RE: [EnergyPlus_Support] Re: Swimming Pool HVAC





Thanks to all who have made suggestions!  I am well along with planning, but still have some issues to work out.  The biggest issue that remains unresolved is how to model the specialty HVAC unit for the pool which uses recovered condenser energy for both reheat and pool water heating.

For the thermal simulation of the actual swiming pool, I use an EMS code with the equation (1) of the ASHRAE Handbook HVAC Application 2007 chapter 4

Another aspect is that with a tank object you can garantie the integration of the energy neaded to heat the water an account for water loss, that would corresponde to a certan water consumption. That latent loss into the zone would have to be introduced into the zone with another object.
