Processing of gases flowing into and out of an enclosed space

Claim 1

A METHOD OF VENTILATING A REGION COMPRISING AN ENCLOSED SPACE BY TRANSFERRING GAS FROM SAID REGION TO A SECOND REGION OF A DIFFERENT MOISTURE CONTENT WHILE CONTROLLING THE TRANSFER OF MOISTURE BETWEEN THE TWO REGIONS WHICH COMPRISES IN COMBINATION: (A) FLOWING GAS CYLICALLY INTO SAID SPACE THROUGH A FIRST MOISTURE TRANSFER ZONE WHICH ZONE PROVIDES A PASSGAE BETWEEN SAID REGIONS AND IN CHARACTERIZED BY THE ABILITY TO REMOVE A SUBSTANTIAL PORTIN OF THE MOISTURE CONTENT IN THE GAS PASSING THROUGH IT PER CYCLE, (B) SIMULTANEOUSLY FLOWING GAS CYCLICALLY OUTSIDE OF SAID SPACE THROUGH A SECOND MOISTURE TRANSFER ZONE WHICH ZONE PROVIDES A PASSAGE BETWEEN SAID REGIONS AND WHICH ZONE IS CHARACTERIZED BY THE ABILITY TO REMOVE A SUBSTANTIAL PORTION OF THE MOISTURE CONTAINED IN THE GAS PASSING THROUGH IT PER CYCLE, (C) SIMULTANEOUSLY INTRODUCING A SECOND STREAM OF RELATIVELY DRY GAS AS COMPARED TO THE GAS IN SAID ENCLOSED SPACE INTO SAID ENCLOSED SPACE, (D) CYLINDRICAL ALTERNATING THE DIRECTION OF FLOW OF GAS THROUGH SAID FIRST AND SECOND ZONES, WHEREIN THE FLOW OF GAS THROUGH THE ZONES IS SUCH THAT SUBSTANTIALLY NO BREAKTHROUGH OF THE MOISTURE WITHIN SAID ZONES OCCURS AND WHEREIN FLOW THROUGH A ZONE INTO ONE OF SAID REGIONS IS ACCOMPANIED BY FLOW OUT OF THE SAME REGION THROUGH THE OTHER ZONE.

Claim 2

A METHOD OF VENTILATING A REGION COMPRISING AN ENCLOSED SPACE BY TRANSFERRING GAS FROM SAID REGION TO A SECOND REGION OF A DIFFERENT MOISTURE CONTENT WHILE CONTROLLING THE TRANSFER OF MOISTURE BETWEEN THE TWO REGIONS WHICH COMPRISES IN COMBINATION: (A) FLOWING GAS CYLICALLY INTO SAID SPACE THROUGH A FIRST MOISTURE TRANSFER ZONE WHICH ZONE PROVIDES A PASSGAE BETWEEN SAID REGIONS AND IN CHARACTERIZED BY THE ABILITY TO REMOVE A SUBSTANTIAL PORTIN OF THE MOISTURE CONTENT IN THE GAS PASSING THROUGH IT PER CYCLE, (B) SIMULTANEOUSLY FLOWING GAS CYCLICALLY OUTSIDE OF SAID SPACE THROUGH A SECOND MOISTURE TRANSFER ZONE WHICH ZONE PROVIDES A PASSAGE BETWEEN SAID REGIONS AND WHICH ZONE IS CHARACTERIZED BY THE ABILITY TO REMOVE A SUBSTANTIAL PORTION OF THE MOISTURE CONTAINED IN THE GAS PASSING THROUGH IT PER CYCLE, (C) SIMULTANEOUSLY INTRODUCING A SECOND STREAM OF RELATIVELY DRY GAS AS COMPARED TO THE GAS IN SAID ENCLOSED SPACE INTO SAID ENCLOSED SPACE, (D) CYLINDRICAL ALTERNATING THE DIRECTION OF FLOW OF GAS THROUGH SAID FIRST AND SECOND ZONES, WHEREIN THE FLOW OF GAS THROUGH THE ZONES IS SUCH THAT SUBSTANTIALLY NO BREAKTHROUGH OF THE MOISTURE WITHIN SAID ZONES OCCURS AND WHEREIN FLOW THROUGH A ZONE INTO ONE OF SAID REGIONS IS ACCOMPANIED BY FLOW OUT OF THE SAME REGION THROUGH THE OTHER ZONE.
