[0035] The working principle of the combined cold storage door that can prevent the cold storage door from freezing provided by the utility model is as follows:

[0036] Step 1: When it is necessary to open the cold storage door to enter the cold storage, start the second motor 19, the second motor 19 drives the bidirectional threaded rod 18 to rotate, the bidirectional threaded rod 18 drives the four internal threaded sliders 20 and the two door panels 15 to move away from each other, open the external cold storage door, then after the personnel or the transport vehicle enters between the internal cold storage door and the external cold storage door, close the external cold storage door, start the first motor 7, the first motor 7 drives the reel 6 to rotate, the reel 6 reels the door curtain 9, open the internal cold storage door, and now the personnel or vehicles can enter the cold storage. This door opening method can effectively avoid direct exchange of air inside and outside the cold storage;

[0037] The second step: to prevent the edge of the door curtain 9 and the first guide rail 4 from freezing, which would prevent the door curtain 9 from opening normally, start the hot air blower 12. After the hot air blower 12 heats the air, it flows into the two U-shaped tubes 10 through the air supply pipe 13 and the connecting pipe 11 to heat the first guide rail 4. Then the air flows back to the hot air blower 12 through the return pipe 14 to form a circulation, thereby effectively preventing the edge of the door curtain 9 and the first guide rail 4 from freezing.
