The present invention discloses a high-altitude balloon with a phase change regulating airbag, including a main airbag; a load basket for equipping mission equipment and loads; a phase change regulating airbag for directly or indirectly regulating the differential pressure of the high-altitude balloon to keep the differential pressure within a safe range when the balloon changes altitude; a phase change work gas for filling the phase change regulating airbag; a phase change equipment for regulating the volume of the phase change work gas in the phase change regulating airbag The phase change apparatus includes a liquefaction/condensation device; a gasification/sublimation device; a storage tank for storing liquid/solid phase work gases; phase change electronics and accessories; and a control system. The present invention not only provides a redundant way to adjust the height directly by phase change, but also creates favorable differential pressure conditions for the operation of the complex gas pump. More importantly, the whole process of performing height change control always ensures that the differential pressure of the sphere is in a safe range and achieves optimal coordination of height control and differential pressure control.
