ABSTRACT:
High-pressure air from the air supply is admitted into the heater system through a pressure regulator. Fuel, such as propane, enters the system from a fuel canister. The air and fuel of controlled volumes mix and flow together into a catalytic combustion chamber where combustion is initiated by a spark generator. The heat of combustion is caused to pass through the walls of the combustion chamber, then through thermoelectric modules, converting part of the heat to electricity. The remaining and larger part of the heat passes to a heat exchanger on the opposite side of the thermoelectric module. Circulating water passes through the heat-exchanging chamber, absorbs the heat produced by the combustion reaction and is further pumped to the diver's suit. The electricity generated by the thermoelectric modules is used to power an electric motor driving a circulating pump.
