Air recirculation system for stationary store rooms and for cargo spaces of refrigeration ships with high-bay racks

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).
