I am conducting an exergoeconomic analysis of HVAC system energy consumption in a classroom, considering three parametric cases: air conditioning only, air conditioning with mechanical ventilation, and air conditioning with a membrane heat exchanger. I am struggling to determine the specific processes I should follow and employ for my research. Should I perform the analysis using software or manual calculations? This study is an extension of a previous study conducted by my senior, and he has provided me with the electricity consumption data for the three cases. Could you please provide some guidance?
