Sinclair Heat pump systems are highly energy efficient and promote clean heating and cooling for your vessel whether for the waterways or sea-going.
The system will require a seacock, sea water circulation pump and strainer – required specifications and installation information are in the manual – available from the above downloads tab.
Sinclair water-cooled systems have a high EER(Cooling)/COP(Heating) (Coefficient of Performance) 2.67/3.08 saving electrical energy.
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 evaporated 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 ‘s efficiency. This a/c can effectively cool your boat in water temperatures up to 35°C/95°F and heat in water temperatures as low as 4.44°C/40°F.
