Abstract

The invention provides a low-temperature liquid storage evaporation control system adapted to lunar surface and a control method. The low-temperature liquid storage evaporation control system adaptedto lunar surface comprises a low-temperature liquid storage and heat leakage prevention module, a pump driven spraying and mixing module, a cold energy supply module, and a measurement collection control module, wherein the low-temperature liquid storage and heat leakage prevention module is used for storing low-temperature liquid and reducing heat leakage from the outside world to a low-temperature storage tank; the pump driven spraying and mixing module is used for mixing of low-temperature liquid in the low-temperature storage tank, eliminating thermal stratification, condensing the gas ofa gas pillow and controlling the pressure of the storage tank; the cold energy supply module comprises a low-temperature refrigerating unit, a refrigerating circuit A, a refrigerating circuit B, a pumping heat exchanger and a cooling screen heat exchanger; the low-temperature refrigerating unit is used for generating cold energy and transmitting the cold energy to a cooling screen circuit of the pumping fluid and low-temperature liquid storage and heat leakage prevention module; and the measurement collection control module is used for measurement of various parameters, collection of the sensor data and the control of the system. The low-temperature liquid storage evaporation control system adapted to lunar surface realizes the zero-evaporation storage of the low-temperature liquid on thelunar surface in the low-temperature storage tank by combining the environmental characteristics of the lunar surface and adopting a passive evaporation control and active evaporation control combination method.

Description

technical field [0001] The invention relates to a low-temperature liquid storage and evaporation control system and control method adapted to the surface of the moon. Background technique [0002] Lunar exploration has increasingly become a popular space activity in the world. my country has completed the first two steps of the three steps of lunar exploration, namely orbiting and landing, and then will carry out the third step of the lunar exploration plan and the fourth step of lunar backside exploration. At the same time, my country is actively carrying out demonstrations of unmanned lunar exploration and manned lunar exploration. In short, the moon has become an important destination and transit station in my country's deep space exploration. [0003] Lunar probes successively launched by the United States, Europe, Japan, and India have detected the permanent shadow areas of the lunar poles and south poles. The detection results have confirmed the existence of water ice r...
