ÂHi JimThanks for the reply.The Pool Heating System maximum water flow rate, i have played with this, the higher the flow rate the lower is the indoor pool water temperature. It just does not make sense to me. The pool water temperature is at the highest when the pool heating max water flow rate is 0.Peak evaporation rate- where do i adjust that in E+ . I thought that all these options should have been within the indoor pool object.Schedule for diversity of the evaporation ( active vs inactive periods). isn't that the same as the pool people occupancy schedule. Also the pool cover i think should adjust the evaporation, However i am not using pool covers in this project.Dehumidification- I want to get the pool simulation to provide a reasonable result first before starting to look at dehumidificationSame with the basement construction, I want to keep the details as simple as possible until i get it wright. This project will have ended up having 3 different swimming pools. I just want to get one swimming pool to work first before I make the project more complicated. The E+ manual suggest to swimming pools are only linked to floor surface only (the depth is adjusted in the indoor pool object).I have looked at the example (5zone swimming )provided several time and I can't notice anywhere where they adjust the evaporation rate. the vertex linked to the pool surface does not look wright. This is making me questioning the indoor swimming pool object.Do you know if anybody else have modeled swimming pool project or aquatic facilities with different pools and it worked.I hope that you can help me.RegardsJonathanÂOn Monday, 9 November 2015, 11:19, "Jim Dirkes jim@xxxxxxxxxxxxxxxxxxxxxxxxxxx [EnergyPlus_Support]" <EnergyPlus_Support@xxxxxxxxxxxxxxx> wrote:
ÂJonathan,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.
- 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 andÂ
- 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).
- 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.On Sun, Nov 8, 2015 at 6:18 AM, jduverge1979@xxxxxxxxxxxx [EnergyPlus_Support] <EnergyPlus_Support@xxxxxxxxxxxxxxx> wrote:ÂCan 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 helpRegardsJonathan--James V Dirkes II, PE, BEMP, LEED AP
