Resumo

This paper discusses the experimental study of the performance of an air conditioning system for the control of their thermodynamic parameters (physical). Such a system is, at its core, composed of a subsystem of vapor compression refrigeration, and a cooling secondary subsystem. In order to evaluate and analyze system behavior with use of variable speed compressor, having as parameter of analysis, coefficient of performance the bench and power consumption required by the same for the use of fixed speed compressor and variable speed. The fixed speed compressor is designed to meet the maximum thermal load of the system, the compressor of variable rotation allows adjustment of the rotation from the fluctuation of the same can work without loss of coefficient of performance with thermal loads relatively low . The advantages and disadvantages of the variation of the increase / decrease in the rotation for the studied system will be presented at the results obtained.
