Abstract
A gas concentrating system is provided. The system includes, for example, a gas separation system having at least one separation space, at least one sensor connected to the separation space and providing at least one output signal indicative of the progress of gas separation, at least one pump system associated with gas separation system; and a controller. The controller includes, for example, logic reading the sensor output signal and logic controlling at least one parameter of the pump system based on the sensor output signal. The parameter of the pump system can be any parameter affecting the characteristics or operation of the pump system. Examples are disclosed but are not intended to be limiting.
Claims20
A gas concentrating system comprising:
- a gas separation system having at least one separation space;
- at least one sensor connected to the separation space and providing at least one output signal indicative of the progress of gas separation;
- at least one pump system associated with the gas separation system, wherein the pump system comprises a plurality of pumps;
- and
- a controller comprising:
- logic reading the sensor output signal;
- logic controlling at least a first parameter of a first pump of the pump system based on the sensor output signal;
- and
- logic controlling at least a second parameter of a second pump of the pump system based on the sensor output signal.
A gas concentrating system comprising:
- a gas separation means having at least one separation space;
- at least one sensor means connected to the separation space and providing at least one output signal indicative of the progress of gas separation;
- means for providing a positive or negative pressure connected to the gas separation means, wherein the means for providing a positive or negative pressure comprises a plurality of pumping means;
- and
- a means for reading the sensor means output signal and controlling at least a first parameter of a first pumping means and at least a second parameter of a second pumping means based on the sensor means output signal.
A method of concentrating gas comprising:
- sensing the progress of gas separation within a gas separation space and generating at least one output signal;
- reading the output signal;
- controlling at least one pressure based parameter of a first pump assembly based on the progress of the gas separation within the gas separation space;
- and
- controlling at least one pressure based parameter of a second pump assembly based on the progress of the gas separation within the gas separation space.
