Title in Portuguese
Análise da eficiência energética e da viabilidade dos ciclos de absorção na frigorificação de cargas
Keywords in Portuguese
eficiência energética
Abstract in Portuguese
Este trabalho aborda a problemática do transporte de carga frigorificada, sob a ótica da eficiência energética da unidade frigorífica. São propostas alternativas para conservação de alimentos, independentemente do frio. Embora incapazes de substituir totalmente o frio, podem ser uma alternativa em vários casos. É analisada a tecnologia de frigorificação atualmente empregada, enfocando custos do sistema, eficiência energética e efeitos da atual tecnologia sobre o meio ambiente. É desenvolvido o projeto preliminar de uma unidade de refrigeração por absorção, que é analisado comparativamente com as unidades por compressão a vapor. Este estudo mostra que o sistema de refrigeração por absorção pode ser viável em muitas aplicações onde não se dispõe de energia térmica ou mecânica.

Analysis of energy efficiency and viability of the absorption refrigeration cycle load

Abstract in English
This study analyses refrigerated freigth transportation, under the scope of refrigeration energy effeciency. There are several alternatives for food conservation, independently of refrigeration. These existing technologies are not capable of completely replacing refrigeration, but they could be utilized in many cases. The refrigeration techonology currently used is analysed, focusing on system costs, energy efficiency and environmental impacts. A preliminary design of an absoption system was done and an analysis was performed comparating it with the compression units. Conclusive analysis of the system will depend of the evaluation of the experimental unit. This study shows that refrigeration by absortion could be viable in various aplications where no electricity or mechanical energy are available.
