Abstract

The evaporators 4 and associated drain troughs 12 of an air treatment unit utilizing two heat pumps are defrosted by warm exhaust air conveyed along the underside of each drain trough 12 via a single damper 13 to one or both of the evaporators 4, the evaporators 4 being substantially horizontally situated over the drain troughs 12 at a distance therefrom. <IMAGE>
