Results and discussionThe temperature and humidity datum before the air-conditioning of all places in the ship are used asinput for the simulation 15 °C and 29,5 % humidity, respectively. The result graphs of the airconditioningto get the 25 °C temperature and 45 % humidity are shown below.Figure 6. Temperature change in cabin due to timeIt is indicated from the temperature and humidity graphs that the desired reference values arereached rapidly without extra exceeding and steady state error.Figure 7. Humidity change in cabin due to timeChanging the external air temperature effects over the total heat load is observed. At first, anincrease in the external air temperature decreases the total heat load at the heating side, after the specifictemperature increases at the cooling side.19
