Re: [EnergyPlus_Support] Re: the condenser fan energy for air-cooled chiller





Francesco,
If you're considering the condenser fan power, it certainly should vary with cooling load. You should consider posting that as a bug.

It seems that the fan power is not modulated. I mean, I looking the output data and even if the provided cooling is 1/3 (for example) of the nominal value the fan power is the nominal value. I have to model a chiller that can modulate the fan power. Therefore I'm writing 0 as "condenser fan power ratio" and then I'm modifying the COP in order to take into account the fan power. Then I should check if the curves take into account both the compressor and the fan, but I don't have enough information for that. Any comment, please?

Coffee conversation: People are often unreasonable, irrational, and self-centered. Forgive them anyway. If you are kind, people may accuse you of selfish, ulterior motives. Be kind anyway. If you are successful, you will win some unfaithful friends and some genuine enemies. Succeed anyway. If you are honest and sincere, people may deceive you. Be honest and sincere anyway. What you spend years creating, others could destroy overnight.. Create anyway. If you find serenity and happiness, some may be jealous. Be happy anyway. The good you do today will often be forgotten. Do good anyway.. Give the best you have, and it will never be enough. Give your best anyway.

In the final analysis, it is between you and God. It was never between you and them anyway.
