[Equest-users] Outdoor swimming pool and heater

Rehana,

 

Estimating the energy consumption of a pool heater can be very tricky.  The dominant mode of heat loss is generally evaporation.  Some major influences include activity level of people using the pool (splashing/stirring increases evaporation), wind speeds, and the use of a pool cover.  The US DOE has some material on the subject:  http://energy.gov/energysaver/gas-swimming-pool-heaters  There is a table on this page which I have used to back calculate and extrapolate heating requirements for a specific project as a sanity check.  

 

Also, ASHRAE HVAC Applications 2015 addresses pool heat loss starting on page 5.6.  The discussion is helpful and provides sound calculation methods, but they are more easily applied to indoor pools than outdoor pools.

 

That’s all I have at the moment; hopefully you can find some additional resources.  

 

Good luck,

Christian

Rehana,

 

You can model pool heater load on electric meter (see image below) with winter months schedule:

Dear All,

I'm trying to model an outdoor swimming pool located at the roof top of a residential building. Pool heater (45Kw) operates from December to March (4 months). 

I was wondering if anyone could help me how to model this scenario, and where to input these consumption values. 

FYI, this is my first time modeling an outdoor pool and pool heater.

Thank you,

Rehana.
