Indoor unit for an air conditioning system

摘要

This invention relates to an indoor unit for an air conditioning system. The indoor unit is characterised in that a louver (10) is turnable in two opposite directions from a closing position at which the louver substantially closes an outlet port(1). The louver has a curved cross section with a concave surface (10a) and an opposite convex surface (10b). Further, control means (27) is provided ,and the control means controls the movement of the louver so that the concave surface is directed substantially upwards when the conditioned air is to be discharged forwards, and so that the concave surface is directed substantially backwards when the conditioned air is to be discharged downwards. <IMAGE> <IMAGE> <IMAGE> <IMAGE>
