Chapter 280

In the early morning, when Chen Xin finished washing and took the elevator to the observation room on the top of the shelter, Han Ping and Han Ze were cooking a pot of thick hot soup around the stove. The smell of food wafted in the air, and the heat from the stove also slightly dispelled the cold in the room.

"Good morning, Han Ping, Han Ze. Did you sleep cold last night?" Chen Xin felt the temperature in the room for a moment and asked the Han brothers, who were wearing temporary exoskeleton protective clothing.

"Mr. Chen." When Han Ping saw Chen Xin come in, he quickly pulled his younger brother aside and stood up to greet Chen Xin: "it's OK. I can stand it in the room at night, but I have to turn on the heating of my clothes when I watch the night, otherwise I can't stand it."

After hearing Han Ping say so, Chen Xin motioned for them to sit down. Then he took a look at the observation window which has been blocked by the glass in the observation room. He shook his head and said helplessly: "it's good if you can stand it. No, you can go to sleep at night. It's too cold for anyone to come here in this bad weather. "

However, Han Ping still shook his head and said: "the more such weather is, the more vigilant we should be. People who can come out of this weather are either ferocious or can't live. They are very dangerous and must be vigilant."

Facing Han Ping's attitude, Chen Xin can't say anything about him, but he complains about the snowstorm without warning.

Not long after Li Tou and Ding Ning had been here before, there was a blizzard that night, and the temperature dropped sharply again. The temperature dropped from more than 30 degrees below zero, which was tolerable, to more than 70 degrees below zero, accompanied by a strong wind that could overturn an ordinary car.

The arrival of the blizzard without any signs, as if it is blowing up in an instant, before people have no reaction, it has swept everything.

Chen Xin can understand the appearance of this kind of weather. After losing the protection of vegetation and the regulation of atmospheric circulation, the weather system on the whole earth's surface has completely collapsed. The strong wind has lost its blocking and become more and more violent. The appearance of extreme weather is only one of the effects of the collapse of the weather system.

In the past, the cold wave in winter will cause a large-scale cooling of the whole country. Now that the weather system has collapsed, the cold brought by this snowstorm will also affect many places. What is different from the past is that once the temperature drops, it is difficult to recover.

Because the sun, the main source of heat on the surface of blue stars, has been blocked by dust, it is still very difficult for the temperature to recover even if the snowstorm dissipates.

At this time, the strong wind of more than 12 levels outside the shelter is whistling, rolling up countless goose feather and heavy snow. If there is still the sun, we can see the vast white scene of heaven and earth.

However, the snowflakes floating in the sky at this time are not ice crystals, but carbon dioxide snow formed by the liquefaction and condensation of carbon dioxide in the air at low temperature, which is commonly known as dry ice.

The extreme low temperature has obviously broken through the limit of most buildings to resist the cold. Even Chen Xin's upgraded shelter can't stand it, so Chen Xin has to turn on the heating system in the shelter to the maximum power to ensure the indoor temperature and the survival of indoor plants.

This also makes Chen Xin realize that the ground source heat pump as a heating equipment has a problem, it is affected by the formation temperature, and temperature limit.

Although there is no problem at present because his shelter is deep underground, if the snowstorm continues, the temperature will not rise again. The deep layer may not have any effect, but the temperature in the shallow layer will certainly decrease.

This will undoubtedly affect the ground source heat pump equipment, which mainly depends on the temperature of the shallow layer to obtain heat, and reduce the heating effect.

So if the temperature continues to drop, Chen Xin must consider using other heating methods in the shelter.

Now, the temperature in the upper observation room on the earth's surface is as low as 20 degrees below zero, which is the result of Han Ping and Han Ze's stove being on all the time.

It was because of the low temperature that Chen Xin wanted the two brothers to go to the lower level of the shelter. It was too cold up there. He was worried that the two brothers could not bear it.

But Han Ping insists on staying on it, and has been doing night watch work with his younger brother.

Chen Xin, who can't be persuaded, can only let Han Ping and his younger brother stay at the top of the shelter, but for the sake of safety, Chen Xin has prepared a stove and two sets of emergency protective clothing for them to avoid frostbite and damage in the low temperature environment.

With protective clothing, Han Ping and Han Ze actually feel that the temperature is tolerable. After all, they are wrapped in an electric blanket. In addition, there is a stove where they can cook hot food at any time to supplement their body heat. Apart from being a little hard at night, they are all OK.

However, Han Ping was still worried and asked Chen Xin, "Mr. Chen, our conditions here are so good and it's so cold. Is it colder in other places?"

"Other places? If you don't do a good job in keeping warm and cold, I'm afraid it's not just a colder problem, it's going to freeze to death. " Asked this question by Han Ping, Chen Xin shakes his head.The temperature of more than - 40 degrees below zero can still be met in the north of Yanguo, but the temperature of more than - 70 degrees below zero is already very extreme.

In this kind of temperature, the scene that the helicopter flying in the sky directly freezes down in the movie the day after tomorrow will really appear.

Even if there are buildings that can withstand the cold wind, if there is no heat source, the temperature drop is enough to freeze all life.

The urban area relies on coal-fired boilers for heating, which should still work normally in this weather. However, most of the shelters in the urban area are not deep underground, and most of the cold proof and heat preservation were temporarily renovated three months before the disaster, which makes Chen Xin very worried about the situation in the urban area.

But in this environment, even Chen Xin does not dare to go out. The snowstorm outside is enough to put any vehicle into a desperate situation. Even his modified tracked RV is difficult to guarantee no accident in this environment.

Maybe only the heavy-duty vehicles in wandering earth can cope with such bad weather?

Chen Xin thinks so in his heart, and his attitude of becoming more comfortable because of better living conditions has become nervous again, feeling the crisis of survival.

Although Chen Xin is able to live without food and clothing, it is not that he really has no survival crisis.
