PCT No. PCT/SE80/00026 Sec. 371 Date Sep. 30, 1980 Sec. 102(e) Date Sep. 30, 1980 PCT Filed Jan. 30, 1980 PCT Pub. No. WO80/01605 PCT Pub. Date Aug. 7, 1980.An apparatus for achieving a draught-free environment within a defined zone of a larger room a heating ceiling is used. The heating ceiling is in form of a frame (2) having exchangeable foil sheets (4) intended to reflect heat from heat dissipating bodies, if any, within the zone. The heating ceiling has a heat loop (6) to produce additional heat complementary to the heat reflected by the foil sheets from the bodies so that a constant temperature is kept within the air volume of the zone. For control of the additional heat there is a sensor arranged in a chimney-like opening (9). The sensor is connected to a control circuit (7). With the heating ceiling there is obtained a wall-less and thereby an accessible zone having a well defined environment and mainly a constant temperature. Examples of applications for the heating ceiling are rearing animals, treating burns, and other activities where maintenance of draught-free environment and of constant temperature is important. |
