    • The invention relates to a refrigeration system for the cooling of goods in a closable and refrigerable space (1) inside a building, said space featuring a conveyor (5) for carrying and concurrently refrigerating goods (7) to be refrigerated, refrigeration means (2) for cooling said space to a temperature of -5°C..-40°C, and possible means for the transfer of air within the space, the space having its walls provided with at least one goods opening (3) extending to the exterior of the space for carrying goods into and/or out of the space through said goods opening/goods openings by means of the conveyor (5). The space (1) has its walls provided with at least one air intake (4) for supplying the space with make-up air (It) and the air discharging from the space (1) by way of the goods openings (3) is replaced essentially in its entirety with fresh make-up air (It) supplied by way of the air intake/air intakes (4), the make-up air having a water content of about 3,0 - 0,01 g/m 3 of make-up air, the amount of water being preferably less than 1 g/m 3 of make-up air. The make-up air (It) is produced by an air transfer unit (10), which is located outside the space and which features a dryer device (150) containing a moisture absorbing material and enabling its moisture absorbing material to be regenerated, as well as an air supply duct (170) which enables passing the make-up air (It) from the building, from outside the space, or from outdoor air through the moisture absorbing material of the air dryer device (150) and further into the space by way of the air intake/air intakes (4) opening into the same, and said air supply duct being also provided with means (110) for carrying and possibly pressurizing the make-up air in the air duct, as well as with possible means (120) for the cooling of air in the air supply duct (170) and for relieving the air of condensation water produced in the cooling of air.
