Abstract

The air conditioning system of a riverine patrol and supply type ship constructed by Cotecmar is constituted by a cold water circulation circuit through which centrifugal pump supplies 21 fan coils, by means of which the parameters of human comfort are guaranteed. In this article, the Power Diagnosis of the system is presented with the aim of establishing the possible opportunities for saving on the ships, calculating the losses in the system and determining the equation and the equivalent curve with which the “pump-system” set’s point of operation was found. The result of the diagnosis shows that most of the losses that take place are due to pipes, accessories and fan coils, reason why a group of measures oriented towards the reduction of power consumption are proposed and that are reflected in a better operation and in the advantage taken of the resources with which one counts upon.
