“…Liu et al [23] conducted measurements of heat transfer and pressure drop of R152a flow condensation in circular and square micro-channels with hydraulic diameters of 1.152 and 0.952 mm. The saturation temperatures were 40 and 50 °C, with mass flux varying from 200 to 800 kg m -2 s -1 and vapor quality from 0.1 to 0.9.…”

A C ritical R eview on C ondensation H eat T ran sfer in M icro ch an n els and M in ic h a n n e lsCondensation in microchannels and minichannels is widely used in small devices such as air-cooled condensers for the air-conditioning and automotive industry, in heat pipes, thermosyphons and other applications for system thermal control. Currently, many research centers all over the world are dealing with the structure and operation of com pact refrigerating devices. This is in line with the trend of 21st century that is moving towards the use of energy-saving and environmentally friendly technical equipment. In the present study, a critical review on condensation heat transfer in microchannels and minichannels is presented. This review include a wide range of different parameters such as the channel diameter (d), the saturation temperature (Ts), the mass flux (G), the vapor quality (x), different working fluids like steam, C02 or R744, FC72, R22, R410A, and R407C, various shapes such as circular and noncircular, different orientations like hori zontal and vertical, and systems consist o f either single or multiple channels. At the end, recommendations for future studies will be given. As a result, this paper cannot only be used as the starting point for the researcher interested in condensation heat transfer in microchannels and minichannels, but it also includes recommendations for future studies on condensation heat transfer in microchannels and minichannels.
