Re: [EnergyPlus_Support] Re: Swimming pool object: unrealistic result- volume of make-up water too big

Hi German

Thanks for the response. You said in your response that you had a realistic result. How did you get the result if there was a mistake with the water input flow rate? Would this mistake apply to all the variables results including heating rate, evaporating rate

So what you saying is that i need to adjust the pool heating max heating flow rate. If so , do i need to adjust all the flow rate connecting to the pool?

I'm pretty sure that I have try various values for the pool heating max heating flow rate in the past. But what i don't understand is why the volume was still too so high. I have performed several water and energy audit on several aquatic centres and the max water  per month that they use which include make-up water is around 4000 kL.

You said that there might be a bug with the indoor pool object, do you mean  that's why my results are unrealistic or do you think that I made some mistakes somewhere.

This is part of a research project at Uni and i need to provide some results in  two weeks. Do you have any suggestion?

Regards

Jonathan

Hello Jonathan, I see that you have used DesignBuilder to develop the model and add the swimming pool afterwards. I have done this before with realistic results, but as you can see in the bug I reported (https://github.com/NREL/EnergyPlus/issues/4805) water flow input was asked in m3/s while it actually was used internally as kg/s. 

It seems to be corrected in v8.4 but there may be still a bug there. It seems that they have not updated Energy+.idd file and still shows m3/s as unit in the IDFEditor. I will report that in Github.

Hope this clue is useful for you...

Cheers,

Germán.
