Hi everyone,
i want to ask one question
1- i prepared new window type (using Window software) and import it into TRNSYS. I want to see changing behavior the overall heat transfer coefficient (U-value) of the new glazing material added
by changing inside and outside temp difference like delta T = 10, 20, 30 ,40,and 50). i am using this equation to calculate U = Q / A( T) where t is difference of inside temperature and ambient
temp. i am using type 56 for the simple building structure. my results are very small change in u-value. and simulation results doesn't satisfied the experimental results.
2- i am using type 2 energy demand for heating and cooling am i taking wrong Q for the calculation. can i calculate u value by using TRNSYS i am not sure in TRNSYS ist calculate U and then Q or calculate Q by some other method????
3- (N-TYPE 50) in output can i get mathematical reference of this output NTYPE to make sure how this type calculate u-value of glazing and frame.
Thanks for your time .
