Hi all,
I modeling solar collector system with storage tank used in pre-heating the air (with heat exchanger water-air).
As a storage tank I'm using Type 60c and do the standard connections between circ.pump, controller.... the solar collector I connect with the heat exchanger (inside the tank). I insert another circulating pump connecting it to the flow and temperature at Inlet 1 of the tank and Then the flow and temperature of Outlet 1(Type 60C) I connect to the source inlet of the heat-exchanger (Type 5 or Type 650...) on the other load side are defined the necessary parameters for air.....
But in the simulation the outlet temperature 1 from the storage tank and the source outlet temp. from the heat exchanger are the same i.e. like there is no heat exchange (also the same happens if I connect with the aux.heater Type 6 there is also no temp.increase).
What am I doing wrong should I change the storage tank or...?
