Abstract: Assembly of parts for mutually joining one or more panels of an air conditioning cabinet, the assembly comprising: a wall and one or more profile parts joined to this wall which extend therefrom, which profile parts are joinable with a cabinet panel in such a way that the wall makes no contact with sides of the panel forming the inner wall of the air conditioning cabinet, wherein the wall and the profile parts are chosen such that a low heat transfer coefficient is providable and such that condensation within and exterior to the cabinet is substantially avoidable.
