A UTILIZAÇÃO DE INVERSORES DE FREQUÊNCIA EM COMPRESSORES PARAFUSO: fazendo um comparativo de economia de energia entre compressores parafuso com inversores de frequência e os compressores com velocidade constante

Abstract

Compressors are equipment developed to admit and compress air. inside a reservoir or in direct air compressors to admit, compress and escape air. Over time, new types of compressors have appeared, including the screw compressor that can operate with constant or variable speed. For the compressor to work with variable speed, frequency inverters are used, which make the engine work by varying its speed without losing its torque. Aiming a lot regarding the energy consumption of a machine, in view of this, a comparison of the cost benefit was made between conventional compressors and screw compressors with frequency inverters, savings in certain cases can be noted, reaching up to 38%. when related to energy consumption, reduction in the number of maintenance, in conventional compressors the starts are usually sudden, thus occurring greater wear and tear of parts, whereas in screw compressors with frequency inverter due to the system it has a smooth acceleration and deceleration reducing the mechanical impacts and increasing the life of the parts.
