members;
• d. means defining an air inlet opening (5) for supplying ambient air to the lower end of said vertical passage;
• e. means (7) defining a generally horizontal passage which communicates at one end with the upper end of said vertical passage, said horizontal passage means extending rearwardly completely through said core member and terminating in an air discharge opening, whereby air introduced in said vertical passage via said inlet opening flows successively upwardly through said vertical passage in heat transfer relation with said outer facing panel and through said horizontal passage means for discharge into the enclosure;
• f. means defining a by-pass opening (10) in said outer facing member adjacent the upper end of said vertical passage for introducing ambient air directly into said one end of said horizontal passage means;
• and
• g. damper means (9) movably connected with said panel for displacement between first and second positions in which said horizontal passage means is alternately in communication solely with said vertical passage and with said by-pass opening, respectively.
