Dimensioning of a hybrid system boiler - solar collector of evacuated tubes, for the defrosting of fish

Abstract

The fishing sector, better known as the fishing industry, is part of the primary sector, which is why it is an important economic activity in the world, as it is part of the human diet and industrial processes. The processing of fish in industries requires defrosting, this is achieved by superheated steam produced in a boiler which uses fuel oil as primary energy, this increases production costs. This work aims to design a hybrid defrost system that is efficient, reduces costs and takes advantage of solar energy for water preheating. The purpose of the system is to reduce fuel oil consumption by taking advantage of solar thermal energy through evacuated tubes, for which the system is analyzed using the first law of thermodynamics. From the reduction of fuel oil consumption, the amount of CO2 emitted into the environment will decrease, as well as production costs.
