Marine Chiller
Marine chille is generally the air after centralized treatment and then distributed to the cabins, such air-conditioning device is called centralized air-conditioning unit, only some special cabins (cabin control room) only a single dedicated air conditioner. Ventilator from the fresh air suction port and the return air suction port respectively into the fresh air (outside air) and the return air, the two mixed by the air regulator processing, and then by the main duct, branch ducts sent to the cabin of the air distribution for people, the cabin in the excess air through the lower part of the door of the grille or leave a gap into the corridor.
Overview
Unit time infiltration into the cabin and cause changes in the room temperature of the heat is called the cabin of the sensible heat load, which mainly includes:
1. Infiltration of heat: summer heat transfer through the ship's envelope accounted for about 26% -31% of the sensible heat load of the cabin.
2. Solar radiation heat: about 25%-27% of the infiltration through the external windows.
3. Human body heat: average per person about 210kJ / h, human body heat accounted for about 16% -18%.
4. Heat dissipation by lighting and other electrical equipment: about 4%-5%.
5. Heat dissipated by food, combustion or other processes
