Dear Trnsys users, I want to modell a classic heating system with radiators (that use hot water, heated from a central boiler) to heat just one zone of my building.
I’m connecting the type 1231 to the 56 using the heating rate (output of the type 1231) as an input for gains in the type56.I also set a two kind of controls:1) on the inlet watrer temperature to avoid problems of convergence: it must be at least 0.8 °C above the room temperature2) on the boiler and on the pump. This control depend on the outlet pump water flowrateI can't solve this problem: when the simulation runs, it does not seem that the boiler is working. If I plot the boiler fluid energy it's equal to zero, the room temperature to heat with radiators falls down upon zero even though it's possible to see two different temperature of the inlet and outlet water of the boiler.Can you please help me?Please find in attached my project
