Re: [TRNSYS-users] Type 344 - Outdoor pool



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

Using Type344, I am trying to model a heating system that would maintain a setpoint temperature throughout the year.  What controls would be the best approach?  I have selected Type502 with a Type6 auxiliary heater.  I’ve read the details of Type344 that might suggest a suitable thermostat and heater, and I’m still having trouble.  Anybody out there whom is well-familiar with Type344 and might offer recommendations?
