Abstract:
Due to the growing environmental concerns of CFCs, today the use of green refrigerants such as CO2 in air conditioning systems is of great concern. Of course, the use of carbon dioxide refrigerants, despite all the benefits, is also facing challenges. One of the main challenges in using this refrigerant is the high pressure in the high pressure refrigeration cycle (from compressor output to expansion valve inlet) due to the critical nature of the thermodynamic cycle of refrigeration by this refrigerant. In this thesis, with the purpose of investigating the use of CO2 refrigerant in the first condenser product based on the National Vehicle Platform (NP01), an experiment is first carried out to evaluate the thermo-fluid behavior of the refrigerant while passing through the condenser. The experimental data obtained in the previous section will be verified. Finally, the model will be used to optimize the first condenser product based on the national automobile platform, with the aim of improving the use of CO2-based fluid. With the experiments, the designed condenser showed a high degree of rut transfor- mation, and has been able to meet the air conditioning requirements standards for gas in the air-conditioned car system, and we can say that one of the big challenges in this field has been cleared up.
But it is worth noting that there are many challenges in this regard, and one of the challenges is that the condensation build up with the pressure we solved in this study. The high efficiency of this condenser was able to answer all the questions in a special and innovative design; it was able to achieve high returns, both good heat transfer and high resistance to pressure. And these points all made it possible to take some great time to use green refrigerators in automobiles; and to answer a lot of questions in this regard, and it is a great age for the environment, and this research has been a quick and timely step for replacing the refrigerants, since In 2035, all freewheeling bases should be removed.
