Compare operation of different working fluid of HPHX, in air conditioning system for energy saving

Heat pipe heat exchangers (HPHXs) are playing a considerable role in different fields including air conditioning systems. We applied such an air conditioning system for treating hot and humid air withthe use of HPHXs in series which were charged with methanol and ethanol as working fluids. In this research, experiments were carried out for 2, 3, 4 and 5 rows and two defined conditions of inlet air. energy saving values for both working fluids were calculatedand compared in order to obtain the optimum number of heat pipe rows and best working fluid. Results showed that in both defined conditions, 3-row HPHX had the best performance, and methanol has better operation than ethanol
