Air conditioning for comfort
The heating, ventilation and air-conditioning system on a cargo ship is usually a simple direct expansion ducted system. It must also be able to provide heating during cold weather. Usually steam coils are provide for heating, and injected steam for control of humidity.
As in refrigeration system, the air-conditioning system uses seawater for cooling. A shell and tube type of heat exchanger is installed for that purpose. It has its own cooling seawater pump.
The air-conditioning system sometimes trips when the cooling system flow is reduced or the sea temperature is high.
The heavily polluted river waters in some ports can sometimes cause the cooling water strainers to choke up with plastic bags as often as every 4 hours.
A ship traveling through the Red Sea, can experience air-conditioning system tripping at the engine room control room because the sea temperature is high, and the heating load is high.
