The sudden drop in temperature has made the warmth and heating issues in the shelter serious.
Although the external temperature is -34°C, the fact that the temperature inside the shelter is still 7°C is enough to prove the excellent thermal insulation and cold resistance capability of the shelter, but this does not hide the fact that the temperature inside the shelter is already quite low.
It's important to note that there is also a greenhouse in the shelter, and if the temperature there is too low, it would affect the growth of crops.
While thinking about these issues and clearing ice from the small bunker, Chen Xin has to contemplate how to improve the heating and insulation of the shelter.
