[TRNSYS-users] Storage tank type 4

[David BRADLEY via TRNSYS-users]

Over the course of the year usually the energy balance works out fairly 
well. However, if there is a difference in the amount of energy stored 
in the tank at the beginning of the simulation and at the end of the 
simulation, you have to account for that in your energy balance. Type4 
has an output for this value. Also, it may be that you are adding 
auxiliary energy to the tank. Type4 has a number of modes in which it 
can automatically keep itself at a set point temperatures.

kind regards,

  David
