Evaporator: Marine Air Conditioning Definition
The cold coil that cabin air passes over. Where the cooling and the dehumidification actually happen.
Evaporator in a Boat Air Conditioning System
Air giving up heat to the evaporator also gives up moisture, which is why a refrigeration system dries a boat and a fan does not. If it ices up, the cause is usually restricted airflow or low charge rather than anything wrong with the coil itself.
Using Evaporator Specifications in Quotes and Manuals
Use this definition to understand a quote, manual or fault report—not as an instruction to modify the boat. Before buying, compare the wording against the current manufacturer documentation. For refrigerant, fixed 240 V wiring or below-waterline work, use the official licensing and standards sources and an appropriately qualified tradesperson.
