[Equest-users] dry inlet delta T

[Verena Kindl]

Hi all,

i modeled a dry cooler and i saw i have to input the dry delta T temperature. The help states " The value is the difference between the entering fluid temperature and the entering air temperature ". My fluid has a temperature 37°C entering and 26°C leaving the dry cooler but I do not know the entering air temperature I mean that depends on the weather. Or does it mean that is the difference temperature the cooling tower is working without any fluids used? I tried several values and only 50 F is working but I do not know why.

Thanks.
