Summary

Mini channel tube is the state-of-the-art design for compact and high efficiency heat exchanger. However, their enhancement of heat transfer rate comes with the cost of increased frictional pressure drop. With the introduction of new low GWP alternative refrigerant, the pressure drops of these new working fluids inside mini-channel must be known as a basis for application in engineering design. In this work, the pressure gradient of alternative refrigerant inside channel is investigated at a range of mass flux and heat flux. The data is compared against correlation within literature for the engineering application.
