[TRNSYS-users] Type 344 - Outdoor pool

[David Bradley]

Kent,
 It depends a bit on how the pool temperature is controlled. The Type344 
model assumes that the pool is not thermally stratified - so you need to 
put a pretty massive amount of energy in to increase the temperature. If 
you are controlling pool temperature by turning on and off a pump and a 
heater that maintains a supply water temperature, Type6 is a good choice 
because it is designed to modulate its energy input to maintain a flow 
stream at a set temperature. If you are sensing pool temperature and 
turning on and off a heater that always runs at the same capacity, you 
might be better off using the boiler model that is in the TESS HVAC library.
Kind regards,
 David
