Experimental study of heat transfer during the boiling of refrigerants on an intensified surface

Ways of improving the evaporator of refrigerators include the use of intensified heat transfer surfaces. Methods for increasing the heat transfer coefficient in boiling were investigated using refrigerants R113, R141b, and R123a. Boiling was conducted on a smooth surface and on a surface with artificial vaporization centres. Heat transfer was higher on the surface with artificial centres. Intensification of heat transfer was not very great.
