RESUMO:

The increasing energy demand has been a subject constantly discussed. The increase in energy production capacity and the implementation of new energy sources try to get around this problem. However, these measures alone will not be enough to support the growing demand. Increasing the energy efficiency of mechanisms and processes presents itself as an ally of fundamental importance for the continuity of global energy supply and development of society. The compressors are equipment that have wide applicability both in the industrial sector and at home and are responsible for high energy consumption. This work aims to study an alternative valveless compressor, object of a patent of invention, which is presented as an alternative to improve the energy efficiency of conventional reciprocals. Its unique mechanism is responsible for opening and closing the valve system with a focus on reducing load losses during the suction and discharge phases. In order to evaluate the improvement caused by this mechanism, it was mathematically simulated a one-dimensional model in the non-valved compressor's MATLAB software and the numerical results obtained were compared as the mathematical model of an automatic compressor with automatic valves described in Volf's (2017) master's work. The comparative analysis showed an increase in the isentropic efficiency of approximately 12.4% and an increase in the volumetric efficiency of approximately 3.3%. A parametric analysis made it possible to identify the area of the suction and discharge window section, equal to 6.00 cm², as the optimized value to obtain the highest isentropic and volumetric efficiency values when compared to the initially proposed model.
