| titleOfInvention |
Energy efficient, inexpensive extraction of oxygen from ambient air for portable and home use |
| abstract |
Apparatus and method for separating oxygen directly from air, operating at substantially atmospheric pressure and recuperating energy used for cooling incoming air. An ambient air input leads from the atmosphere to a vessel for confining gases. A cryocooler has a cooled surface in the vessel for directly condensing oxygen from the air at substantially atmospheric pressure. The cryocooler cools the cold surface to a temperature greater than the boiling point temperature of nitrogen and not greater than the boiling point temperature of oxygen for condensing oxygen. A liquid/gas separator separates the liquid oxygen from residual gases which both flow out through separate outputs. Air is propelled through the system at substantially atmospheric pressure by an air impeller. A heat exchanger recovers cooling energy and dehumidifies incoming air by transferring heat from the incoming air to outgoing gases. |
