1. Apparatus for controlling the temperature of an air space surrounding one or more air separation canisters, said apparatus comprising: a. one or more air separation canisters; andb. a thermal conditioning unit including: i. a hot air inlet;ii. a cool air inlet;iii. a first outlet air line connected to said one or more air separation canisters, said thermal conditioning unit operable to deliver conditioned air to be separated through said first outlet air line to said one or more air separation canisters;iv. a second outlet air line leading to the area in which said one or more air separation canisters are located, said thermal conditioning unit operable to deliver heated waste air through said second outlet air line to said area; andv. a first branch line connected to and between said cool air inlet and said second outlet air line leading to said area;vi. a first valve in said first branch line, said first valve operable to control the amount of cooling air delivered through said first branch line to said second air outlet line and thereby optimize the temperature of the heated waste air delivered through said second outlet air line to said area. 2. The apparatus of claim 1, and further comprising a housing surrounding said one or more canisters, said housing defining said area to which said heated waste air is delivered. 3. The apparatus of claim 2 wherein said housing is thermally insulated. 4. The apparatus of claim 3, wherein said second outlet air line includes a second branch line vented to ambient. 5. The apparatus of claim 4 wherein a second valve is located in said second branch line. 6. The apparatus of claim 5 wherein said second valve is located in said second outlet air line between said second branch line and said housing. 7. The apparatus of claim 5 wherein said second valve is located at the juncture of said second outlet air line and said second branch line. 8. The apparatus of claim 1 and further comprising a temperature sensor and controller operable to control said first valve in response to the temperature sensed in said housing. 9. The apparatus of claim 5 and further comprising a temperature sensor and controller operable to control said second valve in response to the temperature sensed in said first outlet air line.
