[TRNSYS-users] type 927 outlet source temperature

[Emre Arpaci]

hello trnsys users
I m heating a greenhouse with water source heat pump as you see in the
figure.
I m using a lake as the heat source ( open loop system)
my heat pump values are there

Rated heating capacity : 58120 kj/hr
rated heating power : 15120     kj/hr
inlet source flowrate : 1700 kg/hr
inlet load flowrate : 2600 kg/hr

and my lake montly temperatures
january : 4 santigrad degree
february :5
march : 6 ...etc.

so my question is that my heat pump output source temperature and the inlet
source temperature are same,   is this normal ?

I thınk the output source temperature should be less than inlet source
temperature( 4 degrees and changing montly ). because the source energy is
absorbed in heating mode.

thanks
