Ventilação variável como estratégia para redução do consumo energético em túneis de congelamento

Abstract

This work of course conclusion discerns demonstrate through case study the possibility of reduction of electric energy in freezing tunnels, using variable ventilation. The research developed in this study is the experimental type, where it was carried out the record of data before and after the implementation of the system, was analyzed and correlated the data. From the analysis of the information it was observed that with the actions of the variable ventilation system was possible to obtain reduction in energy demand of the tunnel, which represented an annual gain of up to R$ 45.0000, with a cost benefit ratio of 0.13 in the deployment of this system. The results also appears improvement in the performance of the tunnel, decreasing the time of freezing of the products while keeping as a reference to the maximum temperature required for surveillance of - 18ºC.
