Resumo

A method for experimental data adjustment consisting of correction equations for the performance parameters of the cycle, like, compressor work or refrigerant effect, when operation conditons departed from those established in testing standards, is here presented. Correction equations are proposed for evaporator capacity and compression power consumption, for situations when condensing pressure has not followed standards conditions or has not been controlled during experiments. The method was tested against experimental data where it was possible to control the variation of the measured variables. Good agreement was obtained.
