hi trnsys users
I have a question about solar fraction I m heating a space with solar assisted heat pump. and I want to calculate solar fraction with trnsys. I m using fan coils to heat up the space. so how can ı calculate solar fraction.If I do that the useful energy gain of collector in montly divided by required heating load in montly.
is it give me the montly solar fraction or am i wrong ? ( I dont have dhw in my system)
regards
