Air conditioning system on the Chinese space station

The Thien Cung space station, located 400km above Earth, always has spring-like temperatures, providing an optimal environment for astronauts to live and work.

To keep astronauts safe from extreme temperatures in the space station, which can reach up to 150 degrees Celsius in direct sunlight and drop to -100 degrees Celsius in the dark, China's Thien Cung space station Quoc uses an advanced heat control system , CGTN reported on March 22.

The system uses closed fluid circuits in every corner of the cabin. Through the continuous circulation of special fluid inside the pipe, the system collects the heat generated from the equipment and astronaut, and then transports the heat through the circuit to the appropriate equipment and structures, Cool areas that are too hot and warm areas that are too cold.

Therefore, the system not only provides comfortable conditions for astronauts, but also ensures the normal operation of equipment and testing tools that require temperature control. This environment also allows growing vegetables on the space station.

Astronauts who grow vegetables on the station can not only study the effects of special space environments such as microgravity on plant growth and physiology, but also relieve their own stress and regulate physiological and psychological emotions in a positive direction. More importantly, they can collect food, oxygen and water.

The life-sustaining function of plants plays an important role in establishing a self-sufficient life support system on extraterrestrial life, enough to reduce the cost of providing necessities for long-term manned missions. . Research into alien life support systems is being focused on by space agencies.
