Brief description, positive qualities, further prospects for application:
The aim of the project is to develop the scientific basis for the introduction of environmentally friendly working fluids of a new generation for vapor compression refrigeration machines (refrigerant/nanooil/surfactant/nanoparticles) – nanoridine, which provide a significant increase in the energy efficiency of refrigeration and other heat and power equipment due to the intensification of heat transfer processes during boiling and tribological characteristics
Experimental data on the stability, composition and structure of nanomastils, nanorefrigerants and model nanofluids have been obtained; thermophysical properties of nanomastils, nanocoolants and model nanofluids; internal characteristics of boiling and heat transfer coefficient during the boiling of nanorefrigerants on surfaces with different degrees of wetting. The technology for creating nanofluid working bodies for compression refrigeration machines has been improved and practical recommendations have been developed for the preparation of stable working bodies based on nanofluids.
Experimental information has been obtained on the dependence of the energy efficiency indicators of vapor compression refrigeration machines and the heat transfer coefficient in evaporators on such factors as nanofluid stability, concentration and nature of nanoparticles, and interaction of nanoparticles with a heat-releasing surface.
A thermophysical model has been developed to predict the heat transfer coefficient during the boiling of nanofluids.
