The Design Of A Refrigeration System Using The Nozzle Technology And Performance Analysis Study

Currently, most of the refrigeration system uses a vapor compression refrigeration cycle, the refrigeration system using power-driven, multi-energy but also cause environmental pollution. Energy conservation is never-ending, improve the efficiency of the cooling system, it can save more energy, help reduce environmental pollution and promote sustainable development of economy and society. In recent years, research on application of ejector refrigeration systems, more and more traditional applications ejector refrigeration cycle system performance has improved.This article is consideration of the above background, we constructed using nozzle technology, the new compression/ejection refrigeration system, and the method of calculation of its research program. First, the new refrigeration system was introduced, it how to improve the system performance are described focusing on the principle, and an important component of the injector system for a simple introduction. After the new refrigeration system, thermodynamic model, based on the refrigeration system is analyzed two aspects:on the one hand to keep the injector configuration parameters unchanged, in order to change the evaporation temperature, condensation temperature, the working fluid pressure and lead body jet pressure to obtain different working parameters, refrigeration system capacity, coefficient of variation of COP and the jet, while the conventional vapor compression refrigeration system were analyzed; on the other hand to keep the system working parameters unchanged sequentially change the nozzle outlet diameter, primary throat, length and angle of the diffusion chamber mixing chamber, obtained under different structural parameters ejector refrigeration system cooling capacity, COP and jet variation coefficient, also with conventional vapor compression refrigeration system were analyzed. By studying these two aspects, get new refrigeration system and the traditional distinction between a vapor compression refrigeration system and the best operating conditions to obtain the optimum injection parameters and structure parameters of the new cooling system, so that the performance of the refrigeration system to achieve the most Excellent. On the analysis of the working condition of system parameters and structural parameters of injector on the refrigeration system, the influence of main components of the new cooling system has carried on the design and calculation, and the corresponding selection, to the actual engineering application has a certain theoretical guiding significance.
