Análise de eficiência e impactos ao meio ambiente dos fluidos R600a (Isobutano), R134a (Tetrafluoretano), R290 (Propano) e R22 (Clorodifluorometano). 2024. 47 f.

Therefore, sudden variations in the applicability conditions of air conditioning and refrigeration of environments, equipment and other practical situations can be noted. The applications are so varied, so the most efficient refrigeration solutions become varied, therefore increasing the refrigeration efficiency of the systems and minimizing the possible risks of malfunction and dangers to the health of the individual and the community. The present work aims to compare characteristics between two refrigerant fluids and their applicability, observing the preservation of the environment, refrigeration potential, application risks to be minimized or avoided, ultimately obtaining a discussion that will lead to the conclusion about which fluid to use in the system of refrigeration for a given practical situation, making use of analytical analyzes and simulations through the CoolPack software of fluid performance in certain parameters.Attribution 3.0 Brazilhttp://creativecommons.org/licenses/by/3.0/br/Fluidos refrigerantesComparação de fluidosAplicações de fluidos refrigerantesbachelorThesis
