Chapter 101 - 100 Microalgae-Based Ethanol Production
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.
Compared to the heating problem, insulation is not as troubling for Chen Xin, after all, his shelter is protected by over 200 meters of soil, and even the entrance has a thick layer of reinforced concrete and insulation, which leaves nothing to be desired in terms of insulation performance, as evidenced by the indoor temperature remaining at seven degrees.
If he wants to improve the insulation, Chen Xin thinks he only needs to upgrade the insulation material of the walls once more.
Regarding the choice of upgrading insulation materials, Chen Xin doesn’t have a specific idea, but if possible, he wants to replace the wall insulation with carbon aerogel.
Under normal temperature and pressure, the thermal conductivity of carbon aerogel can be as low as 0.013w/m·K, which is currently the lowest thermal conductivity of solid materials on Blue Star.
Compared to traditional polyurethane materials, it is more efficient and can still provide excellent insulation even in extremely low temperatures.
