Doomsday Bunker Upgrade Chapter 372: Warm air

Because all the components have been prefabricated in advance, workers only need to assemble them, so the construction of the heating hub did not take much time.

Counting the time to lay the foundation, it took only two days to complete all the work.

After the installation of the heating hub was completed, Chen Xin originally planned to connect the pipelines on both sides before starting the heating hub after the return well at No. 7 Middle School was also completed.

After all, in addition to the problem of drainage, there is also the risk that a large amount of groundwater extraction may cause cavities in the rock formation and the formation of collapse. Under the current situation of difficult natural replenishment of groundwater, it is necessary to avoid excessive extraction of groundwater as much as possible. .

However, after consulting Professor Zhang's relevant knowledge, Chen Xin let go of these worries.

Extracting a large amount of groundwater will indeed cause cavities in underground rock formations, but this requires a long period of continuous extraction.

The geological collapse caused by groundwater extraction mostly occurs in areas where groundwater is pumped on a large scale all year round. In those areas, groundwater is used uncontrollably, and in areas with relatively poor water resources, precipitation is not abundant enough, and groundwater is long-term. If it is extracted and cannot be supplemented, underground cavities will be formed, causing geological collapse.

As long as it is not a large number of long-term extraction, it will not cause such serious consequences.

Although the geological structure of Lincheng is complicated, it is relatively stable. For many years, there has not been any geological disaster such as earthquake or collapse.

Under such circumstances, Chen Xin did not hesitate and chose to start the heating hub.

As the heating hub starts to operate, the underground hot spring water is pumped up with abundant thermal energy, and the heat is dissipated through the evaporative cooling equipment and then turned into cold water and discharged.

According to the design, this cold water should be piped to the return well, and then re-injected into the ground.

But since the construction of the return well has not been completed, the cold water can only be discharged naturally.

The stagnant water that Chen Xin feared would flow along the railway did not happen. Affected by the terrain of Linshi, which is high in the south and low in the north, the stagnant water was drained by the workers to the south of the railway station through pipes.

The south of the train station was originally the family area of ​​train station employees. It is only separated by a wall from the train station and can be reached by crossing the railway.

Further south, there are wasteland and a pond. This is a relatively low-lying place near the city. Although there is a lot of snow cover, the terrain has risen slightly, but if you measure the altitude, it is still a low-lying area. .

So after putting a water pipe on the gully above the railway and guiding the water pipe across the railway, you can safely discharge it here.

It is not only the cold water that has been dissipated, but also the water that is formed after the snow has melted.

However, the situation of water accumulation is not particularly serious, because the heating hub emits heat to melt the snow, and the ambient temperature also affects the melting of the snow, which causes the snow to melt at a slow rate. quick.

Just standing next to the snow pit, watching the heating hub at work emit a rolling heat wave, melting the surrounding snow little by little, and at the same time rising a stream of white "steam" around, it really makes People have a feeling of being in the steam age and feeling the beauty of heavy industry.

The reason why "steam" is produced is not that the temperature is too high, and the melting snow and ice directly turns into white steam, but that when the snow melts, a part of the water vapor evaporates into the air, and these small water droplets are in the air. After leaving the heating field of the heating hub, the pre-cooling quickly condensed and turned into tiny ice crystals.

The small ice crystals did not fall to the ground because they were too small and light. They were lifted into the air by the airflow, and naturally turned into white "steam".

Chen Xin reached out to wipe off the water vapor accumulated on the helmet, and finally showed a satisfied smile on his face as he watched the snow that was gradually dissolving.

The speed at which the heating hub melts snow is of course not as fast as the speed at which the snow evaporates instantly when the heating equipment is turned on in the game "Frozen Age", but watching the snow melt into water at a speed visible to the naked eye, flowing, Falling at the bottom of the snow pit, turning into stagnant water and being pumped away by the pump, still gives Chen Xin a very strong sense of satisfaction.

This is what he made, bringing the warmth back to the earth in this era, even though it is only this small place, it is still worthy of pride.

Thinking about this, Chen Xin walked down to the bottom of the snow pit. The standing water here has gone beyond the feet of the power armor, but Chen Xin didn't care.

Because this is to facilitate the pumping of water, it will allow it to accumulate so much, otherwise the water is too shallow, and the pump cannot **** water and it will be troublesome.

Through the environmental monitoring of the power armor, Chen Xin can clearly know that the temperature around the heating hub has reached 27°C, but because the surrounding snow is more than ten meters high, almost flush with the heating hub, At present, the area covered by the heating place is still only the snow pit, which has not reached the radius of 200 meters in Chen Xin's design~IndoMTL.com~ The small book pavilion used by book lovers has been hung up, and now basically all Reading app\ with mimi.

However, as the snow continues to melt, the snow pit has begun to become wider at the top and narrower at the bottom. As long as it continues, it will become a big bell mouth, like a sea bowl.

Looking at the rumbling heating hub in front of him, Chen Xin thought about it and opened the lock of the power armor, walked out of the power armor, and took off his helmet.

The warm, water-rich air rushed towards his face, causing Chen Xinqing to take a deep breath, letting the moist air inhale through his nose, filling his chest.

It's been a long time since I felt this way!

This feeling of standing outside and breathing the warm air freely!

Chen Xin exhaled a long breath, and then looked up at the heating hub that stood like a tower in front of him.

Thanks to it, the air around here is warm and humid, just like the summer days.

Compared to the slightly dry and cold air in the shelter, the air quality here is not necessarily much, but it feels completely different.

Just standing outside and breathing the warm, moist air is exciting enough.

After all, the whole earth is now a huge ice and snow hell. It is very rare and long-lost to be able to stand outside and breathe the warm air freely.

Feeling this kind of thing that was accustomed in the past, but now it has become very rare, after Chen Xin shook his head slightly, he also had a firm belief in his heart to promote it.

Let human beings return to the earth and get rid of their dependence on underground shelters. Chen Xin believes that with these heating hubs and the planned energy towers, he will definitely be able to do it in his lifetime.
