[EnergyPlus_Support] Re: Pools in E+

All right, thanks for that reply. I am going to take a look at this and I'll probably get back to you if something is not clear enough (Sorry about that...)

Thanks for your time James

This sheet includes psychrometric calculations as custom Excel functions.  Frankly, I do not remember all of my assumptions, and would need to review the equations carefully in order to explain better.  (I do not have the time to do so, at this moment, however.  Sorry!)

One was used for the winter months when the pool water is heated.  The other was used for summer months when the pool is not heated.  They are used to provide the "Use Flow Rate Fraction Schedule" for  WaterHeater:Mixed object.
