Internal, or liquid-suction, heat exchangers are used with the primary goal of ensuring the entry of refrigerant in the liquid phase to the expansion device. The greatest COP gain is primarily determined by the thermodynamic parameters linked to the relative increase in refrigerating effect. Large latent heat of vaporization refrigerants often does not gain as much from condenser subcooling in support of a cooling system. Computational fluid dynamics (CFD) is used to study the effects of the turbulence model, which requires the solution of two transport equations. A technique was developed to study the thermal effect on the heat exchange process between two fluids. To observe the temperature effect on 17 tubes, the diameter was altered twice, first to 6 mm and then to 4 mm. The flow procedure happened in one direction, and the tube that contains the tubes had a diameter of 50 mm. The best-case scenario is the case where the pipe diameter is 4 mm and the heat exchanger are 300 mm in length. Through the results, the enthalpy was improved in the simulated cases to 423.2 h [KJ/M]. The length of the heat exchanger greatly affects the values of the exit temperatures and the temperature difference. For a length of 225 mm, the temperature reached 15.73 °C, and for 300 mm, it reached 13.847 °C. The significant reduction in temperatures helps increase the coefficient in the refrigeration cycle. A high coefficient of cooling in the heat exchanger appears when the length is 300 mm compared to other lengths.

When a vehicle takes a turn at a high rate of speed, it is frequently rendered unstable, and the vehicle may lose touch with the way if the cornering is paired with a bump in the pavement. This can be especially dangerous if the vehicle is traveling in the opposite direction of the bump. The strategy asks for the design and manufacture of a suspension system and wheel assembly that are robust enough to withstand high speed cornering while also being able to ride comfortably over bumps of varied degrees of severity, Another crucial element of vehicle design is material choice since it allows us to lighten the vehicle while still maintaining the safety of the planned components, improving performance, We used the data and dimensions of the Honda Accord 2012, available in its own company, in our theoretical calculations to obtain the forces Depending on braking and bending conditions required to be applied to the components of the double wishbone suspension system which is made by solidworks2022 Where we selected the wishbone system's fundamental dimensions. Then, in order to determine the optimal materials for the Honda accord2012 double wishbone suspension system, a structural study is carried out with the aid of the ANSYS2021R2 program by modelling the loads exerted on just this suspension system individually using the wheel, wishbones, and knuckle. The suspension system's parts were then placed through some kind of series of quality control tests to make sure that only the best materials were utilized in their fabrication This is due to the fact that it is one of the most crucial sections of the vehicle. The results of this study were then used to refine the suspension system's design and select the best metals for it, by taking into account, among other things, the material's strength, cost of manufacture, weight, and availability. The purpose of the document, among other things, is to: A-Research all chassis parameters. B-Analyze a double wishbone suspension system parameter and try to optimize it. c) A study of the performance-influencing factors for the current suspension systems, d-To get the highest performance as well as material for a double wishbone suspension system, reduce or control the extent to which these aspects have an impact during the design phase.
