Abstract
PCT No. PCT/FR87/00504 Sec. 371 Date Oct. 6, 1988 Sec. 102(e) Date Oct. 6, 1988 PCT Filed Dec. 16, 1987 PCT Pub. No. WO88/04757 PCT Pub. Date Jun. 30, 1988.The independent unit for heat exchange particularly for the ventilation of a room or premises is configured like a box (12) wherein are formed two passages (40 and 42) having an undulated shape and wherein circulate in counter-current air drawn in the room and rejected to the outside and outer air introduced into the room. The invention applies particularly to the ventilation and air conditioning of the premises or rooms of a building.
