The invention belongs to the technical field of low-temperature heat exchange, and particularly relates to a circulating system for a near space environment and an aerostat, and the circulating system comprises an air inlet circulating module, a phase-change heat exchange module, a refrigerating and heating circulating module and a flow control module. The full contact between the phase change working medium and the phase change heat exchange module is realized through the air inlet circulation module. The liquefaction and vaporization process of a phase change working medium is achieved through the phase change heat exchange module, flow distribution of refrigerants in the first heat exchanger and the second heat exchanger is achieved through the flow control module, it is guaranteed that the refrigerants with the large flow flow flow through the first heat exchanger in the refrigeration mode, and it is guaranteed that the refrigerants with the large flow flow flow through the second heat exchanger in the heating mode. Rapid switching between a refrigeration mode and a heating mode is achieved through the working medium circulation module, so that the rapid liquefaction and vaporization process of the phase change working medium is achieved, finally buoyancy and height are regulated and controlled through large-volume change of the phase change working medium, and long-term stable flight of the stratospheric aerostat is achieved.

    本发明属于低温换热技术领域,尤其涉及一种用于临近空间环境的循环系统及浮空器,循环系统包括进气循环模块、相变换热模块、制冷制热循环模块和流量控制模块。本发明通过进气循环模块实现相变工质与相变换热模块的充分接触。通过相变换热模块实现相变工质的液化及汽化过程,通过流量控制模块实现制冷剂在第一换热器及第二换热器内的流量分配,制冷模式下保证较多流量制冷剂流经第一换热器,制热模式下保证较多流量制冷剂流经第二换热器。通过工质循环模块实现制冷模式与制热模式的快速切换,从而实现相变工质的快速液化及汽化过程,最终通过相变工质的大体积变化调控浮力和高度,实现平流层浮空器长期稳定飞行。
