Low-temperature liquid storage evaporation control system and control method adapted to lunar surface

Abstract

The invention provides a low-temperature liquid storage and evaporation control system and control method adapted to the surface of the moon, including: a low-temperature liquid storage and leakage-proof thermal module, used for storage of low-temperature liquid and reducing heat leakage from the outside to the low-temperature storage tank; Drive jet mixing module, used for mixing low-temperature liquid in low-temperature storage tank, eliminating thermal stratification, condensing air pillow gas, and controlling storage tank pressure; cold supply module, including low-temperature refrigeration unit, refrigeration circuit A, refrigeration circuit B, pump Sending heat exchanger and cooling screen heat exchanger, wherein the low-temperature refrigeration unit is used to generate cold energy and transmit it to the cooling screen circuit of the pumped fluid and cryogenic liquid storage and leakage prevention heat module; measurement, acquisition and control module , for the measurement of various parameters, the collection of sensor data and the control of the system. The invention combines the characteristics of the lunar surface environment and adopts the method of combining passive evaporation control and active evaporation control to realize the zero-evaporation storage of the low-temperature liquid on the lunar surface in the low-temperature storage tank.

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...

Problems solved by technology

However, liquid hydrogen and liquid oxygen cryogenic liquids have low boiling points and are very easy to evaporate. Under the harsh thermal environment on the lunar surface, a large amount of evaporation loss of cryogenic liquids will be caused. Therefore, it is necessary to use a cryogenic liquid storage system on the lunar surface to control the evaporation of cryogenic liquids.
