Abstract (en)

[origin: WO2013030080A2] The invention relates to a method for operating a liquid-to-air heat exchanging device, in which heat is exchanged between the liquid and the air at least in a first passive heat exchanging stage (2), comprising the following steps: determining the dew point temperature of the ambient air, determining if the dew point temperature of the ambient air is higher than the temperature of the liquid, and if this is the case, operating the heat exchanging device in an operating mode described as pulse operation according to the following steps: allowing the liquid to flow through the first heat exchanging stage (2) during a predetermined time period, preventing the liquid from flowing through the first stage, and measuring and monitoring the temperature of the air after the air has exited the first heat exchanging stage (2), wherein the temperature of the air measured after the air has exited the first heat exchanging stage (2) indicates a first temperature rise, then remains at an approximately constant level for a certain time, and then indicates a second temperature rise, detecting the second temperature rise, and ending the prevention of the liquid from flowing through the first heat exchanging stage (2) after the second temperature rise has been detected, and repeating said steps until the dew point temperature of the air is higher than the temperature of the liquid.
