Specific implementation mode
The utility model is described in further detail below in conjunction with attached drawing：
Referring to Fig. 1, Fig. 2, a kind of freezer air control system for air embodiment of the utility model, including cold, 5, freezer 5 configures
Air compressor 1, heat exchanger and control system.Further include drying machine 2, device for drying and filtering 3, air cleaner 6, the heat exchange
Device includes First Heat Exchanger 4 and the second heat exchanger 7, admission line and the air-filtering with 5 external environment atmosphere of freezer
The input port of device 6 connects, and the delivery outlet of air cleaner 6 is connect by pipeline with the upper inlet of the second heat exchanger 7, and second changes
The upper outlet of hot device 7 is connect by pipeline with the input port of the air compressor 1, and the delivery outlet of air compressor 1 passes through
Pipeline is connect with the input port of the drying machine 2, and the delivery outlet of drying machine 2 is connected by the input port of pipeline and device for drying and filtering 3
It connects, the delivery outlet of device for drying and filtering 3 is connect by pipeline with the import of the inner tube 4.2 of First Heat Exchanger 4, First Heat Exchanger 4
The outlet of inner tube 4.2 be connected to freezer 5；The import of the exterior tube 4.1 of First Heat Exchanger 4 is connected to the cool house internal,
