Claim:
Air recirculation system for stationary store rooms and for cargo spaces for refrigeration ships with at least one high-bay rack for stacked or palletized goods, wherein two superimposed air circuits ( 40 , 140 ; 40 ′, 140 ′) are configured in the store room or in the cargo space ( 10 ) of the refrigeration ship ( 20 ) in an area of every rack module ( 30 ; 130 ), whereby at least one rack module, preferably two rack modules ( 30 ; 130 ), are placed in the cargo space and whereby a shaft ( 50 ) for a rack stacker is assigned to each module ( 30 ; 130 ) or a shaft ( 50 ) for the rack stacker is placed between the two rack modules ( 30 ; 130 ) placed the one besides the other, whereby the shaft ( 50 ) serves a common pressure distribution chamber of inlet air for each rack module ( 30 ; 130 ), wherein a junction of the two superimposed air circuits ( 40 , 140 ; 40 ′, 140 ′) ends in front of inlet sides ( 61 , 161 ; 61 ′, 161 ′) of air coolers ( 60 , 160 ; 60 ′, 160 ′) placed above each other, whereby the air circuits run into the inlet sides of air coolers, and wherein each of the air circuits ( 40 , 140 ; 40 ′, 140 ′) passes through an air cooler ( 60 , 160 ; 60 ′, 160 ′) by means of fans ( 62 , 162 ; 62 ′, 162 ′) which are fixed on the opposite side of the shaft ( 50 ) in front of the rack modules ( 30 , 130 ).
