Abstract

Ships around the world are operated at all weather conditions.
Therefore HVAC (Heating Ventilating and Air Conditioning) systems for ships are
very significant and these systems have to work in limit conditions of outer
climate temperature and moisture. To this end, ship heat load should be known.
Therefore necessary heat load is calculated for various air conditions and ship
speeds. In this paper, the ship’s characteristics having the HVAC system are
studied. Moisture, velocity and energy equations are derived. Firstly Simulink
model is created for one location by Matlab Simulink. For the entire ship’s
HVAC system simulation, heat transfer of the locations with each other and
outer climate are also considered. Desirable temperature and moisture
conditions for locations are derived by adding a PID controller to the model.
