How do marine air conditioners work?

Marine air conditioners operate by using a refrigeration cycle to cool the air inside a vessel. They typically consist of a compressor, evaporator, condenser, and expansion valve. The system circulates refrigerant, which absorbs heat from the cabin air in the evaporator and releases it outside via the condenser. This process not only lowers the temperature but also helps dehumidify the air, ensuring a comfortable environment on board.
