When the air-conditioning system works, cold air in the refrigerator is filled into the carriage air cushion 3 through the work of the main pressure pump, and when the pressure in the carriage air cushion 3 reaches a set value, the functions of pressure maintaining and pressure stabilizing are realized through the overflow valve, so that the form of the carriage air cushion 3 is ensured; meanwhile, cold air in the carriage air cushion 3 enters the baffle air cushion 4 through the air pipe 5; when loading, the packing case and/or the packing bag containing the fresh products are placed between the adjacent baffle air cushions 4; the sizes of the packing cases or packing bags of fresh products are different, the magic tape matt surfaces 42 are uncovered, so that the through grooves 41 of the separating air cushion 4 slide along the magic tape matt surfaces 42, the position of the separating air cushion 4 is adjusted, and after the position of the separating air cushion 4 is determined, the magic tape matt surfaces 42 and the magic tape hook surfaces 43 are bonded again to fix the separating air cushion 4, so that the use is convenient; after the fresh products are loaded, the door of the heat preservation carriage 2 is closed, the first inflator pump works, the first inflator pump pumps the gas in the heat preservation gas storage tank 22 into the extrusion air cushion 21, the extrusion air cushion 21 is continuously expanded, and then the extrusion fixation of the spacer air cushions 4 on the two sides is realized, so that the condition that packing boxes or packing bags of the fresh products collide with each other or roll obliquely in the running process of the transport vehicle is avoided, and the transport quality of the fresh products in the transport process is further ensured; when the fresh products in the transport vehicle need to be unloaded, air in the extrusion air cushion 21 is pumped into the heat preservation air storage tank 22 through the first inflator pump, so that the extrusion air cushion 21 is contracted at the top of the heat preservation carriage 2, and the unloading of the fresh products on the transport vehicle is facilitated; when the temperature sensor detects that the temperature in a certain separating air cushion 4 is lower than a set value, firstly, the controller controls the moving part 24 to adjust the position of the corresponding temperature-adjusting air cushion 23 according to the displacement of the separating air cushion 4 fed back by the displacement sensor 25; when the position of the temperature adjusting air cushion 23 is adjusted to be aligned with the partition air cushion 4, the controller controls the second inflator pump to work, the second inflator pump pumps cold air in the carriage air cushion 3 into the temperature adjusting air cushion 23, the adjusting air cushion continuously expands, the second inflator pump stops working until the adjusting air cushion is in contact with the partition air cushion 4, the cold air in the adjusting air cushion is cooled down for air in the partition air cushion 4 in a heat conduction mode, and then the pointed compensation for the position with raised local temperature is realized, so that the stability and uniformity of the temperature in the heat preservation carriage 2 are ensured, and the refrigeration effect of fresh products in the transportation process is further improved.
While the present invention has been described with reference to the embodiments shown in the drawings, the present invention is not limited to the embodiments, which are illustrative and not restrictive, and it will be apparent to those skilled in the art that various changes and modifications can be made therein without departing from the spirit and scope of the invention as defined in the appended claims.
