Resumo
Mediante ao desafio da refrigeração e condicionamento de ar para armazenamento de produtos na indústria e controle de qualidade de processos, o presente trabalho visa propor um sistema de refrigeração para atendimento à demanda de um caminhão frigorífico para transporte de carnes. O modelo de referência adotado foi o mesmo proposto pela empresa Thermo King, multinacional responsável pela produção e venda de equipamentos de refrigeração para transporte, a partir da potência mínima de 13.500 BTU/h para a refrigeração do caminhão analisou-se o ciclo de refrigeração com dois pares de refrigerante, amônia/água e R134a/DMF. Para a análise da eficiência energética e eficácia de cada ciclo usou-se o simulador software HYSYS®, através das simulações foram gerados dados para a comparação dos dois pares de refrigerantes utilizados. Em geral, nota-se que a maior eficiência obtida no ciclo foi de 40,8 %.
