OVERVIEW
HOW IT WORKS
Your self-contained air conditioner consists of four main components and a refrigerant gas circulating through the
system. The BLOWER draws warm cabin air across the fins on the EVAPORATOR where the heat from the air is
transferred to the refrigerant in the evaporator coil. As the refrigerant evaporates from a liquid into a gas, it absorbs
the heat from the cabin air. The COMPRESSOR then compresses the refrigerant gas and pumps it through the
outer tube in the CONDENSER COIL. The seawater pump circulates cool seawater through the inner tube in the
condenser coil; this cools the refrigerant and condenses it into a liquid. The heat from the refrigerant is exchanged
to the seawater and discharged overboard. The liquid refrigerant is then passed through the EVAPORATOR COIL
and the cycle repeats; removing heat from the cabin air lowering its temperature. The cooled air is blown through
the ducting and out the supply air grille(s). For reverse cycle heating, the refrigerant flows in the opposite direction
through the reversing valve. Heat is transferred from the seawater in the condenser coil to the refrigerant and then
to the air blowing through the evaporator into the cabin. Seawater temperature will directly affect the a/c unit's
efficiency. This a/c unit can effectively cool your boat in water temperatures up to 90°F and heat in water
temperatures as low as 40°F.
