<p>In an air conditioning unit (10) comprising a supply air duct (12), an exhaust air duct (26), a heat exchanger (15) for transferring heat between supply air and exhaust air, and a watering device including means (20) for supplying water at the upper end of vertical exhaust air passages of the heat exchanger (16) and means for collecting water draining off from the exhaust air passages, a substantially vertical section (15) of the exhaust air duct (26) is provided immediately adjacent the downstream side of the exhaust air passages, and the water collecting means (21) is also adapted to collect water flowing out of that exhaust air duct section. A secondary heat exchanger may comprise said vertical exhaust air duct section (15) and be arranged in series with the first heat exchanger (16).</p> |
