Re: [EnergyPlus_Support] Swimming pool water temperature not reaching desired temperature





Jonathan,
Did you notice that your pool surface name is invalid?  It must the the name of the floor surface for the pool area (per the I/O Reference)

Jonathan,
I have not reviewed your IDF in detail, but here are some ideas:
  • I'm guessing that because you've set the Pool Heating System Maximum Water Flow Rate = 0, that no pool heating occurs.
  • Inline image 2
  • I have not used the (relatively) new indoor Pool object in E+, but E+ needs to know at least a couple of things in order to calculate pool heating energy
    • a peak evaporation rate and 
    • a schedule for diversity of the evaporation (e.g., active vs. inactive periods in the pool)
  • Since evaporation represents a heat loss equivalent to ~950 BTU/hr, the load on the pool heater is the product of the peak rate and the diversity fraction.
  • If you have a dehumidification system, the evaporation is also a latent load for your dehumidification system.  This can be represented with an OtherEquipment object, as shown below (but may be included in some fashion by the Indoor Pool object).
  • Inline image 1
  • If you want to get more detailed, and assuming the pool is built into the ground, you might also consider defining the pool as a "basement" zone with walls of the same material as the pool sub-surface walls and a heating system which maintains that zone at the pool's water temperature
I hope this helps.

Can anybody have a lot at what I'm doing wrong.

I am simulating an indoor swimming pool. I manage to get the project to simulate. However i cannot get the pool water temperature to 29 degree. And also there is no pool water heating rate. I thought maybe i have not properly identify the swimming pool (vertex). I compared mine to the swimming pool example provide 5Zoneswimming pool. In the example , the vertex use to reflect the surface of the swimming pool does not seems right as well.


I have attached the result spreadsheet and the idf file.

Can somebody please help


Regards

Jonathan
