Abstract (en)
It is provided a system for cleaning a blower (11) and an air inlet filter (16) of an air condition unit (3) using condensed water. The system includes a reservoir (1) for condensed water, a first sub-system for facilitating flowing pressurized liquid in a duct (4) having spraying outlets (6), and a second sub-system for removal of sprayed liquid out of the air condition unit. The cleaning liquid includes condensed water and a cleaning additive. The air inlet filter may rotate on a pair of pulleys (17a,17b), and the filter is exposed to the sprayed liquid by rotating a pulley while spraying. The system includes barriers (8) disposable in a separating position between the cleaned parts and other objects. The system also includes a manipulating handle (45) or an electric motor (7), for placing the barrier. Electrical circuitry (47) may automatically initiate cleaning the parts on turning-of the air condition unit. The system include a chamber (10) for a cleaning additive and a mixing mechanism for mixing the cleaning additive with the condensed water. The sub-system for removal of sprayed liquid out of the air condition unit includes a drain tray (12), a used water chamber (2) and a drain pipe (48).
