Brief description, advantages, further prospects for application.
One of the promising directions for improving the efficiency of refrigeration equipment, which is characterized by a high level of energy consumption, is the use of nanofluids as working fluids and coolants. An important stage in the design of refrigeration equipment using nanocold carriers and working fluids based on nanofluids is the technology of their preparation, which ensures the colloidal stability of nanoparticles in a liquid and the availability of reliable information on thermophysical properties.
The objects of study are model liquids, nanocoolants, nanooil, nanocoolants, refrigerant/nanooil solutions. The main goal of the project is to develop a technology for preparing technically important nanofluids with increased colloidal stability, obtaining comprehensive information about the parameters of phase transitions and caloric properties of technically important nanofluids in order to create a new generation of technological media to improve the efficiency of refrigeration equipment.
Research methods: experimental study of the effect of nanoparticles and surfactants on the colloidal stability of nanofluids, experimental computational study of phase transition parameters and caloric properties of nanofluids promising for use in refrigeration equipment.
The project included an experimental study of the colloidal stability of nanofluids created using various technologies, and a comprehensive theoretical and experimental study of the parameters of phase transitions and caloric properties of these nanofluids. Procedures for creating nanofluids that can be used as coolants and working fluids in refrigeration equipment have been developed.
