Simulation mixing test platform for full-temperature-range large-temperature-difference environment of airport runway

The invention discloses an airport runway full-temperature-range large-temperature-difference environment simulation mixing test platform. The air conditioner comprises a control system, a refrigerating system, a heating device, a circulating air system and a case, the interior of the case is divided into left and right cabins; the left cabin is divided into an upper experiment cabin and a lower equipment cabin, and the experiment cabin is divided into a front cabin and a rear cabin by a permeable plate; parts of components of the circulating air system, the heating device and the refrigerating system are installed in the rear cabin, and other components of the refrigerating system are arranged in the equipment cabin. The front cabin is used for placing a to-be-tested runway material test piece; part of components of the control system are installed in the right cabin, the other components are arranged in the experiment cabin, and the control system is electrically connected with the refrigerating system, the
