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
ns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 con
-
denser 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 lowers its
temperature. The cooled air is blown through the ducting
and out the supply air grille(s). For reverse cycle heating,
the refrigerant ows 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 tempera
-
ture 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. See
