The experiment on the fluid flow characteristics of R134a in an evaporator with horizontal microtube was performed. In this study, the air volume flow rate and the ambient temperature has changed from 19 to 47.5 l/s and 26 to 32 0C, respectively. Besides, a comparison between the micro evaporator and the macro evaporator (FNA) was also conducted. The pressure drop of the macro evaporator is lower than that obtained from the micro evaporator....
