Method and apparatus for cooling and dehumidifying air

Abstract

The invention relates to a method for conditioning air by means of a ventilation system, in which in order to set a specified target air state characterized by air humidity and air temperature, air having an initial air state is cooled and optionally dehumidified with the aid of an air cooler ( 10 ), by a coolant supply apparatus assigned to the air cooler ( 10 ) for a coolant supplied to the air cooler ( 10 ) regulating both a coolant mass flux and a coolant inlet temperature in accordance with the initial air state and the specified target air state. Moreover, the invention relates to an apparatus for air conditioning is provided.
