Compressor Performance

In order to study the working features of automotive air conditioning scroll compressor, this paper uses mathematical model of working process to analyze it. After studying working process, a equation of suction volume is given. The thermodynamic model of compression chamber and back pressure chamber includes mass conservation and energy conservation. Based on Hydromechanics, leakage models of radial leakage and tangential leakage are discussed. The model lays a foundation of automotive air conditioning scroll compressor performance simulation.

The Mathematical Model

The physical and mathematical model of parallel flow automotive air condition condenser was built based on the analysis of its structure and operating characteristics; then the mathematical model was verified and optimized through finite element analysis and running experiments. The VB programming system was used to do Solidworks pro-development and condenser parameterization design module was built. Finally a condenser design and study platform facing to the heat transfer performance and structure with infinite element simulation and numerical simulation was realized.

Automotive Air Conditioning System

A steady-state mathematical model of a small-capacity Automotive Air Conditioning System (AACS) working with the refrigerants R134a (1,1,1,2-tetrafluoroethane) and R1234yf (2,3,3,3-tetrafluoropropene) is developed. The model considers the major components of the system, namely, the swash plate compressor with fixed stroke, thermostatic expansion valve (TXV) and the compact heat exchangers (flat-tube, louvered-fin evaporator and condenser). In order to verify the mathematical model, an experimental facility has been developed for testing the AACS and experiments are conducted with R134a. The experimental results are also validated with published data. The effects of various operating conditions, namely, the condensing air temperature, condensing air velocity and the compressor speed, on the performance of the AACS are predicted for both R134a and R1234yf. The results of the simulations with R134a and R1234yf are compared with the experimental results obtained with R134a. The results show good agreement with the experimental results, with most of them showing less than 10–15% of variations from the experiment results. The uncertainty analysis is performed and showed that the most of validations follow below 10% difference.
