Abstract

This article presents a comparative study between the practices recommended by the Society of Naval Architects and Marine Engineers –SNAME– for the design of air conditioning systems on ships and the methodology of thermal charge calculation CLTD/CLF developed by the American Society of Heating, Refrigeration and Air Conditioning Engineers –ASHRAE–. To verify the difference in the results obtained
when applying the proposed considerations and equations of calculus, ship design data of the VI riverine patrol and supply ship built by Cotecmar, it demonstrated that by means of the use of the methodology of the SNAME, over-sized air conditioning systems are obtained. And the global coefficients of heat transference were also evaluated comparing the results tabulated by the SNAME with the values obtained through zone method. Finally, the influence of the calculated thermal charges in the capacity of the equipment of cooling required on the premises of the ship was determined.
