摘要：
This paper experimentally investigates the thermal hydraulic characteristics for three types of fluid on plate heat exchanger surfaces. The three types of fluid are R245fa, glycol and water. The characteristics of heat transfer coefficient Nu and friction factor f are given. The concept of pump power is provided to overall evaluate the enhanced heat transfer. The dimensionless correlation equations of Nu and f factors are provided using multiple regression method. The mean absolute errors for the Nu and f factor are 9.7 and 6.8% in the whole test range.
