Abstract: An air conditioning system has a fan configured for generating an airflow in a predetermined direction. The system includes a heat exchanger assembly configured for being crossed by the airflow for exchanging heat in a controlled manner. An air outlet is located downstream of the heat exchanger assembly and configured for delivering the airflow. The heat exchanger assembly includes an evaporator having a back surface or side facing towards the air outlet and configured for being crossed by the cooled airflow. The system also includes a droplet separator located downstream of and in proximity to the back surface or side. The droplet separator is configured for deviating droplets of water vapor condensed on the back surface or side, so as to prevent the down flow of the droplets of water vapor towards the air outlet.
