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.
