Re: [TRNSYS-users] cooling tower

[David BRADLEY <d.bradley@tess-inc.com>]

Hatem,

 There is not really an easy way to debug this problem. The cooling tower is unable to solve at a particular point in the simulation. Make sure that you are not trying to use the cooling tower in a cold climate during winter. Freezing water in the cooling tower can cause the model to have a hard time solving (and in any case it can cause real life problems to run cooling towers in cold winter climates). If that is not the case and if you have made sure that your cooling tower parameters are realistic and that the tower is appropriately sized to the load then I would recommend sending your project to your distributor for assistance.

kind regards,

 David

Dear Trnsys users,

I would like to know what does mean this error message. In fact, this error is located in cooling tower component (Type 51).

the utility routine psychrometrics, which calculates the thermodynamic properties of moist air, 

has called with a wet bulb temperature above the maximum wet bulb temperature for the given pressure. 

Please check the routine which calls the psychrometrics routine for possible sources of errors

Thank you,
