Abstract
An ozone converter includes an outer housing having an inlet and an outlet, a first channel disposed between the inlet and the outlet, and a bypass channel disposed between the inlet and the outlet and separated from first channel. The converter also includes a core disposed within the first channel and a bypass control mechanism that includes one more blocking elements that causes inlet air to pass through the first channel or the bypass channel based on an altitude of the ozone converter. The control mechanism includes a piston that moves between at least a first position and a second position and a bellows that controls a flow a pressurized air to the piston.
Claims17
An ozone converter comprising:
- an outer housing having an inlet and an outlet;
- a first channel disposed between the inlet and the outlet;
- a bypass channel disposed between the inlet and the outlet and separated from first channel;
- a core disposed within the first channel that converts ozone into oxygen as air passes through it;
- and
- a bypass control mechanism that includes one more blocking elements that causes inlet air to pass through the first channel or the bypass channel based on an altitude of the ozone converter, the control mechanism including:
- a piston that moves between at least a first position and a second position;
- and
- a bellows that controls a flow a pressurized air to the piston.
A system comprising:
- one or more air parameter adjusting devices that change one or both of the temperature and pressure of the input air to produce conditioned air;
- and
- an ozone converter in fluid communication with the one or more air parameter adjusting devices, the converter including:
- an outer housing having an inlet and an outlet;
- a first channel disposed between the inlet and the outlet;
- a bypass channel disposed between the inlet and the outlet and separated from first channel;
- a core disposed within the first channel that converts ozone into oxygen as air passes through it;
- and
- a bypass control mechanism that includes one more blocking elements that causes inlet air to pass through the first channel or the bypass channel based on an altitude of the ozone converter, the control mechanism including:
- a piston that moves between at least a first position and a second position;
- and
- a bellows that controls a flow a pressurized air to the piston.
