COMPARAÇÃO DE COMPRESSORES BITZER EM TÚNEL DE CONGELAMENTO

Abstract

The energy efficiency of refrigeration equipment is increasingly important for industries and buildings, due to the magnitude that such equipment represents in the consumption of electricity. In refrigeration systems the best known is the one that operates with steam compression cycle. In this cycle, the compressor is the most complex and most expensive equipment. Thus, special care must be taken, as in addition to problems such as wear and lack of lubricants, it is subject to damage due to the incorrect or faulty operation of all other components. Within the existing compressors, the reciprocating compressor can be commercially considered the workhorse of industrial refrigeration, dominating the capacity range below 300 kW (85 TRs). Thus, this project aims to experimentally analyze the performance of single and double stage refrigeration compressors used in the company's products.
