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 trnsys-users-requ est@cae.wisc.edu To 27.08.2008 19:37 trnsys-users@cae.wisc.edu cc Please respond to Subject trnsys-users@cae.

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.
