Some other things to consider for modeling pools.
Public pools are often drained and refilled as frequently as every month. This is a huge energy and water consumption factor, often larger than the day-to-day use of heating and dehumidification.
ASHRAE Applications has a pretty good section on Nataoriums to help with load calculations.
Also, getting loads from RETScreen can work. TRNSYS has a pool component you can purchase from Transsolar.
There are DX heat recovery AHU's that can save a significant amount of energy, Dectron and Seresco are two common manufacturers. The savings from the heat recovery can be modeled(approximated) in eQUEST, but I haven't tried other tools.
Hope that helps.
In case the question pertains to "how to calculate latent loads and equipment sizing" -- here is one page of resources that will help you determine the model inputs in generating the latent load.

There are a lot of variables though pertaining to how active the pool occupants will be throughout the day, temperature of the pool, whether there is a cover, etc.

Please add more details about the specifics of your project, what you are trying to achieve (is the fact that it's a swimming pool relevant to your question or are you just asking how to model a HPWH?), and what you have tried so far.
