The invention relates to a thermal control method for a stratospheric aerostat. The problem that the height and the internal and external pressure difference of the aerostat are changed due to the day and night temperature difference is solved. Comprising a buoyancy ball, a winch, a pull rope, a gravity ball, an auxiliary air bag, an inflation and deflation device, a pressure sensor I, a pressure sensor II and a load cabin, the buoyancy ball is filled with helium, the winch is used for winding and unwinding the rope and adjusting the length of the pull rope so as to adjust the ball falling height, the pull rope is connected with the two balls, the gravity ball is provided with an effective load, and the height needs to be kept unchanged during working. The auxiliary air bag is arranged in the gravity ball, the inflation and deflation of the auxiliary air bag are controlled by controlling the inflation and deflation device, the weight and the internal pressure of the gravity ball are adjusted, the inflation and deflation device is composed of a fan and a valve and is used for inflating and deflating the auxiliary air bag, the pressure sensor I and the pressure sensor II are used for detecting the internal pressure and the external pressure of the gravity ball respectively, and the load cabin is provided with effective loads. Comprising a control device. According to the invention, the height of the aerostat can be kept unchanged and the internal and external pressure difference is constant when the aerostat stays in the air.
