Hello, 2 heat exchanger of same size put in parallel and in series which are better technically as well as commercially. Please guide as i simulated both cases, series connection showing more heat duty compared to parallel.

If you used the same design in both, it should be obvious to you that the series operation is more effective without any calculations.

Q=U*A*LMTD. The exchangers in series have higher fluid velocity which increases the heat transfer coefficient. Calculate the LMTD and the U for the exchangers in both cases and compare. Also notice the pressure drop for the exchangers in the two cases.
