Energy characterisation of an aquacultural installation in closed loop

摘要

This examined a methodology for the energy characterization of a closed loop aquacultural plant. A simplified dynamic model representative of the temperature response of the water volume is defined. The input data are the air temperature, the insolation and the injected power. According to experimental readings, the value of parameters results from the minimization of a quadratic error criterion between the model output and the water temperature measurements. The model enables the user to quantifythe losses and to make energy consumption calculations. The studies, carried out on a pilot pond, allowed the testing of the methodology. Coherent results were first obtained for the open pond and then for the pond equipped with transparent thermal protection. Finally, a closed loop designed for the breeding of turbot was studied. From experimental readings, a model was established and validated by following the same procedure.
