Chapter 374: 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 wait for the completion of the return well on the No. 7 Middle

School and connect the pipes on both sides before starting the heating hub.

After all, in addition to considering the issue of drainage, there is also the

risk of large amounts of groundwater being pumped out of the rock that may

cause caverns in the rock formations and forming collapses. In the current

situation where it is difficult to replenish groundwater naturally, excessive

pumping of groundwater should be avoided as much as possible.

However, after consulting Professor Zhang's relevant knowledge, Chen Xin let

go of these concerns.

Large amounts of groundwater pumping will indeed cause cavities in underground

rock formations, but it takes a long time and a large amount of continuous

pumping. If it is only a short time and the pumping volume is not large, the

impact will not be significant.

Because the extraction of groundwater causes geological collapse, most of the

events occur in areas where groundwater is extracted on a large scale all year

round. Those areas use groundwater uncontrollably. In addition, they are areas

with relatively poor water resources. The precipitation is not sufficient.

Groundwater has been extracted for a long time. Without supplementation, this

will form underground voids and cause geological collapse.

As long as it is not large and long-term extraction, it will not cause such

serious consequences.

Moreover, although the geological structure of Lincheng is complex, 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 heat energy, and the heat is dissipated by evaporative

heat dissipation 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 fact that Chen Xin was worried that the stagnant water would flow down the

railway did not happen. Affected by the high and low terrain of the

neighboring city, the stagnant water was drained by the workers to the south

of the train station through pipelines.

The south of the railway station was originally the family area of the

railway station employees. It is separated from the railway station by a wall

and can be reached by crossing the railway.

To the south is a wasteland and a pond. This is considered to be a relatively

low-lying place near the city. Although there is a large amount of snow cover,

the terrain has risen slightly, but if you measure the altitude, it is still a

low-lying area.

Therefore, after using 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 water accumulation situation is not particularly serious, because

while the heating hub emits heat to melt the snow, the ambient temperature

also affects the melting of the snow, which causes the snow to melt at a slow

rate.

Just standing next to the snow pit, watching the heating hub at work emit a

billowing heat wave, melting the surrounding snow a little bit, and at the

same time a white "steam" rises around it, it is really impressive It feels

like being in the steam age and feeling the beauty of heavy industry.

The reason for the “steam” is not that the temperature is too high and the

melted ice and snow directly turn into white steam, but when the snow melts,

part of the water vapor evaporates into the air, and these small water

droplets leave the supply. After the influence of the heating field of the

thermal hub, the pre-cooling quickly condenses and turns into tiny ice

crystals.

The small ice crystals did not fall to the ground because they were too small

and light. They were driven by the airflow and rose into the air, naturally

turning 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 when

the heating equipment in the "Era of Ice and Vapor" game is turned on, the

snow evaporates instantly, but watching the snow melt into water at a speed

visible to the naked eye, flowing and falling on the snow The bottom of the

pit, turned into stagnant water and pumped away by the pump, still gave Chen

Xin a very strong sense of satisfaction.

This is what he made, bringing warmth back to the earth in this era, even

though it is only this small place, it is still worthy of pride.

Thinking of this, Chen Xin walked down to the bottom of the snow pit. The

water here had already passed the foot of the power armor, but Chen Xin didn't

care.

Because this is to facilitate the pump to pump 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, it is almost flush with the

heating hub. The only area covered by the site is the snow pit, which does not

reach the radius of 200 meters in Chen Xin's design~www.mtlnovel.com~The small

book kiosks used by book friends have been hung up, and they are basically in

Use \\mi\\mi\\ to read \\app\\\\.

However, as the snow continues to melt, the snow pit has become wider at the

top and narrow 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

unlocking the power armor, walked out of the power armor, and took off his

helmet.

The warm and vapor-rich air rushed in, causing Chen Xinqing to take a deep

breath, letting the moist air ** into his body along his nose, filling his

chest cavity.

This feeling is really long gone!

This feeling of standing outdoors and breathing warm air freely!

Chen Xin exhaled a long breath before he looked up at the heating hub that

stood in front of him like a tower.

Thanks to it, the surrounding air is warm and moist, just like the past

summer.

Compared with the slightly dry and cold air in the refuge, the air quality

here may not be much better, but the feeling is completely different.

Just standing outdoors to breathe warm and humid air is enough to make people

feel excited.

After all, the whole earth is now a huge ice and snow hell, and being able to

stand outdoors and breathe the warm air freely is a very rare and long-lost

thing.

Feeling this kind of thing that was accustomed to 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.

To bring humans back to the earth and get rid of dependence on underground

refuges, Chen Xin believes that relying on these heating hubs and planned

energy towers, he will definitely be able to do it in his lifetime.
