The invention discloses an air pressure balance device and a refrigerating device, and relates to the technical field of refrigerating. The air pressure balance device and the refrigerating device are invented for solving the problems that in the prior art, due to air pressure balancing, internal frosting of the refrigerating device is caused, and energy consumption rises; the air pressure balance device comprises a communication pipe for communicating the interior with the exterior of a storage chamber and a thin film pipe arranged in the communication pipe; the end, close to the exterior of the storage chamber, of the thin film pipe is in an opened state and is in sealed connection with the periphery of the inner wall of the communication pipe; at least one part of inner wall of the thin film pipe is in an attached state under the natural state; when the air pressure of the interior of the storage chamber and the air pressure of the exterior of the storage chamber are the same, the thin film pipe can stop circulation of the inside air flow and the outside air flow of the storage chamber; when the air pressure of the exterior of the storage chamber is larger than that of the interior of the storage chamber, and the difference of the air pressure of the interior and the air pressure of the exterior reaches the preset value, gas of the exterior of the storage chamber can open the attached-state inner wall of the thin film pipe and enters the storage chamber; and the air pressure balance device is used for adjusting of the air pressure of the interior and the air pressure of the exterior of the refrigerating device.
