Investigation of the optimum number of heat pipe rows in HPHX used for energy saving in an air conditioning system

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 with the use of HPHXs in series which were charged with methanol as working fluid. In this research, experiments were carried out for 2, 3, 4 and 5 rows and two defined conditions of inlet air. Effectiveness and energy saving values were calculated and compared in order to obtain the optimum number of heat pipe rows. Results showed that in both defined conditions, 3-row HPHX had the best performance.
