<p>A method for operating a liquid-to-air heat exchanger device comprises: determining a dew point temperature of ambient air; determining whether the dew point temperature is higher than a temperature of the liquid, and as long as this is the case operating the heat exchanger device in a pulsed operation mode according to: allowing the liquid to flow through a first heat exchanger stage during a predetermined period of time; preventing that the liquid flows through the first heat exchanger stage, monitoring the temperature of the air at the exit of the first heat exchanger stage, said temperature indicating a first increase, remaining awhile constant and then showing a second increase; detecting the second increase and terminating the preventing that liquid flows through the first heat exchanger stage once the second increase was detected.</p> |
