Abstract

The article is devoted to intensifying the process of heat exchange for the use of surface-active agents (surfactants). For example considered milk cooling, performed in normalized heat exchanger. It is shown that the overall heat transfer coefficient of heat exchange equipment can be improved by adding appropriate concentrations of surfactants to fluids. By adding the optimum concentration (0.05 ... 0.15) masses. %. Cheap nonionic surfactant to the "ice" and water (0.5 ... 0.6) weight. % natural surfactants to milk the overall heat transfer coefficient calculated exchanger increases by 40 %, while its hydraulic resistance is not increased. The paper also counted the economic efficiency of this method of intensification. Energy savings for one heat exchanger for the year is 59161.4 usd.
