Performance analysis of an air conditioning system using rotary compressor

Abstract

The most air-conditioned vehicle is the automobile including car, busses, trains, trucks, recreational vehicles, air craft and ships. The major contributions to the cooling load in the transport are the heat from solar radiation and the heat from human especially in of public transport. The performance of car air conditioning system is driven by the rotation of RPM engine. The changes of rotation at high and low speed will give significant effect to the system. This project presents mathematical modeling and analysis computer simulation of car air conditioning systems with the four basic components consisting of compressor, condenser, evaporator and expansion valve. This air conditioning system will be using a rotary compressor with five sliding vanes. A computer simulation model has been developed and the effects of system performance are indicated by compressor speed, pressure ratios have been evaluated. The main objective of this work is to identify the performance of car air conditioning system using a rotary compressor. A FORTRAN programming was applied for the system modeling with R134a as the test refrigerant properties. For the validation of the perform a comparison study of this work with the previous experimental data to determine the accuracy of program as well to evaluate of the simulation results. The expectations of this project is to have an agreement between the simulation result and theory and these will be a fundamental to the future research from the aspect of the design compressor and the development of an air condition system.
