Exemple de système de réchauffement de l'eau de mer utilisable dans les dispositifs aquacoles

This paper deals with the possibility of heating cold seawater entering a seaside aquacultural nursery during winter. The proposed model contains a ‘warm’ water source and two heat exchangers in series (heating and pre-heating). The model evolves for the system a set of values for various pairs of exchanger surface areas. The values of the working temperature are calculated for different flowrate ratios and for several surface areas given a set value of 15°C for the ‘warm’ water source. The paper further develops the optimising of the ratio S₂/S₁ for minimum capital investment and takes the further step of investigating the possibility of failure to achieve a set T_i for a specific pair of heat exchangers during the cold season at a specific seawater site.
