a blower cover and an air conditioner using such blower . a rollable sheet is locked between two side plates by rollable connectors . a belt plate is secured between the side plates to lock the rollable sheet between the side plates . the belt plate also directs air from the blower . the blower cover can easily be assembled at a work site without welding or expert metal working . the blower cover is used in an air conditioner in which air is forced upwards from the blower and the air is directed into a heat exchange unit by one or more air deflectors . another air deflector directs air coming out of the heat exchanger in an upwardly direction out of the air conditioner and this air deflector also directs any condensate downwards toward a drain system generally located below the heat air conditioner .
