Abstract
"APERFEIçOAMENTO EM SISTEMA DE REFRIGERAçãO". Especialmente de um sistema aperfeiçoado de refrigeração, o qual utiliza conceitos baseados na variação da velocidade do refrigerante no interior do sistema, a começar pelo aumento da velocidade na saída do condensador (1) através de um tubo (2) de 'Venturi' que faz com que haja um aumento de vazão e conseqüente queda de pressão e temperatura, que acarretará na eliminação do estado líquido do refrigerante, após o condensador (1), permitindo abolir o sistema de evaporação (tubo capilar ou válvula de expansão) de modo que o refrigerante já expandido é levado por um tubo de maior diâmetro em que a diferença de diâmetros provoca nova expansão, fazendo baixar mais ainda a temperatura do refrigerante no agora expansor (3) (substituto do evaporador). O tempo de permanência do refrigerante a baixa temperatura no expansor (3) é aumentado pela redução da seção do diâmetro do tubo (6) de retorno para o compressor (7), que por sua vez aspirará um refrigerante mais frio e de baixa pressão poupando o compressor (7) que poderá ser de menor potência."REFRIGERATION SYSTEM IMPROVEMENT". Especially for an improved refrigeration system which uses concepts based on varying the refrigerant velocity within the system, starting with increasing the velocity at the condenser outlet (1) through a venturi tube (2) that makes flow rate and consequent drop in pressure and temperature, which will result in the elimination of the refrigerant liquid state after the condenser (1), allowing the evaporation system (capillary tube or expansion valve) to be abolished so that the already expanded refrigerant is carried by a larger diameter pipe where the difference in diameter causes further expansion, further lowering the refrigerant temperature in the now expander (3) (evaporator replacement). The low-temperature refrigerant residence time in the expander (3) is increased by reducing the diameter section of the return pipe (6) to the compressor (7), which in turn will suck in a cooler, low-pressure refrigerant while saving the compressor (7) which may be of less power.
