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
