Hello Laura,

I have looked at your project, and see that you have connected the air flow
rate (in kg/hr) from the heat pump directly to the building. The air change
input to the building zones must be in (kg/hr air from heat pump)/(kg air
in zone), so that the unit is 1/h. Put an equation between the heat pump
and the building to do this. Although I have not tried to do these changes
to your project, I think that this must be the error.

Kind regards,
Knut Erik

Hello,my name is Laura. I have a problem with my thesis.I don't understand
because I get strange results in my simulation.The internal temperature in
building must be 24-26°C, but I get 8-10°C with heat pump. Why? Where is
the error? I send you my file, please help me.
Thank you in advance.
