Increase the efficiency of refrigerating equipment PP151
The technology of producing nano - oil, nano - coolant and nanotubes and adjusting their properties and characteristics of heat transfer is intended for implementation in order to reduce energy costs for the production of artificial cold. The fundamental difference between the proposed technology and the prototype is the complex consideration of the properties of nanofluids and the characteristics of heat exchange in them. The introduction of the proposed technology will enable to reduce the energy consumption of the installed refrigeration equipment and the material content of the used heat exchangers.
Main features of the development
Reduction of energy consumption for the operation of the refrigeration compressor - 5 - 10% . Increasing the heat transfer coefficient and reducing the material content of heat exchangers (evaporators and condensers) - 5 - 10% . Basic fluids for the preparation of nanofluids - cool agents, compressor oils, coolants and refrigerants. Applied nanoparticles - metals, metal oxides, fullerenes.
The state of readiness of development
Technologies of preparation of nano - oil, nano - coolants and nanotubes are developed. Their thermophysical properties were studied and the influence of nanoparticles on the energy efficiency of the compressor system, on the coefficient of heat transfer at boiling of nano - liquid and forced convection.
Intellectual Property Protection Status
2 patents for utility model were obtained
The developed nano - liquids will be in demand producers of technical liquids and consumers of these liquids in order to increase the competitiveness of manufactured products. For example, refrigeration equipment, cooling systems of transformers, systems of cooling of internal combustion engines, radio electronic devices (including double use).
