[TRNSYS-users] type 927

[gabriela vlad]

Dear TRNSYS users,
I'm trying to model a ground source heat pump system used to heat a building.My GSHP consists of: a heat pump (type 927), a vertical U tube ground heat exchanger (type 557), a storage tank with 2 inlets and 2 outlets and no auxiliary heating elements(type 60c) and fan coils(type 928)I noticed greater air temperature in the rooms after connecting the HP with the building ( so the system is working, I have significant heat transfer rates on both sides of the HP and a COP of 2.5) but a have problems with load temperatures of the HP. I don't understand why the load temperature at the inlet/outlet of the HP is about 100oC/105oC. My real GSHP  must provide water with 65 oC (in this case the return water temperature must be 58oC).
Please tell me how I can get this temperature of  65oC. 
Thank you,
Gabriela
